There are several chemical repellents that can be easily applied to roosting areas. These are usually a tactile repellent or sticky substance that is spread on the roosting area which has a tacky surface the birds don't like. These are available under a number of trade names and they can be obtained through many garden supplies or feed stores.

Pigeons readily enter and are easy to trap, especially on roof tops or ledges where they congregate. There are a number of funnel and bob-type traps on the market. These traps can be purchased through hardware, garden supply or feed stores. These types of traps catch pigeons alive by having a door that lets the pigeons easily enter the trap but not exit. For trap design and construction see Prevention and Control of Wildlife Damage on-line at http://icwdm.org/. If the traps are kept baited, more and more pigeons will continue to enter the traps and you will commonly catch many birds at one time. Continue the trapping until you have eliminated all of the pigeons in the area.
