Bird spikes, also known as anti-perching devices, are a common solution to deter birds from landing and nesting in unwanted areas. However, professional installation is often recommended to ensure the spikes are properly fitted and meet safety standards. This article will explore who can legally and safely install bird spikes.
What are bird spikes?
Bird spikes, sometimes called anti-perching spikes or pigeon spikes, are devices designed to prevent birds from landing and gaining a foothold. They consist of parallel rows of stainless steel or polycarbonate spikes pointing upwards. The spikes are spaced close enough that birds cannot land comfortably between them.
Bird spikes provide a passive and humane solution to bird problems. They do not harm birds but simply discourage them from perching or nesting in a particular spot. When properly installed, bird spikes can deter pigeons, seagulls, starlings, crows, swallows, sparrows and other nuisance birds.
When are bird spikes used?
Bird spikes are commonly installed in the following locations:
- Building ledges
- Signs, beams, and overhangs
- Rooftops
- Window sills
- Statues and monuments
- Gutters and drains
- Patios and decks
- Air conditioning units
- Any flat or protruding surface where birds tend to land or nest
They can be used to prevent bird droppings and nesting materials from accumulating and creating unsanitary conditions. They also help protect building infrastructure by keeping birds from causing corrosion or blockages.
Proper installation of bird spikes
To be effective, bird spikes must be installed properly:
- Measure the surface area to determine how much spike material is required.
- Clean and prepare the installation surface – remove any dirt or debris.
- Use the manufacturer’s recommended adhesive and apply a generous amount.
- Press the base of the spikes firmly into the adhesive and hold for 30 seconds.
- Space parallel rows no more than 2.5 inches apart.
- On ledges, spikes should overhang the edges by 2-4 inches.
- Around pipes or power lines, wrap the spikes tightly leaving no gaps.
- Use end caps on any exposed spike ends for safety.
- Allow adhesive to cure fully before exposing spikes to weather or birds.
Proper spacing and adhesion are key for effectiveness and preventing the spikes from detaching over time.
Who is qualified to install bird spikes?
When installed incorrectly, bird spikes can fail to deter birds or pose safety risks if they detach. Professional installation is recommended in many cases to ensure proper fitting. The following professionals typically have the necessary skills and experience:
Pest control technicians
Pest control companies often provide bird spike installation services. Their technicians are trained on proper measuring, surface prep, adhesive selection and application techniques. They know how to space and position the spikes for maximum effectiveness against different bird species.
Roofing contractors
For roof installations, a qualified roofer is best equipped to safely adhere bird spikes along eaves, vents and other challenging surfaces. They have experience working at heights while following safety protocols.
Handymen
Experienced handymen may also have the necessary skills to properly measure, cut and adhere spikes. Look for ones familiar with basic construction, adhesion and safety principles.
Building maintenance staff
In-house maintenance professionals responsible for a property can be trained to install spikes safely. For large buildings with recurring bird problems, having staff handle regular spike maintenance and replacements can be more economical.
Safety considerations
Bird spikes must be installed with safety in mind, especially in public spaces:
- Use blunt-tip spikes to reduce risk of cuts and abrasions.
- Securely adhere spikes with quality adhesive to prevent detachment.
- Check spikes regularly for wear and replace as needed.
- Install end caps on exposed spike ends.
- Provide sufficient overhead clearance for pedestrians (at least 7 feet).
- Add cautionary signage if needed.
- Repair any damaged sidewalks or landscaping.
Legal requirements
Several legal considerations apply to bird spike installation:
Building codes
Local building codes often govern additions or alterations made to building exteriors. Applying for a building permit may be required prior to spike installation. This ensures the work will be inspected for safety.
Zoning laws
Bird deterrents like spikes may be prohibited in certain designated scenic or historic districts. Zoning laws should be checked.
Condominium rules
For multi-unit properties, the condo corporation’s rules apply. Approval from a condo board may be needed before owners can install exterior spikes.
Public lands
Bird spikes are typically not allowed on government owned public buildings, bridges, signs, etc. Alterations require permission.
DIY installation
For small residential installations like porches or deck railings, DIY installation may be suitable. Some tips for proper DIY spike fitting:
- Select blunt tip spikes for safety.
- Carefully measure and purchase enough spike material to adequately cover surfaces.
- Follow manufacturer’s instructions for approved adhesive types and application technique.
- Ensure the mounting surface is clean and dry first.
- Press spikes very firmly into the adhesive and hold for 30+ seconds.
- Confirm spikes are securely attached after adhesive has cured.
- Monitor spikes regularly and replace any missing or damaged sections.
However, for large commercial installations or challenging locations, hiring a professional is strongly recommended whenever possible.
Conclusion
Bird spikes, when installed properly, provide an effective and humane way to deter birds from unwanted areas. However, professional fitting is advised in many cases to ensure safety and performance. Pest technicians, roofers, and experienced handymen typically have the necessary skills. Building codes, zoning laws, condo rules, and legal permission should also be considered during the planning stages. With some safety precautions, bird spike installation can successfully solve bird problems without harming birds or people.
