Animal Repellers – Humane Animal Control

Pest infestation is a common thing in every home, with pests ranging from rats & mice to stray cats and dogs. Dealing with any pest is a challenge as most animal pests pose a potential threat to human beings; they can bite or scratch you as you attempt to remove them leading to deadly diseases such as rabies. The best thing to do is to keep your distance. This does not necessarily mean that you must hire a professional to do it for you. In fact, most if not all pest problems can be handled without the services of a professional. With one or two devices you will be able to repel pests from your home safely.

Dealing with pest issues by yourself also ensures that the animal pests are dealt with in a humane way that does not harm the animals nor the environment. Professionals are known to sometimes seek quick solutions that involve the use of harsh chemicals which may be harmful to the environment and even you, if you come into contact with them.

Pestrol has made handling animal pests by yourself easier by creating amazing gadgets and devices that are both Eco-friendly and humane to use. To help you deal with your animal pest problems, here are a few common pests and solutions created by Pestrol to help you deal with them.


These are the hardest kinds of animal pests to control. This is because unlike their larger counterparts, rodents are smaller and thus able to hide in spaces inside your home that you can never reach. Other than spreading disease, rats and mice will damage your property by chewing on wires, pipes, clothes and other items in the house. They may also have pests such as flies and ticks on them that could be introduced into your home causing more problems. They both have gestation periods of less than a month and will produce up to 12 litters at ago. This means that if control is not done in time, your house could be overrun by rodents.

Once you have noticed your house is infested with rodents, it is best that you act as quickly as possible. You can use one of several methods to remove them. Options include:

Rodent traps

Pestrol has developed several rodent traps that work well to trap rodents in a manner that is both humane and friendly to the environment. Some of these include:

Pestrol Rat/Mice Multi Catch. This trap comes in two variations; small and large. The smaller one works for mice while the large one works for both mice and rats. The trap can be re-used an unlimited number of times as all you have to do is release the trapped rodents and reposition the trap.

Pestrol Rat/Mice Multi Catch

Pestrol Mice Device – This is a mouse trap designed for small, narrow spaces that are not large enough for other traps. It is designed to catch multiple mice and can be re-used once the trapped mice are released.

Pestrol Mice Device

Traps offer a great solution as compared to poisons as they are animal specific (meaning they won’t catch anything else other than mice and rats) and will reduce the possibility of rodents dying and decaying in hard to reach places.

Rodent Repellers

Repellers are another viable option when it comes to dealing with rodents. Repellers will scare away rodents preventing infestation. Some repellers offered by Pestrol include:

The Pestrol Commercial Pest Repeller – This device will work well for both home and large scale commercial application. The device produces Ultrasonic sound that causes discomfort to rodents but not humans. Actually, humans can barely hear this sound. This device will scare away all rodents.


Pestrol Rodent Free – This device uses a combination of Ultrasonic, Electromagnetic and Ionic technologies to ward off rats from certain areas. Just plug in this device to a power source and let it do the magic!

Once possums invade your attic or underneath your house, you will never know quiet. These animals make a lot of noise and create a big mess in your home. They eat your garden plants and defecate all over your property. They can also disrupt the Eco-system by disturbing native birds in the area. So how do you get rid of possums? Well you could use one of two options:

Using a trap

The Pestrol Possum Trap comes in handy for this job. These traps enables you to trap, transport and then release the possum while maintaining safety for both you and the animal. The trap is built strong so that the trapped animal does not escape. This trap can also be re-used for a long period of time.

Using repellers

Repellers available for possums include:

The Pestrol Outside Animal Repeller – This nifty device repels possums from your home by emitting ultrasonic sound that is intolerable to possums but almost inaudible by humans. This device is very effective in scaring away unwanted animals from your property. This device can work continuously or use the inbuilt sensor to activate when an animal gets inside its range.

