Bird Spikes 30 Packs Outdoor Cat and Bird Deterrent Spikes, Defender Spikes - Keep Pigeon, Cat & More Birds Away from Fences and Roof, Anti Theft Climb Strips (2023 Upgraded | 42.3 feet)

The media could not be loaded. This is an excellent product. When you open the box, it looks like it will take forever . It does not. The product comes in strips nestled together and you simply pull up on a strip to loosen it from the others. Each strip can also be broken into smaller parts, and it comes with all of the tiedowns necessary to secure each piece to a railing. It is so easy to install.The spikes are very sharp. I got this product to try to deter a large insistent robin landing repeatedly on my railing to attack my windows, and of course, leaving excrement all over the place. These spikes have dissuaded him from most places, but I saw him just yesterday alighting on top of one of the spikes, so I put some streamers out as well that I bought on this platform. With both, he has not been back on the rail since. I still saw him tucked in a window area and I’m going to put a strip there as well with some gorilla tape double sided tabs on the front and back.In some of the more vulnerable spots, I also use another set of spikes that are wire spikes. But this product is really excellent for starters.These are excellent hard plastic. Nice quality and they should be durable we will see. I’m going to attach some pictures so you can see the set up.On the video with the staircase, you can just barely see the spikes up on top where I’ve also hung the streamers.

I bought these spikes in July 2023 to install on my balcony rail. Birds liked to perch on the rail and do their business, which landed on the cool deck below by the pool. Since installing the spikes, they have been close to 100 percent effective. I secured them to the rail with black zip ties, which based on my research should have survived the Arizona sun better than white zip ties. However, within a few months of installing the spikes the zip ties became brittle, prompting me to go to "Plan B." Plan B was purchasing "Shintop Reusable Garden Plant Twist Tie 2.8mm, 2PCS 65Feet Heavy Duty Soft Wire Tie for Tomato Plants, Climbing Roses and Vines Organizing (Black)" on Amazon and replacing the zip ties with this wire. Truth be told, I haven't yet switched out the zip ties with the wire, but when I do, I'll update this review. 😃

I liked the ability to multiple stack the strips. I had an animal using a flower bed as a toilet. These strips blocked that area, so I no longer have the cleanup issue near the wall I'll the house.

I had some openings where my skirting isn’t flush to the ground due to some roots. These have a little flexibility so I was able to use really long screws to go over the roots and anchor them to the ground. They haven’t budged and animals haven’t tried to scoot them up.

If you want a severely injured an animal that’s more dangerous than a bear trap by this if you want to get rid of the animal, you have to cut the chips off because of so sharp. It’s like metal spikes. It’s a stupid pathetic weapon. They’re doing to get rid of regular animals out of your yard.

We have struggled with our cat urinating in places where they should not. After setting these strips of spikes down, it has stopped. The strips are easy to instal, store easy when not in use.

Not sure if it is the Arizona heat, but these did not last 1 summer.

Don’t bother with these for cats. Zero effectiveness. Cats literally will sleep on them.
