Telltale signs of termite infestation include softwood in the home, small mud tubes on the exterior of your home (often near the foundation), darkening or blistering of wood structures, hollow wood, and kick out holes in boards. There might be small piles of round pellets in spaces around the home. Termites use the kick out holes to remove waste as they tunnel.
If left untreated, termites can cause thousands of dollars in damage. They come as a colony, which means they are eating through your wood 24 hours a day, 7 days a week. It is estimated that termites destroy $5 million of property annually. They can be controlled and eliminated, but only if caught early on and treated by a pest control professional.
