Bed bug facts and information

Bed bugs are a growing concern in the United States and beyond, known for their resilience and ability to spread quickly. These wingless insects are nocturnal pests, feeding exclusively on blood and often hiding in hard-to-reach places around the home. Bed bugs, scientifically named Cimex lectularius, have caused discomfort and anxiety for centuries, leaving itchy welts on their victims and creating difficult infestations. 

What are bed bugs?

Bed bugs are small, parasitic insects that primarily feed on human blood. They belong to the Cimicidae family and thrive in a variety of environments, particularly in homes, hotels, and public transportation settings. Their feeding habits and ability to hide in the tiniest crevices make them particularly troublesome, as they emerge at night to bite humans while they sleep. Bed bugs are commonly associated with unclean environments, but they can invade even the cleanest of spaces due to their adaptability and rapid reproduction.

Physical characteristics of bed bugs

  • Size: ⅛” - 3/16” in length as adults
  • Color: Brown or reddish-brown
  • Body: Flat, round bodies divided into three segments, six legs, and two antennae

Adult bed bugs are reddish-brown and about the size of an apple seed, measuring around 4–5 millimeters in length. They have a flat, oval-shaped body that becomes swollen and red after a blood meal. Young bed bugs, known as nymphs, are smaller and lighter in color, often nearly translucent. After feeding, their bodies turn darker. Bed bugs are also wingless, which helps distinguish them from other small household pests like ants, fleas, cockroaches, or termites.

Common habitats and hiding spots

Bed bugs prefer to hide close to their feeding sites and are often found in mattresses, box springs, and bed frames. The tiny cracks in headboards and even seams in mattresses provide ideal spots for them to live and reproduce. They may also inhabit other furniture, such as couches or upholstered chairs, where they can stay close to human hosts. Bed bugs are skilled at finding any crack or crevice, including areas behind baseboards, around wall outlets, and in floors or walls. Their ability to remain undetected until an infestation grows makes bed bugs a particularly challenging pest to control.

Common species of bed bugs

Cimex lectularius (common bed bug)

Cimex lectularius is the most prevalent bed bug species in North America. These bugs are highly adaptable to human environments and prefer moderate temperatures, which makes them common in residential areas. Cimex lectularius prefer human blood but may also feed on other warm-blooded animals if necessary.

Cimex adjunctus (bat bug)

Often mistaken for common bed bugs, Cimex adjunctus or "bat bugs" have a closer association with bats. These bugs inhabit areas where bats are present, such as attics or wall voids. If bats vacate these spaces, bat bugs will seek alternative blood sources, including humans.

Bed bug life cycle

Stages of development

A bed bug starts out as an egg that hatches into a nymph. Before each life stage the bed bug molts, leaving shed skins behind. Discarded bed bug skins are often one of the first signs of an infestation. Once the bed bug hatches, it seeks out a host to get a blood meal.

A bed bug goes through several nymph stages before reaching adulthood. When they are in the nymph stages, they are very small and hard to see. When they reach adulthood, they are about the size of an apple seed.

Female bed bugs will lay up to five or six batches of 10-15 eggs per day. Bed bug eggs are roughly 1mm long and are pearly white in color. Eggs can often be found near where the adult and young bed bugs hide during the day.

After hatching, a bed bug goes through five nymph stages before reaching adulthood. They are very small and difficult to see during this time. During their first cycle, these nymphs are white-colored, but they get darker as they grow and consume blood meals. Before each life stage, the bed bug molts and leaves shed skins behind. Discarded bed bug skins are often one of the first signs of an infestation.

An adult bed bug is brown and flat in appearance (unless it is engorged with a blood meal) with a wide head and segmented body. They are about the size of an apple seed, 1/4 inch in width, and are typically reddish-brown in color, especially after feeding. Bed bugs do not fly, but they do crawl quickly and often latch onto suitcases or clothes. An adult bed bug can last as long as one year without a meal.

Reproductive habits

Bed bugs reproduce rapidly, which is one of the reasons why infestations can become severe in a relatively short period. Female bed bugs lay multiple eggs daily, which hatch quickly and contribute to rapid population growth. The ease with which bed bugs spread means that a few initial bugs can lead to a large infestation in just a matter of months.

