Exclusion is the way to solve bat problems by removing access to the building while letting bats leave. The approach starts with a careful inspection to find every point where bats can enter. Then you install one-way exits so the animals can fly out but cannot get back in. After you’re confident the colony has evacuated—usually after pups are old enough to fly—you seal all openings permanently. This targets the issue directly, is humane, and stops ongoing entry, moisture, and contamination problems that roosts can cause. Traps pull individuals out but don’t prevent future entry; they can also stress or harm bats and don’t address the entry points. Repellents and deterrents tend to be unreliable for established roosts and won’t effectively stop a colony from roosting behind walls or in ceilings.
