ohlela 24 Pack Bird Spikes for Outside to Keep Birds Away - 26.5ft Balcony Pigeon Deterrent, Bird Deterrents for Outside Patio, Bird Spikes for Pigeons and Other Small Birds, Crows, Woodpeckers

This worked!Easy set-up (used a stapler gun to hold them in place) on wood rafters under an elevated deck.No more nests. :)

I covered the entire area of the top of my window air conditioning unit with this product and the birds still roost there. Not helpful at all.

This item works no more birds roasting here

I got them for stray cats and they do keep them away some but a couple cats walk over them still. You can tell it may hurt but hasn't really stopped them. But they are exactly as advertised

After assembling a wooden patio structure this spring, we immediately had birds building nests in the rafters. The answer was spikes to deter further nest building. These are clear vacuum-formed plastic strips, conveniently supplied in 1 foot sections. The kit had enough spike strips to treat all surfaces, yet remain nearly invisible.

perfect for the arches above my entry gates. Easy to cut with scissors to get exact size fit.

Pigeons still walk over the spikes. Does not stop pigeons from perching on ledges.

Great concept but... they are now sitting on top of the spikes and decided to sit on the window as well. Ayiyi.
