What to do if the whole body is covered with bed bug bites? - briefly
Clean the affected areas with mild soap and cool water, apply a topical antihistamine or corticosteroid to reduce itching, and contact a healthcare professional for evaluation and possible prescription treatment. Simultaneously arrange professional pest control to eradicate the infestation and prevent further exposure.

If the entire skin surface shows reactions to Cimex lectularius, begin with hygiene and symptom control. Wash the affected areas with lukewarm water and a mild, fragrance‑free cleanser to remove saliva residues that can prolong inflammation. Pat the skin dry; avoid rubbing, which may aggravate lesions.
Apply a cold compress for 10–15 minutes, several times a day, to lessen swelling and itching. Over‑the‑counter antihistamines (e.g., diphenhydramine, cetirizine) can be taken according to package directions to reduce histamine‑mediated itching. For persistent redness or welts, a low‑potency topical corticosteroid (hydrocortisone 1 %) may be spread thinly on the most inflamed spots; limit use to a few days to prevent skin thinning.
If lesions become painful, develop pus, or are accompanied by fever, seek medical evaluation promptly. A healthcare provider may prescribe stronger steroids, oral antihistamines, or antibiotics if secondary bacterial infection is suspected.
Simultaneously address the source of the infestation. Inspect bedding, mattress seams, headboards, and furniture for live insects, shed skins, or dark spots (fecal pellets). Isolate the sleeping area: encase the mattress and box spring in zippered covers, launder all linens in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, floorboards, and upholstery thoroughly; discard the vacuum bag or clean the canister immediately afterward.
Professional pest‑control treatment is often required. Heat remediation (raising room temperature to 50–60 °C for several hours) or targeted insecticide applications can eradicate hidden colonies. Follow the exterminator’s instructions regarding re‑entry times and post‑treatment cleaning.
Monitor the skin for several days after these measures. If itching persists beyond a week, if new bites appear, or if any systemic symptoms develop (e.g., dizziness, shortness of breath), return to a medical professional for further assessment.
