killing indoor spider mites what works?
insecticidal soap does not work. Pyrethrums require me to hit them square on, or they survive. There is no residual effect with pyrethrums. These are small cacti under a lamp. (it hasn't spread to my large plants.)

There are some decent Miticides, look up Avid and check out the label. Not sure about the use on Cactus. Also might want to look at Neem Oil or Azatrol.
