KrautFabrik started grow question 4 years ago
I have a fly invasion with about 100 or 200 of them :neutral_face: (last to picture)
At first i though they are Spider mites, but i cant find any eggs.
Can someone tell me what they are and give me advice?

Hey Big KF ! so sorry bro, in english these are called fungus gnats. they are a pest, and they lay eggs in the soil. there are a few remedies, some are chemical some are organic, but of course not very much works except biological warfare. So it's gonna be a three step process. first get some Steinernema feltiae which are nematodes which are microscopic worms that destroy eggs and contaminate the flies and make them sterile. simply buy some of that and follow the instructions on the packet for "outbreak" not "prevention". Second, get sticky strip, a lot of sticky strips... spend like 20 bucks on them, and put them up all over, including over the soil, at different heights here and there, and ... everywhere sticky strips... finally, get some sand and make a top layer on your soil to prevent re contamination. as final things, increase the air circulation, and never wear outside clothes in the grow room or near the grow room. Hope this helps ! :rocket:
