So the Neem took the leaves too? Dern! That's what the soap is doing too. The very next day (from first treatment) I went out and filled the sprayer with good clean water and overdose of superthrive to try and save what leaves I could. I really blasted them good. I also did it the next morning. It did seem to minimize the damage. What I'm going to hate is the next round. Especially on my Emerald Frost, whose grown for her leaves anyway. Sorry to hear you lost the plant, that's terrible.
Funny you had problem with them Carol, being so humid there. Like I said, mine were an unwanted 'gift,' I've never ever had a spidermite issue before this.
