Bed Bugs Symptoms, Causes and Treatments. The most common bed bug symptoms are small red bumps or welts that resemble mosquito bites. There are often multiple bites in one area and they are sometimes formed in rows. The rows are due to resting an arm on a mattress seam or other area where the insects are hiding. Bites can occur on any area of the body.
Bites on the skin are a poor indicator of a bed bug infestation. Bed bug bites can look like bites from other insects (such as mosquitoes or chiggers), rashes (such as eczema or fungal infections), or even hives. Some people do not react to bed bug bites at all.
