Mosquito Dunks...These small round bits containing Bacillus thuringiensis subspecies Israelensis (BTI) can be sprinkled on top of the mix or container. The idea here is to knock out the fungus gnat larvae by introducing BTI into their feeding environment. When you water over the top of the bits, BTI is washed into the mix.
