Pigeon Guard bird spikes / pigeon spikes are of the highest-grade stainless steel with a dense strong plastic base to support and insure once installed a complete pigeon proof area. Applying the adhesive to the wide dense plastic base allows a great support for the stainless steel spikes to stand strong and wide for a very complete coverage. Imperial spikes are able to cover area of 9 inches wide

Installation of bird spikes / pigeon spikes can look easy but leaving a two finger space between each other will allow pigeons to enter and eventually make nest over the pigeon spikes
