Repeated exposure to bed bug bites for several weeks and months can sensitize you to the saliva, and you can develop mild to intense allergic reactions. Some people’s skin does not react to bed bug bites. Some unlucky others develop severe rashes or blisters.
Some people’s skin does not react to bed bug bites. Some unlucky others develop severe rashes or blisters. Even when they are sharing the same bed, their skin can be affected differently.
Approximately 50 to 70% of people develop an allergic reaction to the saliva injected by the bed bugs. This usually results in small, flat or raised bumps, red, swollen, and itchy skin. The bed bug bite areas can become infected when scratched.
The effect of bed bug bites varies, and everybody’s reactions are different. Bed bugs require blood to feed and reproduce. Their bites usually cause itchy red welts.
Usually, when bed bugs bite, you won’t feel the pain. If you are living with a significant infestation, your sleep will be disturbed, and your skin will become more sensitive. You could experience notable blood loss and anemia.
As the bug numbers rapidly increase, the problems usually become much worse. Health problems grow, and the added social stigma affects victims of bed bugs significantly.
“There is no evidence that bed bugs are involved in the transmission (via a bite or infected feces) of any disease, including hepatitis B virus and HIV, the virus that causes AIDS.” (Source)
When a bed bug feeds, it inserts saliva into its blood-meal host, usually causing an allergic response. How your body will respond much depends on your immune system.
Yes, they are. According to one study, 72% of people have itchy red welts, and 28% percent have to itch in the absence of welts.
Our bodies respond in different ways at different times. Bites are more likely to itch if you are overheated, such as in a warm bath or shower, during exercise or in a hot car.
Usually, you can’t feel them. Bed bugs prefer not to climb onto you as they feed. Bed bugs crawl along the edge of the exposed skin, seeking for a suitable feeding spot. This can cause bites to occur in rows.
Bed bug bites create minor swelling, local reddening, itching, and inflammation of your skin. Itching can be very intense.
The skin reaction to a bed bug bite may be delayed for up to two weeks, mainly if it is the first time that you have been bitten. That leads to delays in the detection of an infestation.
The duration of a bite will depend mainly on your body’s ability to heal itself. If you scratch a bite, then it becomes a wound, open to secondary infections. When left unscratched, the bite will usually heal without scarring.
Bed bug bites in a line can be small or large, flat or raised, red welts to rashes, hives, or blisters.
Yes, they do. Bed bugs can bite any exposed skin. Most bed bug bites occur on the chest or back, neck, hands, feet or face.
Bed bugs commonly like to feed an hour or two before sunrise, when you sleep. They can bite you in the daytime if they’re starving. When you sit for a long time on an infested chair or sofa, bedbugs will be forced to feed while you are there.
Bed bug bites show up in a cluster of red bumps, a row of several bites, or in a zig-zag line.
Bed bug bites can occur alone, but they tend to bite multiple times since they often “test” a few areas first to locate the best source of blood for their meal.
The classic “breakfast, lunch and dinner” bite patterns it is not very common. Often, bed bugs can get enough food from a single piercing. If it is unable to get a full meal due to a tricky spot on your skin or some other factor, then it may need to pierce again in a close cluster.
Environment, stress, and many other factors can result in an old bite flaring up. Some people just think about bed bugs and bites appear again.
As high as 60% of all exposed people never react to bed bug bites, and they can live unaware of the fact that they have bed bugs. The rest develop from mild to severe reaction.
You could respond immediately to bedbug bites, or develop some reaction up to 21 days later, depending on your immune system. This is the reason for an infestation going undetected for a very long time.
They look different for different people. Some have an extreme reaction and develop severe swells like a blister. Others have nothing more than a red spot that fades away after a few minutes.
Bed bugs crawl along the edge of the exposed skin, exploring for any suitable feeding spot. They could attack any inch of your skin.
The skin of your body responds differently. As a rule, try to avoid bed bug bites on your hands, feet, and face as they tend to react the most. If you develop bullous/blisters within a few minutes, seek immediate medical attention.
According to the CDC, bed bugs are not a health risk for the public; they don’t spread any pathogens or transfer any disease.
There are a few reports of systemic allergic reactions from bed bug bites, like asthma, generalized hives, and anaphylaxis (Source).
Bed bugs do carry 24 known pathogens, but do bedbugs transmit disease? Nope, bed bug bites won’t make you sick unless, of course, the bites get infected.
While bed bugs do feed on blood, they don’t spread AIDS or other blood-borne illnesses. If you’re bitten by bed bugs, the only things you need to worry about are not scratching the bites until they bleed and finding a way to control the itching.
Bed bug scars and marks on the skin can last for weeks and in some cases, result in permanent scarring. For advice from Dr. Loretta Ciraldo, check the video below:

There is evidence that subsequent infections from bed bug bites can cause significant problems for some people:
Modern research has already answered the question: “Can bedbugs make you sick?”. It is confirmed that there is no evidence that bugs can transmit diseases. Still, this does not mean that bed bugs should be excluded from a medical standpoint. Bed bugs and bed bug bites are a pain to deal with. We must take all necessary measures for their prevention and control.
BEDBUGS are a nasty pest that no one wants in their house. But even when they are gone they leave traces behind that can cause allergic reactions and even asthma attacks. When bedbugs poop in your bed they leave behind a chemical called histamine, which causes allergy symptoms in people.
According to PCT Online, bed bug histamines are substantial, persistent in infested homes
New research findings could turn perceptions of the already despised bed bug from nuisance pest into a medically important threat. A study from North Carolina State University shows that histamine levels are substantially higher in homes infested by bed bugs than in pest-free homes and that these histamine levels persist for months – even if the bed bugs have been eliminated from the home. It is histamine that causes your runny nose, itchy eyes, sneezing and trouble breathing. (Source)
“Histamine levels in bed bug infested homes were at least 20 times higher than histamine levels in homes without bed bugs,” DeVries said. “And these levels didn’t decrease much three months after treating the infested homes with heat and insecticides.”
In humans, histamines are generally released as part of an immune response. They cause inflammation and help allow other immune system chemicals to fight a pathogen or to do cellular repair work. Histamines, though, can have deleterious effects in humans, including rashes when contacted with skin and respiratory problems when inhaled – think of the allergic reactions to certain foods, pollen, mold or other environmental conditions.
“Histamines are used in skin and respiratory allergy tests as a positive control – they cause a bump in skin tests and restrict breathing in respiratory tests,” DeVries said.
Bed bugs naturally give off high levels of histamine in their feces; DeVries says that bed bugs use histamine as a marker of a good place to aggregate. When bed bugs find their way into homes, they tend to aggregate in bedrooms where sleeping humans – the food source for bed bugs – spend a good part of their day.
Bed bugs have become a major social, economic, and health problem since their global resurgence in the early 2000s. Infestations can reach exceedingly high levels, especially among the elderly and in disadvantaged communities, where interventions may be unaffordable.
While bed bug bites have been recognized as a dermatological concern that can be exacerbated and lead to secondary infections, bed bugs have not been implicated as disease vectors or allergen producers. The results of this study demonstrate that the presence of bed bugs strongly correlates with histamine levels in homes, and thus may adversely affect the health of residents through exposure to exogenous histamine.
Furthermore, bed bug eradication with heat and insecticides does not appear to reduce histamine levels in homes, suggesting high thermal and chemical stability of histamine.The intimate association of bed bugs with humans and the spatial distribution and persistence of histamine in homes suggest that histamine may represent an emergent indoor environmental contaminant whose impact on human health should be investigated.
