Depending on the mix ratio used and how heavily you sprayed, it could be anywhere from just as the product has has had time to dry, or several hours after application before the smell of the Permethrin SFR completely goes away. If the odor is objectionable, then you may want to consider switching to a water-based insecticide, rather than an oil-based one.
