Brief SummaryRead full entry
BiologyThe adult beetles are usually active in late spring and early summer. They mate, and the females lay their eggs in crevices in wood, occasionally using existing furniture beetle exit holes (4). The larvae develop inside the timber, burrowing in and feeding upon the wood. The time taken for development depends on the type of wood and the temperature, but it usually takes more than 2 years for the adult to emerge (4). The fully grown larva creates a chamber just below the surface of the wood in which pupation takes place. It is the emergence of the adult beetle that creates the familiar round exit holes that indicate an infestation of furniture beetles (2).
