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.

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.

There are a wide variety of bat species in the US, though it’s usually the colonizing bat types that cause problems in buildings and require bat removal services.

Bats are usually able to exist near human homes without making their presence known. However, with decreasing amounts of habitat available for bats (e.g., trees being cleared), bats may find their way into man-made structures. Bats use existing openings (cracks as small as 1 ¼ inch by 3/8 of an inch) to enter buildings or to roost in attics.

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

What time of day are bats most active? Bats are the most active at night between the hours of dusk to dawn. As night approaches, bats begin to increase their activity. They will start flying around their cave and then leave in search of food and water. Bats will typically feed for about an hour or two, rest for a bit, then feed again before daybreak.
