Are bats afraid of light?

Bats are nocturnal animals that have adapted to a life in darkness, partly to avoid predation during daylight hours from bird of prey species such as sparrowhawks. Therefore the artificial lighting of bat roosts, access points and foraging pathways can be extremely disturbing to bats and should be avoided.

Do bats bite humans while sleeping?
