However, pre-existing flea populations may continue to develop and emerge after treatment with PROGRAM 6 Month Injectable for Cats
• Program® is a once-a-month oral treatment which effectively sterilizes the female by preventing eggs from hatching. Data shows that within seven days after lufenuron is fed to the animal, virtually 100% of the eggs laid by female fleas failed to hatch. If you use Program®, all cats and dogs in a household must be treated because any untreated animals can infest your household with fleas. If you already have a flea infestation, lufenuron will break the flea life cycle, but, for a period of time, adult fleas will still bite your pet because it does not kill adult fleas.
Program does not kill adult fleas. The product works by preventing the development of flea larvae. If cats have a high level of flea infestation at the start of the treatment, it is necessary to apply a product that is recommended for use against adult fleas during the first one or two months, or longer depending on the environmental challenge.

Program Flea Control for Cats | EntirelyPets
After a treatment with Program, the cat’s body synthesizes the drug and it is secreted along with the natural oils produced by his skin; thesubstance makes the flea eggs sterile. It might take a few weeks for a full treatment.Today’s products used as flea treatment for cats, like Advantage, Frontline and Program, have pretty much replaced many of the previously popular products. However they are still produced in the shape of shampoos, sprays and powders for treatment and prevention of fleas. New flea products are far more effective and they are also safer than conventional insecticides. As an added bonus, they are easier to manage.Cats are fastidious and many dislike having smelly topical products applied to the fur. But until now, there have not been many alternative products that cats can take orally to treat fleas, except the over-the-counter products, Capstar and Program. These treatments have limitations: treats adult fleas, but the effect does not last beyond 24 hours. While works for 30 days to prevent the development of flea eggs, it does not kill adult fleas. Hence, for maximum effectiveness these two products should be used together. Cat owners will be happy to know they now have another option in Comfortis.A 2002 study published by the Journal of the Egyptian Society of Parasitology, showed this. Dogs and cats in a flea-introduced environment were given Program flea control on a monthly basis and at the doses recommended by the Novartis Company (the doses that the Program flea control packet recommends). By the end of the study (day 91 after the Program flea treatment was first given), adult flea populations were observed to be absent to 'very low'. It should be said that the environment that was used in this study possibly didn't have a well-established flea population (i.e. an environment full of long-lasting flea cocoons) prior to the study starting. In environments with a heavy flea burden already present, adult fleas will continue to hatch from cocoons for up to a year or more and so, although the Program flea control will be most effective at stopping these newly emerged fleas from laying viable eggs, you will still keep seeing the odd adult flea running across your pet for many months (until all the cocoons already present in the carpet have hatched out or dessicated).
