First of all, there is no need to panic. Don’t try to solve the problem on your own. While there are many excellent products on the market, some may not be suitable for your pet—this is especially true for cats. Ask your veterinarian for help. They are trained professionals who can help you select the right product.

Understand that these products do not completely repel fleas or kill fleas instantly. It often can take from several hours to a couple of days to kill newly acquired fleas. That is shy a combination of preventive fleas treatment aimed at eliminating early flea stages, along with adulticides that target adult fleas are often recommended to pet owners.

Consider your environment. If your home becomes heavily infested with fleas you may need to treat the premises. Your veterinarian can advise you as to the best course of action, which often will include thorough and repeated vacuuming of the carpet, weekly washing of pet bedding, and the possible application by yourself or a licensed professional of insecticides and insect growth regulators on your carpet. Outdoor treatments of shaded pet resting areas are rarely necessary.

Remember: Do not miss a dose or application and always give products according to the label directions. All animals in a household must be on flea control, even if they spend all their time indoors!
