Pest Control Beetles- Drugstore Beetles

Drugstore Beetles are small, 1/16 – 1/8 inch long, reddish-brown beetles with hard wing covers with long rows of tiny punctures, covered by short, fine yellowish hairs. Their head is usually held bent down, hidden from view when seen from above, giving them a humpbacked appearance. Their antennae have a “club” at the end that is made up of three equal-sized oblong segments (each about three times as long as it is wide). A complete life cycle (egg-to-egg) takes about 60-210 days, depending on temperature, moisture, and food supply. These beetles feed on a very wide range of materials; from grain to spices, and they may even feed on leather.They are one of the most common, stored products infesting beetles, and are distributed worldwide. The adults fly well and are attracted to lights. Pest Control strategies for other stored products pests are usually effective against these beetles too. All stages can be killed by heating infested materials to at least 140 degrees F for more than one hour, making sure that the middle of the materials is held at that temperature for at least that period of time, or longer.

A complete life cycle (egg to-egg) takes about 49-120 days, depending on temperature, moisture, and food supply.These beetles feed on a range of processed grain materials such as flour. Although this species probably originated in the Indo-Australian region, they are one of the most common stored product beetles, and are distributed worldwide. In the U.S., they are most common in the southern states.These beetles often cause a bad taste and odor in flour they infest, especially if infestations are heavy.

Pest Control Beetles strategies for other stored products pests are usually effective against these beetles too. AII stages can be killed by heating infested materials to at least 140 degrees For more than one-half hour; making sure that the middle of the materials is held at that temperature for at least that period of time, or longer; or by freezing the food item throughout to o degrees F or below for at least four days. You should place dry food in a ziplock type plastic bag before freezing to prevent it from getting wet due to condensation after removal from the freezer.

Pest Control BeetlesPest Control Beetles at Home:

You can eliminate these pests by taking the following steps.

You have to find the source of the infestation. Check packages you seldom use, especially items like cereals, grain products, nuts, flour, raisins, spices, dry pet food and birdseed. Make it a habit to thoroughly inspect all such items when you first bring them home from your grocery store. Pay special attention to all of the same items, and brand names, from the same store where any previously infested items were bought.

When found, you should wrap any heavily infested packages in a heavy plastic bag and dispose of them with your normal garbage.

Store all susceptible foods in tightly closed glass, plastic, or metal containers.

You should consider heating or freezing (as directed above) all susceptible food items you have had for 60 days or longer.

Usually, no pesticide treatment is needed for these pests. Finding and disposing of all infested foods should solve the problem. However, thorough surveillance for several weeks after removing an infestation is wise. A residual crack-and-crevice chemical treatment might be needed to eliminate stragglers that have remained hidden in the edges of shelves, pantries, or cabinets.
