What are termite droppings?
Termite droppings, also called termite frass, are waste pellets left behind by certain types of termites. These tiny droppings can tell you a lot about the kind of termites you're dealing with and how active they might be.
Why termites leave droppings behind
Termites feed on wood and tunnel through it to build their nests. As they digest the wood, they excrete it in the form of fecal pellets. Drywood termites, in particular, push these pellets out of small holes, sometimes called kick-out holes, to keep their galleries clean.
What termite droppings can tell you about an infestation
Finding termite dust or termite droppings indoors may point to drywood termite activity. The size, shape, and location of the droppings can give clues about how widespread the problem is. Spotting small piles near wooden structures often means there's an active colony nearby.
