A term frequently misused to describe beetles in general, but is applicable only to a distinctive group of beetles with long, pointed “snouts” which they use for boring into whole grains, hard processed cereals such as pasta, and timber. Mainly pests of stored cereals on farms.
If you find them in foodstuffs, return them to the shop and complain. The affected food should be destroyed. Spray cleared shelves with aerosol or put the powder in cracks and crevices. Choose a product labelled for stored product insect control.
Use a professional pest controller.
