How Can I Get Rid Of Bats That Are Roosting In My Roof Crawl Space?
Certain species of bats love to live in the attics or roofs of buildings. The most common species to do so are the Little Brown Bat (Myotis lucifugus) and the Big Brown Bat (Eptesicus fuscus) in the more northern parts of the US, and the Mexican Free-Tail Bat (Tadarida brasiliensis) in the southern areas. These bats are known as colonizing bats, because they tend to live in large groups, or colonies. The colony is often called a maternity colony, because it’s almost entirely made up of female bats, for the purpose of birthing and raising young bats. These bats seek out a warm and safe place in which to give birth to and raise the young, and they often choose the attics of buildings to live in. Attics meet all of the criteria necessary for bats: they are high off the ground, often have only small entry holes (bats prefer such areas, because they’re more safe from predators), and they’re warm and dry. Colonizing bats seem to prefer very hot roosting areas. Thus, they often select attics.
