Things You'll Need
Instructions
Remove garbage and other food sources that might attract pigeons from outside the barn. Pigeons are not picky eaters and will scavenge for food almost anywhere. Discourage them by making it difficult to access food around the barn.
Locate any pigeon nests inside the barn. Baby pigeons stay in the nest for up to two months, so be sure the nest is empty and no longer in use. Check rafters, gutters and other sheltered coves where the birds might be tempted to nest. If you discover an empty nest, remove it from the barn.
Set spikes on the edge of the roof and on top of rafters to discourage pigeons from roosting on your barn. Cover any flat area where the birds might be tempted to rest. Placing wire mesh on the roof will make it uncomfortable for the pigeon's feet.
Purchase a plastic owl or other large predatory bird and place it in a prominent place on or near the barn. The fake predator will fool the pigeons and keep them away from the barn as if it were a scarecrow.
