Bird-X Extra Wide 8-inch Stainless Steel Bird Spikes - Metal Roof Guard, Pigeon and Bat Deterrent, Animal and Pest Control Supplies, Covers 10 Feet

Si funciono

They work! Easy to install, came in perfect shape.

Awesome product, sturdy, strangely beautiful, and quite effective on mammals. Bought the first set to interrupt a fencetop raccoon highway running through our yard (and our neighbors' yards etc). Wasn't sure if it would work but I was desperate - the critters repeatedly managed to figure out how to outsmart our coop, and ate all of our pet chickens one by one. I set two strips of spikes on the fencetop, side by side with overlapping spikes so there was no way little feet could avoid them, in a location away from bushes/other places that a critter could use to climb around them. The spikes are long enough that a raccoon would get poked on its belly trying to walk over them, but the assemblage is not long enough to keep birds out (we like the birds and have no problem with them). I haven't seen the raccoons yet so I don't know if they are working for those guys, but I am thrilled to report this one set of four strips have been a great deterrent for 1) a neighborhood cat bent on ripping holes in mine, and 2) the zillion squirrels that ferry parasites directly to our pet bunnies. Regarding #2, I saw a squirrel skirt the spikes by hanging from the side of the fence and scooting around, so I installed another set of overlapping spikes along the sides of the fence. That seems to have done the trick...I haven't seen a single squirrel in the yard since then! I bought two more sets to install on the other parts of the fence, and am about to attempt a third set intended to deter black rats from eating the fruit from trees overhanging the fence. I'm going to try overlapping 4 strips to make a maze that hopefully won't be worth it to the rats. I'll report back in a couple of months.

Oh, there are times that you get something and you get the evil grin on your face...this is one of those times. We have had Robins and Doves nesting under our deck for several years and unless I take down the nests daily (and at least twice a day for the Robins) the next thing I know we have baby birds on the way. Interestingly we have plenty of trees 30' away and the deck is their preferred place. The problem is the deck is one story up and they roost in the main beam and then make a mess of our patio below. And then there is the problem that the baby birds cannot fly well and for whatever reason they decide it is a good time to try when we have our dogs out in the yard for that 15-minute window... never a good ending for the birds. Need to do something to get them out from under there.Finally decided to look for the bird spikes to keep them from coming back as the last two I had to be vigilant every day to get rid of the nests they where building.... they then went out in the yard and built them in the trees....imagine that happening!We have 2x8's that are attached to a 6x6 and are about 1.5" apart so I wanted something to span the gap, I ordered the extra wide. It worked out perfect as I didn't even have to attach them to the beams--- they sit between the two 2x8's and stick up about 75% of their height.The end result is that it humanely keeps the birds from making nests and unless you stare at the under side of the deck.... you do not notice the spikes. Installation was awesome as I used a simple pair of side cutters to cut them to length and after installing 50' worth in under 30-minutes, I had only two or three 1-spike wide pieces left over as trash, so definitely an efficient length to work with.Recommend? Absolutely. Am I positive it will keep them away? After poking myself once when I knocked one off the ladder and started to grab it--- I can see why it will keep them away!

I have a black phoebe who makes his living eating the flies attracted to my compost hole. It likes to land on top of my tomato cage thing and crap all over the plant under. So I attached 2 pieces around the upper ring. They flex up and down, but not side to side so, I had to put them on sideways, so I'm taking away one star.It did serve its purpose to keep the bird off the upper ring, but he foiled me and simply lands on the next ring down and continues to crap on my tomato plant.
