Biscuit Beetle

Biscuit beetles are closely related to the Common Furniture Beetle or wood-worm.

They are small reddish-brown insects, only about 3mm long, which attack stored foods. 

Flour, biscuits, cake mixes, cereals, spices, meat and soup powders will attract them, and they have even been found thriving on such poisonous substances as strychnine, belladonna and aconite - hence the beetle’s American name; Drug Store Beetle.

They have been known to penetrate tin foil and lead, and have even bored through a shelf-full of books.

The white larvae are very small and quite active when they hatch. They feed and grow for about four months before knitting themselves cocoons of food particles in which to pupate.



Remove any infested food and thoroughly clean out any food residues from areas where the beetles or their grubs are found; then apply insecticide on surfaces and into any crevices where they may lurk. Select a product labelled for stored product beetle control. Preferably use a trained pest control professional, with experience of stored product pests.
