Hamilton Wildlife Removal: Are Bats Afraid Of Lights?
Contrary to popular belief, bats are not blind. If they were, then shining lights on them would have no effect one way or another. As nocturnal creatures, bats do not like the light and try to avoid it specifically by seeking out dark places to make roosts, such as unused attics. If bats don't like lights, then it may seem logical to use artificial lights to deter them from your property. In practice, however, this has many more disadvantages than advantages.
