Fleas are wingless, blood-sucking insects that feeds on dog, cats, humans and other species.
Causes, incidence, and risk factors
Fleas prefer dog and cat hosts, but in the absence of a preferred host will use humans or other available animals as a host. Pet owners may not be bothered by fleas until their pet is away for an extended period of time and the fleas, in the absence of their normal host, begin to bite the owners. Bites frequently occur around the waist, ankles, armpits, and in the bend of the elbows and knees.
Treatment
The objective of treatment is to break the flea life cycle by treating the home, the pets, and the outside environment with insecticide . Home foggers and flea collars are not always effective. Birds and fish must be protected during spraying. If home treatments are ineffective, professional extermination may be needed. Calamine lotion helps relieve itching .
Expectations (prognosis)
Once fleas are established, eliminating them requires persistence. The problem will continue until the fleas are eliminated.
Complications
Secondary skin infection caused by scratching can develop after flea infestation.
Calling your health care provider
Apply home treatment and call your health care provider if there are signs of complications.
Prevention
Prevention may not be possible in all cases. Use of insecticides may be helpful if fleas are common in your area. Professional extermination may be necessary in some cases.
