Flea bites go away on their own and normally do not require treatment, according to Healthline. Anti-itch creams available over the counter help to alleviate the itching. Oral antihistamines are helpful as well.
MedlinePlus explains that scratching flea bites can cause infection. Healthline advises patients to seek medical attention if a white pocket or rash develops in the area of a flea bite.
To prevent flea bites, fleas must be eradicated from the premises, states Healthline. This involves treating pets for flea infestations and treating the entire home with pesticides. Do-it-yourself treatments, such as foggers, are sometimes effective, but professional pest control treatment may be required.
