Bed bug bites typically appear as small, red, itchy bumps on the skin. These bites are usually clustered together or arranged in a straight or zigzag pattern. Each bite often has a small dark spot in the center, which is the puncture wound where the bed bug fed.
The area around the bite may become swollen, red, and itchy, and in some cases, blisters or hives can form, especially if there is an allergic reaction.
While some people may not have any reaction to bed bug bites, most individuals will develop visible symptoms within one to two days after being bitten. The bites can sometimes take up to two weeks to heal and might be mistaken for other insect bites, such as those from mosquitoes or fleas.
If you notice signs or symptoms of bed bug bites, it's important to consult a healthcare provider, especially if you're unsure of the cause or if the reaction worsens. Over-the-counter antihistamines or corticosteroid creams may help relieve itching and swelling, but it's best to avoid self-medication and get professional advice, particularly if the bites become infected or the symptoms worsen.
