[1] Sclerodermus domesticus preys on Coleoptera including Anobium punctatum, Stegobium paniceum, Lasioderma serricorne, Hylotrupes bajulus and Nicobium castaneum, or occasionally Lepidoptera.

Females are 2–5 mm long; they have a stinger but lack wings.

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.

There are reports of the species in Spain, Italy, France, Portugal, (Germany), United Kingdom, former Yugoslavia, Near East, United States and Costa Rica.

It can be found inside homes, mostly in old furniture, harboring woodworms.
