Answer: If you've got a problem with fungus gnats, there are several ways to control your current problem naturally;
Fungus gnats love moist conditions so you should avoid overwatering and provide good drainage. Clean up free-standing water and eliminate any plumbing or irrigation system leaks. Moist and decomposing grass clippings, compost, organic fertilizers, and mulches are favorite breeding spots.
Beneficial nematodes ("Steinernema feltiae")can provide relatively long-term control of fungus gnat larvae and they can be self-reproducing after several initial applications to establish their populations. These nematodes can be applied through an ordinary sprayer or sprinkling can.
Bacillus Thuringiensis israelensis (sold as Gnatrol) is effective only on larvae, but if you kill the larvae you will be controlling future populations.
Hope this information provides the natural solutions to help you elimnate your gnat problems.
