A spreading plague is wiping out the nationwide bat population.
 
Scientists say a fungus known as White Nose Syndrome has claimed the lives of over 7-million bats. The disease was first identified in New York in 2007 and is killing bat colonies across the Northeast, including in Pennsylvania.
 
Experts say if the bat population continues to decline it could have a significant effect on the environment due to the fact that bats help control the mosquito population and also feast on crop damaging insects.
 
Scientists are continuing to study the disease but say there is no known cure at this point in time.
