Where are deathwatch beetles found?

Deathwatch beetles are commonly found in Europe and North America, typically inhabiting old wood, especially in decaying timber and structural wood in buildings. They thrive in damp, decaying environments where they can lay their eggs and their larvae can feed on the wood. These beetles are often associated with furniture, beams, and other wooden structures that are in poor condition. Their presence is often indicated by the tapping sounds made by the males, which are part of their mating ritual.
