Can Bed Bug Bites Reappear

Bed bug rashes and bites may reoccur as long as the infestation remains in the home.

Do bed bug bites get worse over time?

Over time, bites get worse. When adult bed bugs bite, they inject more anticoagulant. And, over the course of several exposures to this anticoagulant, the allergic reaction increases. Bites that start out as tiny dots that can become painful, itchy, swollen welts.

Why does my bug bite keep coming back?

The bumps can reappear because of new insect bites and stings, or continued environmental insect exposure. Sometimes secondary infections appear because of scratching. Scratching the itchy bumps and blisters can break open the skin. That increases your risk for infection.
