Are those little black flies floating around your plants? Chances are they're fungus gnats. The larvae live in the potting soil and cause the most damage there. And it's precisely those larvae that you can target.
The best time to take action is from February to October . During these months, the larvae are active in the soil, especially on houseplants, cuttings, and in greenhouses. Using nematodes against fungus gnats , you can target the larvae before they develop into flies.
Because fungus gnats reproduce rapidly, starting early is the best strategy. So don't wait until it gets out of hand.
👉 In short: use nematodes against fungus gnats as soon as you see flies, preferably during the growing season between February and October.
