About this deal
Because fungus gnats thrive in moist conditions, especially where there is an abundance of decaying vegetation and fungi, avoid overwatering and provide good drainage. Allow the surface of container soil to dry between waterings. Clean up standing water, and eliminate any plumbing or irrigation system leaks. Moist and decomposing grass clippings, compost, organic fertilizers, and mulches are also favorite breeding spots. Avoid using incompletely-composted organic matter in potting media unless it is pasteurized first, because it will often be infested with fungus gnats. Improve the drainage of the potting mix (e.g., increase the proportion of perlite or sand in the mix). Minimize organic debris around buildings and crops. Avoid fertilizing with excessive amounts of manure, blood meal, or similar organic materials. Screen and caulk leaky windows and doors to help prevent pests from coming indoors. When bringing any new houseplant home, keep it in a different room from your other plants for at least a few weeks while ascertaining if it conceals unwelcome visitors. Once you’ve spotted insects on a plant, remove that container a safe distance away from your other plants.

The first symptom of damage that you’ll notice is wilting and a general decline in the health of the plant. Read on to find out how to kill fungus gnats with simple DIY remedies. How to Control Fungus Gnats
Buying Guide for the Best Gnat Traps
If fungus gnats start to emerge after you’ve brought your houseplants inside, you will need to use one method to kill the larvae and one method to catch flying adult fungus gnats. Once the larvae hatch from their eggs, they will feed on the plant roots, damaging them and making them more susceptible to disease. In less than two weeks, they emerge from the soil as adults and start the cycle over again. Allow the surface of peat-based composts to dry out a little before watering the plant again. Remove dying leaves and dead flowers regularly, so that they do not begin to decay and so attract fungus gnats. Adults are less likely to lay eggs on dry surfaces with no decaying plant tissue for the newly hatched maggots to feed on. Covering the compost with grit or pebbles can help.
How To Make A Fungus Gnat Trap At Home - Gardening Know How
If Bti or nematodes aren’t available and high populations are intolerable, pyrethrins or a pyrethroid insecticide may provide temporary, fast-acting control. Spray the surface of potting soil and plant parts where adults typically rest. Do not aerially fog indoors or attempt to spray adult gnats in flight. Be sure the product is labeled for your particular use (e.g., for "house plants") and read and follow the product's directions. RELATED: Solved! What Your Plant’s Yellow Leaves Mean and How to Fix Them STEP 1: Make a homemade gnat trap. Several natural enemies help to manage fungus gnat populations in outdoor systems, such as landscapes and gardens, and indoors in greenhouses and conservatories, including the predatory hunter flies, Coenosia spp. These flies catch and consume adult fungus gnats in mid-air, and prey on fungus gnat larvae in soil while developing as larvae themselves. Conserve these and other natural enemies by avoiding broad-spectrum insecticide applications. Table 1. Commercially Available Biological Pesticides and Natural Enemies for Controlling Fungus Gnat Larvae.
The only modest noticeable results of attempting to drown the larvae was after a full 24 hour soak in water. A rough guesstimate is that around 50% had drowned. The other half were motionless, but started to revive shortly afterward. If you are opposed to harsher treatments, one excellent product to use is Mosquito Bits. Mosquito bits are basically corn cob granules which are coated in BTI bacteria (Bacillus thuringiensis subspecies israelensis). Let houseplant soil dry out to a depth of 2 inches before watering. Fungus gnats like to lay their eggs in damp, overwatered soil, and their larvae usually inhabit the top few inches of topsoil. This makes them especially prolific during winter when gardeners continue their usual summer watering routine. Don’t let soil dry out completely, however, or you might end up killing your plants in the process. Pouring water into the trays in which seedlings or houseplants are nestled and allowing hydration to be absorbed through the plant containers’ lower drip holes, is another way to keep the top layer of soil dry. This method is called bottom watering.
