I am told by a plant pathologist that the imidocloprid in the Bayer products is NOT effective on mites. When I was starting out with brugs, I had a panic when I got Carmine Mites and Broad Mites. I stripped every single leaf from the plants, put them in a big plastic bag (actually 8 bags...HUGE bags) and then sprayed the bare branches down with Neem oil...really drenched them. Did this every 2 days for 4 applications. Burned the bags. It worked. New leaves came out and I just trimmed them back a bit.
