Ken, so I have two types of mites? Mites Kingdom here!
I will spray more often the plants with water to help them. I'm not keen to use something like dish soap or insecticidal soap just because we're in two different countries, I can't choose by brand and ingredients may not be the same. Sometimes I just can't find something similar to what you suggest.
Let's see what two days of rain and less heat will do.
Sue, sorry, I wasn't remembering we talked about soap so didn't think you could connect the things! My fault!
