You probably have Menards in your area, they have Promix under a roof.
I avoid buying potting mix that has been sitting outdoor and received rain, I could be wrong about this, but a lot of brands have breathing holes in the bag, maybe that allows them to lay eggs in it.
MiracleGrow is synonymous with fungus gnats, you should expect it whenever you buy their potting mix.
