How to get rid of birds

bird-pestsBirds are beautiful creatures when they are in their natural habitats but can quickly become a problem when they invade your home. Their droppings can corrode metals, stone and paint while their nests can clog roof drainage and ventilations. And that’s not all, birds also make a lot of noise and could spread diseases to humans through inhalation or ingestion of their droppings.

Identifying a bird problem

A bird infestation is pretty easy to identify. In addition to the birds, other signs include nests, droppings and bird noises.


Birds, like most pests, come to your home in search of food and water. Ensure that your property is food free to avoid attracting birds and other pests. Cover your garbage cans and clean up any food that is dropped in your yard.

Controlling birds

Installing a fishing line or a thin steel wire a few inches above and along your roof’s apex will deter birds from perching and roosting there. It’s simple effective and easy to install. This, however, will not prevent birds from invading the rest of your property.

How to get rid of cats

cat-pestsCats as pests? It’s hard to believe that this cute and cuddly creatures can be classified as pests but wait until they invade your property. They turn your yard into their litter box, dig up lawns and gardens and can agitate your own pet making it uncomfortable in its own home. Intruding cats can also bring other pests such as fleas and ticks into your home.

How to identify a cat problem

You will know you have a stray cat problem when you see a strange cat hanging around a couple of times or when you often find cat litter and dug up soil in your yard.


Cats come into your property in search of food and shelter. Cover all areas that provide shelter to stray cats such as beneath porches and decks and remove all food sources to keep your property cat free.

Controlling cats

Natural scents such as citronella, lavender, garlic and citrus spray can be used to deter cats from coming into your property. These are however not 100% effective, for better results you should use professional products.

dog-pooDogs can cause quite a bit of a headache when they show up on your property. They dig around your lawn and garden, and defecate there leaving you with a very unpleasant mess to clean up. In addition, stray dogs can also cause distress to your own pet when they show up at your home.

How you know you have a dog problem

Keep your property free of food and water that could attract animals to your house.

How to get rid of possums

possum-pestThey might seem cute but these animals can cause a lot of disturbance when they invade your property. In addition to the noise they make, possums could also bring other pests such as fleas and ticks to your home.

Signs of a possum infestation

Possums usually hide under decks, in the basement and attic. Noises coming from these areas could indicate a possum infestation. Investigate any strange noises to confirm an infestation.


Possums will get into your home through holes and openings in walls. Inspect your house and cover all holes and cracks that could be used as entry points. Screen low windows and decks to prevent possums from getting under them. Possums are also good climbers so trim tree branches so that they are at least 10ft from your roof.


Spraying a solution of one cup molasses, a liter of water and a splash of dish washing detergent on your leafy plants will help prevent possums from munching on them. Possums dislike this taste and will leave your property if there is nothing to eat.

How to get rid of rodents

rodentsRodents are one of the most dangerous pests that could invade your house in terms of the damage they cause. Rodents gnaw on furniture, fabrics and virtually anything they come across. Rodents are also known to transmit diseases to humans.

How to identify a rodent infestation

Because rodents are nocturnal, seeing them is quite difficult.  This means that you will have to rely on other signs to identify a rodent infestation. Some of the signs you should look for include tracks and grease marks along walls, damaged property, holes on walls, as well as noises coming from your attic, walls and beneath the floor.


Rodents come into your home for two reasons; food and shelter. Maintaining a clean house and keeping your food in secure containers – preferably ones made from metal or glass – will ensure that rats have no reason to stick around. Also, inspect your house and seal all holes that rodents can use to enter. Remember, rodents can squeeze through the tiniest of spaces.


For a natural homemade rodent control solution, put a few drops of peppermint oil on cotton balls and place them where the pests have constructed their nest. Rodents find this smell very unpleasant.

How to get rid of flies

fly-problemFlies are very irritating, they buzz and hover around creating great discomfort. And because of their indiscriminate feeding behaviour, flies can also contaminate food as they jump from one food source to the other.

