Definition of Fleas
Fleas are blood-sucking insects that feed on humans, dog, cats, and other animals. Fleas do not have wings.
Causes, incidence, and risk factors
Fleas prefer to live on dogs and cats, but may also be found on humans and other available animals.
Signs and tests
No testing is necessary.
Treatment
The goal of treatment is to get rid of the fleas by treating the home, pets, and outside areas with insecticide. Small children should not be in the home when insecticides are being used. Birds and fish must be protected during spraying. Home foggers and flea collars do not always work. If home treatments do not work, professional extermination may be needed.
Expectations (prognosis)
Getting rid of fleas can be difficult and takes persistence.
