Water From The Bottom @thestemuk
To reduce fungus gnat populations, it is important to reduce the moisture at the top of the soil where fungus gnats breed. Watering should be done from the bottom using a dish filled with water, allowing the roots to draw up water as needed. This prevents fungus gnats from growing in moist soil at the surface and helps keep them away from your houseplants.
Cinnamon Powder @margretaville
luckily there is an inexpensive, easy way to keep fungus gnats away: use cinnamon powder around the plants. Sprinkling a thin layer of cinnamon powder around the base of your house plants can help deter fungus gnats before they even arrive. With just one simple step, you can protect your home while keeping your plants fungus-free!
Lightweight Expanded Clay Aggregate (LECA) @ABCAustralia
there is a simple solution to eliminating fungus gnat infestations in your houseplants; replace the soil with Lightweight Expanded Clay Aggregate (LECA). LECA is an inert and porous material that is both lightweight and durable, making it ideal for planting container crops. Plus, it won't harbor fungus gnats the way traditional soil does. So if fungus gnats have been making your houseplants their home, try swapping out the soil for LECA to get rid of them once and for all.
Replace Soil with Water @modernbotanicalshop
By far the most effective solution for fungus gnat infestations is to replace the soil in the infected planter with water. This technique works by displacing the fungus gnat larvae that are easily able to survive suspended in perlite, coir, and soil particles. Additionally, the lack of organic material will cut off their food source leaving fungus gnats nowhere to lay eggs. To successfully replace soil with water, remove any existing substrate from your planter, rinse it out carefully, then fill halfway with clean filtered water. Finally, add aquatic or hydrophytic plants suited for that environment as permanent replacements. After few weeks fungus gnats should be eliminated and you will have a thriving aquatic ecosystem inside your home!
Replace Soil with New Soil @chillypho
Fungus gnats in house plants can become an annoying problem, but there are ways to combat them effectively. If fungus gnats are found in house plants, the best remedy is to replace the old soil with fresh, uninfected soil. The fungus gnats lay their eggs in the top few inches of soil, so removing this contaminated layer and replacing it is necessary to avoid larvae development. For plants that remain indoors, fungus gnats can be a recurring problem. Following this removal procedure is the best prevention method for eliminating fungus gnats from house plants.
Water, Dish Soap, Clove Oil Solution @liveholistic
To combat fungus gnats, many serious plant lovers recommend a simple water, dish soap, and clove oil solution. Simply mix all three ingredients together in the recommended proportions and then either pour directly onto the soil of your plants or spray with a hand-held mister. This simple solution is effective at killing fungus gnats and can safely be used on both indoor and outdoor plants when applied properly.
Carnivorous Plants @tannertheplanter
One popular method of controlling fungus gnats is to use carnivorous plants to kill them. Carnivorous plants absorb water using their specialized leaves, which fungus gnats are naturally drawn to so they can lay eggs near a source of water. When fungus gnats collect on the carnivorous plant leaves, the leaves clamp together and trap the fungus gnats, killing them within a few days. If you have fungus gnat issues but don't want to use chemical insecticides, then carnivorous plants may be the perfect solution for you!