 Pestrol Outside Animal Repeller

The Pestrol Animal Motion Activated Water Jet Repeller. This device emits a five second bust of water to scare away animals detected by its inbuilt motion sensor. It is solar powered and only needs to be connected to an ordinary hose pipe for it to function. 4 AA rechargeable batteries are provided for power storage.

Pestrol Animal Motion Activated Water Jet Repeller

Dogs and cats

This problem can be very frustrating and especially so if you do not have a cat or dog of your own. Stray cats and dogs or maybe your neighbours’ pets may be wandering into your yard and messing up your gardens by defecating and digging around. The main challenge when dealing with cats and/or dogs is that traps cannot be used as the animal may just be the neighbours pet wandering around. Repellers are best suited for this job as they will only scare away the animals without trapping them. Some applicable repellers include:

Pestrol Animal Away – This solar powered device is fitted with a motion detector that goes off when an animal is detected within its range. It produces ultrasonic sound that will scare off unwelcome cats and dogs from your property. The solar energy is stored in rechargeable batteries for night time use.


The Pestrol Outside Repeller – This weather proofed device also works by emitting ultrasonic sounds that scare away animals. This model needs to be plugged in to a power source for it to function.

Cockroaches: Life Cycle and Control

The cockroach is amongst the most resilient insects. They are known to survive in harsh environments and can survive on very limited resources. Roaches can also go for up to one month without food (Source: It is this ability to survive in harsh conditions that makes cockroaches that hard to get rid of.


Tips To Prevent Cockroach Infestation In Your HomeCockroaches feed on both human and pet food leaving an offensive odour wherever they have been. Although they do not cause any disease natively, they can passively transport disease-causing micro-organisms on their bodies which could cause harm to humans. Some people may also get allergic reactions when they come close to these pests.

The life cycle of the cockroach

The cockroach life cycle is composed of three developmental phases namely egg, nymph and finally adult. The female cockroach produces an egg case called an ootheca. This case contains anywhere between 6 and 40 eggs. Depending on the species, the ootheca can either remain attached to the cockroach until the eggs are ready to hatch or deposited in a hidden place where the eggs will hatch.
After 6-8 weeks, immature cockroaches known as nymphs emerge from the case. They are mostly white in colour and will gain their brown colour as they age. These nymphs will feed and undergo a series of moultings over a period of one year as they develop into adults. The adult cockroach can live for up to one year (1).

How to control cockroaches

Like most pests, cockroaches invade your home in search of food, water and warmth. You cannot take away the warmth, but you can deprive them of food and water to make your house less hospitable to these pests. Some of the measures you can take to eliminate food sources include:

  1. Cleaning your house on a regular basis. A clean house – the kitchen especially – is key to cockroach control. Do not let dishes pile up in the sink or live food messes on the floor and appliances. Clean them up immediately so that cockroaches and other pests do not find anything to feed on.
  2. Keep all stored food in sealed containers. Leaving uncovered food out for long periods will provide food for these pests and that is something you do not want.
  3. Fixing your leaking taps. Leaking taps will provide water for the cockroaches in addition to wasting a lot of the precious resource.
  4. Covering your bins and taking out the rubbish regularly. Designate one rubbish bin for food and ensure that it’s always covered. Also remember to throw out the rubbish often.
    Although effective, the above measures cannot be solely relied upon to get rid of all cockroaches in your home. As I mentioned earlier, cockroaches are highly adaptive and can live in extremely harsh environments. It is, therefore, necessary to combine these passive measures with some professional products for the best results.

Possum Control in Your Home

Don’t let their looks fool you, although cute and cuddly, possums can be a real pain when they invade your home. In addition to the ruckus they cause as they go about their business inside your home, possums present a health risk as they can spread disease to humans and pets. Possums spread diseases through their urine and droppings.

Possums could also cause damage to your house when they chew on electrical wiring which is both a fire hazard and expensive to fix. There’s also a possibility that possums could introduce other pests into your home such as ticks and fleas.

