I wasn't suggesting to use chems!
That came out wrong...
I was rushed and meant to add that if you search vinegar mite spray you will find a recipe that will melt mites, you absolutely must wash it off after, it'll melt aphids mealies thrips too, and their eggs, but it's most effective against mites, their tough to impossible to eradicate.
It's alkaline and will burn ur plants if left on for more than 20-30 mins, but it works in a few mins do if u have a hose it's no prob.
I'd water first, wait 30-60 mins, in that time hand squish the the ones u see, then spray tge home made spray, watch it work, wait a few more mins then hose them down good!
High pressure bladt them if you and the plants can handle it...
I like to add rubbin alcohol to the recipe too, not a lot, an once or so for a gallon, maybe a half gallon.
