ABOUT BATS

  • Bats are among the most misunderstood mammals
  • They rarely attack
  • Most are useful, feeding on insects which are pests to humans and agriculture
  • They become pests when they reside in buildings, scratching and squeaking

CONTROL / PREVENTION

  • Inspect and evaluate the infestation: exit and entry points, structural deficiencies, size of infesting colony
  • Inspect at dusk, when they emerge and during the day to dertermine roosting areas, accessibility to the bats, equipment needed to correct the problem
  • Common entry areas: attic louvers, rooflines, building deterioration
  • Openings 3/8" are sufficient for entry
  • Do not flash a beam of light at suspected openings which may frighten them
  • Plastic bird netting may be tried for bat-proofing
