Prevent Bats from Roosting on Your Porch

To prevent bats from roosting on your porch, seal any entry points larger than 3/8 inch. Install bright lights, as bats prefer darkness. Consider using bat-repellent plants or commercially available repellents. Exclusion is most effective when done outside of birthing season (typically spring and summer).

Understanding Bat Behavior

• Bats seek sheltered, dark spaces for roosting.
• Porches offer ideal conditions if access is available.
• Bats are protected in many areas; check local regulations.

Sealing Entry Points

1. Inspect the porch for gaps and cracks.
2. Caulk small openings around siding, windows, and doors.
3. Use steel wool or copper mesh to fill larger holes - bats cannot chew through these materials.
4. Ensure screens are in good repair.

Deterrents

• Bright Lights: Bats prefer dark roosting areas.
• Bat-Repellent Plants: Mint, eucalyptus, and citronella may deter bats.
• Commercial Repellents: Follow product instructions carefully.

Important Considerations

• Never attempt to handle bats directly.
• Exclusion should be done outside of birthing season to avoid trapping young bats.
• If you have a large bat colony, consult with a wildlife professional.
