Fleas are small, wingless parasitic insects that have a hard, shiny
surface and travel by jumping. Flea bites usually cause only mild symptoms in
humans that can be relieved by home treatment measures, such as nonprescription
Signs and symptoms of flea bites may include:
Zigzag lines, especially on the feet and legs
and in the waist areas.
A single hive
Dull red spots that last even after other symptoms
Blisters or open sores in highly sensitive
Adult fleas may live in floor crevices, debris, and carpeting for
years and can survive for months without feeding. In rare cases, they can carry
disease, such as plague. Destroying household fleas (extermination) is an
important part of treatment.
