Anobiid / Deathwatch Beetles (Anobiidae)
Anobiid beetles, commonly called deathwatch beetles, are wood-boring pests known for the tapping sound adults make inside infested timbers. Their larvae feed on the starch and cellulose in seasoned hardwood and softwood, potentially weakening structural elements over years. Damage is often hidden and discovered only when exit holes appear on wood surfaces. Professional fumigation or targeted residual treatments are recommended to stop active infestations.
