In Zone 8b near Austin. I am being absolutely decimated by red spider mites. I can't get a handle on them. Tried Neem and Pyrethrins.... Nothing!!! Keeping up with the hatch cycle, but they don't seem to be giving in! Nicotine spray seems to be the next step, but the stuff is so dang toxic! I live rural, have predators, but they are starting to be effected by the neem... Catch 22!!
