The increase in bed bug infestations in the U.S. is a result of increased travel, lack of knowledge about preventing infestations, increased resistance of bed bugs to pesticides, and ineffective pest control practices, explains the Environmental Protection Agency (EPA). It’s easy to mistake bed bugs for carpet beetles or similar-looking bugs, so infestations are often not noticed when they first occur. Prevention tips include keeping areas free of clutter, regularly washing sheets and mattress covers in hot water (and don’t forget to wash the laundry bag, too), and vacuuming regularly and safely disposing of the sealed vacuum bag. Not everyone has reactions to bed bug bites, which also may be mistaken for the bites of other pests such as mosquitoes, so timely bed bug extermination depends on identification of bed bug activity. If you notice physical signs of an infestation, contact a bed bug extermination professional as soon as possible to learn about chemical and non-chemical (such as heat) treatment options. An integrated pest management plan may incorporate one or more methods.
Bed bugs can travel into your home via luggage, secondhand furniture or clothing, and other items that have been exposed to the little pests. Bed bugs are tiny and flat (about the size of an apple seed and the height of a credit card), so they can easily hide in dark, small places and hitchhike into your home. According to the Centers for Disease Control and Prevention, most people don’t even know they’re transporting bed bugs as they travel from location to location, infecting areas as they travel. The sooner you notice a bed bug infestation in your home, the easier it is to get rid of it. The EPA suggests an integrated pest management plan to get rid of bed bug problems. This means a multi-pronged approach that takes the bug’s life cycle into account, uses chemical treatment where needed, and takes all necessary measures (use of encasements, high heat washing and drying of bedding, etc.) to stop current and future life cycles. Unless you feel confident about controlling a bed bug infestation, it can be wise to hire a pest management professional to prevent the problem from getting bigger.
There are several symptoms that can indicate you have bed bugs. The first is actually seeing the little pests skittering through your house. They tend to feed at night (generally where their hosts — people or sometimes animals — are sleeping), but can come out in the day if they’re hungry enough. Adult bed bugs are rusty red in color, as thin as a credit card and the size of an apple seed. Sometimes they can be mistaken for carpet beetles or small cockroaches, so if you’re confused you can use this helpful guide by the EPA for identification. Although they are harder to see, spotting the eggs themselves is a surefire sign. Another common symptom of having bed bugs is finding the exoskeletons of the nymphs near your bedding and other bed bug-friendly locations. The more exoskeletons you find, the larger the infestation likely is, because as they mate and proliferate more and more juveniles are born and cycle through moltings. Rust-colored spots — which the Centers for Disease Control and Prevention explains are blood-filled fecal dropping that the bugs excrete on bedding and furniture — are another sign that bed bugs are living in your home. In addition, a sweet, musty odor can be an indicator of bed bugs.
The EPA recommends integrated pest management as the most effective way to get rid of bed bugs. Integrated pest management (IPM) can be carried out by a pest management professional safely and swiftly. The professional will assess the level of infestation in your home or building. The pro will determine the sources of the bed bugs: whether they are hiding in one location, are occupying multiple locations in one room, or have set up camp in multiple locations throughout the house. Based on the severity of the infestation, IPM can include thoroughly cleaning the area using containment protocols (safely packing infested bedding and other items into plastic to be disinfected), the appropriate pesticide treatment, and the necessary follow-up to eliminate any new hatching eggs. The EPA recommends chemical treatments (when safely applied) because “although bed bugs may sometimes be controlled by non-chemical means alone, this approach is often very difficult, potentially less effective, and usually more resource intensive.” Use caution if you attempt to use pesticides yourself. Carefully follow directions and know that some bed bugs have developed resistance to pesticides. Pesticides that are licensed only for use by professionals are known to be stronger and should be applied with the proper tools and techniques.
Bed bugs are visible to the naked eye, but depending on where they are in their life cycle they can be hard to see. Adult bed bugs are the easiest to spot. According to the EPA, they are roughly the size of an apple seed and the height of a credit card. Adults are flat and oval-shaped, have six legs, and are rusty red in color. Bed bug larvae, also referred to as nymphs, are white-yellow or translucent in color and are much harder to spot due to their small size. The nymphs go through five stages of life, shedding an exoskeleton at each stage. Throughout these stages the nymphs grow in size from approximately 1.5 millimeters to approximately 4.5 millimeters. Bed bug eggs can be the most challenging to see as they are roughly 1 millimeter — about the size of a pinhead — and are white or clear. Bed bugs tend to be more active at night, as this is when they feed.
