Fungas gnats. To kill the adults get a spray with pyrethrins (made from chrysanthemum flowers) and cover the soil with it. Fox Farm "Don't Bug Me" is an example. Using yellow sticky strips close to the soil can also catch hundreds of adults and helps the cause. Next, drench the soil on the next few waterings with a BTi solution (eg. Gnatrol). That kills the larvae eventually. Expect to fight them for at least a week or two this way. BTi is Bacillus thuringiensis isrealensis that is also in mosquito "dunks" and some other mosquito killer formulations. Good luck.

thx snake for the info.i just got the yellow strips to catch them

they usually are in the soil to begin with. i always used plenty of sticky traps in my grow room and over a short period of time those adults that didn't die off on their own got caught in the traps. personally i know nothing about pesticides because i've never had to use any.

they live in soil the best way to get rid of them is to dry out ur soil, and water only when plants are showing stress and i mean this by when u c the leaves no longer pointing upward but rather starting to dropp then water do this for a week in combination with the yellow strips and a spray to the underside of leaves in the dark cycle with " end all " used on tomato plants and ull b kool

Just put a thin layer of kids play sand on top of your dirt and be done with it,they wont hang around since sand is not a happy place for fungus gnats to breed simple as that.

anyone else done this?

I hate the gnats and I have them too. Would be interested in the sand if it worked because I don't like using pyrethrins (allergic).

The sand works they wont lay eggs in sand and it wont hurt your plants.Dosent have to be much either just a thin layer those gnats lay eggs that make larvae that eat decomposing material "aka"your soil no soil exposed no eggs,no larvae,no gnats.I know it seems to simple to work but it does,after the adults that have already hatched die out or are trapped there will be no gnats.

i had a gnat problem a few weeks ago, i used hydrogen peroxide, which i diluted more with water on the soil, let the soil remain dryer longer than normal, and had a few ladybugs around my plants for a few days, I'm not sure if the ladybugs helped, but doing those things i went from have lots of gnats to none at all in about a week.
