How can I tell if my house has termites?
Check the surface of your foundation and around sills and joists for mud tubes. These are hollow, pencil-width tubes that termites use for shelter. Also check for an abundance of insect wings, especially between the months of March and May, when swarming termites shed them.
Termite droppings are another clue. These are small, sand-sized granules the color of sawdust scattered on the ground. For example, if you have exposed wooden rafters in your garage, look at the floor area directly below for these granules. Wood that has been hallowed out along the grain is also a sign of termites in action.
