Well as the little girls wud say OMFG! I have just discovered another use for bacteria. BTI, bacteria blah blah, lol, to long to remmeber but it is the stuff in gnatrol or the hella cheaper mosquito dunks for 10 dollars at lowes. This stuff is a bacteria that is manufactured and organic to kill fungus gnats! It gets into the soil and without harming the plants at all it kills all the larvae of the fungus gnats.
I have read some wicked results with this and also how versatile it is. Just take a cake of the stuff and dun it in water and then let it sit overnight. Take that water and use it as a soil drench. Or topdress with the broken cakes, just use a little or use as much it supposedly is harmless and water in. Shud kill all. I cannot get rid of these little cocksuckers! I hate them. Damn, do I hate them.
From rr pucks to my flower girls they are an infestation. BTI!
