OFFO Bird Spikes with Stainless Steel Base, Durable Bird Spikes Arrow Pigeon Spikes Fence Kit for Keeping Small Bird, Crows and Woodpeckers Away, Covers 17 Feet(5.2m)

I bought these metal spikes as a deterrent for my carport support brackets because i had finches and other small birds trying to build nests inside of peak supports and these worked beautifully. I put a 1" by 1" wooden block inside the support arms to raise it up so height wouldn't be a problem and then i placed these spikes inside in the center along with the short plastic ones on each side and now there's no room for the birds to land or build a nest. And what i like about these metal spikes is they are not assembled and every strip measures 13⁹/¹⁶ and 20 criss cross spike slots so you can add as many as you need or as few as you need in whatever space/void you are trying to fill and even cut the strips to a custom size with aviation/tin snips. There's truly a way to solve any problem you just have to apply your mind to figure out a solution and have the willingness to fix the problems at hand. I highly recommend this product cause they will last for years.

Good quality with clear instructions. Well packaged too. I use it to wrap my desk posts to prevent Raccoons clime to my deck, then to my rooftop.

Purchased these to help with doves and finches (I think they're finches), but particularly the doves, that ignore the many available trees and prefer to build their nests around my leaders, soffits, and ledges. Live and let live, but these birds are messy and I refuse to allow a nest on a ledge over my front door, which was just starting when these spikes were delivered. I applied these stakes on the ledge with some Gorilla indoor/outdoor two-sided tape. I then applied the stakes to other popular nesting areas around my property - and fingers crossed - this seems to have done the trick. Two straight days with no birds. I have previously tried plastic spikes and the dummy owl - neither was effective long-term, I am cautiously optimistic that these will be more effective. Use some caution assembling these spikes - between the spikes and the base - it's easy to assemble but if you don't pay attention or accidentally grab them the wrong way they can cut you.

Works great

Installed these bird spikes and birds are gone. Easy to assemble and cost a lot less than the same ones at the brick & mortar stores. I will be buying more as more are needed. Easy to assemble.

Easy to assemble. Had issue with small birds landing outside window and chewing through the window screens. Used double sided tape to attach to brick - have worked! Birds are in the trees/yard and not landing on window sills.

exactly what I was looking for. Too early to say how effective it is, but the design appears that it will work great.

Unfortunately this didn't work for brown birds. Maybe it's because my roof is at angle and they would somehow get between there. But no problems with pigeons. But I took the spikes down and reconstructed the gazebo. That solved the problem.
