I've been trying both 209 and 217. They just aren't working for me. The mites just come back and back and back. The cost of this stuff is just too high for the results I've seen.
I've used it half a dozen times and also the systemic 209 in the water. I don't understand how everyone else has had good results. 3 days after any spray mites are back full force. I mean I douse the whole friggin plants, container and soil as well as the walls and floor with horrible results...
