Sleep Tight, Don’t Let the Bed Bugs Bite

Good night, sleep tight, don’t let the bed bugs bite is a phrase sometimes told to children at bedtime. However, in recent years, this saying has turned from a cutesy rhyme to an admonition worth repeating. The bed bug population across the United States has experienced a resurgence. What exactly are bed bugs? What is causing this explosion in bed bug population numbers? Is this something you should be worried about? And, what can you do to avoid bed bugs?

What are bed bugs?

The common bed bug (Cimex lectularius) belongs to a family of insects that feed exclusively on the blood of [warm-blooded] such as birds and mammals. One interesting fact about bed bugs is that, though they typically feed on blood every five to ten days, they can actually survive for over a year without feeding. Bed bugs feed by piercing their victims skin with an elongated beak through which they intake the blood. The bites typically go unnoticed because the bed bugs saliva contains a mild anesthetic that numbs the pain of the bite. The saliva also contains an anti-coagulant that keeps the blood flowing as they feed.

Bed bugs are particularly tiny–an adult bed bug is between four and five millimeters long. This small size lets them hide in really small spaces. Adult bed bugs are brown in color and have a flat, oval-shaped body. Nymphs (young bed bugs) are smaller in size and lighter in color than their adult counterparts.

These tiny insects are common nest parasites and are well-known inhabitants of bird nests and bat roosts. Over time, some bed bugs adapted to living among humans and have found the bedroom and other living areas the perfect place to set up their own home.

Bed bugs get their name from where they are commonly found in–that is, in beds. When not feeding on unsuspecting sleeping victims, bed bugs tend to hide within the crevices of beds mattress, box springs, or headboard.

Where are they found?

Bed bugs are not only found in private homes or residences. In fact, hotel rooms are one of the primary places where bed bugs can be found. Some researchers think the increase in international travel may be one why bed bug populations have boomed in recent years. Unsuspecting travelers may be transporting bed bugs in or on their luggage back to their homes.

However, bed bugs have been branching out in their choice of real estate lately, and have left the bedroom for offices, shops, and even movie theaters in some cases. New York City has particularly been affected by bed bugs in location outside their typical bedroom abode.

Dr. Jerome Goddard, a bed bug specialist and an associate extension professor of medical and veterinary entomology in the Department of Entomology and Plant Pathology at Mississippi State University, doesn’t see a world overrun by bed bugs in our future.

I think bed bugs will remain mostly a problem where people spend a lot of time sleeping or sitting, like a hotel, dorm, apartment, or perhaps trains and movie theaters, he said. I’m not too worried about them becoming widespread in retail stores where people just walk around.

Why are they back?

Due to the use of insecticides such as DDT, bed bugs were virtually eradicated from the United States after World War Two. Scientists point to the ban on DDT and other insecticides as one reason why bed bugs are back with a vengeance.

Dr. Goddard says that there is not one single reason as to why bed bug populations have surged. Instead, he points to several explanations, including changes in pest management practices, the development of insecticide resistance to the products we use for control, and a rise in international travel.

What are the signs of an infestation?

According to the Environmental Protection Agency, signs of a bed bug infestation include:

  • Dark spots about a mm in size
  • Eggs and eggshells that are white in color, about 1 mm wide
  • Shed nymph skins
  • Rusty or reddish stains on bed sheets or mattresses from crushed bed bugs
  • Live bed bugs

Those bitten by bed bugs typically experience a mild allergic reaction including raised itchy bumps on the bitten areas. Some people have no reaction to bed bug bites, while others have severe allergic reactions including anaphylaxis (closed airways). Though they feed exclusively on blood and may feed on more than one person during the course of their lifetime, several research studies have shown that bed bugs do not transfer diseases from one biting victim to another and, unlike mosquitoes, are not known to be vectors for infectious diseases.

How can I avoid bed bugs?

Methods to avoid bed bugs in general include checking hotel room mattresses, box springs, and headboards for evidence of bedbugs; keeping your luggage off the floor (some bed bug experts leave their luggage in the bathroom for the duration of their stay); reducing household clutter; and avoiding used mattresses or bed frames.

Combating a bed bug infestation takes a multi-faceted approach. Successfully treating a bed bug infestation requires the use of proper pesticides, the elimination of bed bug habitats, and cleaning items in the affected area. Non-chemical treatments for infected items include washing and drying bedding and clothing at high temperatures and/or heating infested items or areas to a temperature of at least 45 degrees Celsius (113 degrees Fahrenheit) for one hour or freezing infested items to -19 degrees Celsius (0 degrees Fahrenheit) for a period of at least four days.
