Re the spider mite predators-if you're thinking of getting the predatory mites, they cannot maintain living in temps over 90 degrees. Also, one company shipped two spotted spider mites for the predatory mites to eat while they were shipped to me in less than 24 hours. Half the days here are over 95 degrees F. for two months. Predatory mites a waste of money. Two spotteds love temps 95 and over, and dry. They don't like humidity. What are the preventative things to do to not get them? I think they lay dormant in one of my rooms that was a grow room, and in the bathroom, where I keep males for seeding chosen female.
