Bed Bugs

Bed Bugs

The common bed bug (Cimex lectularius) has long been a pest – feeding on blood, causing itchy bites and generally irritating their human hosts. The Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention (CDC), and the United States Department of Agriculture (USDA) all consider bed bugs a public health pest. However, unlike most public health pests, bed bugs are not known to transmit or spread disease.

They can, however, cause other public health issues, so it’s important to pay close attention to preventing and controlling bed bugs. 

Experts believe the recent increase in bed bugs in the United States may be due to more travel, lack of knowledge about preventing infestations, increased resistance of bed bugs to pesticides, and ineffective pest control practices.

The good news is that there are ways to control bed bugs. Getting good, solid information is the first step in both prevention and control. While there is no chemical quick fix, there are effective strategies to control bed bugs involving both non-chemical and chemical methods.

Bed bugs can be hard to find and identify, given their small size and their habit of staying hidden. It helps to know what they look like, since the various life stages have different forms.

Adult bed bugs, in general, are:

• about the size of an apple seed (5-7 mm or 3/16 - 1/4 inch long);

• long and brown, with a flat, oval-shaped body (if not fed recently);

• balloon-like, reddish-brown, and more elongated (if fed recently);

• a “true bug” (characteristics of true bugs include a beak with three segments; antenna that have four parts; wings that are not used for flying; and short, golden-colored hairs); and

• smelly, with a “musty-sweetish” odor produced through glands on the lower side of the body.

Young bed bugs (also called nymphs), in general, are:

• smaller, translucent or whitish-yellow in color; and

• if not recently fed, can be nearly invisible to the naked eye because of coloring and size.

Bed bug eggs, in general, are:

• tiny, the size of a pinhead;

• pearl-white in color; and

• marked by an eye spot if more than five days old.
