Pet shops and pharmacies generally sell drugs to remove parasites (such as fleas and lice). Rub it on your body and cover it with a towel for ten minutes to ensure that the bugs die. Then let it lie down when it has nothing to catch fleas, bathe it often and disinfect its nest often. Burn your clothes, sheets, etc. Use hot water, or the bugs won't die, and the kennel can be replaced with a new one.
