The weevil larva will then dig a gallery through the grain, and will widen it as it grows. Thus, during this development, the interior of the grain will be consumed. You will only find a food emptied of its substance, but containing excrement.
The weevil is a beetle that measures between 2 and 4 mm in adulthood. It is black, sometimes red and has an elongated shape and a flat back. Its physical appearance resembles that of a small beetle with a trunk and three pairs of legs.
To flush out the presence of weevils in your supplies, pour cereal or pasta, or beans into a clear glass jar. Then close the jar and shake it. After a few moments, you will see the weevils appear. These little insects can’t stand shocks!
