I ask this because many of the Pyriproxyfen (the prime ingredient) studies via Google scholar, while talking about the sterilization of male/females adults also refer to the feces being contaminated, as such when other fleas consume it they themselves are sterilized. So would it better to wait 2 - 7 days? or just vacuum every day?
We always recommend vacuuming every day during flea treatments. Not only does this suck up the dead adults and any feces left behind, but the heat and vibrations of the vacuum help stimulate the eggs to hatch and be exposed to the product you are using. The fleas are protected inside their eggs much like a chicken egg and until broken or hatched, nothing can affect whats inside. By forcing the fleas to hatch you help control the infestation faster as they are being pulled onto a surface that has a residual insecticide of your choice and the IGR waiting on them. Please let us know if you have any other questions.
