Bat Week Has Arrived

Just in time for Halloween, it’s Bat Week! Whether it’s building bat habitat, learning more about different bat species, bat-watching in the late hours of dusk or other ways to brush up on bats, this international celebration (Oct. 24-31 each year) is the perfect time to spotlight this important species. 

Michigan is home to nine species of bats, all of which are insectivores – meaning they eat exclusively insects. During the evening hours, these flying mammals consume many insect pests including mosquitoes, beetles, moths and flies. 

Unfortunately, many bat species are facing challenges. The DNR, along with numerous partners, works to conserve bats and bat habitat because many species are in decline due to habitat loss, diminished food supply and disease.
 
White-nose syndrome is a deadly disease that affects North American bats primarily during their winter hibernation and has devastated many bat species. Infected bats prematurely awaken from hibernation, rapidly deplete their fat reserves and do not survive the winter. Bats with this disease often exhibit unusual behavior, like flying during daylight hours or gathering outside of hibernacula (mines and caves) in cold weather.  

Here are a few things you can do to help bats:

• Plant a bat-friendly garden and minimize the use of insecticides.
• Remove invasive species.
• Install a bat house in a location not frequented by people.
• Do not enter closed mines.
• Follow decontamination guidelines to help reduce the spread of white-nose syndrome.
