What features should you look for as bat entry points?

• A. Loose flashing, vents, shingles, or siding that bats can squeeze through or under
• B. Solid brick walls
• C. Glass windows without frames
• D. Metal fences

Answer: (A)

Bats enter buildings through openings in the exterior envelope, often around the roofline where the structure is most exposed to wear and movement. The best choice highlights loose flashing, vents, shingles, or siding that bats can squeeze through or under. These features create small, hidden gaps that bats can slip through to reach attic spaces or interior voids. Bats don’t rely on solid, intact surfaces like brick walls or glass windows to gain access; those materials act as barriers unless there are actual openings or cracks. By focusing on gaps and protrusions around the roof, vents, and siding, you’re targeting the real pathways bats use to enter structures.