Bed bug behavior

Bed bugs want two things: to hide and to feed on blood. Below are some facts and characteristics about a bed bug's living environment and its feeding habits.

Feeding patterns and preferences

Bed bugs are nocturnal feeders and are generally attracted to their hosts by the carbon dioxide that humans exhale and the warmth of human bodies. This is why bed bugs tend to bite exposed skin on the arms, face, and neck during sleep. They feed on blood every few days if conditions are favorable. Interestingly, bed bugs inject an anesthetic into the skin before biting, which minimizes the immediate sensation of the bite and allows them to feed undisturbed. After feeding, bed bugs retreat to their hiding spots until they require another meal.

Bed bug movement and spread

Bed bugs can travel short distances by crawling but are also known to hitchhike on items like luggage, clothing, and furniture, making travel a common means of spreading infestations. In multi-unit housing, bed bugs may migrate between rooms or apartments through cracks in walls or floors. This adaptability and mobility mean that bed bug infestations often spread before people are even aware of the problem.

 

Health risks associated with bed bugs

While bed bugs are not known to transmit diseases, their bites and presence in homes can lead to several health issues, both physical and psychological.

Allergic reactions and bites

Bed bug bites often appear as small, red, and itchy welts, usually in clusters or lines on exposed skin. Reactions to bed bug bites can vary, with some individuals experiencing severe itchiness, swelling, or even allergic reactions that require medical attention. In rare cases, scratching these bites excessively can lead to secondary skin infections.

Psychological impact

The presence of bed bugs can lead to psychological stress, as well as disrupted sleep due to anxiety over being bitten. The stigma associated with bed bugs may also lead to embarrassment and stress. Infestations can cause a significant amount of emotional distress for affected individuals, leading to insomnia and heightened anxiety.

Identifying a bed bug infestation

Identifying the early signs of a bed bug infestation is key to preventing further spread and ensuring effective treatment.

Signs of infestation

Bed bug bites are often the first sign of an infestation, with small, red, itchy welts appearing on the skin. Other common signs include small reddish or dark stains on bed sheets, which may be the result of crushed bugs or bed bug excrement. The presence of tiny, white eggs or molted exoskeletons in mattress seams, bed frames, or other crevices is another indicator of an infestation. In cases where the infestation has progressed, live bed bugs may be visible in their hiding places, such as mattress seams or behind baseboards.

Bed bug detection methods

Regular visual inspections of mattresses, box springs, bed frames, and furniture are essential for early detection. Professional pest control companies like Ehrlich may use specialized tools like bed bug-sniffing dogs or heat sensors to detect bed bugs in harder-to-reach areas. Monitors that attract bed bugs and capture them to confirm an infestation can also be used.

Prevention tips for bed bugs

Preventing bed bugs requires a proactive approach, especially when traveling or bringing second-hand items into the home.

Travel precautions

When staying in hotels, it is crucial to inspect the room carefully. Check the mattress, bed frame, and headboard for any signs of bed bugs before unpacking. Avoid placing luggage on the bed and keep it elevated, preferably on a luggage rack. After traveling, wash and dry all clothes on high heat to eliminate any potential hitchhikers.

Home prevention strategies

At home, regularly inspect mattresses, box springs, and other upholstered furniture for signs of bed bugs. Sealing cracks and crevices in walls, floors, and furniture can reduce potential hiding spots. Reducing clutter also minimizes places where bed bugs can hide and makes it easier to detect infestations early.

Treatment and control options

Eliminating a bed bug infestation is challenging and often requires professional intervention for lasting results.

Professional extermination services

Professional pest control companies like Ehrlich offer a variety of bed bug control methods, including fumigation, heat treatments, and pesticide applications. Our Integrated Pest Management (IPM) approach combines regular inspections, targeted treatments, and preventive measures, allowing our technicians to effectively control bed bugs.

DIY methods

Some home remedies for bed bugs can help reduce the number of bugs temporarily. Vacuuming and steam cleaning are two effective DIY methods to remove bed bugs from furniture and mattresses. High heat is also lethal to bed bugs, so laundering infested items on high heat and using mattress and box spring encasements can help control the infestation. However, it is important to understand that you are unlikely to completely eradicate an infestation without professional help.
