Fleas are an insect that are wingless, with mouthparts adapted for piercing skin and sucking blood. Fleas are external parasites, living off the blood of mammals, and yes humans.
For humans: Fleas can settle in a person’s hair in less than ten minutes, causing soreness and itching. The itching associated with flea bites can be treated with anti-itch creams, usually antihistamines or hydrocortisone. Calamine lotion has been shown to be effective for itching. For Pets: Flea and tick repellant powder being applied to a dog.
Treatment: Besides treatment of fleas on the pet, insecticide applications are required indoors and, frequently, to selected areas outdoors. No people or pets are to be on the premises during treatment to your home or until all spray residues have dried. All flea areas should be treated, including carpets, other floor areas, pet resting areas, and upholstered furniture.
