description Deathwatch Beetle Overview
The deathwatch beetle, Xestobium rufovillosum, is a wood-boring beetle in the family Ptinidae. Its larvae tunnel through seasoned or decaying timber, and infestations can damage structural wood and old furniture when conditions are suitable. Adult males produce a repeated tapping sound by striking the head against the wood, a mating signal that was traditionally associated in folklore with death watches and the approach of death. The species is primarily associated with European timber and buildings.
