Here’s how you can tell if your house has termite damage. First, examine obvious areas of wood rot for termites. Some wood will look intact from the outside, but inside it may have been eaten away in a series of long tunnels. A sure sign of recent infestation is the presence of frass, which is termite excrement found on posts, beams, or siding. If frass falls out like dust, be sure to call an extermination specialist.
