Bed bugs are small parasitic insects that consume blood, typically at night while their host is sleeping. Although they may bite everyone in a household, some people experience bites more frequently than others. Bed bug bites often result in red, itchy bumps, but why do these pests appear to favor some individuals over others? Let’s explore the factors behind this mysterious behavior and how to address it effectively.How Do Bed Bugs Feed?
Bed bugs are insects that consume the blood of humans and animals. Bed bugs are opportunistic feeders that prefer to feed while their hosts are asleep. Using their specialized mouthparts, called stylets, they pierce the skin and draw blood. During feeding, bed bugs inject saliva containing anticoagulants to prevent clotting. This process typically lasts 5–10 minutes and can leave behind itchy, irritated welts. What makes bed bugs particularly troublesome is their ability to hide during the day, making it difficult to detect an infestation until it’s already well-established. Bed bugs’ nocturnal habits and painless bites mean many people remain unaware of their presence until they start seeing bites or the pests themselves.
Why Do Bed Bugs Bite Some People and Not Others?
While bed bugs don’t intentionally select specific individuals, various factors can increase somebody’s chances to get bitten: Body Chemistry Bed bugs are attracted to carbon dioxide, body heat, and sweat. Individuals who emit more carbon dioxide or have higher body temperatures may draw more bed bugs. Unique body odors and skin chemistry can also play a role. Blood Type Some studies suggest bed bugs may prefer certain blood types, such as type O. However, more research is needed to confirm this theory.
Immune Response
Not everyone reacts visibly to bed bug bites. People with strong immune responses may develop noticeable red, itchy welts, while others may show no reaction at all. This difference can create the impression that only certain people are being bitten.
Allergic Reactions
Some individuals are more allergic to the saliva injected by bed bugs during feeding, leading to more pronounced swelling, redness, and itching. This heightened reaction makes bites more noticeable.

What do Bed Bug Bites Look Like?
Bed bug bites typically appear as small, red welts with a central puncture mark surrounded by swelling. They often occur in clusters or lines, indicating multiple feeding attempts in one area. Bed bugs target exposed skin, such as the arms, neck, face, and legs, with bites frequently found around the neck, hands, and feet. The severity of the itching depends on the individual’s skin sensitivity. Some people may experience intense itching and even allergic reactions, while others might have mild or no reactions at all. If you notice clusters of red bumps that appear overnight, it’s worth investigating your surroundings for signs of bed bugs.How to Prevent Bed Bug Bites
