To discourage barn swallows from nesting, remove existing nests before they are used in the breeding season, as this is often illegal once eggs are laid. Install physical barriers like netting or spikes on ledges and eaves where they typically build nests. Additionally, creating an uninviting environment by using decoys or sound deterrents can help. Keep in mind that barn swallows are protected under the Migratory Bird Treaty Act, so ensure compliance with local laws before taking action.
