Heavy Duty Cat, Bird, Rodent Deterrent Outdoor Anti-Climb Repellent Security Device Spikes - 12 Pack [16.97FT] (1.98 pounds)

I had a serious coyote problem. I have a large coop and free range area that is fenced in with 8 foot fences. One night my coop auto door malfunctioned and a yote got in and kill half my chickens. Then intermittently over the course of the next two months two more yotes hoped over the fence and killed a few more. The worse is the last two did it in the middle of the day. I tried a whole bunch of things, and nothing worked.I was in the brink of either getting rid of the chickens (no way I am going to let the yotes win) or buy a 6 thousand dollar roller system. After researching the roller system I realized that the way they are getting over is jumping up the side of the fence and pulling themselves over. I decided I would give one last shot at keeping them out of the yard with lower expense and bought these spikes because they are ridged and can handle full sun. Imagine my surprise when three days later I found droplets of blood all over the spikes and not a single chicken dead. It's been almost a year now and all my ducks and chickens are thriving.Oh and side note, they spray paint easily, so if brown isn't your color, easy enough to spray paint them something else.

Raccoons have been using the crook of our huge white oak tree as a latrine for years. The crook is at least 15 feet off the ground and the tree is very close to our outdoor eating area. It's difficult to get up there and clean it out, not to mention disgusting and dangerous. We tried spraying the crook with the usual scent deterrents like hot pepper spray and nothing worked.The raccoons prefer to climb the tree from an adjacent fence. We bought two boxes of Defender Spikes and covered the fence top nearest the tree. Then we added a bit of chicken wire as an extra barrier and used heavy duty aluminum foil to create a baffle around the tree trunk. Success! The raccoons have been evicted from the tree and we no longer have to deal with raccoon poop. The aluminum foil baffle was a long shot but it works. The spikes don't seem to be bothering the squirrels but that isn't a problem for us. Great product that solved a really big problem. Edited September 10, 2020. The spikes are still working great but the raccoons have defeated the tinfoil baffle. It kept them out of the tree for a few weeks but they are determined. Next step is to wrap the tree trunk with a metal baffle.

Easy to install and sturdy. I used zip ties to fasten them. They’re not bendable but I was able to curve them enough to suit my needs. I bought this to deter doves from my bird feeders and to stop them from ‘loitering’ above the feeders all day. Doves will sit there and poop over everything below for hours on end. These device has stopped them somewhat but not completely. They are able to gingerly Maneuver their way over them and hang out. If the spikes were 1/2 to an inch higher they would be perfect.

I purchased these to prevent English Sparrows (House Sparrows) from nesting in parts of the aluminum awning over our front porch. It's been a constant battle with them for years pulling trash out of the roof daily. The other spikes were all too long to fit into the space available. These seem to work most of the time. The English Sparrows (House Sparrows) don't like them and although they keep trying they can't seem to get the hang of hopping around with these there. They've started two nests so far and it's a pain to unwind their nesting material from these spike strips but that's only twice this year (June) instead of having to pull stuff down every single day sometimes multiple times a day. On the other hand, with the sparrows not hanging around as much we now are seeing red house finches (with a much nicer song) and gold finches hanging around our yard a lot more. The house finches seem to have the hang of moving around among the spikes, but have not attempted to nest in the porch.

In the first hour, my cats laughed at me by sitting directly on these spikes. It's like they enjoyed it.The fatter of the two noticed that when she sat on them, they moved a little... so then they would just flick them off.The birds on the window just stand on the spikes.They look ominous enough and are well made. They feel sharp to the touch The plastic is thick. Their design is nice and they stack very neatly. But, at least with the animal kingdom in my immediate vicinity (who appear to be masochists), they are ineffective.

We have bump outs framing windows on our stucco house, and birds like to sit on the bumpouts that are close to the porch roof and the eaves because it provides them protection from the elements. This meant our windows had poop streaks down them all the time.I'd seen metal spike deterrent with bird nests in them and we didn't like the idea of having short metal spikes all over our house. So I decided to give these a try. I'm glad I did!A year later, we've not had a single bird dropping on the bump outs I put these on. I'm buying more to put above other windows and along our roof line that overhangs our partially covered deck. There's regularly a line of droppings on deck and these should fix that.All I needed was a little liquid nails all whether adhesive and these were a piece of cake to install. Bonus for us is that they match the color of our trim and you don't even notice the spikes are there.

bought these to rid my second-floor air conditioners of pigeons and raccoons. thought they worked. then my wife came home during tropical storm isaias and said, babe, there's a raccoon on the air conditioner! we went in to the room, looked out the window and my first reaction was the damn thing had fallen onto the spikes, got impaled -- and died. i bang on the window. nope. the damn thing's SLEEPING. like uncle fester from the addams family on a bed of nails. so uncomfortable, in fact, he didn't even want to move. took me five minutes and a flashlight to get him to leave . . . so, here's the deal. these might work on country raccoons. but tough-ass NYC raccoons? not fazed at all by these things . . . what a waste of money . . .
