Does Avid work on fungus gnats?

If not what is a good pesticide/insecticide to get rid of fungus gnats?

Answer:

Avid 0.15 EC Miticide Insecticide is not labeled to treat fungus gnats. 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. It is completely safe to spray on ornamentals. In the garage area, spray as crack and crevice and focus on damp areas/reducing the water/moisture. 

If you have containerized plants, be sure they are not over-watered and that the soil is allowed to drain properly.
