Riptide 5.0% Pyrethrin ULV is a mosquito control product designed for applications in residential misting systems if you have a 30-55 gallon drum with nozzles on your home, or you can mix it in a standard tank sprayer alone or with a residual insecticide to treat bushes and surfaces where mosquitoes or insects may be present. There would not be a reason to spray a patio with this product.
