Control Methods

Exclusion

  • Polypropylene netting checkvalves simplify getting bats out.
  • Initiate control before young are born or after they are able to fly. 
  • Quality bat-proofing permanently excludes bats.

Trapping

  • Available, but unnecessarily complicated compared to exclusion and bat-proofing.

Repellents

  • Illumination. 
  • Ultrasonic devices: not effective. 
  • Air drafts/ventilation.

Other Methods

  • Artificial Roosts. 
  • Sanitation and clean-up.
