Fungus gnats can be a nuisance in any home, particularly for those with indoor plants. These tiny black flies thrive in damp and organic-rich soil, making potted plants their preferred breeding ground. To effectively eliminate fungus gnats, start by allowing the top layer of soil to dry out between waterings, as gnats are drawn to moist environments. Consider replacing the top layer of soil with coarse sand or gravel, which can deter adult gnats from laying their eggs.

Next, introduce beneficial nematodes, microscopic worms that seek out and destroy gnat larvae in the soil. Alternatively, you can use sticky traps placed near your plants to catch adult gnats and reduce their population. If the infestation persists, a diluted solution of hydrogen peroxide can be applied to the soil; this not only kills larvae but also helps to oxygenate the soil.

In addition, ensure your plants are not overwatered and that pots have proper drainage to minimise standing water. By implementing these methods, you can regain control of your indoor garden and bid farewell to those pesky fungus gnats.
