Is potting soil sterile or devoid of bugs, eggs, etc?

srj19(4)April 2, 2014

I'd like to use something besides seed starting mix for some potted herbs at the office.

I brought a plant in the office that had been in the ground and within weeks the smallish insects became a problem.

I think a typical potting soil has been cooked or something to eliminate these little bugs, hasn't it? What do you guys use for an indoor plant that won't introduce bugs?

Thanks

Ideally, a potting soil should be sterile, but in reality is very susceptible to getting bugs, especially fungus gnats, while being stored. I don't know any way to avoid this. I have seen hints on cooking/bbqing your soil yourself to sterilize, but never needed too. For fungus gnats, I use little sticky traps, and keep control of my watering to not overwater.
