Vanguard Exterminating is a family owned and operated full-service exterminating business. Sandy Thomas is a second-generation termite specialist who loves the challenge of finding a blind, foraging bug in the dark. "It's just as dark under the house at night as it is during the day," says Thomas. It's for this reason that she makes services calls around the clock. Thomas will issue homeowners, or new buyers, official wood infestation reports.
