Termite frass are crucial early warning signs of termite colony activity. Drywood termite droppings appear as 1mm oval-shaped droppings with six concave sides, resembling coarse sand in dark brown colors depending on the wood type consumed. Unlike mouse droppings, termite pellets have a distinct hexagonal form and may emit a characteristic scent. Active termite frass often appear near window sills where termite galleries expel waste.
