Can Mosquito Dunks Kill Fungus Gnats and Fruit Flies?
This is a question I am hoping to answer via some experimentation in the near future. Some may recall that I tested out the nematode, Steinernema feltiae, as a fungus gnat killer last year and found that it was reasonably effective. The problem was that it was a fairly expensive solution, and generally would require ongoing applications in order to keep the gnats at bay over the long haul. Incidentally, I also tested Steinernema against fruit fly larvae, but I discovered one of the other limitations of this biocontrol organism – that being heat intolerance (at least I am pretty sure that’s what the main issue was). And if those limitations aren’t enough – perhaps I should remind you of the fact that Red Worms have been shown to kill these nematodes as well!
