Idaho bats provide over $300 million in annual pest control

BOISE, Idaho. Bats contribute more than $313 million annually to Idaho's agricultural industry by consuming insect pests that damage crops, according to state wildlife officials.

The economic value comes from natural pest control. Rita Dixon, the state wildlife action plan coordinator for Idaho Fish and Game, stated that the animals feed on insects that would otherwise harm local produce. The U.S. Geological Survey estimates that bats save farmers across the United States over three billion dollars each year through this biological service.

Local homeowners also benefit from the presence of these mammals. Sierra Laverty, an entomologist with the University of Idaho, noted that specific local species prey on armyworms. These insects caused widespread damage in Treasure Valley yards during the summer. Laverty identified the big brown bat and little brown bat as primary predators of fall and true armyworms.

Idaho is home to 14 different bat species. Dixon said none of these native species feed on blood. She added that bats generally prefer to stay away from people and do not initiate attacks despite common misconceptions.

The state observes Bat Week from October 24 through October 31 to recognize the benefits these animals provide. Dixon emphasized their utility, noting that while humans sleep, the bats are active in controlling pest populations. She described them as a huge help to the ecosystem.

White-nose syndrome, a deadly fungal disease, poses a major threat to bat populations. Dixon reported that some areas in the Northeast have experienced population declines of 90 percent to 100 percent. The loss of bats reduces the availability of natural pest control for agriculture and residential areas.

Bats are classified as a protected non-game species in Idaho, making them illegal to hunt. Residents who find a bat on their property should contact Idaho Fish and Game at 208-334-3700 for direction on safe relocation.
