Sawtooth Grain Beetle


A sawtooth grain beetle gets its name from its saw-like teeth that are found in the first segment of their bodies. They are usually found near stored products, like inside your food pantries. Unfortunately, they can be found in homes, or in commercial facilities, and can cause major headaches for anyone that comes in contact with them. They are quite small and brown in color. If you have noticed these pests, you may have an infestation. Call Nashville Pest Control today and have them come prevent them for you.

Appearance and Life-cycle:

As stated before, the sawtooth grain beetle is brown in color and about 2.5-3 mm long. Their bodies are flat. They have six projections behind their heads, on each side, that serve as a magnifying glass to help them see what is behind them. The female beetle lays her eggs in cracks that are in food, like flour. After the eggs hatch, the larvae will feed on the food products stored in your pantries and grow into adults. Before becoming an adult, the larvae make cocoons with materials from your food products. Their entire lifecycle lasts about two months, and there can be several generations within a year.

Habitat and Behavior:

Sometimes, the sawtoothed grain beetle, and the merchant grain beetle are confused by people. The way to tell them apart is if they fly, they are merchant grain beetles. Sawtoothed grain beetles do not fly, and they are not attracted to lights. You will usually find them in in your spices cabinet, as they are attracted to flour, chocolate, nuts, different kinds of spices, birdseeds, etc. Their flat bodies allow them to wiggle through cracks and crevices.

Level of Danger:

Sawtooth grain beetles are not dangerous, nor do they transmit any kind of diseases. However, they are a nuisance to everyone they come in contact with. They are also a nuisance pest because they infest food products that you store in your kitchen and pantry areas.

Signs of Infestation:

The only real way to know if you have an infestation is by seeing them run across your pantries, counters or shelves.
