DO NOT DO WHAT I DO.. without doing your own research, talking to others, and then assuming 100% responsibility if anything goes wrong.. That said.. Fungas gnats in soil.. very easy.. very inexpensive.. for almost 3 decades this has worked every time. Mix some standard 3% h202 (hydrogen peroxide) and water (I dunno, a cup a gallon won't hurt a thing).... Water your plants... yup.. there is going to be foam. The H202 does NOT harm your soil (I,ll assume you are not organic, and even then), (farmers use h202 in their water in some regions as it helps in the increase of nutrients and provides oxygen to roots in compact or overwatered situations)and your roots quickly repair (you have little creatures destroying them anyway as we speak). Wont hurt a thing (worse than it already is.. this is a remedy, not a regular maintenance program).. EXCEPT it will kill EVERY fungas gnat larve in the pot.. BUT... you need to hang a strip, or get some vinegar or empty beer or someting to attract the living ones.. they will go right back to that soil and start laying eggs again... get a spray bottle with hydrogen solution and spray and stir top soil for a few days and let the flying gnats die off. In 'MY' (not to be confused with anyone elses) experience, the plant responds almost immediately.. they really do seem to like that dose of extra 0xygen and they just look so much better and there are no more gnats. Anyway.. it's cheap.. it's effective.. It's natural..it works.. don't over do it. Good luck.
