Bat boxes put up in northern Columbus give pest control new look

Twelve new houses have gone up in northern Columbus, each accommodating as many as 150 residents. And although these residents are expected to eat out every night, area restaurants won't see an uptick in business. These houses were built for bats, and if one backer is right in his calculations, the inhabitants could save the city as much as $15,000 a year in mosquito-spraying costs.
