If you don't want to screw around get the predatory mites for your specific mite at the above link. If you don't know what mite it is buy the mix of predatory mites. 1 bottle should be plenty for your grow and they will destroy whatever mite ails you. And lady bugs are fine indoor I have yet to use an indoor predator that left the room it was in or caused any problems for me.
