Termite droppings, scientifically known as termite frass, are distinctive oval pellets approximately 1mm in size with six concave sides and rounded ends. Fresh termite frass appears as neat, concentrated piles near termite kick-out holes, typically ranging in color from light beige to dark brown depending on the wood type being consumed. When termites feed on pine wood, the termite pine wood frass color tends toward tan, while termite oak wood frass color appears darker brown.
