It may be hard to tell if you have bed bug bites or bites from another insect. Being aware of bed bug symptoms is the first place to start when diagnosing a bed bug problem. In general, bed bug bites will be red and generally have a darker red spot in the center. Bed bug bites can cause a very irritating itch. They will often form into a rash, made up of many small or raised bumps. These bumps will often appear in a line or as a cluster of dots—this is because bed bugs tend to feed multiple times at the same location. Bed bug bites are also usually found on exposed parts of the body like the arms, legs, hands, neck and face.
Some of the first symptoms of bed bugs are blood spots on the bed, sheets and pillow case. Another telltale bed bug symptom is small black dots on sheets that resemble black pepper. This is bed bug poop. While they know how to hide, bed bugs may be seen moving about on the bed and other furniture between about 2 to 4 a.m. They may not be obvious to the eye at first, but you can spot the bed bugs through inspection. Bed bugs are flat are resemble a small dark apple seed.
Another bed bugs symptom may be that sleeping partners have completely different reactions to the bed bug bites. For example, one sleeping partner may have no reaction at all while the other may have an allergic reaction including hives, blisters or severe itching.
A doctor should be seen if you have had an allergic reaction or intense skin reaction to bed bug bites. Bed bug extermination is needed to eradicate a bed bug infestation (bed bugs will not leave on their own accord!)
