Talstar P and Tempo SC Ultra are very good products for gnat control. The biggest difference between them is that they have two different active ingredients. They are both great insecticides and can be alternated so that there is no pest resistance built up. Be sure to inspect the lawn for any ways to control moisture build-up such as eliminating standing water and trimming trees and shrubs to allow moist soil to dry.
