How Bird Spikes Can Protect Your Property from Pest Birds
Birds can be a welcome sight in many outdoor environments, but when they begin roosting, perching, or nesting on buildings, they can quickly become a costly nuisance. Across New Zealand, property owners regularly deal with problems caused by pigeons, sparrows, starlings, and other pest birds.
Bird droppings, nesting materials, blocked gutters, noise, and damage to buildings are just some of the issues that can arise when birds repeatedly use the same areas of a property.
Fortunately, bird spikes provide a simple, humane, and long-lasting solution for preventing birds from landing on ledges, fences, signs, roofs, and other common perching areas.
In this guide, we’ll explain how bird spikes work, where they can be installed, and how the Pestrol S5 Narrow Base Bird Spikes and Pestrol S6 Wide Base Bird Spikes can help protect your property from unwanted bird activity.
Why Pest Birds Are a Problem
While birds play an important role in the environment, certain species can become problematic when they begin gathering around homes, commercial buildings, warehouses, schools, and public spaces.
Common problems caused by pest birds include:
- Bird droppings on buildings and walkways
- Blocked gutters and drains
- Damage to roofs and building materials
- Noise from large roosting populations
- Contamination of outdoor dining areas
- Nesting in unwanted locations
- Increased cleaning and maintenance costs
Over time, these issues can become expensive and difficult to manage if preventative measures are not put in place.
What Are Bird Spikes?
Bird spikes are physical deterrents designed to prevent birds from landing, roosting, or nesting on specific surfaces. Contrary to popular belief, bird spikes do not harm birds. Instead, they make the surface uncomfortable and unsuitable for landing, encouraging birds to move elsewhere. Because they provide a physical barrier, bird spikes are one of the most reliable and low-maintenance bird control solutions available.
How Bird Spikes Work
Bird spikes create a barrier that prevents birds from comfortably landing on ledges, beams, signs, gutters, fences, and other structures. When birds cannot find a stable place to perch, they typically move on and seek alternative locations. Unlike bird repellents that may require ongoing application, bird spikes provide continuous protection once installed.
Benefits of Bird Spikes
Humane Bird Control
Bird spikes are designed to deter birds without causing injury. They simply prevent birds from accessing preferred perching locations.
Long-Term Protection
Once installed, bird spikes can provide ongoing protection with very little maintenance.
Reduces Cleaning Requirements
Preventing birds from landing helps reduce the accumulation of droppings and nesting materials.
Suitable for Residential and Commercial Properties
Bird spikes are commonly used on homes, warehouses, factories, offices, schools, shopping centres, and public buildings.

- Fence tops
- Air conditioning units
- Security cameras
- Lighting fixtures
- Commercial building ledges
- Gutters and roof edges
Identifying the birds’ preferred resting locations is often the key to successful bird control.
Choosing the Right Adhesive for Bird Spike Installation
Using the correct adhesive is just as important as choosing the right bird spikes. A high-quality, weather-resistant construction adhesive will help ensure the spikes remain securely attached for years, even when exposed to New Zealand’s changing weather conditions.
For many installations, a high-quality polyurethane or hybrid polymer construction adhesive suitable for outdoor use is a popular choice. Always ensure the adhesive is compatible with both the installation surface and the bird spike base, and follow the manufacturer’s instructions.
Preparing the Surface
Before applying any adhesive, thoroughly clean the installation surface. Remove all bird droppings, nesting material, dust, grease, loose paint, moss, and other contaminants. The surface should also be completely dry before installation, as moisture can reduce the adhesive’s ability to bond properly.
Applying the Adhesive Correctly
Apply the adhesive in accordance with the manufacturer’s instructions, ensuring there is sufficient coverage along the bird spike base to create a secure bond. Avoid using only small dabs of adhesive, as this may not provide adequate contact or long-term holding strength.
Firmly press each strip into position and apply even pressure along the entire length of the base. This helps spread the adhesive evenly and creates maximum contact with the surface.
After installation, allow the adhesive to cure fully before the spikes are exposed to heavy rain, strong winds, or disturbance. Always follow the curing times recommended by the adhesive manufacturer.
How to Install Bird Spikes
Installing bird spikes is a simple DIY task that requires only a few basic tools. Correct installation is important to ensure the spikes remain secure and effectively prevent birds from landing.
