Anyone notice any damage to their plants using a bti based product?
I have not found any negative refs but thought I should ask.
I'm fighting fungus gnat larva.

Bob, I wish you luck. I have tried a couple of different bti products. None
ever hurt the plants, problem is they never hurt the larva either. I cannot
believe I always got expired product, so I have to believe either the moss
pH is too low for bti growth or the mix is just too open and the bti washes
out.

Pat,

I tried the little circles for mosquito control. I used a piece in the water
I use for watering. I think it needs to be in the water a day or so to
multiply before you use it. I think they worked. Later tried some Bayer with
Imidacloprid, pretty sure it worked also but I don't like to use it. Have a
healthy Bladderwort plant (pinnincula or something
like that). It seems to keep them under control now.
