mosquito dunks

Anyone here have experience using these, I have ticks on my roots and some flies. The flies i can kill off but wanna take care of the larvae growin down under too.

yeah, I had some jumpy lil bugs in my dwc buckets, mosquito dunks would hold them off. It did seem to effect the ppm levels, that kind of sucked.

I used them recently, along with sticky traps, for fungus gnats. It really knocked them down, but they did start coming back. I'm going to try higher doses (2 or 3 dunks in my water barrel).

Thanks for the responses.
