We hate gnats, and here's why! Fungus gnats are completely normal if you have plants indoors, but beyond being a nuisance, they can actually harm your plants! The adult gnats thrive in moist soil, where they lay their eggs. When the larvae hatch, they feed off of the roots of the plant, which can cause harm to the health of your plant. Luckily, there is a natural product that is 100% safe for you and your pets, but is deadly to the gnat larvae.
The key ingredient is BTI (Bacillus thurigiensis israelensis). This natural ingredient is lethal to the larvae and can help control the gnat population in the soil with consistent use.
If you have a few plants: Sprinkle a small amount of "bits" onto your soil before watering. When you water, make sure to saturate the bits and allow them to dissolve into the soil. If you see the gnats reappear, simply repeat the process again.
If you have many plants: Add 4 tablespoons to 1 gallon of water, allowing about 10 minutes for the "bits" to dissolve in the water. Scoop off any remaining pieces, mixing to make sure the BTI is well incorporated into the water. Water your plants with the mixture and repeat the process once a week for 3-4 weeks.
