Defender™ Bird Spikes and Pigeon Spikes are the leading humane product to get rid of birds from your property. These bird control spikes are quick and easy to install and are available as plastic pigeon spikes and stainless steel bird spikes.

This humane bird deterrent gets birds off ledges fast and effectively without harming them. The protruding pins make it uncomfortable for the bird to land without injuring or hurting it, they will simply move on to an easier roosting site.

The Defender Bird Spike range are suitable for lighter bird problems – using a Defender™ 4 Narrow Steel or Plastic Spike or if you have a heavy infestation – just use a Defender™ 8 Wide Stainless Steel Bird Spike!

We’re often asked about the skill level required to install these pigeon repellent spikes. I’d say that if you can use a ladder to clean a bedroom window, then installing these pigeon repellents should be very easy.

If you don’t feel confident installing this pigeon repellent, why not ask a friend, neighbor, handyman, or a professional window cleaner to give you a hand? Show them the installation guide, and provide them with the spikes. Installed spikes will repel pigeons for many years.

We suggest you pay them $2 or $3 per foot to install the spikes.
Maybe a little less if they’re a friend; maybe a little more if there’s a lot of cleaning to do!

A guide on how to install Defender™ Bird and Pigeon Spikes


1. Defender™ Bird Spikes are humane and do not hurt birds or pigeons Spikes do not hurt birds – they simply prevent pigeons from landing. They’re approved by almost EVERY humane group in the world, including The Humane Society of the United States and PICAS.
2. Clean the area before installing Defender™ Bird & Pigeon Spikes All areas that you intend to stick the spikes onto should be cleared, ensuring that they’re clean, dry, and free from pigeon droppings.
3. Squeeze Defender™ Bird Spike fixing silicone on to the base of the spike Squeeze the pigeon spike fixing silicone generously onto the base of the spike (about as thick as your pinky; thicker if the surface of the ledge is uneven).
4. Stick the base of the Defender™ Bird Spike level with the edge of ledge Stick the base of the spike level with the edge of the pipe or ledge, so that there’s a slight overhang of the spike pins. Press the base down firmly so that the glue oozes out through the little holes.
5. Make sure that there is no gap behind the Defender™ Pigeon Spikes If the gap behind the first spike is greater than 2 ½ inches, pigeons will get in behind them. It will therefore be necessary to put another row of spikes into this space to block it.
6. Very wide ledges may require 3 or more rows Defender™ Pigeon Spikes For very wide ledges, 3 or more rows of spikes will be necessary. Note: make sure the gap between rows is no greater than 2 ½ inches.
7. Grooves along the base of the spike enable them to snap into segments to fit small gaps. Grooves along the base of the spike enable them to snap into segments to fit small gaps.
8. Simply putting a spike in front of a hole will not stop the pigeon Very important: spikes will stop pigeons from sitting on a ledge; however, if there is a hole in the eaves, or a cavity in the house’s exterior behind the spikes, pigeons will invariably force their way past the spikes in an effort to get into that hole. Simply putting a spike in front of a hole will not stop the pigeon. Every effort should be made to block the access to this hole or space. You might be able to seal that hole with wire mesh, for example. Please note before blocking the hole you should ensure that there are no pigeons that may be trapped. If you do discover any pigeons please contact your local PICAS office at the following email address for assistance:
9. Spike all possible landing sites with Defender™ Bird and Pigeon Spikes. Every effort should be made to spike all possible landing sites. Pigeons can land on even the smallest piece of ledge or pipe. Snap spikes into pieces to finish off rows or spike small pipes, etc.
10. Warn contactors not to damage the spikes while working. All aWindow cleaners, contractors on ladders, scaffolders, painters, and decorators have a habit of breaking the spikes. Warn them not to damage the spikes while working. If a spike is damaged, replace it as soon as possible.

Important Health and Safety when installing Bird Spikes

Pigeon droppings could affect your health. Wear suitable protective clothing: a dust mask, gloves, overalls, etc. If you intend to use ladders to access the area requiring treatment, only do so if you’re sure it’s stable, and always make sure you have a second person with you to ‘foot’ (hold) the bottom of the ladder securely.

Before you start work, assess the job to make sure you can do it safely without hurting yourself or others. If you have any doubts at all, why not get a quote from someone who can do the job safely.

If you don’t feel confident about doing the job, please send your unused spikes back for a full refund—no questions asked. Better safe than sorry!
