Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
The female lays her eggs in cracks in wood or inside old exit holes, if available. The eggs hatch after some three weeks, each producing a 1 millimetre (0.039 in) long, creamy white, C-shaped larva. For three to four years the larvae bore semi-randomly through timber, following and eating the starchy part of the wood grain, and grow up to 7 ...

Females are 2–5 mm long; they have a stinger but lack wings. They are black/brown, and have the appearance of ants. Females enter woodworm holes, paralyze the woodworm larvae with the venom of the stinger and lay their eggs in the corpses, which form the food for the S. domesticus larvae. This behavior leads to the common name of "antiquarian ...
