The larvae of these tiny beetles feed within decaying wood, occasionally attacking pilings and other structural lumber that is in damp and poor condition. Their life cycle is quite unusual, with almost all of the individuals found in wood females, either in the larval stage, the adult beetle stage, or as an adult “larviform” female that never changes to the beetle appearance. These females may give birth to living larvae themselves.
They may be discouraged by eliminating the excessive moisture condition. Their presence in wood may indicate that the wood is no longer structurally sound and may need to be replaced.
