SAN ANTONIO -- A natural way to reduce the risk against West Nile Virus could be as easy as putting up a bat house in your backyard.
One San Antonio man said using nature is an easy way to keep mosquitoes from invading his backyard.
Building bat houses started off as a hobby for Reggie Regan.
"(We were) just trying to find a way to control mosquitoes in our backyard without having to spray," said Regan. "We just built one and a friend wanted one and another wanted one."
His bat house building operation quickly grew into an international business.
"We've sold to every state in the U.S., every province in Canada, Italy, France, Spain," said Regan.
He's been building bat houses since 1992.
"Our bat houses are now certified through Bat Conservation International," said Regan.
It's a natural way he said to get rid of unwanted bugs and especially mosquitoes.
"They'll travel up to 50 miles in a single night just to feed themselves," said Regan.
A single bat can eat more than 1,000 of those pesky blood suckers. Regan said having one of these bat homes in your backyard could be one way of reducing the risk of West Nile Virus infection.
It may look like a mailbox but it's an ideal structure. There's no bottom to the home making it easy for them to fly in and out.
"Instinctively (they're) looking for those crevices just like a bird would find a bird house," said Regan.
Night video captured the creatures inside one of the homes. They actually like to hang out inside close together and when they're not sleeping they'll go out to hunt.
"So as those mosquitoes run for cover or get eaten they'll start spreading out," said Regan.
As for the fear of rabies, less than 1% of bats actually carry the disease.
