How to Get Rid of Fungus Gnats in Houseplants with Home Remedies

Gnat Control

Fungus gnats are mostly minor house pests but they can become a bigger nuisance if you don’t treat them quickly. Here are our top suggestions for getting rid of fungus gnats in houseplants using home remedies.

1. Trap the Fungus Gnats with Vinegar

One of the easiest home remedies to eliminating fungus gnats is by setting up an apple cider vinegar trap, which consists of vinegar, dish soap, and water. First, mix together equal parts water and apple cider vinegar then add in a few drops of liquid dish soap. Next, pour the vinegar solution into a disposable bowl and set it aside next to the infested houseplants. You should see plenty of dead flies in the bowl the next day. The traps are also available for purchase.

2. Place Yellow Sticky Traps Around the Plants

In addition to setting up the apple cider vinegar trap, we also suggest placing a few yellow sticky traps around the space where the fungus gnats are frequently sighted. Some of these sticky traps are also designed to be plugged into the houseplant soil for added convenience.

3. Keep to a Consistent Watering Schedule

Fungus gnats are more likely to appear if you over-water the houseplants because they seek moist soil conditions. Make sure to only water the houseplant soil when the top inch of the soil layer starts to feel dry. You should never see standing water in the plant container. If you already have a serious fungus gnat problem then it may be best to replace the soil in the houseplant. Make sure to only purchase high-quality soil.

4. Consider Using Mosquito Dunks

Mosquito dunk is a biological control product that may also help remove fungus gnat problems. Mosquito dunks contain a bacterium that may get rid of the fungus gnat larvae in the soil. Just add a bit of the granules into the houseplant soil and give it some time for the effects to kick in.

5. Sprinkle Cinnamon Powder on the Plant Soil

Cinnamon could also be a natural remedy for curbing fungus gnat infestations. Cinnamon powder is a natural fungicide so it can get rid of the fungus that the gnat larvae feed on.
