12Pcs Pigeon Spikes Stainless Steel Bird Repeller Set Deterrent Anti Bird Pigeon Squirrel Cats Repellent for Garden Fence Roof

It really works. I used one set for my balcony where so many pigeons land there and do their business. It was so annoying. I fix this and now it is scared to come and land. So I bought another two more boxes to add and fix it there as sometimes they can avoid it at the empty space in front of the balcony. So need to cover up more areas especially their lading area.\nNow it’s so much better. Love this as I did not want to fence it up.. it will disturb my view especially living in a condo.

only got enough pins for 8 of the 12 plastic straps? missing one bag of spikes ?