The lifecycle of a possum

Possums are marsupials, meaning they carry their young in a pouch. They usually give birth in May and June after a gestation period of about 17 days.  A newborn possum is about 1.5 cm long and only weighs about 2 g. Despite the small size, the newborn can climb unaided through fur into the female’s pouch where it attaches to a teat.

The young possum will feed and develop for about 5 months while still inside the mother’s pouch. It will then spend another two months clinging to its mother’s back as she moves around. Usually, possums give birth to only one young at a time, which males do not participate in looking after.

By seven months, the young possum is mature enough to live independently and is fully grown by the tenth month. For females, breeding starts when they reach 12 months but males can go for up to 2 years.


Control and Prevention of the New Zealand Possum

The first step in possum control is prevention. Keep them out of your home and you won’t have to worry about getting rid of them. To keep possums out of your home you should:

–    Cover all openings that possums could use to get into the house. If it’s a vent, use a slotted metal vent cover to ensure that no animals get through.

–    Trim the tree branches near your home so that they are at least 10 ft from your roof. Possums are good climbers and could use them to get to your roof.

–    Protect low decks by installing grid screening and other suitable barriers.
Additionally, you can use professional animal repellers to keep possums out of your compound. Repellers in our catalogue include:

1.    The Pestrol Animal Repeller. This device uses ultrasonic technology and a strobe light to scare away all animals within its range. The device has a motion sensor that activates it when an animal gets within range.

bird repeller

2.    Pestrol Possum Repelling Spikes. These help prevent possums from climbing over and along your wall. The device only makes it uncomfortable to walk on the wall and does not harm the animal in any way.


If possums have already set up camp in your home you should use:

The Pestrol Possum Trap

This easy to use device enables you to capture troublesome possums and take them out of your house. The trap is built to ensure safety for both you and the trapped animal. The possum trap enables you to capture possums and release them a safe distance from your home so that they can go back to the wild.

Moth Control – Best Methods

Adult moths are not dangerous nor do they pose any significant health risks, but moth larvae cause damage to clothing, fur, leather, fabrics and to carpets. Larvae feed on fibres that are derived from animals including wool and silk. While moth larvae will feast on clothes and other items they prefer dirty or soiled fabrics over clean ones. This is a good reason to keep items that are susceptible to moth infestation clean to protect them from damage.

Do you have a moth infestation?

If you have a moth infestation it will be notable with a few different and obvious signs. First of all there will be adult moths located in darkened areas and they may fly around. If you open a dark closet and see moths inside, you need to take a closer look for larvae. Moth larvae are similar in appearance to maggots. They also may be in cases or silken tubes until they are developed enough to emerge from the casing.

The two most common types of moths are the webbing clothes moth which is about inch long with no distinctive markings and straw-coloured wings. The larvae are a creamy white colour and have a brown head and can be an inch long. They tend to make irregular holes in fabrics. The case bearing clothes moth is fond of imported animal fabrics. Adults are about 6 mm long and are a buff colour and feature three faint spots. The larvae are creamy white and up an inch long. The holes that they make in clothing are more regular in appearance.

Preventing moth problems and effective moth control

Clothes moths prefer a dark environment to lighted areas and the areas where you might see an infestation include under a bed, in cupboards or in wardrobes. Attics may also experience an infestation because items that may be a target for moths are often stored in boxes. Soiled clothing items are attractive to moths, so if clothes are to be stored they should be cleaned and then placed into sealed plastic bags to keep them safe.

It is important to inspect areas that are hidden from view like areas under furniture and wool rugs. Even if you vacuum on a regular basis you may still have soil remaining in the carpet that can be attractive to moths. It is important to use effective moth control methods that will get rid of moths once and for all.

