Bats become a nuisance when they roost in large numbers in human dwellings. The rapid accumulation of guano (bat droppings) is unsanitary, and serves as a fertile breeding ground for a fungal disease called Histoplasmosis, which is transferable to humans who breathe in the fungal spores.
Are bats attracted to light at night time? It is well established that bats are sensitive to light while hunting at night. While some species are attracted to artificial light sources because of the insects nearby, most bat species generally avoid artificial light.
How small of a hole can a bat get through? Most often bats find their way into homes through cracks and crevices in building materials. Their small size makes it easy for bats to tuck themselves into even the smallest of gaps. They can squeeze through holes as small as 6 millimetres or about the size of a dime.

Why are bats important? By eating insects, bats save U.S. agriculture billions of dollars per year in pest control. Some studies have estimated that service to be worth over $3.7 billion per year, and possibly as much as $53 billion. This value does not, however, take into account the volume of insects eaten by bats in forest ecosystems. U.S. Department of the Interior
Where do bats go after exclusion? Exclusion devices should be placed at all entry points and should remain in place for a minimum of seven days. These devices should be removed after all bats have been excluded, and exclusion points should then be sealed. Bat Con
Is it bad to have bats around your house? Bat droppings, called guano, can cause health issues in humans, bats can get into the living area of a home, bat infestations left unchecked can lead to damage to the home as the weight of the guano can affect the attic floor/living quarters ceiling. The guano can also attract insects into the home.
