Bats entering homes is a very common occurrence, though not something you would want to happen in your home, Bats will typically cause damage to insulation & drywall. our process of excluding bats from a structure is installing a one way valve allowing the Bats to get out once installed it is important to close all other possible entry points to prevent Bats from getting back into the home, after the close up has been completed we come back in a few weeks to check for activity, remove the valve, and close the valve opening to preventing a re-occurrence of animal entry.
