Toothed Grain Beetle

Description:

The adult Toothed grain beetle is a small insect, no more than 2.5 mm to 3 mm long, having a light red to reddish-brown colour. The serrated grain beetle looks very similar to the Confused Flour Beetle, except for 6 sawtooth-shaped appendages on each side of the thorax.

​

Food:

The Toothed grain beetle feeds on a wide variety of foods that include cereals, bread, pasta, dried fruit, flour, cookies, powdered desserts, such as cakes and some spices.

​

Habits:

We find the Toothed grain beetle in supermarkets and other food stores from which they will be introduced into our homes with groceries. This flat-bodied insect can sneak into poorly closed and/or poorly sealed bags.

​

Reproduction:

The female lays 45 to 300 eggs, randomly in food or in packages in a crack of damaged grain.
