The Sawtoothed Grain Beetle is VERY flat, very narrow, and very small. It has been proposed that it is so small and flattened that it might even be able to work its way into a jar with a loose lid on it by following around the screw-cap ridges inside that lid. It is one beetle that service technicians run across most frequently and it usually is very difficult to trace to its source because of the wandering habit of the adult beetles. Imagine the top of a box of breakfast cereal. When you buy it at the store it is sealed shut. Or is it? The glue that is applied on the flaps to seal the box shut doesn't always provide a 100% seal. Even though the flaps look securely glued down if there is ANY crack that is not glued down, the very small, very flat Sawtoothed Grain Beetle adult can easily enter. It is difficult to design a practical package that will keep them out.
It is easy to identify the Sawtoothed Grain Beetle because of the six "saw-like" projections on each side of the thorax that can be seen even without the use of a hand lens. This kind of a toothed edge is referred to as “serrated”. This beetle has well developed wings but it does not fly, but a very closely related species called the Merchant Grain Beetle CAN fly and may be the more common of the two species infesting our residential foods, given its stronger ability to move from place to place by flying. These two species and the differences between them are these:
This very slight but noticeable difference between these species is a great way to distinguish one from another, but in the real world it is not terribly important. Both kinds infest the same kinds of food products and are controlled in a similar manner. The Sawtoothed Grain Beetle occurs widely throughout North America and the world, and this is referred to as being “cosmopolitan”. They infest a great variety of foods and are very commonly found in home kitchens and pantries. This list includes nearly all stored grains and grain products, especially wheat, corn and barley. Other products that may be infested are flour, corn meal, corn starch, macaroni, breakfast cereals, wheat bran, oats, alfalfa seed, bird seed, dog food, graham crackers, herbs, spices, dried fruit, cocoa, nutmeats, dried figs, raisins, oil seeds, cookies, cake mixes, palm tree products and candy bars made with peanuts or puffed rice. They also infest cereal-based rodent baits.
At Lady Bug we use a variety of environmentally responsible products to control pest activity. The ECO line of products we use are all EPA approved and are made from clove oil, guava fruit, rosemary and other organic products and naturally occurring materials. They are very effective against pests when injected into the cracks and crevices at the source of where pests live and breed, yet it is inaccessible to people and pets.
