Does anyone use/add beneficial Insects/ Organisms?

I've tried several times to introduce predatory mites to my indoor growing space to kill off spider mites, which are a constant problem for me in every season. I honestly haven't seen any positive effects, and the live mites are expensive. I am still tempted to try this again because it seems so easy--they do all the work, and I just sit back and let it happen! I have no idea why they don't seem to be doing anything. Either way, they don't seem to linger, so that doesn't seem to be an issue.

I've never heard of predatory mites so I may just need to give it a shot myself. Thanks!
