Sawtoothed grain beetles typically enter into homes in products that are purchased from stores which are already infested with the larvae or adults. The original infestation usually originates at the storage or packaging facility that the product came from.
The sawtoothed grain beetle’s flat body allows them to easily enter into broken kernels of grain and into food packaging. These beetles do not infest whole grains. Sawtoothed grain beetles typically feed on items that include breads, cereal, dry pasta, dried meats, candy, sugar, dried fruits, nuts, tobaccos, and other dry goods.
Sawtoothed grain beetles are not known to carry or transmit any dangerous diseases to people and do not bite or sting. They are considered to be nuisance pests, but will contaminate and damage food that is stored in your home.
