How to do it:
Seal all entry points with caulk or mesh. Install bat houses away from your goods to provide an alternative roost. Use bright lights or ultrasonic repellents to deter bats from entering storage areas. Regularly inspect and maintain barriers.

Result:
Bats are less likely to enter and damage your goods, as they are deterred by blocked access and unwelcoming environments.

Problem:
This method could fail if all entry points are not properly sealed, or if bats find new ways in. Persistent bats may adapt to deterrents over time.

How to do it:
Hang sachets filled with dried peppermint leaves or spray peppermint oil diluted with water around storage areas. Seal entry points with mesh or caulk. Use bright lights or aluminum foil strips to deter bats.

Result:
Bats are repelled by the strong scent and light, reducing their presence and protecting your goods naturally.

Problem:
If bats are already roosting, they may ignore scents or lights. Entry points missed during sealing can allow bats to return.

How to do it: Identify bat entry points in your property. Wait until bats leave at dusk, then seal all entry points with caulk, mesh, or weatherstripping. Install one-way exclusion devices to allow bats to exit but not re-enter. Remove any bats found inside carefully and release them outdoors.

Result: Bats are prevented from re-entering, reducing the risk of damage to goods and property.

Problem: This method may fail if all entry points are not found and sealed, or if exclusion is attempted during maternity season, trapping young bats inside.

How to do it:
Use biological control by encouraging natural bat predators, such as owls, to frequent your property.

Result:

• Install owl nesting boxes near your house.
• Keep outdoor lights off at night to attract owls.
• Maintain trees and shrubs to provide perching spots for owls.
• Remove food sources that attract bats.

Problem:
This method may fail if local owl populations are low, or if bats find alternative entry points or food sources inside your house.

• Identify bat entry points and seal gaps with caulk or mesh, leaving one exit for bats to leave.
• Mix a solution of water and peppermint oil (10 drops per cup) in a spray bottle.
• Spray the solution around entry points, storage areas, and on goods.
• Reapply every few days, as the scent deters bats.
• Avoid using toxic chemicals to prevent harm to bats and humans.
