The following chemicals have been used to control these pests. Be aware that some chemicals might not be safe for certain plants. Approved for greenhouse and interiorscape use: chlorpyrifos (Duraguard), diazonon, and resmethrin. +More Paul Kruse

From: Denis denis at skg.com> on 2000.04.03 at 22:02:06(4336) Fungus gnats are common in places that stay too moist and damp and have lots of decaying vegetable matter to feed their larvae. Your first course of action should be to remove the conditions that are allowing the critters to breed and thrive, improve santitation under benches etc. If this doesn't help then go to the heavy duty insecticides, Dursban etc. +More Paul Kruse wrote: > Fungus gnats not only feed on fungus, but the larvae may also feed on plant > roots or even enter plant stems. > The following chemicals have been used to control these pests.

From: "Bonaventure W Magrys" magrysbo at shu.edu> on 2000.04.06 at 01:47:24(4346) Thanks! I especially liked the one about the beneficial nematodes. Can they also "crowd out" the tuber infecting kind? My problem is I think that I placed a ~1" layer of cow manure at the bottom of the pot, then several inches of soil (very rich with other orgenic matter), depending on the size of the pot, the tuber, and more soil. This eliminates those pesky roots that come out of the drainage hole and wander around the drain dish, or worse dry up, or extremely bad - nothing worse than lifting a pot up off the ground after several days and finding that you have torn some roots off! The plants are very vigorous (3' high triphyllums and 4' high consanguineum and cons-types, and a taiwanensis built like granite) and the roots go down to the zone where they can feed and be comfortable but do not pass it (yet). So far I dont think I have gnat damage but always seeing 1 to 3 hovering around a pot and on the top of the medium advises caution and prudent action. I don't think I tried diazinon as a drench. Off to Home Depot!

From: Tim & Mary McNinch Newton at coiinc.com> on 2000.04.08 at 01:05:30(4351) For those who choose NOT to use chemicals for gnats... I live where winters will kill ALL so I must bring ALL my green living things inside if I plan on keeping any of them. During the winter of 1998/1999, I had the most pesky gnat problem and could not get rid of them for all the tea...bla, bla. (4"-6" due tomorrow night. Go figure?) Last fall, I brought ALL my plants indoors and promptly sprinkled the soil surfaces with cinnamon powder. I could count the gnats I had this last winter on one hand. Now there may have been other circumstances, but I know I used cinnamon. I am a believer. As for fungicide, I have used it now for 4-5 years and have warded off many problems with over winter storage of tubers. Tim McNinch +More No. IL, USDA Zone 4b

From: Skip Hanson <shanson at emc.com> on 2007.04.27 at 16:27:53(15602) All, Good morning. Does anyone out there have an opinion on whether fungus gnats are damaging or just a nuisance ? There seems to be conflicting information. They seem to be fairly easy to control but they never seem to go away totally and of course I can't see the larva so it's hard to tell how bad an infestation is.

From: Ryan Wachtl <ryanwachtl at sbcglobal.net> on 2007.04.28 at 23:17:01(15606) Skip, No argument here that these are definatley a nuisance. It is in my experience that fungus gnat larva can potentially damage the small root hairs on plants. They mostly feed on organic matter and this may include at times roots of the plants in the soil too. I have seen some heavy fungus gnat infections lead to an overall decline in plant health and vigor. These infections were also associated with elevated levels of soil water saturation and that can contribute to root - further fueling the infestation.
