10 Packs Bird Wire Spikes, Bird Repellent Devices Outside, Fence Bird Spikes Strips Deterrent, Pigeon Deterrent for Birds Crow, Cat, Raccoon, Woodpecker Deterrent for Outside to Keep Birds Away, Gone

No pigeons pooping on my front porch any more! Easy to assemble. I used zip-ties (separately purchased, not included with the bird spikes) to attach the spikes to a 2-foot piece of wood - makes it very easy move the spikes around as needed.Keep a good grip on the metal tines when installing on the metal strips, otherwise the springy action will make them fly across the room. It's easy to get the hang of it after you've installed a few.Note: The metal "spikes" aren't sharp, so there is no cruelty to assorted critters and varmints. The spikes are blunt yet still uncomfortable & inconvenient enough to keep the pigeons away.

Assembly required - I thought I was a "tough old bird" and scoffed at someone's suggestion to wear gloves while assembling. Ha! Um yeah, I recommend it now too. They're not for "poke prevention", instead consider you're squeezing together metal prongs to 1/2 inch spacing that really want to be at 4inch spacing, and then squeezing and wiggling and adjusting to poke them in the metal strip holes, and push them through to the other side... about 100 times!That said, ASSEMBLY IS EASY, but my the pads of my fingers were so very sore the next two days, and Im no stranger to working with my hands.After reading several reviews, I opted to use twine to fix these in place, tied to decking cross beams. They are used on top of the crossbeam space under my deck to prevent robins from nesting on the paired 2x12s at my back door again. I wish them luck on finding a new home, just kindly, not at my back door.

With the frames vertical on a pole and the spikes horizontal, our squirrel uses the spikes like ladder rungs to climb into our bird feeder. The spikes are a potential hazard to human eyes if you walked or fell into them. These have kept squirrels off the horizontal top of a heat pump, so I've had partial success. Nicely made, and no rust.

Used these on a fence pole to keep raccoons off roof. Works great. Easy to put together but time consuming. Easy to install.

These are a great value, but putting them all together does a number on your fingertips. Mine hurt for a day after assembling these. Decent material used. THEY WORK AMAZING! I have not had a bird issue since I installed them.

Works perfectly. The only reason for a 4 star instead of a 5 is because there was no option to purchase a smaller amount. I only needed about 10% of what I purchased.

Kept the birds off like I hoped

A total PAIN to assemble. I am positive the devil has a department making these. Right next to the clothes hanger and paper clip sorters!
