We tried this on two plants, and presumably because we used composted soil our larvae had plenty of other organic matter to feed on and weren’t interested in the potato slices. Seedlings fail to thrive. The strength of hydrogen peroxide is also important. The only modest noticeable results of attempting to drown the larvae was after a full 24 hour soak in water. Some have suggested turning the top few inches of soil and adding circulating fans to dry the soil surface out faster. Try to keep the topsoil dry, clean standing water and don’t leave the saucers filled with water.

Their host plants include Easter lilies, pepper, alfalfa, wheat, geraniums, clover, soybeans, cucumber, carnations, potatoes, lettuce, and corn. If you suspect mold or fungus, replace the pot liner, the soil, or both. Shake the jug well and let the granules soak for around 6 hours. Any changes made to the biological makeup of a plant’s soil, such as cinnamon to inhibit fungi or hydrogen peroxide (which can kill beneficial bacteria) should include a plan to restore these elements by incorporating a sterilized compost back into the plant’s soil. Fungus gnats are typically between one-16th to one-eighth of an inch long—so they're pretty darn tiny, and often misidentified as fruit flies. are the most common houseplant pest, and are distinguished from Fruit flies (Drosophila spp.) A female gnat will deposit up to 40 eggs at a time on the surface of moist soil, near decaying organic matter, or hidden closer to the stem of a plant. However, Neem oil doesn’t directly kill bugs. They are an especially serious problem for small carnivorous plants.

They’re very small bugs that are attracted to sweet smells and dampness. This may help somewhat along with other measures, especially for larger planters (1 gallon size) where the soil depth is greater than 10 inches if you can control how much water the plants receive so that the surface soil stays fairly dry. This might be a good option before or after you’ve gotten your infestation problem under control, but it really won’t help in getting rid of the problem if there are already eggs or larvae in the soil or if drainage holes in pots are still accessible to adult gnats.
