Cutaneous reactions to bedbug bites can vary widely and are easily confused with other conditions (Table 1).15–19 A typical lesion is a 2- to 20-mm, pruritic, erythematous maculopapule with a central hemorrhagic crust or vesicle.5,8 Macules, papules, wheals (Figure 3), vesicles, bullae, and nodules have all been reported,20 as have asymptomatic lesions with a barely visible punctum as the only evidence of a bite.8 Bites vary in number and are preferentially distributed in unclothed areas (e.g., face, neck, extremities). Unlike many other arthropod and insect bites, bedbug bites are rarely located in the popliteal fossae or axillae.21 Lesions can be noticeable immediately when waking up or several days later, with the reaction often progressing from delayed to immediate with subsequent exposures22–26 (Table 2). The classic bedbug rash is referred to as “breakfast, lunch, and dinner” because it commonly presents as several bites in a row or cluster 20 (Figure 4).
Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals. Cimex lectularius only feeds every five to seven days, which suggests that it does not spend the majority of its life searching for a host. When a bed bug is starved, it leaves its shelter and searches for a host. It returns to its shelter after successful feeding or if it encounters exposure to light. Cimex lectularius aggregate under all life stages and mating conditions. Bed bugs may choose to aggregate because of predation, resistance to desiccation, and more opportunities to find a mate. Airborne pheromones are responsible for aggregations.

Bed bugs do not transmit MRSA. Although there have been reports of persons developing methicillin resistant Staphylococcus aureus (MRSA) infections, such as boils or abscesses associated with bed bug bites, it turns out the bed bugs really weren't directly at fault. Rather, the cases of MRSA infections associated with bed bug bites are actually an example of scratching leading to minor skin trauma and subsequent secondary bacterial infections. In these cases, people who are carriers of MRSA scratch at the itchy bite sites and provide a port of entry for the MRSA (which was already present on their skin) to get in and under the skin and cause the secondary infection. While it can be blamed for some other bed bug symptoms like itching and red welts, the bed bug cannot be blamed for the infection.
just got back from two weekends of traveling to two diff locations. noticed a slight rash yesterday on the side of my ribs and a couple smaller itchy spots on one side of my stomach, etc. i don’t think it was from the first weekend of travelling as my bed companion didn’t get anything. the second weekend was at a college campus, but i had wiped the bed down before putting sheets and a sleeping bag over it. got back home sunday and noticed the itch yesterday (tuesday). so now i’m freaking out and assuming the worst scenarios. i’ve washed and dried all my clothes (though i did leave my suitcase out for two days before i even realized the itch), my sheets, and used a handheld steamer on my mattress, clorox / lysol the edge of my bed and the wooden frame, vacuumed all open areas on my wooden floor, etc. not sure if i should go to urgent care or what, but i’ve so far used hydrocortisone (previously already prescribed). can you please help or can i send you photos since you’re more familiar with this? never happened to be at home before all 20 something years so now i’m terrified i brought something back with me!
Avoiding repeated bites can be difficult, since it usually requires eradicating bed bugs from a home or workplace; eradication frequently requires a combination of pesticide and non-pesticide approaches. Pesticides that have historically been found to be effective include pyrethroids, dichlorvos and malathion. Resistance to pesticides has increased significantly over time and there are concerns of negative health effects from their usage. Mechanical approaches such as vacuuming up the insects and heat-treating or wrapping mattresses have been recommended.
I am afraid I have brd bugs on my couch.I’m not really for sure or not.I have been sleeping on it and I have been itching lately in different spots of my body.This morning I have a small bump on my left arm that looks like a pimple but its itchy.I just want to really know how to detect bug bugs so I can see if my couch has brd bugs on it.I’m really worried!
Just wondering if it is unusual for bed bugs to bite where you are clothed? I have 3 bites, in a diagonal line on one side and in a triangle shape on the other side of my pelvic area both which are covered by underwear at night. Then I have a random spot here and there on my legs. We have a plastic mattress cover on our bed but use dark sheets. As best I can tell there is no evidence of bed bugs. What do you think? Thanks!
Some pest control firms utilize specialized heating equipment to de-infest furnishings, rooms, and entire dwellings. The procedure involves heating up the infested item or area to temperatures lethal to bed bugs. Portable heaters and fans are used to gradually heat the air to about 120 - 130°F while monitoring with strategically placed sensors. By carefully controlling the temperature, bugs and eggs are killed wherever they may be without damaging household items.