Dogs – Control in Your Home

It’s quite frustrating when dogs keep straying into your yard and causing all sorts of messes. They dig around destroying your lawn and plants, and to make matters worse they also defecate in your garden or on your lawn, leaving you with the unpleasant task of waste disposal. If you have pets of your own, their behaviour might be affected negatively when a stray dog marks (pees) in your garden.

Other than the mess they cause, stray dogs can bring pests such as ticks, fleas and worms into your property which could be problematic for you especially if you have pets. Stray dogs can also spread other diseases such as rabies either to you or your pet. The danger of being bitten cannot be ignored either.

The life cycle of a dog

Dogs reach sexual maturity between the age of six and twelve months, but this can be slightly delayed in larger breeds. After mating, the female dog goes through a gestation period that lasts somewhere between 58 to 68 days.
The average litter consists of about six puppies, but the number widely varies between different breeds. Small dogs produce from one to four puppies per litter while larger breeds can average as many as twelve puppies.
The typical lifespan of a dog is anywhere between 5 and 13 years depending on the breed and the size of the dog, with larger sized dogs having a shorter lifespan.


Signs of a dog problem

If there is a dog intruding into your yard, you will notice the following signs:

  • Dog poop. Stray dogs must get a kick out of pooping in people’s yards because this is one of the most common (and most annoying) signs of a dog intrusion. If you happen to find dog poop in your yard numerous times, then you most probably have a dog problem that needs to be taken care of.
  • Dug up ground. Dogs love to dig – mostly to bury bones and other food items. If you find your lawn or garden has been dug up, then you most likely have a pest dog in your hands.
  • The dog itself. Sometimes you might catch the animal red-handed. If you happen to find it several times on your property, then you need to take action.
  • Dogs and their bones… if you keep finding these in your yard, the most likely culprit is a stray dog or dogs.

Controlling dogs

Although dogs are annoying at times, care should be taken so as not to harm them as you attempt to keep them off your property. The first step in control is prevention. If you can keep the dogs out of your yard in the first place, you will not have to worry about controlling them. Some of the measures you could take include:

  1. Remove water and food sources on your property. Similar to other pest intruders, stray dogs will be attracted to your property by readily available food and water.
  2. Remove any food sources in your yard such as your pet’s food and outdoor rubbish. Make sure you bins are covered as well as your compost pile and remove any water sources on your property.
  3. If you know the owner of the dog, alert them of their dog’s behaviour. The owner might not know that their dog is straying into your property so telling them might help ensure that this is prevented in the future.
  4. Put up a fence. If possible, erecting a fence around your yard might ensure that dogs and other wild animals do not enter your garden. The only downside to this is that it might cost quite a bit or may not be feasible in some situations.

How Do I Remove Household Pests?

A pest infestation is a problem every house owner will have to face at some point. Pests are not only unsightly to have around but could cause a host of problems to your family and property. Pests will cause the following problems when they invade your home:

  • They’ll damage property. Almost all pests will cause serious damage to property when they invade your home. They will damage clothing, furniture, electric wiring, electronics, and in extreme cases could even munch away your home – think termites.
  • They bite and sting. Pests such as fleas, ticks, bedbugs, wasps, and mosquitoes bite/sting painfully and could even trigger serious allergies in some people.
  • Spreading diseases. Pests spread a host of diseases either directly (through bites and excretes) or indirectly (through contaminated surfaces and food).
  • Bad smells. Some pests produce bad smelling excretes that can make it difficult for you to live comfortably in your home.
  • Pests can cause quite a ruckus when they invade your home. Nocturnal pests in your loft, for example, can keep you up at night as they go about their business.

It is because of these and several other reasons that pests should be kept out of the house.

How do I remove pests without using chemicals or pesticides?

