Hello, I'm here to say I've given wrong information in the past. *I've said before that I used my Orthene 75 SP for spider mites... * Well, in a recent attack of these guys on my banana tree I've tried to kill them with repeated attacks of my sprayer. * (I've use this before and it worked.) *But guess what. *They couldn't have gone away because of my spray. *Here is why... * Since I've done multiple applications and they are still there I decided to read the mixture book.. * No where in there does it say "spider mites" *so. *There you go. *Orthene 75 SP. is not for spider mites. *Although excellent for Thripes, Scale, and other bugs.