- Clean the surface. Before installing the bird spikes, remove any bird droppings, nesting materials, dirt, grease, or loose debris. A clean, dry surface allows the adhesive or fixings to bond properly.
- Measure the area. Measure the length of the ledge, roof edge, fence, or other surface you want to protect. This will help you determine how many strips of bird spikes are required.
- Test the fit. Position the bird spikes along the surface before securing them. If required and permitted by the product design, the plastic base may be trimmed to suit the installation area while maintaining adequate spike coverage.
- Secure the spikes using a suitable outdoor construction adhesive. Depending on the installation surface, screws, rivets or cable ties may also be appropriate fixing methods.
- Allow the adhesive to cure. If using adhesive, follow the manufacturer’s recommended curing time before exposing the spikes to heavy rain or disturbance.
- Inspect the installation. Once installed, check that the spikes are firmly attached and that there are no gaps where birds could still perch. Periodically inspect the spikes and remove any leaves or debris to keep them working effectively.
When installed correctly, bird spikes provide a long-lasting, low-maintenance solution that helps deter birds from landing, roosting, and nesting without causing them harm.
Temperature and Weather Conditions
For the best results, install bird spikes during mild, dry weather. Most outdoor construction adhesives bond and cure more effectively when applied in moderate temperatures rather than in very cold, extremely hot, or wet conditions.
Avoid installing bird spikes during rain or when the installation surface is damp, as moisture can reduce the adhesive’s ability to bond properly. Very cold temperatures may slow the curing process, while excessive heat can cause some adhesives to cure too quickly before a strong bond is achieved.
If possible, choose a day with dry weather and moderate temperatures, and always follow the temperature and curing recommendations provided by the adhesive manufacturer. Allow sufficient curing time before exposing the bird spikes to heavy rain, strong winds, or regular bird activity.
Checking Your Installation
Once the adhesive has cured, gently check that each strip is firmly secured. Bird spikes should sit flat against the surface with no lifting or movement along the base. Periodically inspect the installation, particularly after severe weather, and remove any leaves or debris that may accumulate between the spikes.
Taking the time to prepare the surface properly and use a suitable outdoor adhesive will help ensure your bird spikes provide reliable, long-term protection against unwanted bird activity.
Surfaces That May Not Bond Well
While construction adhesives work well on many common building materials, some surfaces may require additional preparation or mechanical fixings instead of adhesive alone.
Adhesives may not bond reliably to:
- Dirty, dusty, or greasy surfaces
- Loose or flaking paint
- Wet or damp surfaces
- Some plastics with low surface energy (such as polyethylene or polypropylene)
- Heavily textured or uneven surfaces that prevent full contact
For these situations, screws, rivets, cable ties, or other suitable fixings may provide a more secure installation. If you’re unsure whether adhesive alone is appropriate, consult the adhesive manufacturer’s recommendations for your specific surface.
Why Early Bird Control Matters
The longer birds continue to use a location, the more established their behaviour becomes.
Birds often return to familiar roosting sites repeatedly, which means small bird problems can quickly grow into larger infestations.
Installing bird spikes early can help prevent:
- Large accumulations of droppings
- Nesting activity
- Blocked gutters
- Building damage
- Ongoing cleaning costs
Residential Applications
Many homeowners use bird spikes to protect:
- Roofs
- Pergolas
- Outdoor entertaining areas
- Fences
- Window ledges
- Garden structures
Bird spikes help keep these areas cleaner and reduce unwanted bird activity around the home.
Commercial Applications
Bird spikes are also widely used in commercial environments where bird activity can impact appearance, cleanliness, and maintenance costs.
Common commercial applications include:
- Warehouses
- Factories
- Shopping centres
- Office buildings
- Schools
- Hospitality venues
By preventing birds from landing, businesses can often reduce cleaning costs and improve the appearance of their premises.
Choosing the Right Bird Spike
The best bird spike depends largely on the width of the surface being protected. Narrow ledges and smaller structures are often suited to the S5 Narrow Base Bird Spikes, while wider ledges and larger commercial structures may benefit from the greater coverage offered by the S6 Wide Base Bird Spikes. Selecting the correct spike width helps maximise effectiveness and coverage.
