Ok I will call theseFungus Gnats but I don’t think they are. I have very few fliers (less than 5 aweek, and my yellow strips are always empty), no larva in the soil at all, No larva on slices of potatoes put on the soil. The fliers look a lot like the fruit flies you get in the kitchen when your fruit starts to get old. All my plants look fine but here is what Iam dealing with. I’m my soil plants, after I water if there is water in the catch try ( less then a shot glass worth) sometimes I can get 100 larva overnight. They are not washing out of the soil; I watered into a container to check. These larva are Microscopic. You can’t see them at all with the naked eye and there hard to see with a 40Xglass. They are gray. I wash the trays out and put soap in them to kill the next ones. Soil is not a problem. Hydro is a problem. The other night I looked in my res and found 100’s of them in a 1000PPM fret solution with 50ml 3% H202 per gallon, they were all alive and happy J the plant looks fine. They are not on the roots that I can find and they are only on the surface of the water. So my question if they are Gnats (am I sure they are but not sure what kind) what can I put in my rez to keep them from coming back that will not hurt the plant? A drop of soap? Any ideas would help. I can’t post a pic without a USB microscope and I don’t have one.
I have looked allover the Net and cannot find them. I have read a lot of books that have picturesof Fungus Gnats and Root Aphides and they are not them.
Any ideas will help
