By heating you will kill all bugs, weed seeds, fungus spores and bacteria.
However have you ever looked at freshly tilled garden soil. While it has
plenty of creatures in it not all are bad. We do not live in a sterile world!

Hello All,

I kinda do the same thing with potting soil and my home made compost. I
went to the dollar store, picked up a few large aluminum roasting pans,
covered and threw them in the oven until the temp reached 185 deg F. So far, so
good.

I bake commercial potting mix in an oven at 220 deg F (roughly 105 deg C)
for 2~3 hours to kill fungus gnats & their eggs.