If there are pests that have turned your home into theirs, there are several ways you can remove them without the use of chemicals. These methods include:

  1. There are pest traps for most kinds of pests whether small or big. Traps offer a humane and chemical-free way of removing pests from your household. Some traps (mostly those for larger pests such as possums and rodents) allow you to release the trapped animal outside without causing harm to it, while others (especially those for small pests such as flies and roaches) exterminate them in the process of capturing them.
  2. Using repellers. Professional animal repellers are chemical free and mainly use a combination of technologies such as ultrasonic sound and ionic energy to chase pests out of your home. Repellers are easy to use electrical gadgets that require very little user intervention once they have been installed.

Natural repellers such as coffee grounds, peppermint, ammonia, and vinegar can also be used to keep pests out of your home.

  1. Reducing the humidity in your home. Pests, especially insects, love places with high humidity. Fix leaky plumbing, leaky roofs and improve ventilation in your home to keep the humidity levels low so as to make it difficult for pests to survive in your home.
  2. Removing clutter. A cluttered house provides the perfect dwelling for numerous pests. That’s because clutter gives pests places to hide and build their nests. Keep your things in order to remove pests from your house. Ensure that things that you do not need are disposed of, and the things that you do require are neatly organised.
  3. Keep a clean house. Pests come into the house in search of food and water. Make sure that your house is always clean by vacuuming and sweeping it regularly especially in areas where food is consumed and prepared. Make sure to do your dishes as soon as you finish using them and keep your trash bins tightly covered.
  4. Eliminate food sources. Keep all your food in sealed containers preferably ones made of glass or metal to ensure pests cannot feed on it. Also remove pet food and drink after they finish feeding.

Pests can be stubborn when they invade your home, but by using these methods, you can ensure that they don’t stick around long enough to cause too much trouble.

If it’s too late and you already have a pest problem, then pest control products will help.

How Do I remove Pests From The Garden

Pests can cause a number of problems when they invade your home garden. They will damage your plants, dig up your lawn, defecate on your property leaving a stinky mess for you to clean up, and can cause a lot of discomfort for your family as well as your pet.

Some of the common garden intruders in New Zealand include dogs, possums, birds, mosquitoes, and cats among others. Some of these pests could even go as far as getting into your home causing additional problems for you and your household.

Signs of a garden pest problem

Some of the signs you will notice when you have a garden pest problem include:

  • Damaged plants. Some pest intruders such as possums will munch on your garden plants causing serious damage to them.
  • Holes in the soil or lawn. Cats and dogs like digging up soil which could damage your lawn as well as plants. If you keep finding dug up soil in your garden, then you probably have a pest intruder on your property.
  • Animals in your garden. If you are lucky (or unlucky, depending on how you look at it), you might catch sight of the actual intruding animal while it’s in your garden.
  • Animal poop in your garden will indicate that you probably have some unwanted guests when nobody is at home.
  • Animal noises. Birds, dogs, and cats can make noises during the day and at night which will not only cause you sleepless nights but point to a pest problem that needs to be resolved.

If you have noticed any of these signs, then you need to take action to get rid of the stubborn pest that has made your garden their play area.

How do I remove pests from my garden?

The first thing you need to do when you notice pest activity in your garden is to identify what kind of pest you are dealing with. Some, such as birds, are pretty easy to identify as they are not very discreet. But for others, you might be required to do some detective work to know exactly what you are dealing with.

Once you identify the pest, you have several options for removing the pests to select from depending on the pest and your preferences. These include:

  1. Animal repellers. These are devices that produce irritating stimuli to ward off any pest intruders from your garden. They can either be motion activated or could go off at user-set time intervals. Animal repellers could also use visual stimuli that scare away the pest such dummies resembling predatory birds to scare away bird pests. Other stimuli used by repellers include water jets, ultrasonic sound, audible sound and strobe lights. View our repeller products >


  1. Physical barrier. Putting up a barrier such as a fence around your garden could also help keep away larger pests such as dogs from getting into your home. Animal spikes installed on existing fences could also keep pests such as possums and cats (that are pretty good at climbing) from getting over the barrier. View our animal spikes >


  1. Removing pest attractants. The majority of pests will come into your yard in search of food and drink. Eliminate sources of these attractants and pests will have no reason to invade your property. Keep your yard clear of food by cleaning up after barbecues and after you eat outside. Also, drain water sources and fix leaky plumbing in and around your garden to ward off pests.


