Zipcase 36-Pack Clear Transparent PVC Bird Spikes-Advanced Dual-Length Spikes for Narrow Landing Gaps and Precision Deterrence,Effectively Guarding Against Birds,Pigeons,Cats,Squirrels,and Raccoons.

Ordered it to keep raccoons and other animals away from my yard and it works really well. Easy to install , I basically had double the quantity because my fence is narrow and I had to cut in two pieces. Cheap and effective.

Odd thing but I’m hoping these will help cut down on critters in my raised garden. Will post more later

Sadly, I had high expectations for this, but after setting them all up the squirrels actually used them as a ladder, and I think it helped them reach the birdfeeders. They also were able to chew the plastic and wear it down. In one week, it was useless. I think I need metal spikes. UPDATE - the seller offered a refund, and this is excellent customer service! This may not have worked for me but others have had success.

Easy to install. The material seems pretty good. So far no cats have jumped over the fence.Pretty effective. Really pleased with the design. Fits on the fence good. I didn't use the adhesive due to the shape of my fence. I used some weather proof adhesive. Not coming off for a long time. Will buy again when the time comes.

The birds just ignore this so it's not very effective. Bought 2 packs but returned 1.

Make sure you cover the entire area.

They work great

We had birds pecking at our new windows fail, but once we installed these, they gradually went away. It’s nice to be able to sleep until the alarm goes off, and not have to clean bird poo off my window ledges daily! Would highly recommend!
