Do Insects Bite Merchant Grain?

Merchant grain beetles are a common pest found in various locations worldwide, including Canada. They are similar in appearance and size to sawtoothed grain beetles but have some differences. Sawtoothed grain beetles do not fly, while merchant grain beetles can. Both beetles have running legs, similar to cockroaches, and can penetrate tightly sealed packaging. Both beetles are flattened, reddish-brown, and about 1/10-inch long.

Grain beetles do not bite or sting humans or pets, spread disease, or feed on or damage the house or furniture. They are not vectors for human diseases and do not bite humans. While they may bite, they are not known to feed on people. The potential troubles they pose are still something to take seriously.

Merchant grain beetles are considered nuisance pests as they live in common food and do not bite or sting humans. They are not known to carry or transmit any diseases to humans and will contaminate and damage food stored in homes. Adults can readily enter sealed cardboard boxes and soft plastic packaging.

The larval and adult stages of merchant grain beetles attack all foods of vegetable origin, with their preferred foods being oilseed products. They can fly but rarely do so. The larvae are 1/8 inch in length and sawtoothed and merchant grain beetles can chew through packaging in transit.

In summary, merchant grain beetles are a common pest found in various locations worldwide, including homes, grocery stores, food warehouses, and grain storage facilities. They do not bite, sting, or transmit diseases to humans, but they are a nuisance pest that can contaminate and damage food stored in homes.

Do Grain Beetles Bite Humans?

Sawtoothed grain beetles do not bite humans and pose no significant threat. Their small heads are unable to penetrate human skin, making them harmless. They are not vectors for any human diseases, which contradicts common misconceptions that they can bite or sting. While beetles generally might bite as a defensive action if handled roughly, it does not apply to grain beetles, as they are primarily pests that infest and contaminate stored food rather than humans.

Though they do not inflict harm, sawtoothed grain beetles can be annoying, often detected in living spaces due to their flying behavior and odor. Infested food should be discarded immediately due to contamination concerns. Beetles' jaws are designed for gnawing grains, and while they have chewing mouthparts, they do not damage houses or furniture, nor do they feed on clothing. Identified as nuisance pests, they do not transmit infections or diseases either to humans or pets.
