One bat can eat between 600 and 1,000 mosquitoes and other insect pests in just one hour. Bats in other parts of the world feed on a variety of items in addition to insects. Many species feed primarily on fruit, while several types feed on nectar and pollen. Fruit bats perform an extremely important function as seed dispersers. Nectar-eating bats are important pollinators.
Many plant species depend almost entirely on bats for pollination.
Of the 45 species of bats found in the continental United States, six are listed as endangered. In addition, rabid bats are seldom aggressive. Fewer than 40 people in the United States are known to have contracted rabies from bats during the past 40 years. Bats get tangled in people's hair. Although bats may occasionally fly very close to someone's face while catching insects, they do not get stuck in people's hair.
