They spread to damn near everything on my property, I hit pot plants with spray all season and kept them at bay, but they are now on all our Lilly, Marigold, and strawberry around the property. Seem to be leaving the fruit trees alone but they are still around. Hopefully the cold winter will kill everything outside. I will continue to treat my moms indoors with Kontos and biowar to keep them safe until then.
I would try some swirskii mites as predators and try to build up a natural population. Im going in with some other local growers on a monthly order to use as preventative maintenance in my garden through out the year..
