The Defender 4™ Narrow Stainless Steel Bird Spike was created to prevent pigeons from settling on smaller ledges. It has a super tough UV stabilised polycarbonate base with stainless steel wires protruding at various angles. This bird spike works just as well as the all plastic spikes that we also sell but is slightly less visible.

The Defender™ 4 Bird Stainless Steel Bird Spikes 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).

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 bird spikes below rendering them less effective.

Squeeze Defender™ Bird Spike Fixing Silicone generously onto the base of the spike - about (10 mm) the size of your finger. Thicker if the ledge is uneven.

Stick the first row of bird 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 as small a gap as possible between the tops of the pins of adjacent rows.

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.

Very important: Bird 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 the 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.

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.

Window cleaners, contractors on ladders, scaffolders, painters etc. have a habit of damaging bird 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.
