Scientists might not agree on the causes of the bat die-off, but they do agree on the consequences. Bats are an important predator of mosquitoes; a single brown bat can eat 1,000 or more insects in an hour. They also eat beetles and other insects that damage plant crops. If there arent enough bats, damage will be great from the insects they eat While bats live a long time for their size 一 the little brown bat can live for more than 30 years 一 a female bat has only one baby per year, so bat populations grow slowly. Many bat species in the United States are already protected or endangered.
How can you help? Do not disturb sleeping or nesting bats. If you discover bate that seem to be sick or that are dead, contact your local Fish Wildlife Department with the details. However, be careful not to touch the animals.
