Defender 4™ Plastic Pigeon SpikesThe Defender 4™ Pigeon Spikes Plastic is our entry level pigeon spike that is made from super tough polycarbonate. It is fully UV stabilised which protects it from the sun, wind and rain.

It has been designed to protect very narrow ledges or to be used to protect the leading edge of a much wider surface.

Defender 4™ - used to protect ledges that have a depth of up to 4 inches (100mm)The Defender 4™ Pigeon Spikes Plastic should be used to protect ledges that have a depth of up to 4 inches (100mm). Each strip has an overall length of just over 13” (337mm).

Prepare all areas to be clean, dry and free from droppings1. All areas should be prepared ensuring they are clean, dry and free from bird droppings. It is important to look up; it may be that the source of the mess is actually from ledges or pipes higher up on the building. If this is the case you will need to spike these as well. If this is not done, then droppings, twigs etc. may fall down onto the pigeon spikes below rendering them less effective.

Use pigeon spike fixing silicone2. Squeeze pigeon spike fixing silicone generously onto the base of the spike, about (10mm) the size of your finger; thicker if the ledge is uneven.

Stick the pigeon spikes on the ledge3. Stick the first row of pigeon spikes towards the front of the ledge, so that the spikes fully protect the leading edge. Press down firmly so the glue oozes out through the little holes. If the gap behind the 1st row is greater than 2 inches (5cm) pigeons may get in behind. It is therefore necessary to install another row of spikes into this space to block it. For very wide ledges 3 or more rows of pigeon spikes may be required remembering to leave no more than 2 inches (5cm) between rows.

Snap spikes into pieces to finish off rows4. Every effort should be made to spike all possible landing sites that are 2 inches (5cm) or greater. Snap spikes into pieces to finish off rows or spike small areas. Spikes can be easily snapped using your fingers.

Block the access to any hole or space5. Very important: Pigeon spikes will stop pigeons from sitting on a ledge; however if there is a hole in the eaves or a cavity in the exterior wall 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 or expanding foam.

Please note: before blocking the hole you should ensure that pigeons have not become trapped in the recess. If you do discover any pigeon squabs or dependent birds please contact your local wildlife rehabilitator which can be found here.

Fix the base of the bird spikes directly onto any raised parts of the ledge6. Always make sure that the base of the bird spikes are fixed directly onto the top of any parts of the ledge that may be raised slightly higher than the rest of the ledge. If this is not done then pigeons will overcome any spikes on lower parts by standing on the raised section. Spike the highest part of the ledge first then move on to spike the lower sections afterwards.

Replace damaged spikes before pigeons move in7. Window cleaners, contractors on ladders, scaffolders, painters etc. have a habit of damaging pigeon spikes. Warn them to be careful whilst working. A slightly damaged spike is likely to provide an ideal roosting or nesting spot for a pigeon. Any damaged spikes should be replaced before the pigeons move in.

Take Health & Safety Precautions8. Before starting the job, assess the work to make sure that you can do it safely and without hurting yourself or others. If you have any doubts at all then please contact us or return the spikes for a full refund – no questions asked. Wear suitable protective clothing, dust mask, gloves, overalls etc.
