Well submerging the pot underwater. i suppose it's messy, but would kill anything there. I'm not sure for how long? 10 minutes would not hurt the plant, as long as the soil drains well. I use DE food grade in a dust pump. Coffee ground deter ants too, not as well. Also borax traps are not that toxic, the common commercial ant trap. You can make you own with Borax detergent too. I had a recipe somewhere?
It would not hurt to add 1/2 cup hydrogen peroxide to a gallon of water and water the plant. It will kill fungus gnats, and eggs. Those are all the less toxic methods I know of, and they work to some extent.
My peppers are still producing like mad, so they are not ready yet!
