Several beetles are common pest of stored food products and often occur in houses, bakeries, grain stores and warehouses – anywhere that food is stored, especially dried food stuffs such as grain, cereals, flour, nuts, etc. It is always advisable to keep such foods in well sealed plastic or glass containers – this not only keeps vagrant beetles out, but also prevents the spread of insects which might be introduced accidentally (often as eggs and/or larvae) with newly purchased goods.
Some of the stored food pests, and a variety of other beetles that frequently invade human habitations, can also damage clothing, carpets and other household furnishings, attacking almost anything made from natural fabrics and furs. Most of these beetles will not attack man-made fibres (nylon, polyester, acrylic, etc.), so that clothing and furnishings made from these materials are relatively safe from beetle-damage.
