What should be done if a person has fleas? - in detail
If a person discovers fleas on their skin, the first step is to eliminate the insects from the body. Take a thorough shower using hot water and an anti‑lice or insect‑killing shampoo; scrub all hair, including facial hair, and rinse completely. After showering, change into clean clothing and place the worn garments directly into a washing machine on the hottest cycle the fabric tolerates, followed by a high‑heat dryer cycle.
The surrounding environment must be treated simultaneously. Vacuum carpets, upholstery, and floor cracks; discard the vacuum bag or clean the canister immediately. Wash all bedding, towels, and curtains in hot water and dry on high heat. Apply an EPA‑registered flea spray or powder to carpets, baseboards, and pet bedding, following label instructions for safety and re‑application intervals.
Medical intervention may be required if bites cause irritation or secondary infection. Over‑the‑counter antihistamines can reduce itching, while topical corticosteroids lessen inflammation. If the infestation persists, a physician can prescribe oral or topical insecticides specifically formulated for human use. Seek professional care if symptoms worsen or if there is a fever, as these may indicate an allergic reaction or infection.
Prevent future occurrences by maintaining personal and household hygiene. Bathe regularly, keep nails trimmed, and launder clothing after outdoor activities. For households with pets, treat animals with veterinarian‑approved flea control products, and regularly clean pet sleeping areas. Monitor for signs of re‑infestation and repeat environmental treatments as needed.
