How to get rid of bats in attic – Unwanted guests in your attic? Bats can be a nuisance, but fret not! This comprehensive guide will equip you with the knowledge and strategies to effectively get rid of bats in your attic while prioritizing their well-being.

Bats are fascinating creatures, but their presence in your attic can pose health risks and cause damage. Understanding the signs of their presence, employing humane exclusion methods, and implementing preventive measures are crucial for a successful bat removal process.

Identifying the Presence of Bats

How to get rid of bats in attic

Bats are nocturnal creatures that often seek shelter in attics during the day. Identifying their presence is crucial to prevent potential health hazards and structural damage. Here are some telltale signs to look for:

Entry Points

Inspect your attic thoroughly for any potential entry points, such as gaps around vents, chimneys, or soffits. Bats can squeeze through surprisingly small openings, so even a crack or hole the size of a quarter can provide access.

Guano Accumulation

Bat guano, or droppings, is a common indicator of their presence. Look for dark, crumbly deposits in corners, along beams, or on insulation. Guano accumulation can also produce a musty odor, which can be noticeable upon entering the attic.

Other Signs

  • Scratches or bite marks on insulation or wood
  • Noises such as squeaking, fluttering, or scratching at night
  • Oily stains on walls or beams where bats have rubbed their fur

Humane Exclusion Methods: How To Get Rid Of Bats In Attic

Humane exclusion methods are an essential aspect of bat removal, prioritizing the well-being of the bats while effectively deterring them from re-entering the attic. These methods involve non-lethal techniques to encourage bats to leave on their own, without causing them harm.

One-Way Exclusion Devices

One-way exclusion devices are designed to allow bats to exit the attic but prevent them from re-entering. These devices are typically installed over entry points, creating a funnel-like structure that guides bats out of the attic while preventing them from returning.

To effectively implement one-way exclusion devices:

  • Identify all potential entry points for bats.
  • Choose an exclusion device that is appropriate for the size and shape of the entry point.
  • Install the device securely over the entry point, ensuring there are no gaps or holes that bats could use to re-enter.
  • Monitor the device regularly to ensure it is functioning properly and that bats are exiting but not re-entering.

Sealing Entry Points

Sealing entry points is another effective humane exclusion method. By eliminating access to the attic, bats are discouraged from returning. Sealing entry points involves identifying all potential entry points and using appropriate materials to close them off.

To effectively seal entry points:

  • Inspect the attic thoroughly for any cracks, holes, or gaps that bats could use to enter.
  • Use caulk, expanding foam, or other suitable materials to seal all entry points, ensuring there are no gaps or holes left.
  • Pay particular attention to areas around pipes, vents, and chimneys, as these are common entry points for bats.
  • Regularly inspect sealed areas to ensure they remain intact and that bats have not found new entry points.

Chemical Deterrents

Chemical deterrents are substances that emit a strong odor that bats find unpleasant, encouraging them to leave their roost. These deterrents come in various forms, including liquids, granules, and sprays.


  • Effective in repelling bats
  • Can be applied to areas where bats are roosting
  • Relatively inexpensive


  • Can be harmful to humans and pets if not used properly
  • May not be effective for all bat species
  • Can leave a strong odor that may be unpleasant to humans


To safely and effectively apply chemical deterrents, follow these steps:

  1. Identify the areas where bats are roosting.
  2. Choose a chemical deterrent that is appropriate for the type of bats you are dealing with.
  3. Follow the manufacturer’s instructions for application.
  4. Wear protective gear, such as gloves and a mask, when applying the deterrent.
  5. Ventilate the area well after applying the deterrent.
