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.

Talstar P (Talstar One) is a great product to use for fungus gnat control. It is to be used inside and outside the home, but will only kill the adults as the larvae is protected in its egg form much like a chicken egg is protected until cracked. To control the larvae you would need to mix the NyGuard IGR (birth control) in with the Talstar. NyGuard is labeled for fungus gnats as well as a large variety of other insects to sterilize the adults from being able to lay viable larvae. This will control the population drastically in keeping new ones from developing. You should mix 1 ounce of Talstar P with 4 ml of NyGuard IGR to each gallon of water you use. Talstar P can be used as a broadcast over the entire lawn or just as a perimeter treatment. You will want to focus on the mulch bed area and the underside of shrubs, bushes, or trees in the area.
