Nine species of bats are known to occur in
Michigan. The two most common species are the big brown bat and
bat. These two species are also the most likely to contact humans because they
readily use human structures for nursery and wintering areas. Michigan also has
two rare species, the eastern pipestrelle (listed as special concern) and the
Indiana bat (federally endangered). Because of the areas these bats inhabit,
neither is likely to be associated with rabies transmission to humans.
Though there are not good quantitative estimates of bat populations, the
proportion of the bat population that is positive for rabies is estimated to be
less than 1%.