Identifying a fly infestation

Fly infestations are quite conspicuous and hard to miss. The flies will swarm around making it very easy to identify them.


Keeping your place clean will help prevent a fly infestation. Clean food related messes and spills immediately, keep your dishes clean and cover your garbage bins.


Flies often find entry into your home through open doors and windows, keeping them shut will deny them entry. This might, however, be hard to do during hot weather which is when fly populations are at their highest.

Signs of a cockroach infestation include cast skin, egg cases, a foul musty smell coming from their dwellings and cockroach droppings.


Cockroaches are most at home in dirty, cluttered places. Keep your house clean and tidy to discourage cockroach infestations. Do your dishes before going to bed, vacuum your house often (especially the kitchen) and keep your bins covered.


Cockroaches are some of the most resilient creatures on earth which makes controlling them a bit of a problem. With the right products, however, control can be done quickly and effectively.

How to get rid of silverfish

silverfish-problemThese are small silver to gunmetal coloured insects that feed on dextrin in adhesives, sugar, starches and other carbohydrates. They will damage your photos, books, carpets and clothes made from natural fabrics such as wool, cotton and silk.

Identifying a silverfish infestation

Silverfish are unique insects that can be easily identified by their silvery body and fish-like movements. They have a carrot like shape that narrows from the head to the tail terminating with three tail-like appendages at the rear. Other than spotting the actual insects, you might encounter these signs: damaged books, photos and fabrics.


Silverfish usually get into your house through holes in your walls. Inspect your house and cover them. Also, install door sweeps to protect the space below doors. Clearing leaves and other damp materials near your home will also reduce the chances of an infestation.


Although silverfish can survive in a variety of environments, they prefer living in areas with high humidity. Using dehumidifiers will make conditions less favourable for them to thrive.

How to get rid of mosquitos

mosquito-biteMosquitoes will keep you up at night with their painful bites and the sharp, irritating noise they produce as they fly around. Additionally, mosquitoes are dangerous disease vectors transmitting diseases such as Dengue fever, Filariasis, the West Nile Virus and Yellow Fever.

Identifying a mosquito infestation

Mosquitoes can be identified by their most prominent features which are a narrow body, long thin legs and a prominent mouthpart known as the proboscis.


Other than blood, mosquitos also feed on plant sap. Clear all overgrown vegetation and mow your lawn regularly to deny mosquitoes food and shelter near your home. They also require water to breed and draining nearby stagnant water will help control their population.


Keep doors and windows that are not screened shut at night when mosquitoes are most active to prevent them from coming into your house.

We recommend the following mosquito control products:

It’s quiet and effective.

How to get rid of moths

Adult moths are highly attracted to light and will be seen flying around lighting fixtures. They resemble butterflies in physic but lack the brilliant colours worn by their close relatives.


Moths can be brought into the house hidden in clothes, furniture and food so inspect these items before you bring them into your house. Switching off outdoor lights when they are not in use will help reduce the number of months around your home.


Using lavender will help extrude moths from your home. This method is however not effective on larvae which are the most destructive.

Identifying a spider problem

A spider infestation is very easy to detect, you’ll either encounter the eight-legged creatures crawling around or see the numerous webs they spin.


Cover cracks and holes on walls that may provide entry to spiders and screen all the vents. Keeping unscreened doors and windows closed will also help.

How to get rid of wasps

wasp-controlWasps sting painfully resulting in swelling around the affected part and uncomfortable irritation to the skin. For some people, though, the allergic reactions might be severe and lead to fatal symptoms that require immediate medical attention.

Identifying a wasp problem

Wasps are active during the day and can be seen flying around your property. All wasp species share some common characteristics which include a pinched waist (known as a petiole) and a pointed lower abdomen.


Seal all holes, cracks and crevices that wasps can use to get into your home. Keeping your doors and windows shut if they are not screened will also help keep wasps out.


Wasps are very territorial creatures that will not settle in an area with another colony. A fake wasp nest will give the illusion of another colony. Crumple a brown grocery bag and hang it outside your house to keep wasps away.
