Using Riptide with the Talstar P will give you a fast knockdown and then the 30 day residual. Spray Talstar P and Riptide on trees, shrubs and bushes paying special attention to the underside of the leaves. You can also spray your lawn to help control the low flying gnats that tend to land there. Talstar P will give a long lasting residual while the Riptide will give you a fast knockdown. You can use both products in the same area to get both a fast knock down and a long lasting residual. It is best to treat in the early morning or the late evening when these pests are most active.
