The nice thing about an emergency pest problem, like the current bed bug epidemic, is that such problems attract a lot of attention from the research community. A few weeks ago I reported new research from the Wang laboratory at Rutgers University on some interesting facts about bed bug infestations in high rise apartments. In the same journal two British scientists from the University of Sheffield, R. A. Naylor and C. J. Boase, report on another aspect of bed bug management...how to kill bed bugs in bedding and clothing using laundering procedures.

Knowing how to dis-infest clothing is important to pest control, because, as the authors so carefully explain, bedbugs "may seek harborage among clothing stored close to the bed, or may be entangled with bed linen while it is being changed. " And, "once associated with clothing or linen, there is a risk that bed bugs may then escape insecticide treatments, and may be transported to new locations."

Although there have been many recommendations on the Internet and in print concerning how to dis-infest laundry, Naylor and Boase point out that such recommendations are often vague or conflicting and have been based on little formal research. So they set out to look at the temperatures and conditions necessary to ensure 100% mortality of adult, nymph and egg stages of bed bugs.

To do this they took laboratory reared bed bugs and sealed them in cotton bags. These bags were then placed among sheets or in the pockets of clothing to assess mortality of standard cleaning methods. The results were enlightening and should help in recommendations for how your customers can ensure maximum effectiveness of methods to disinfest household articles.

A summary of the results of this study include the following:

Insects in the City: Guidelines for killing bed bugs in laundry

Bed bugs are small, wingless insects that have not been known to transmit disease. Adult bed bugs have flat, oval shaped bodies. They are between 1 to 7 millimeters in length (about the size of an apple seed). The size of an adult bed bug varies, because their bodies become larger after a blood meal. After eating they change to a reddish color. Bed bugs are usually active at night and bite humans and animals while they are sleeping. They can live several months without feeding.

Bed bugs can be found anywhere, such as houses, apartments, group living situations, hospitals, hotels/motels, and public transportation vehicles. These places have areas where people sleep or spend significant amounts of time. Their usual hiding places are in seams of mattresses, box springs, bed frames, and along and/or directly behind headboards. Once a bed bug population multiplies, they can be found: behind baseboards; in cracks and crevices in furniture, floors, or walls; under cluttered areas; and in electronic appliances. A bed bug infestation is apparent by noticing black or brown spots (which are their waste products) on surfaces. The eggs, egg shells, and exoskeletons of the bed bugs can be found in their hiding places as well.

Because bed bugs can be found in homes and a variety of public places, they can easily be transported from place to place by people. They can hide in the seams of luggage and in the folds of clothing. They can also be transported in furniture.

Bed bugs are not known to transmit disease, but many people have mild to severe allergic reactions to the bites. Bed bug bite marks usually appear on the face, neck, arms, hands, but can appear on other body parts. The marks are slightly swollen, red areas that can itch or be irritating.

It usually takes multiple visits by licensed pest control operator who has experience in elimination of bed bugs. Please seek the advice of a licensed pest control operator for treatment options. Over the counter foggers and pesticides will not eliminate bed bugs.
