Fleas bite humans and often target both the legs and feet. Flea bites are extremely itchy and uncomfortable. They appear as red spots surrounded by reddened circles.
If you are bitten by a flea, wash the bite, and apply an antiseptic and an icepack. Try to resist the urge to scratch, and consult with a pharmacist for lotions or antihistamines that can treat the itch.
As fleas can infest the entire bodies of domestic house pets, consult with a veterinarian for treatment solutions. Bathing pets with specially formulated shampoos and cold water helps control infestation and inflammation. Steroid creams and antihistamines are options for treating pets as well.
