How to keep pigeons from the roof of my house?

We had a serious bird problem. They were under our gazebo and every time we walked out there, 5-8 birds would fly out of their nests. Once removing the nests, use a Bird B gone gel in all areas where they were coming and going. Wherever they can sit near their nests, put this gel. It is super sticky and gets on their wings which they hate. They will leave!! It was the only thing that worked for us. We tried everything, an owl figure, spikes....nothing worked except this stuff. Good luck!!! https://www.amazon.com/Bird-Gone-MMTBG-Transparent-10-Ounce/dp/B010CSTTS8/ref=sr_1_1_sspa?crid=YATMB80N1SGV&keywords=bird+b+gone&qid=1556122204&s=gateway&sprefix=bird+b+gone%2Caps%2C149&sr=8-1-spons&psc=1&smid=ATZ61JQHZC6XB

Just to let you know there is some conversation/controversy over this product. I don't believe it hurts the birds because we were told it doesn't and I never witnessed any birds get hurt or any dead birds when we used this stuff. We didn't overload the product to the point that the birds couldn't fly again. It was a light use and I could see the birds get it on their feet when perched and they would leave the area IN FLIGHT!. We waited till all the babies were gone from the nest before using this product, but even after the babies were out of the nest, the adult birds continued to come back to the same nests. That is when we used this product. You might want to do more research if you are concerned that it would hurt the birds. This was just our experience. Nothing else seemed to work because we were dealing with sparrows. As for pigeons, maybe the spikes would be better to try first. The spikes they offer as a product are definitely for bigger birds. Good luck!

We had a bird problem. It seemed they were only nesting when we weren't there and making noise with movement. My husband put a boombox in the attic on high volume and when we left, he would turn it on. We have 85 acres so no neighbors to complain but it did work.

Several business around here use this type of owl decoy. Seems to work.

Guy an owl decoy and place it up there. They are afraid of owls and will most likely stay away.
