Shell from Grayville, Illinois writes,
How long after dog is dipped in Permethrin solution can it be given a regular bath?
It is recommended to wait two weeks after the treatment of Permethrin SFR 36.8% to bathe your dog or you will simply remove the insecticide. Permethrin can be reapplied every two weeks if needed so we would recommend that you bathe your dog prior to the Permethrin SFR 36.8%.
