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 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.
Bed bugs can happen to anybody and there typically more than 200,000 cases in the U.S. per year. They are sneaky little pests that hitchhike into your home in a variety of ways. Getting a bed bug infestation is not a reflection on how clean a home is; bed bugs can infiltrate the cleanest of places — although their presence is easier to detect and eliminate in clutter-free spaces. Here are some tips from the EPA to prevent bed bugs from entering and taking up residence in your home:
- Carefully inspect secondhand furniture, beds, or couches for any signs of bed bug infestation before bringing them home.
- Use a protective cover (encasement) over mattresses and box springs to prevent bed bugs from hiding in them. Select an encasement in a light color to make bed bug spotting easier. Also choose one of a strong material that won’t tear, and check it often for holes.
- Keep your home clutter-free to eliminate bed bug hiding spots.
- Vacuum your home regularly and dispose of sealed vacuum bags carefully.
- Shared laundry facilities can lead to bed bug exposure in both directions. Transport laundry in plastic bags (if you have an active infestation, use a new bag for the journey home). Remove laundry from the dryer directly into the bag and fold it at home. Use high heat to kill any potential bed bugs.
- The EPA suggests that if you live in a multi-family home, isolate your unit by:
- Installing door sweeps on the bottom of doors to discourage movement into hallways.
- Sealing cracks and crevices around baseboards, light sockets, etc., to discourage movement through wall voids.
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.
