About this deal

But after reading more about it, Bti is as close to a miracle fix as modern science has come up with.

Important: Gnatrol WDG should not be injected in combinations with fertilizers or fungicides containing copper or chlorine, as this may neutralize the active ingredients. The product is now available in a water-dispersible granule (WDG) formulation that leaves no residue and is easier to measure, ensuring increased application accuracy. Because the larvae attack the roots, the plants cannot obtain the nutrients that are needed to grow and will start to wilt. DO NOT apply soil drenches to plants under stress or follow applications with excessive amounts of water. The adult flies feed on fungus but they lay eggs in soil and the resulting larvae feed on plant roots.Gnatrol WDG Biological Larvicide provides fungus gnat control on indoor ornamentals and plantscapes. Once the gnat larvae ingest the active ingredient, they become paralyzed and stop feeding; the larvae usually die within 24 hours. Gnatrol WDG Biological Larvicide 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.

While they do a great job of trapping adults they don't seem to be stopping new larvae (remember that it just take one gnat to get through the perimeter alive to lay 200-300 eggs). Here's the cool thing about it--because humans, animals, birds, and fish have acidic and not alkaline digestive tracts, the Bti toxins don't have any effect on us. Use Gnatrol WDG Biological Larvicide in greenhouses where protection against fungus gnat larvae is necessary. You will be killing all of you beneficial microbes if you do, which will severely stunt your plants growth. A LD50 study (by definition is going to kill half the test animals) is not an appropriate indicator for health effects if a normal dosage is expected.I think what kept the plant fighting was putting it in the bag, where it got ample humidity (something that ferns need). Gnatrol® SC is a biological insecticide for use on protected ornamentals for the control of larvae of fungus gnats. I introduced a few new plants and the gnats must have hitched a ride because soon I had an infestation and it was getting progressively worse. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . oz per 100 gallons for light infestations, and 13 to 26 oz per 100 gallons for heavy infestations, applied as a soil drench.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift.These spores and crystals must be ingested by the immature feeding stage of development (larval) of insects to be effective .

Although adult fungus gnats are a nuisance to people, they don't damage plants or bite humans or animals. I still see and squash one or two gnats every few days, but the problem seems to be a lot more under control. However, since all ornamental plant species have not been evaluated, sensitivity to Gnatrol WDG should be checked on several plants prior to wide scale usage.

I know I had springtails in there when I first set up the tank earlier in the year, but don't see them anymore. You'll find that most of us here are very conservative when it comes to risk to frogs, so even a link to harm is enough of a red light. Note: BTi is considered not harmful against humans and children, and is widely considered the organic choice to control fungus gnats. Plants are easily replaceable, and fungus gnats are easily controlled (if not eradicated) in other ways (physical evacuation, vinegar trap). They especially threaten seedlings and immature plants and can even cause massive plant death in severe infestations.
