White Nose Syndrome

White Nose Syndrome (WNS) is the greatest catastrophe to ever hit US bat populations. This poorly understood malady causes a white fungus to grow on the noses and wings of hibernating bats, ultimately causing their death. The condition was first documented in 2006 and then identified in several caves near Albany, New York in 2007.

WNS has spread rapidly across the United States and parts of Canada. The disease has now been found in over 22 states and, as well as in 5 Canadian Provinces, has killed over 7 million bats. The fungus that causes WNS has also been detected in an additional 4 states, without evidence of the disease. In some roosts, 90 to 100 percent of the bats have died from the disease. As WNS spreads to the Midwest, it threatens the federally endangered bats such as the Indiana bat and the gray bat, as well as some of the largest bat populations in the United States.
