I dont think you just want to get any soil, to whatever store you go to, if you see any of these grab them youll be good. Foxfarm ocean forest(organic) Light warrior(very good for germination) Black gold( this is organic and a premium blend of potting soil. Ive never heard of anyone getting these soils with bugs or anything, if you go to places like home depot or stores like lowes where they leave their gardening soils out in the open with holes from tossing the bags and rain entering the soil you will prob get bugs
