Bats

Bats   (Chiroptera)

Bats are nocturnal insectivore mammals. Bats typically eat one-third of their body weight in insects per night. They normally produce one offspring at a time. Bats navigate by echolocation.

Bats can carry a number of diseases which can be transmitted to humans. These include rabies, histoplasmosis,  fleas, mites, and other bat-borne viruses. Some virus are passed through a bat bite or contact or inhalation of guano. Bats will typically attempt to gain entry into a residence attic or crawlspace. The most common way to identify if a bat or bats have entered the residence is when they are leaving for a night of foraging. The second way is bat droppings emit a strong ammonia smell.

Bat exclusion methods are used to remove bats from living areas. They are a protected species due to an infectious bat disease, White Nose syndrome,  and can be removed only during certain seasons. Homeowners may not remove bats between June 1st and August 15th without a Health Exemption Form from the Wisconsin Department of Natural Resources.
