In 1918, Albert Steves erected a Hygieostatic Bat Roost on his family farm in Comfort. This roost was built to attract bats in an effort to control mosquito populations by natural means. It was originally researched and developed by Dr. Charles Agustus Rosenheimer Campbell of San Antonio. The idea was to use bats against malaria-carrying mosquitos. At one time, there were sixteen bat roosts built in the United States and Europe, of which only two sites now remain — one in Comfort and one in the Florida Keys.
