When spider mites show up I am dead serious about stopping them as quickly as possible so my mix is a bit strong but it works. Per gallon of water I use between 1 and 2 tsps of Dawn dish washing liquid depending on how much webbing is already under the leaves, 3/4 cup to one cup of food grade DE ( mix with water and strain before adding to tank) and 1 to 2 tablespoons of 10% Permethrin.
This mix will pretty much kill any insects whether good or bad. I also use it when I get a bid infestation of aphids, stinkbugs or leaf footed bugs. Usually spider mites don't show up here before mid to late summer when the weather gets really dry. If I see a small infestation starting earlier in the season I will sometimes use Neem oil and see if it will stop them before they get bad. If it doesn't I pull out the big guns because once you let them get too far along it is really difficult to stop them.
