Therefore, applications must be timed for a stage of development when larvae are present in the soil. This versatile product can be used on a wide variety of ornamentals, as well as all bulb crops, bedding plants, and vegetable sets. It's a substance that's deadly to mosquito larvae (as well as larvae of blackflies, midges, and fungus gnats). They especially threaten seedlings and immature plants and can even cause massive plant death in severe infestations. Since I did this about two weeks ago, the number of gnats definitely appear to have lessened both at home and in the office.

In fact, Bti is used in mass quantities by cities and municipalities worldwide to control mosquito populations. I put a fresh set of yellow sticky traps over each plant to see how effective the treatment will be.t. to species of several invertebrate taxa (Acarina, Nematoda, Collembola, Annelida, Hymenoptera) inhabiting the soil has been demonstrated, but only rarely is it possible to relate dosage information to field situations, and in many cases the B. Gnatrol WDG is listed by the Organic Materials Review Institute (OMRI) for use in organic production. 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. Gnatrol WDG Biological OMRI certified Larvicide gnat control gives you the power to eliminate fungus gnat larvae and protect your plants' health. I have been misting less frequently in an attempt to dry out the top substrate, and am wondering if that caused the springtails to move deeper into wetter substrate.

Gnatrol WDG Biological Larvicide is OMRI certified Larvicide gnat control contains bacillus thuringiensis, a soil-dwelling bacterium that targets gnat larvae and kills them before they cause plant damage.My first instinct after writing about this plant so many months ago was to toss the plant in the trash, but I felt that would be conceding victory to the gnats. You will be killing all of you beneficial microbes if you do, which will severely stunt your plants growth.
