Flea itself belongs to a tiny insect, which is mainly parasitic on the roots of human hair and the surface of skin. Its main way of life is to suck human blood. If you want to get rid of fleas, it is suggested that you can scrape off the hair on the affected area first, and then apply sulfur ointment and Stemona tincture cream on the itchy skin or suspected flea infection, which has a good insecticidal effect.
It should be noted that fleas can spread through indirect contact. Close-fitting clothes, sheets, quilts and towels need to be scalded with boiling water, or put on new towels to avoid repeated contact with the source of infection and cause repeated attacks of diseases.
Symptoms such as itching, erythema and papules may appear on the body surface before the fleas are completely eliminated. Some anti-allergic drugs can be taken orally, or hydrocortisone butyrate cream and desonide cream can be used externally to relieve symptoms.
