I am using demon WP. I want to know if mopping up the white residue it left behind after drying will make the poison lose its effect.
Yes, Demon Wp does have the potential to leave a slight powdery residue. If you should mop the treated areas it will lower efficacy of the active ingredient. We recommend at least waiting a week to two weeks before mopping.
