gnats???

well i left my plant for about a week and when i came back every thing was fine exepct i have gnats all arond my plant. i havent seen them touch my plant yet but could they pose a problem to my grow?

sticky paper

neem oil

pyruveate (sp?)

those all help =] and yeah, they harm the roots in the soil...

do they burrow in the soil?

Look at the FAQ about fungus gnats. I recently used predator nematoads to get rid of the larva and eggs that attach to the root system. Diatomatious earth helps also.

Fungus Gnats:

Signs of an infestation:
Fungus Gnats are attracted to soils that are rich in compost and nutrients. They lay eggs on the surface, hatching into larvae. Those larvae feed on the root tissue, including root hairs, and the outer cell covering of the root; often leaving only the central tube of the root. External signs include discolored leaves, and systemic plant failure. Fungus gnat adults will often run across the medium and may fly if the plant is shaken.

Controlling Fungus Gnats:
Pyrethrum aerosols, as well as placing yellow sticky traps all around the plant will help control the emerging adults. Gnatrol (containing natural Bt) is highly recommended.
