Living with a Bat Colony

There are many reasons why you may decide to maintain your colony of bats rather than try to get rid of them:

  • The roost site may be providing critical habitat for the bats and the chance of losing the colony will be reduced if they can stay where they are.
  • Bats are fascinating and provide a learning environment, especially for children. Some landowners have even installed a viewing chamber to watch the bats without disturbing them.
  • Bats are long-lived (more than 30 years) unlike rodents and usually only have a single pup, making them more vulnerable to population decline.
  • Bats rarely carry rabies and will sicken and die if they contract it, unlike some other animals that are unaffected carriers.
  • Most colonies in buildings are maternity colonies, used year-after-year.
  • Bats consume noxious pests (mosquitoes), agricultural pests and forest pests.
  • Bat guano is an excellent fertilizer.
