Citizens of College Station, Texas who spend time snuffing out termites in their homes would agree that extermination efforts can be time-consuming. Worse, since termite colonies aren't always readily visible, finding out about them might come too late. Thankfully, College Station pest control professionals like EcoZapp Pest and Termite have a solution to this: termite-detecting dogs. A dog's sense of smell can be 60 times better than that of the average human being (an article by Newsobserver.com notes that canine noses are about 95 percent accurate), and so what appears to be an invisible termite infestation to us is in fact quite detectable to trained canine senses.
