Which term describes a practice that physically excludes bats from roosts to prevent entry?

• A. Exclusion
• B. Baiting
• C. Trapping
• D. Deterrence

Answer: (A)

Exclusion is a physical method that blocks access to roosts by sealing all entry points after the bats have left, often using one-way exit devices so they can depart but cannot return. Once the roost is clear, the openings are permanently closed. This approach targets the actual access points and is preferred because it removes the problem without harming the bats and prevents future entry. It’s important to time exclusions correctly—usually after the maternity period so pups can fly and before winter—so you don’t trap young or disrupt the colony, and to follow local wildlife regulations. In contrast, baiting relies on attractants or poisons, trapping captures and removes individuals rather than blocking entry, and deterrence aims to discourage use without blocking access, which may not prevent entry.
