One way to control pigeons is to catch them in traps. The traps should be put next to their places of roosting or feeding. Pigeon traps can either be homemade or bought, and come in various sizes. If one is interested in capturing a lot of pigeons, a bigger trap is obviously better. Big traps, however, can be awkward on top of buildings; therefore, it may make more sense to use a few smaller traps in these places.
The most common pigeon trap size is actually quite large, measuring eight feet long and four feet wide and tall. A trap that is less conspicuous has two sections: feeding, which measures 36-by-24-by-8 inches, and holding, which measures 36-by-36-by-8 inches.
Once pigeons are caught within the traps, discarding of the pigeons should be humane and speedy. Local animal shelters or the humane society can provide information on appropriate disposal of the birds. It is not recommended to release pigeons, even if it’s many miles away, as the pigeons will likely come back to the same area or appear as pests in other areas.
To ensure likely success in trapping, it’s a good idea to put the traps by water sources during the summertime (for example, near cooling condensers on roofs in urban areas.) The traps can also be pre-baited for a few days before starting the trapping. To do this, put corn or milo around the outside of the traps. After three to four days, move the baits inside the trap. (In the low-profile trap, the bait can be set in both sections.) Four or five pigeons should be left inside the trap to serve as decoys.
Traps should be checked on every other day, and a fresh supply of food and water must always be available to the birds who act as decoys. If pigeons aren’t coming in, try leaving the trap open for a couple of days and then closing it for four to five days. If you’re not having much success, try relocating the trap.
