I had some soil that was infested (stored outside) – 200F for 30 mins took care of it!

    I’d do the same to my soil but the smell is awful. I dream of having the kind of ventilation in my kitchen because I’d almost rather have fungus gnats.

    Looking at this gives me visceral flashbacks to the smell 🥲

    I use scalding hot water in my potting soil, as I mix it to pot plants. But I do remember the smell of oven pasteurization.

    I got one of those plug in lights with the sticky pad from Amazon. And not the really expensive one either, and all my gnats are gone!

    Fungus gnats only survive in overwatered soil… If you don’t overwater your plants then you won’t have a problem.

    Beneficial nematodes solved my fungus gnat problem.

    i just did this! i didn’t experience the smell though because i put foil on the top and secured it, then let it cool outside in a closed bin. i then added in some fertilizer and just mixed it around since baking it like that kills off a lot of good things too.

    I never thought to use the outdoor grill, brilliant!

    Can this be dangerous as soil can contain legionnaire’s disease? Would this kill it or permeate it? Concerned and curious…

  10. Just did this with my electric smoker a few days ago. The war wages on!

    Meanwhile neighbours: ‘The smoke rises from Isengard’

    Bonide or mosquito bits but if you want to avoid introducing them don’t buy bagged soil, mix your own inert materials and add the fertilizer with liquid.
