I just bought this stuff (on Amazon) to use on my indoor China Doll tree that has survived many infestations. I'd only been using diluted rubbing alcohol to kill spider mites with, but my poor tree got eaten as soon as it regrew small branches. So far, all I have done is mix the stuff and spray it on, which I did outside and in the evening (AZ sun is unforgiving here). It doesn't smell all that bad, not what I had expected. I will write a follow-up in a week or so. Really hoping this does the trick; China Doll plants are hard to come by here and are my favorite houseplant! Right off the bat (or right out the box), I removed a star, due to the "peel here" instructions on the back that do not include instructions (I peeled the label off, there was no 2nd layer to peel).
