Bird B GoneSpectrumV Holographic Bird Gel - Bird Repellent Gel - Repels Birds - Protect Edges, Ledges, Rooftops, Etc - UV Protected & Humane - Easy to Install Dishes - 12 Pack

I mainly needed these to deter woodpeckers from the soffits and fascia of my roof. These are expensive, especially if you need a lot of them, but so far they have worked to keep them away, and I’m able to mount them vertically or at a slight negative incline with some silicone adhesive, and the gel doesn’t leak or spill out. While several boxes can add up to a lot of money, it is worth it in the long run to protect the roof and stop paying for repairs.These do not seem to deter pigeons. They will land next to them and step around them, but they don’t like to roost there, so if I space them on ledges about 6 inches apart, that tends to keep them away too, but that is a lot of discs to buy.

Useless against Robins. Put them up yesterday afternoon on heater mounts under a covered outdoor area. By 9AM today the Robins had almost finished building a nest directly on top of one of these. Back to stuffing a large plastic bottle up there. Just wish I had taken a pic of the nest instead of getting rid of it and cleaning the heaters with beach wipes while spewing vulgaritys at the birds that were watching me from 20 ft away first.

They work great , used silicon for a more secure bonding to my window sills, no more birds and no expensive pest extermination bills. So easy to do!!

I have a covered porch and birds like to nest on top of the porch light. Birds disappeared within an hour after I put these up and have not returned. So far they have stayed in place a month, they smell like Citronella and are very sticky.

We've had birds making nests on top of posts on our porch, and were unable to discourage them. I put up metal spikes designed to keep them from making nests, but they made them between the spikes. A few weeks ago I put one of these on top of each post and they appear to be working in keepings birds away. They seemed expensive but are worth it.

The birds have still built nests within a foot of the pucks. You have to buy a lot and line them up in order to keep them out.

I have these beautiful tall trees that wrap around my deck. I love to sit on my deck but the birds would run me off. I do not like birds and i have a bird phobia and we had 100s of birds in those trees. They made my deck nasty with all the poop. I put these around the deck and within 3-5 days most of the birds are gone. I did a double wammy! I also used round silver disc and hung them in the trees as high as i could i even put one in the upstairs window. It works

We were hoping for a solution for a pigeon problem on our balcony but this is not it for us. They are definitely interested in it and curious about it but not deterred in their reign of poop. Plus, the gel completely dissolved in the rain and made a total mess. This may work for some but did not work for us. Unfortunately, cant return since it’s mostly dissolved now.
