Less than one percent of the bat population contracts rabies, which is a much lower rate of incidence than other mammals. Still, you should not handle or disturb bats, especially those that are active and appear sick during daylight hours. All bat bites should be washed immediately with soap and water, and a physician should be consulted.
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.
How long does a bat live? Between 20 and 40 years. Compared to a similar-sized animal like a rat that lives only two or three years, bats live between 20 and 40 years. Researchers theorize this has to do with the ability of bats to fly.
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.
Why are bats important? 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 per year, and possibly as much as $53 billion. This value does not, however, take into account the volume of insects eaten by bats in forest ecosystems. U.S. Department of the Interior
Bats are usually able to exist near human homes without making their presence known. However, with decreasing amounts of habitat available for bats (e.g., trees being cleared), bats may find their way into man-made structures. Bats use existing openings (cracks as small as 1 ¼ inch by 3/8 of an inch) to enter buildings or to roost in attics.
One of the problems that homeowners face after bats have been removed from their Fort Wayne, IN home is attic damage. Bats contaminate insulation with their guano. This buildup of feces will attract insects and damage the insulation.
