Conserve is labeled for shoreflies but not fungus gnats. Decathlon is labeled for control of adult fungus gnat so Decathlon by itself should be effective. The Conserve may be used for spider mites and is also very effective at controlling thrips. Some other suggestions for fungus gnat control would be Citation, Talstar, or Duraguard but there are many other chemicals labeled. Consult our Poinsettia Federal Insect Control Chart (260K PDF) for a complete list. Thanks!
