Bats are cute little creatures that weigh about
half-an-ounce, but eat lots and lots of mosquitoes – and they’ll soon be
returning from Central America looking for homes. The bats in the north Texas area
are mostly Mexican free-tail Bats (like those in the Congress Ave. Bridge in
Austin). They cleanse the nights of tons of pesky bugs and avoid humans as much
as possible.
An average bat will eat up to 5000 mosquitoes and other
flying pests every night. In simpler terms, that’s like a 60 lb. child eating
126 peanut butter & jelly sandwiches a day. A colony of bats is a safe and
cheap replacement for a lot of pesticide spraying! But those scary, misinformed TV shows don't tell you that.
Since a bat can hear four times better than a typical
dog, they actually hear the mosquitoes’ wings. They also communicate among
themselves and avoid obstacles (like humans) with “echo-location”, which is sort of like
Doppler radar.
Bats also pollinate many crops. If your day includes
soap, shampoo, cosmetics, coffee, toothpaste, margarine, paper, ink, rope,
lumber, beer, candles, air fresheners, rubber, vegetables, spices, fruits, or
chocolates you are not simply helped by bats – you are dependant on bats.
Less than half of 1% of bats have rabies. They are not
carriers of rabies! If bitten, they’ll come down with it; just like any other
mammal. And, being so small, they usually die within a day. Actually, you have a much better chance of getting rabies from a pet
dog or cat.
Injuring, killing, or confining a bat is illegal in
Texas. Such acts (usually based on ignorance and superstition) need to be
reported. Specialty birding stores often sell different sizes of bat
houses. Providing housing for a free-flying bat makes you a “sanctuary”, and is
perfectly legal. Make sure the house’s design is approved by a non-profit,
rehabilitation group. Now, before they come back to the north Texas area
looking for homes, is the ideal time to put up a bat house, or for municipalities to promote what's almost certainly around already.
