Aeibxiy Bird Spikes, 5 Pack Bird Deterrent Spikes for Outdoor, Plastic Bird Spike for Small Bird Cat Squirrel, Pigeon Spikes for Fence Roof and Wall

I've been having birds build a nest on my Pergola in a few spots that are well protected for their nests. However, the mess they create is not worth allowing the birds to nest there. Because of the location where I needed these spikes, I had to use a heavy duty double-sided tape to secure these spikes.They are very easy to take apart for the correct size you may need. However, there are no instructions on how to assemble them. I needed to look at the picture on Amazon's WEB site to understand how to insert the spikes correctly.I would still recommend these.

The spikes are made well, and easy to put together. However I learned today that they don’t work on angled surfaces. Birds always build nests on my dryer vents, so I put these out, and instead they started the nest next to it, and are using it as a perch.But I’m sure they work great if used properly!

I had these mounted on a 4x4 pole to keep squirrels from jumping onto the feeders. The squirrels used these as ladders and went faster up the pole. They are extremely dangerous! I removed them because I was afraid of bumping into them. I will not buy this product again.

It works just as designed and described. Easy to put spikes together and comes with a lot. I had to adhere to cement so it was tricky finding the right material. I used a stone adhesive putty/clay by “gorilla”. It worked!! Very pleased. And highly recommend.

To discourage birds from nesting over a porch.

These spikes are exactly what I needed to keep the birds from building nests in my entrance way. Easy to install and can be easily modified for your needs.

The product worked perfectly.

Fits in small spaces, can easily adjust length. Will do a great job
