Common in the UK the adult beetle is about 2-3 mm shaped like a ladybird, the adults
feed only on pollen and nectar.
The larvae around 5mm long and covered in short bristles ( woolly bears ) eat animal
protein, wool, leather carpets and clothing.
The female lays eggs on a suitable protein source, often an old birds nest where
the larvae feed on droppings and feathers. The larvae grows , moulting 4-5 times
before pupating in the final larval skin. When hatched the adults will fly in search
of pollen, often found on a window ledge looking to make their escape. They return
to buildings in the autumn to lay eggs.
Control is with good housekeeping and residual insecticide sprays or dusts.
