It takes time and money to pasteurize potting mix

Don't you mean sterilize? Sterilized potting soil is readily
available and only a few pennies a pot more than unsterilized.
However still no guarantee a plant won't attract insects, so you'd
need to treat the plant... often misting with a mild soap solution
will delouse a potted plant.
