Protachivaya the fibers longitudinal passages, she densely scored their droppings, mixed with small bits of wood. Before pupation the larva moves to wash the wood surface, leaving not only a thin protective progryzennym (about 1 mm) layer, from which immediately same suits again deepened and pupal "crib." The pupal stage lasts about two weeks, the adult beetle lives up to one month, and the full life cycle usually takes a year, though it depends on the temperature and can vary – from 6 months to 2 years. Females lay eggs on non-lacquered or painted door frames, window sills, not plastered ceilings, beams, baseboards, etc. Among the furniture beetle often turns into a board floor, piles, beams.
