Primarily nocturnal, a pest of warm, humid conditions. Found in the UK only in heated buildings, not normally outside or in underground heating ducts. Nymphs and adults cluster in groups in harbourages when inactive attracted by aggregation pheromone. Prefer narrow harbourages close to food and water source. Forage on a wide range of foods and need access to free water. Can climb smooth surfaces.

Nymph - 5-7 moults taking from 2-6 months to reach maturity. Live and feed with adults. Adults - small active, yellowish brown, living on average 6 months. Winged but do not normally fly.
Serious pest in heated buildings where it may rapidly spread if conditions are suitable. May carry disease organisms.
Application of residual insecticide to all known harbourages, flooring, walls, cracks and crevices etc. Only to be undertaken by qualified technicians.
