Been getting questions on fungus gnats which are small fly-like insects that may be noticed flying around houseplants. They are commonly associated with over-watered houseplants or those grown in poorly drained potting mixes. If a houseplant pot is harboring fungus gnats, treat the soil with insecticidal soap. Another management approach is to cut back on water so the soil dries out between watering. Any larva present in the soil will dry out and lack of water will reduce fungal growth, reducing the food supply for adult fungus gnats. A third option is a combination of letting the soil dry between watering and then watering with a solution of water and insecticidal soap. Transplant the houseplants early this spring in a potting medium (do not use garden soil).
