Another myth associated with pigeon repellent gel is that it is harmful to humans and other animals, if handled carelessly. Sure, ingesting it for instance can make you or your pet feel sick. But it won’t kill you or have any negative long-term effects. Also, the way the gel is sold was designed to be easy to manipulate and use by almost anyone. All you have to do is just glue it to whatever surface the pigeons gather on and you’re done. Also, chances are that your dog won’t climb on top of your roof or your raters to chew on the gel, and your cat will most likely just avoid it after smelling it.