  1. Keep your garden clutter free. A cluttered garden provides ideal shelter for intruding pests. Get rid of unnecessary items from your garden to ensure that pest intruders have nowhere to hide. Also make sure that your garden is well maintained by mowing the lawn and trimming overgrown bushes and plants that provide good hiding spots.

Pests could cause quite a mess and restlessness when they invade your garden, but using one these methods, or a combination of several, will ensure that they leave and stay out for good.

Controlling Birds On Your Property

Birds might seem harmless, beautiful and even majestic out there in the wild, but they can be a real nuisance when they invade your property.


Although they are not directly harmful to humans (mostly) and will generally coexist peacefully with us, they can cause a lot of problems when present in large numbers near human inhabitations. It is these problems caused by birds that make us forget their beauty and splendour and regard them as pests that need to be gotten rid of.
A number of problems are associated with an avian infestation. Here are the major ones:

1. Property damage. Birds will damage your property with these two things:

  • Droppings. Bird poop causes the most damage to property mostly due to the uric acid (of pH 3 – 3.5) it contains which corrodes numerous materials including steel, paint, and stone. Birds will also plaster the area they infest with guano causing the structure or building to lose its aesthetic value.
  • Nests. Birds will construct nests on your property for shelter using grass and straw. These nests can clog gutters and roof drainage resulting in a damaged roof. Nests constructed in vents will also hinder air circulation in buildings while those constructed near electrical installations pose a potential fire hazard.

2. Health risks. Bird droppings contain bacteria and fungi that when introduced to the human body through inhalation or ingestion could cause serious illnesses.

3. Noise. Birds are very noisy when they gather in large numbers which could make for less than ideal working conditions as well as interrupt other activities.

4. Accidents. Fresh bird poop is very slippery and could cause slip and fall accidents that could result in serious injuries. Accidents in your business premises could also expose your business to liability suits that could prove costly.

5. Food damage and contamination. When they invade farms, warehouses and food stores, birds will contaminate and destroy food making it unfit for consumption.


Bird pests common in New Zealand

Some of the common bird pests in the country include:

  1. Feral pigeons or Columba liva – Once domesticated for food, these birds later turned wild and have increased in population and now account for most of the bird-fouling of buildings and statues today.
  2. Red-billed Gull. These are large and aggressive birds mostly found in coastal towns and cities. The noise, mess, and smell they bring to the areas they inhabit make them a great nuisance.
  3. Sparrows. Nicknamed the “flying mice” these birds cause a lot of damage to stored food. They also pose a big health risk as they contaminate food for both humans and livestock.
  4. Starlings. These have a tendency to gather in large numbers and build nests in roofs and eaves. They bring dirt, odour and noise to the buildings they infest.


The life cycle of a bird

Shortly after fertilisation, the female bird identifies a place where she can lay her eggs – depending on the species, this will either be in a nest or a hole in the ground. A great number of birds prefer to build nests shaped like plates, mounds or domes to live and breed in.

The eggs require to maintained at a certain temperature (or incubated) for them to develop. Incubation begins immediately after the female bird lays her last egg and will last until the final one hatches.

Incubation duties are shared between the two parents in monogamous species while one parent takes the responsibility in species that practise polygamy. The warmth passes from the bird to the eggs through patches of bare skin on the bird’s breast and abdomen called “brood patches”. The eggs will take between 10-80 days to hatch depending on the species.

Chicks are either brought up by a single parent or both in polygamous and monogamous species respectively.

Controlling birds

Prevention is the first step for controlling any pest and birds are no exception. Like most pests, birds are attracted to your property by food. Make sure you dispose of your garbage in covered bins and that there is no food littered on your property.

