I used B.T. - Bacilus Thurengensus (may have spell wrong) anyways I mixed this into my water as a soil drench and eliminate fungus gnats quite easily.
if you read what is in gnat nix or mosquito bits I believe it's the B.T. that does the work. I think it also sells as Monterey. Anyways. I'm not the best at IPM but when I find something that works I try to pass it on.
hey! thanks for stopping by, yes i am trying some mosquito dunks atm. i have used Gnatrol and wasn't convinced... but after a couple of recommendations i thought i should try a different source of B.T.
also using nematodes from time to time and trying to keep at it with both. seems to be working atm - the problem for me is that there are always gnats around to re-infect so i am just trying to use it as prevention now rather than cure.
