I'm looking at the spikes, etc, and wondering if anybody has ever actually used them. The spikes are sold by the foot, and you mount them along ledges, etc, to keep the pigeons from landing or nesting there.
Ebbie, the adhesives would merely be used to hold the spikes in place. Obviously it is easier to use adhesive to put spikes down, but will it hold up through cold winters, hot summers and rain?
Plastic spikes are cheaper, less visible and won't corrode, but do they hold up to sunlight?
Drilling holes and installing fasteners will be more permanent, but what if the limestone cracks? And how much work does anybody want to do at 30, 50, 60 feet in the air?
So I'm just wondering what experiences people have had with these products.