Although getting rid of food sources around your property is a good way of reducing the chances of a bird infestation, birds could still invade your property requiring more targeted control methods.

Because of their importance to the ecosystem (and sometimes legislation), only humane bird control methods that don’t harm the birds can be used to keep them at bay. The most used include bird control spikes and bird repellers that use audio, visual or physical stimuli to scare away birds.

Bird control spikes

Bird spikes are a very effective, humane bird deterrent, lso called roost modifications, anti-roosting spikes or simply bird spikes. They can either be made using UV resistant polycarbonates, stainless steel, or a combination of the two materials. Bird spikes consist of upward projecting rods (or spikes) attached to a solid base.


Anti-roosting spikes prevent bird infestations by making it impossible for birds to land on buildings and structures. The length and density of the spikes are determined by the size of the bird you want to protect your property against with larger birds requiring long sparsely packed spikes and vice versa for smaller birds.

Bird spikes can be used to protect street lighting, building ledges, pipes, commercial signage, roof apex among other bird roosting sites.


Bird spikes are very simple devices which makes them pretty easy to install. For spikes with a polycarbonate base, specialised adhesive is used to attach them to the structure to be protected while fasteners are used for bird spikes with a steel base.

Benefits of using bird spikes

Using bird spikes for controlling birds is beneficial in the following ways:

  1.  Discreetness. Bird spikes are very hard to see from a distance which makes them good at preserving the aesthetic of the protected building or structure.
  2. Easy installation. Because they are not complicated devices, installing them is quite straightforward and can be done by the user.
  3. Low maintenance. Bird spikes require minimum maintenance once they have been installed. All you need to do is check periodically whether they have come undone.
  4. Humane solution. Bird spikes do not cause any harm to the birds they are protecting against.

Other bird repellers and deterrents

Although bird spikes are very effective, they are mostly limited in the areas they can be used which mainly consist of buildings and structures. Other repellers and deterrents for other situations include:Sound repellers

These use either ultrasonic sound (inaudible to humans) or “normal” audible sound to scare away invading birds. The devices either use motion triggers for activation when birds come around or go off at a set time interval.
Ultrasonic bird repellers produce a high-frequency sound ranging between 15kHz and 25kHz. This high-frequency sound is inaudible by humans but disorients, confuses and intimidates birds. But other than making them uncomfortable, the sound does not harm the birds.


These devices are designed to be weatherproof because they are meant for outdoor use. A combination of solar and rechargeable batteries is used to power them so that they can work without the need to plug them into a power source.

Sound repellers are good for protecting large outdoor spaces such as marinas, farms, gardens, orchards, and yards. Audible sound repellers are limited for use in areas where short bursts of loud noises can be tolerated.

Installing bird sound repellers is easy and does not require any technical knowledge or skills. Just position the device in a good location with access to sunlight and you are done.

Benefits of using sound repellers

These are:

  1. Protection for large areas. Sound can travel for quite a long distance which makes these repellers ideal for protecting expansive areas such as orchards and farms.
  2. Easy installation and use. Sound repellers are easy to install and use. They require very little user intervention after the initial setup.
  3. Additional protection from other pests. These repellers will also scare away other intruding pests such as feral cats, dogs, and possums.
  4. Round the clock protection. Because they have batteries, sound repellers although reliant on solar will work effectively even at night.

Visual deterrents

These exploit the birds’ eyesight to frighten them. Some resemble predatory birds like owls, others human beings, while others – like holographic tapes – reflect light dramatically to a scare birds off your property.

Visual deterrents can be used to protect beaches, ponds, balconies, farms, and gardens. Because they need to be seen, visual deterrents are not effective after the sun goes down.

As for installation, no special skills or equipment are required to install them and can be done DIY style.

