One of our users, @aliciajeannn, asks “I keep getting gnats in my soil indoors. I water my plants less. I repot them. I have spray. I have tried soap and apple cider vinegar but no matter what I do they come back when I water my plants. What should I do!?”

@aliciajeannn has tried it all! Luckily, the GrowIt! community responded with some great ideas to get rid of the more stubborn gnats.

According to @pinders_nursery, “Sounds like you are dealing with fungus gnats. their eggs are in the soil. when moist, they hatch and larvae eat your plant’s roots. The MOST important thing is to grow DRY. Remove saucers. Soap and ACV alter soil pH, and soap increases the ability of the soil to hold water -making matters worse. The fact is, a good container potting mix is designed to provide an optimum growing environment, and repotting may be advisable. Be sure to assess the condition of roots. But if you want to try to salvage what you have, you might want to try a drench of 1 part H202 (hydrogen peroxide) 3% and 4 parts water.”

“Spread some cinnamon powder on top of the soil every now and then.” @sflgardener adds.

@katdlouhy says, There is a commercially available bacteria called Bacillus thuringiensis I (Bti) that solves the gnat and fly problem selectively. It is the active ingredient in those mosquito dunks & granules.
