DO NOT apply soil drenches to plants under stress or follow applications with excessive amounts of water. In my case, the gnatrol was effective and I would recommend it if you are experiencing gnat infestations. Trial of Bacillus thuringiensis israelensis, a mosquito larvicide, against Porcellionides pruinosus, a terrestrial isopod (2005) -- " Woodlice, Porcellionides pruinosus, were not killed when exposed to granular Bacillus thuringiensis israelensis. Regular follow-up applications using the suggested light infestations rates, will establish a long-term maintenance program.

After ingestion it breaks down the intestinal walls and the larvae stop feeding and die within 24-72 hours. Chlorine levels in potable water supplies should not present a problem with Gnatrol WDG performance).

And these were LD50 studies that used high doses purposely to determine mortality and damaging health effects. UConn info on Bt -- " Bt bacteria are one-celled organisms that reproduce asexually through spores creating crystal proteins as it does. They're fine little bugs -- annoying, but completely harmless -- and I'm trying to be less of a speciesist about bugs.

EPA Memorandum: Review of ecological non-target insect studies for Bacillus thuringiensis Cry3Bb1 protein. I read threads that mentioned gnats as a temporary nuisance but I wonder if that is because dart frogs will eat them! I put a fresh set of yellow sticky traps over each plant to see how effective the treatment will be. Easier to prevent an infestation with lower, preventative doses than to try and knock it down once you're over run by gnats. Because the larvae attack the roots, the plants cannot obtain the nutrients that are needed to grow and will start to wilt.The infestation for that had gotten so bad that I enclosed it into two sandwich bag, partially to serve as a greenhouse, but partially because there were so many gnats coming out of this plant it was clear that the roots were thoroughly infested.

This effective, naturally occurring larvicide kills damaging gnat larvae in less than a day and brings infestation levels under control. My hope is that eventually I'll go weeks without seeing one gnat, and then I'll finally be able to properly repot and fertilize this plant and hopefully see it grow again. Gnatrol WDG is listed by the Organic Materials Review Institute (OMRI) for use in organic production. Important: Gnatrol WDG should not be injected in combinations with fertilizers or fungicides containing copper or chlorine, as this may neutralize the active ingredients. These are also common factors of wilted plants and may not necessarily indicate a larval infestation.Gnatrol WDG Biological Larvicide is a highly selective, biological larvicide for use in greenhouses to control fungus gnat larvae.

I have read on this board that gnats are common in the first few weeks of a new tank and that they will go away on their own eventually. Gnatrol is now available in a water dispersible granule (WDG) formulation that will not leave a residue and is easier to measure for increased application accuracy.In fact, Bti is used in mass quantities by cities and municipalities worldwide to control mosquito populations. Note: BTi is considered not harmful against humans and children, and is widely considered the organic choice to control fungus gnats. Over the course of the following few weeks I added plants and seeded with dwarf white isopods and springtails.
