By eating insects, bats save U.S. agriculture billions of dollars per year in pest control. Some studies have estimated that service to be worth over 3.7 billion dollars per year, and possibly as much as 53 billion dollars per year.

This value does not, however, take into account the volume of insects eaten by bats in forest ecosystems and the degree to which that benefits industries like lumber. It also doesn’t take into account the critical importance of bats as plant and crop pollinators. So the actual monetary worth of bats is far greater than 3.7 billion dollars per year.

Are bats blind?

No, bats are not blind. Bats have small eyes with very sensitive vision, which helps them see in conditions we might consider pitch black. They don’t have the sharp and colorful vision humans have, but they don’t need that. Think of bat vision as similar to a dark-adapted Mr. Magoo (a cartoon character with very poor vision). Learn more at the USGS North American Bat Monitoring Program (NABat)...

Are bats dangerous?

All healthy bats try to avoid humans by taking flight and are not purposely aggressive. Most bats are about the size of a mouse and use their small teeth and weak jaws to grind up insects. You should avoid handling bats because several species, such as the hoary and big brown bats, have large teeth that can puncture skin if they are handled improperly. Less than one percent of the bat population...

Do vampire bats really exist?

Yes, but not in most of the United States. Of the three species of vampire bats in North America, only a single specimen has been recorded for the United States in extreme southwest Texas. Vampire bats do not suck blood--they make a small incision with their sharp front teeth and lap up the blood with their tongue. Vampire bats in Mexico and South America feed on the blood of livestock such as...

Where do bats live?

Bats can be found in almost all parts of the world and in most regions of the United States. In general, bats seek out a variety of daytime retreats such as caves, rock crevices, old buildings, bridges, mines, and trees. Different species require different roost sites. Some species, such as the Mexican free-tailed and gray bats live in large colonies in caves. A few solitary species, such as the...

Assessing the risks posed by SARS-CoV-2 in and via North American bats — Decision framing and rapid risk assessment

The novel β-coronavirus, SARS-CoV-2, may pose a threat to North American bat populations if bats are exposed to the virus through interaction with humans, if the virus can subsequently infect bats and be transmitted among them, and if the virus causes morbidity or mortality in bats. Further, if SARS-CoV-2 became established in bat populations, it could possibly serve as a source for new infection

U.S. Geological Survey response to white-nose syndrome in bats

OverviewSince its discovery in 2007, the fungal disease known as white-nose syndrome (WNS) has killed more than six million bats. Ten of 47 bat species have been affected by WNS across 32 States and 5 Canadian Provinces. The cold-growing fungus (Pseudogymnoascus destructans) that causes WNS infects skin covering the muzzle, ears, and wings of hibernating bats. The fungus erodes deep into the vital

White-nose syndrome in North American bats - U.S. Geological Survey updates

White-nose syndrome is a devastating wildlife disease that has killed millions of hibernating bats. This disease first appeared in New York during 2007 and has continued to spread at an alarming rate from the northeastern to the central United States and throughout eastern Canada. The disease is named for the fungus Pseudogymnoascus destructans, which often appears white when it infects the skin o
