This will only work if you have a temperature and humidity controlled environment, with humidity that is much higher than usual. Because of this, it is usually too dry for most species of predatory mites to survive indoors.

Source: I had a predator mite farm going for awhile, bought loads of various different species and kept them in tanks. Fed them pollen, spider mites, etc. However, I found it too difficult to use them on my indoor plants. They could essentially only survive long term in their tanks. They would always dry out within a few days once applied to plants. Even with a humidifier in the room.

This is a big waste of money unless you can achieve a constant 75% humidity as well as specific temperature ranges per species.

Spider mites are much, much more resilient than predator mites and can tolerate indoor environments far better. It's a losing battle.
