Touri 24 Pack Clear Transparent PVC Bird Spike Strips for Outside Fences and Roofs to Keep Birds, Pigeons, Cats, Squirrels, Raccoons Away and Keep Birds from Building Nest

Best squirrel deterent I've purchased! Works better than netting, repellent, owls, etc, and MUCH cheaper! Wish I had tried this before spending over $200 on all the other recommended squirrel deterrent items I've purchased.

Not Effective Against Persistent Wildlife This product didn't solve our squirrel and critter problem. The adhesive tabs provided weren't strong enough to keep the plastic strips securely in place - they kept coming loose despite our efforts. We even tried reinforcing them with Liquid Nails construction adhesive, but that didn't help much. The squirrels quickly adapted to the deterrent, learning to carefully step around the spikes. Even worse, some critters simply chewed through the plastic points to create their own pathways past the barrier. If you're dealing with determined wildlife, you may want to look for a more robust solution. These strips might work for occasional visitors, but persistent animals will find ways around them.

good strong spikes,and a good size to install.ensure surface is clean before using double sided tape. unfortunately, these spikes do not work on 9n large animals.mine was a large seabird with tough webbed feet

They do not work for deterring mice, they walk right over it.

Works well for birds but not as much for squirrels. The squirrels simply arch up and place their feet in between each spike and walk right over them. If there were mini spikes in between the big spikes, then this would work much better They stay put with the double-sided tape. Works for larger birds. I would not purchase again for squirrels.

These are great if you have a ledge or pergola where birds roost, try to make nests or poop on your patio. They are easily installed, just follow the instructions, you can also cut them to size with scissors.

They are really sharp.

I bought this product about a month ago and I installed it covering the top of a support beam on my patio which the birds seemed to love to roost on. One day I noticed a pair of morning doves were building a nest on top of the support beam which prompted me to buy this product. Today I went out onto my patio and looked up at the support beam and a pair of mourning doves are walking all over the top of this product and building a nest. Obviously this product is not sharp enough or spiky enough to keep birds from landing on it because I watched them walk back and forth over the tips of each of the cones. I'm super disappointed that this product had so many positive reviews because it did not work for me at all and the birds don't seem to care it's even there.
