Getting bats out of a barn can be done safely and humanely by following these steps:

1. Wait for the Right Time:
   • Bats are most active during the early evening and night when they leave the roost to feed. It’s essential to wait until dusk or just before sunset to start the eviction process.
2. Inspect the Barn:
   • Before taking any action, inspect the barn to identify the entry and exit points that the bats are using. Look for gaps, cracks, or openings in the structure where they may be entering.
3. Locate Alternative Roosting Sites:
   • Bats typically have a preferred roosting site. To encourage them to leave the barn, provide alternative roosting options nearby, such as bat houses. Make sure these are installed before the eviction process.
4. Seal Entry Points (Except One):
   • During the daytime, when bats are resting, seal off all the entry and exit points in the barn except for one. This is a one-way exit that allows bats to leave but not re-enter. You can use materials like mesh or netting to create a temporary barrier.
5. Install a One-Way Bat Valve:
   • Attach a one-way bat valve or cone over the remaining exit point. These devices allow bats to exit the barn but prevent them from returning. Ensure that the valve is securely attached.
6. Wait for Bats to Leave:
   • Bats will leave the barn to feed at night but won’t be able to re-enter due to the one-way valve. Give them a few nights to exit.
7. Monitor the Process:
   • Keep an eye on the barn during the evenings to ensure that bats are leaving and not trying to re-enter through sealed points.
8. Seal the Last Entry Point:
   • Once you’re confident that all the bats have left the barn, seal the last entry point using appropriate materials like mesh or wood. Be thorough in your sealing to prevent future re-entry.
9. Clean the Barn:
   • After removing the bats, clean the barn to remove guano (bat droppings) and disinfect the area. Wear appropriate protective gear, such as gloves and a mask, when cleaning.
10. Install Bat Houses:
    • To provide a new roosting option for bats, install bat houses on the exterior of your property. These should be placed in locations with adequate sun exposure and at least 10-15 feet off the ground.
11. Maintain Bat Exclusion:
    • Regularly inspect the barn for new openings or gaps that bats could use for re-entry. Promptly seal any potential entry points to prevent bats from returning.

It’s essential to handle bats humanely and safely during the eviction process. Never attempt to harm or kill bats, as they are valuable for controlling insect populations. If you are unsure about how to handle a bat infestation, consider contacting a professional wildlife removal service or a local conservation agency for assistance. They can provide guidance and ensure that the process is conducted legally and ethically.
