Sawtoothed Grain Beetles in San Juan
The sawtoothed grain beetle is a common stored products pest found throughout the nation in homes, grocery stores, food warehouses, and grain storage facilities. Similar in appearance to the merchant grain beetle, the merchant grain beetle has the ability to fly, while the sawtoothed grain beetle does not. Adults find their way into stored grains, flour, sugar, nuts and other dry material of plant origin through cracks and crevices of imperfectly sealed containers.
They are incapable of attacking sound grain kernels and often occur in food previously infested by other stored product pests.Their flattened body allows them to easily penetrate broken kernels of grain and packaged materials. Not only do they contaminate food, they often cause mold problems due to moisture build up.
Sawtoothed Grain Beetle Habitat
Sawtoothed grain beetles are commonly found in food manufacturing, storage, and retail facilities, as well as in home pantries. This stored product pest feeds on breads, cereal, dry pasta, dried meats, candy, nuts, and other dry goods. A single female can lay up to 250 eggs within cracks of kernels of grain. As with other pantry insects, it is the larvae that do most of the damage, however, the adult is most commonly encountered. A typical discovery of a saw toothed grain beetle infestation occurs when adult beetles are discovered crawling around a pantry area.
