Bed Bug Bites Pictures, Symptoms: What Do Bed Bug Bites Look Like …

Bed bugs feed on the blood of humans and other mammals in order to grow and thrive. Bed bugs use a variety of biological signals, including body heat and carbon dioxide emitted from warm-blooded sources, to identify a host.

You may notice a single bite, while other times several bites will appear in a line. (1) “In most cases, they occur in clusters or zigzags of flat, itchy bites,” Durham says. “One bedbug will usually take more than one bite, so the severity of your infestation can have a big impact on the severity of your physical reaction to the bites.”

The difference in the bites is that scabies don’t actually bite. They burrow. When the skin first reacts to the scabies, it can develop red, itchy welts that may look a lot like bed bug bites. Over time, the welts caused by scabies appear more scaly and leave slight, raised trails in your skin. A rash caused by scabies can feel more intensely itchy at night, which can mislead people to believe they are bed bug bites. Scabies should be diagnosed and treated by a physician.

Bed bug bites affect everyone differently. Some people may experience more severe symptoms, including allergic reactions, while others may have no reaction at all.

At first, you probably won’t feel anything. As noted by the CDC, when a bed bug bites, it injects an anesthetic and an anticoagulant into your bloodstream. As a result, you may not realize you’ve been bitten until the telltale red welts appear hours or days afterward. When that happens, bed bug bites can become itchy and irritating. If you scratch at these bites, they may become even itchier and more irritating. Excessive scratching can create skin problems, bleeding, or a secondary infection.

In most cases, the only way to say for sure whether it was a bedbug that bit you is to search for evidence of bedbugs living in your home. “Once you start to notice the itchy bites, the second giveaway is the presence of small blood spots on your sheets or mattress, usually resembling patches of rust,” Durham says. Those spots are left behind after a bedbug has been smashed.
