Overview

• City officials say bats cannot find their way out through tilted windows and advise fully opening the affected room’s windows to allow self‑exit.
• Nabu recommends at night switching off lights, opening windows wide, leaving the room, and giving the animal time to fly out.
• Activity is elevated as juveniles fledge in August and adults intensify feeding to build fat reserves before winter.
• If a bat appears trapped or weak, handle only with gloves or a thick towel, place it in a ventilated box with a cloth and water, and contact a bat rescue center.
• Potsdam has confirmed at least 12 of Germany’s 25 native species in the city, and federal law strictly protects bats and their roosts from harm.
