Stored Product Pests

Danger/Damage

Stored product pests put food items at risk. They can contaminate food by leaving body parts and cast skins inside.

For food processors, restaurant managers, or store owners, an infestation of stored product pests can mean a recall, consumer complaints, audit failure, brand damage, and loss of products.

No matter the size or severity of an infestation, a pest problem is not a situation to be taken lightly.

What are the most common stored product pests?

What do the red and confused flour beetle look like?

The confused flour beetle is more common than the red flour beetle in colder environments whereas the red flour beetles prefer warmer climates. Both beetles are reddish-brown and about 3-4 mm (1/8 inch) long.

The confused flour beetle is often mistaken with the red flour beetle, but the antennae of the confused flour beetle is gradually enlarged, whereas the red flour beetle's antenna enlarges abruptly to form a three segmented club.

The sawtoothed grain beetle is the most common of the two in unheated grain facilities. Both beetles are small and dark brownish, measuring about 2.5-3 mm (1/10 - 1/8 inch) long with six saw-like projections on each side of the thorax.

The adults of both species can be distinguished by head shape, and eye size. They can be found year-round in pantries, food processing areas and warehouses where any accessible food can quickly become a buffet. Despite their name, grain beetles prefer cereals, cake mixes, macaroni, cookies, and chocolate to grains.

Sawtoothed and Merchant grain beetles can quickly take over food products and contaminate them. Their body shape allows them to crawl in to packaging where they eat, live, and reproduce, allowing infestations to grow quickly.

Threats: Indian meal moths will infest available food sources, rendering them unfit for future use.

Prevention tip: Always store food in thick plastic or glass containers with airtight, secure lids to keep Indian meal moths from sneaking their way inside.

What are the breeding habits of the Indian meal moth?

Female meal moths lay eggs on the food, producing as many as 400 in 18 days. There are usually four to six generations per year depending on the food supply and temperature conditions.
