You could potentially treat houseplants or other interior ornamental plants with Tempo SC Ultra as a foliar spray to help kill adult insects. If you have fungus gnats, they are usually caused by overwatering plants. Be sure to let the soil of your plants dry out to eliminate the harborage areas for these plants. If soil is compacted and very dense, consider repotting plants with severe infestations.
