Yes, using detergents or solvents with friction on surfaces treated with Precor 2000 Plus Premise Spray will reduce the residual on hard surfaces. We recommend vacuuming before treatment, and mopping before treatment if you are going to do so. You should retreat at 2 week intervals for active flea infestations.
