  Re: [Aroid-l] Spider Mites

Michael is right, they supposedly don't do well if you raise the
humidity. I had little luck with that approach, however. If your friend
thinks they like Amorphs then he should get a Typhonium venosum and
stick it in the corner. They will all go to that corner!

Common wisdom with the two-spotted spider mite is to spray with 2 or 3
different miticides according to the label directions but *rotate* the
chemicals used. Spider mites develop immunity quickly because of their
short breeding cycle. I had reasonably good results on my Ty. venosums
last year when I rotated Kelthane and an Ortho product called "Systemic
Insect Killer" with active ingredients Acephate and Fenbutin-oxide (the
label says "Formerly Isotox" but I don't think Isotox had the same
ingredients). The Ortho product is VERY smelly! Ugh.

He might also try spraying those infested plants with Messenger a couple
of days after the miticide. At the very least it won't hurt them and it
may give them a boost.
