Bird Spikes, 20 Pack Bird Deterrent Spikes for Small Squirrel Cat Woodpecker Crow and Raccoon, Pigeon Spikes for Outside Fences Walls and Roofs to Keep Birds Away

I used them to keep the squirrels away from my AC because they were chewing on the wires.

These spikes kept the squirrels from jumping on the porch banister where they would then jump on the hanging bird feeder. We just placed them on the banister. If eventually they fall off, we'll secure them, but so far this works. Good product.

Spikes are very sharp, in fact, you should wear thicker leather gloves to handle. Unfortunately, within 30 minutes of installation, two smaller birds did not have any issues sitting on the spikes. Probably better suited for larger critters.

I had high hopes that these spikes would deter the squirrels from leaping from the fence and deck to the bird feeder. They did…for a while until I spotted one standing on the spikes. Ultimately, I guess they do work because the squirrels got together and hatched a plan to get around them. They are definitely sharp, as my husband can attest to as he got poked several times as he installed them.

Simply did not work. Had to buy Velcro to adhere these - all work and expense for naught as the squirrels chewed it out on day 2!

They just dug around them or pushed them aside! I think they actually made the squirrel damage worse!

We are satisfied with this product and vendor.

Honestly, I am happy that I bought these. I have a PVC fence and my neighbors tenants decided that she wants to go on a frenzy and start to feed stray cats, and even take them into her house because we complain so much. They started to use my PVC fence as a daily crossing and the odors in my backyard were completely unbearable. Now that they are up, I don’t have any cats in my backyard. I definitely think that this product works.
