For possible encouragement- I took about a dozen plants to my workplace in late fall. Some weeks later, I realized that one (Yautia, an elephant ear type) was going completely spotty with mites under the leaves. I took that home, cut off all the leaves (OK for me if it went dormant) and also scraped away surface soil and discarded. So far none of the other plants at work are showing any mites. None of the home plants either which is pretty unusual- I have had them many winters.
KNOCK ON WOOD
I've been trying to hold back mealybugs on an Agalonema with 50 50 alcohol, and only partial success- will try the soap.
