The first sign of a termite infestation may be wormlike mud tunnels that run up walls or foundations. Termites are particularly attracted to damp wood which may be found in basements and tunnels, so termites are often discovered either within basements or emerging from them. The tunnels are created by subterranean termites who uses their feces, or frass, as part of the building material for the tubes.
Mysterious piles of pellets are indicative of drywood termite presence. These piles could be drywood termite droppings known as frass. Drywood frass can be different colors, depending of the color of the wood termites have been eating, but all drywood droppings are six-sided.
Sagging floors and ceilings result from both subterranean and drywood termite infestations. In the event of more severe infestations, wooden surfaces may become so compromised that they buckle or collapse. By the time signs of termite presence become visible, it is highly likely that a home is already experiencing a full-blown infestation. In the event of any signs of termites, contact a termite control professional to discuss treatment options.
