Bird Spikes, 20 Packs Bird Deterrent, Raccoon for Outdoor Repelling Reptiles, Squirrel Spikes for Fences and Roofs to Keep Birds Away（18.7Feet）

This product exceeded met my expectation, but the installation was ugly - Really Ugly! We had an owl that would land on our outdoor light to eat. This owl pooped all over the outdoor light and made a big mess of the light, wall, and concrete patios. This product worked from day one. The only issue was it was ugly when I finished the installation. Not sure how to install it and not have it be ugly. You ought to come up with contest to award the best installations.

Keeps the puppies out of the flower garden. Easy to fit this to what you need.

While these were great quality and the idea behind them was good and hopeful, they just did not work for us. We have persistent robins relentlessly making nests on our deck roof ledges. I feed the birds in my yard. I love birds. But, the location the robins are attempting to nest in is dangerous. My dog is a beagle mix and VERY much a hunter. There would not be a good outcome if a nest of baby robins was above "his" yard. We fenced in a section of our yard for the dog. I know that baby birds spend a few days on the ground learning to fly. Also these nests are directly above our BBQ grill and table and chairs. The mess they are making building nests is pretty gross actually. Anyway, we installed these across the entire length of the roof ledges. What we've learned is, they are actually assisting the robins in building the nests because the brush and grass and nest material they are finding is sticking to the sharp points and helping it stay on the ledges better. So, this idea totally backfired for us. Instead of deterring the birds, it is more inviting as it is assisting with the nests not blowing off of the ledges. These robins have big plans because the nests they build are HUUUUUGE.

That the item works for intended purpose. It seems to help so far.

We have a bird feeder (we love our birds) that we installed to our pool fence some months ago. Well, it wasn't long before Mr. Squirrel and his clan decided that the birdfeeder was THE place to dine and dash! They destroyed the plastic grommets on the feeder and bird food was spilling everywhere when Mrs., Birdie went to eat!We tried pretty much every item on Amazon to deter the squirrels but not harm them too much and certainly not harm our beloved feathered friends. Nothing worked. Spikes, metal spikes and even cayenne pepper did not work!So, we started thinking like a squirrel...odd, I know, but these are very determined little guys who I believe are mini engineers! First step was to get a new feeder. Then we bought these spikes. We found that the trick is to use all of them to keep the squirrel as far as possible from the feeder. We installed the spikes on top of the wrought iron fence 4 feet in each direction on the top of the fence and used metal spikes underneath that so there was a limited area for them to climb,The plastic spikes are SUPER sharp (ask me how I know) but are a huge deterrent to Mr. Squirrel's sensitive pads on his hands and feet.Now he comes hippity hoppy to the fence as always and then sits and ponders his predicament... he sits and chills out for a while and then just leaves! These cones come with no hardware but, we used 18" black zip ties in the center of each one and that is more than sufficient.... here is a tip... don't secure them in multiple locations so that they are locked in place...Mr. Squirrel hates it when what he is trying to walk on moves... even the slightest bit, so one zip tie will secure the spikes and make them a bit wobbly for a bit of extra protection for you. The top of our fence is very small so these are the ideal size. If you have a larger fence you will just need some more to keep these furry rascals at bay. Highly recommended!

I’m having raccoon problems on my roof. They damaged the roof to the tune of 2 grand. I had these spikes installed. Unfortunately, they haven’t deterred the raccoons, not because they aren’t effective but because raccoons have been assaulting my house for 40 years and have learned to bypass EVERY deterrent I have tried. Over the years, I have learned the names of mama and babies and have had MANY generations just laugh at my attempts to stop them. The spikes look cool, but haven’t stopped these determined monsters!

While I think these helped some, in other cases, the sharp spines acted as a perfect anchor for birds nests that could stand up to any amount of wind.We have a multilevel deck that faces a lake and the birds love to nest above the main beam and between the joists. I chose to do battle with the birds this year, and I am willing to admit defeat,,,,for now. I think it helped to deter birds in some locations, but in other locations, the birds literally wove their nest into the points. My gut tells me that it will work for larger birds (robins, crows, etc), but little birds have such a small weight to them that the points do not hurt them.I will try positioning them a bit differently next year to see if it will work.

Helps keep curious squirrels and rabbits out. Just don’t step on them by mistake. You and the critters will only do it once. Ouch!!
