1. General information about grain beetles

The grain beetle (Oryzaephilus surinamensis) is one of the most common stored product pests in households, warehouses, and food processing plants. The beetles are 2.5–3.5 mm long, narrow, brownish in color, and have distinctively toothed sides on their pronotum.

They infest a variety of dry foods: grains, flour, rice, oatmeal, pasta, nuts, and dried fruit . Females lay up to 300 eggs in food. The hatched larvae consume the food from the inside. Feeding, contamination, and moisture ingress can cause food to become moldy and unusable.

2. Detecting grain beetle infestation – typical signs

An infestation is indicated by various signs:

  • Small brown beetles (approx. 3 mm) that move quickly
  • Damage caused by gnawing and crumb formation in cereal or food packaging
  • Larvae in stock , whitish and worm-like
  • Clumped supplies due to moisture and mold growth
  • Sudden spread in the pantry or warehouse

Even a few beetles can cause severe damage to supplies in a short period of time.