Benefits of using visual deterrents

Visual deterrents are:

  1. Quiet. These deterrents unlike sound repellers don’t emit any sound and are ideal for places where silence is required.
  2. Humane. Visual deterrents are humane and don’t cause any harm to the birds.
  3. Low maintenance. After you have installed them, visual deterrents don’t require any other alteration; just a periodic check to see if they are still in place.
  4. Cheap. These are cheap to buy and install.

Physical repellers

This kind of repellers use a physical medium like a water jet to startle birds off your property. Similar to sound repellers, these also rely on motion detectors for activation and use a combination of solar and rechargeable batteries.

They work well for small areas such as vegetable patches and yards. Some like those that use a water jet are limited to areas where moisture is not a problem.

These bird deterrents are designed for consumer use and will therefore not require specialised skill to install.

Benefits of using physical repellers

Physical repellers are:

  1. Environmentally friendly. Physical repellers don’t use or emit any substances that could harm the environment.
  2. Safe. These are safe for humans pets and the birds they are scaring away.
  3. Effective. A deterrent that “touches” the bird is more effective than those that don’t.
  4. Good at keeping other intruders away. A physical deterrent will be set off by any other intruding animal making them quite good for broad pest control.

Each of these options will only work well if deployed in a suitable situation. Analyse carefully the area or property you want to protect before settling on one to ensure that the control method you select is effective for that particular circumstance.

Do DIY Pest Control Products Really Stack Up Against Professional Pest Control?

Nobody likes to have pests around, they damage your food and property, bite painfully, cause a huge ruckus and generally make your life miserable. And that’s not all, pests also pose a great health risk to both humans and pets as they are capable of spreading diseases.

Once pests get into your property, they multiply quickly to have the whole place overran within a few weeks. This is why it is crucial that you take control action as soon as you notice these unwanted guests.

Taking quick action is easier said than done as the cost of professional pest control keeps a lot of people from dealing with the problem early enough. But you no longer have to call in a professional pest control service to deal with your pest problem. Why not do it yourself and save yourself some money?

DIY Pest Control vs. Professional Pest Control

In the earlier days, calling in an exterminator to take care of your pest problem was a common thing. A lot has changed since then. Thanks to advancements in science and technology, pest control is no longer a technical task and can be done by anyone.

Modern DIY products are easier to use, safe, and just as effective as those used by professional pest control companies. With just a few instructions and the right products, the average person can become a pest control specialist and take care of their own pest issue.

Benefits of DIY pest control

There are numerous advantages of doing your own pest control. These include:

  1. Reduced costs. With DIY pest control, you are not paying for someone to come to your property and take care of the pest problem for you. This is actually what makes professional pest control services so expensive – because you are paying for someone’s time and expertise. Doing the job yourself will help reduce the overall cost of pest control as you’ll only need to spend money on acquiring the pest control products.
  2. You get to choose the products to use. When you call in an exterminator, they’ll bring their own equipment and chemicals, and you won’t have any say in the matter. Some of these chemicals might be of poor quality or even harmful to you or your pet. With DIY pest control, you get to choose and buy your own products and ensure that they are applied as recommended for maximum safety and effectiveness.
  3. You can keep track of treated areas. In households where small children and pets are present, safety is extremely important. Since you cannot tag along as the exterminator does their job, it will be impossible to tell areas and items that have been exposed to the chemicals being used. This makes keeping your family safe from these chemicals after the job is done very difficult. When you do your own pest control, however, you will know which areas to keep pets and children out of and can protect sensitive items from the products you use.
  4. Privacy and discreteness. It might be difficult to let strangers into your property because you can’t really tell what their intentions By controlling pests yourself, you can retain the privacy you desire. Sometimes discreetness might also be required which DIY pest control provides.
  5. As mentioned earlier, pests need to be dealt with as soon as they are identified to prevent the infestation from growing and mitigate damage to property. Because of hectic schedules, it can be difficult to find time for an exterminator to visit. With DIY products, you can just take care of the pest problem at your own convenience.
