Rating
The claim that bed bug bites can develop into red, itchy, and swollen welts, quickly causing skin irritation at the bite site, is accurate. Bed bugs feed on human blood. Their bites are typically painless initially but can develop into red, swollen welts within a few hours or days. These welts are often intensely itchy and can cause significant skin irritation. The symptoms described are well-documented in medical literature, confirming the accuracy of this claim.
