Attract Natural Gnat Eaters

There are many natural predators that eat fungus gnats.

The most popular and effective one is a bacterium microbe known as bacillus thuringiensis, AKA Bt.

This microbe is deposited directly into the soil where gnats are present and will disturb their lifecycle. Depending on where you buy it from, the process is different.

But generally, youll want to apply Bt on a cloudy day. Youll mix the Bt solution with water and then spray the solution or use a watering can.

Some Bt products may have you using an injector or syringe requiring a dilution rate. They come in a sealed container to preserve their efficacy are usually found online or in specialty nurseries. Use as directed.

Bt is harmless for beneficial bugs but very deadly for pests like gnats, caterpillars, and worms.

You should avoid using Bt when possible as its an extreme measure in my opinion. But if you just cant kill the fungus gnats, then you can consider using nematodes as a last resort.
