In the window with all the other inside trees I have a Hong Kong orchid and a baobab, both of which did just fine all summer outdoors but now are suffering from some kind of bugs. There are no webs, so they aren't spider mites, but there are little white dots smaller that a grain of salt, mostly on the under sides of the leaves. Every day or so there are lots of little black dots over the Hong Kong orchid buds and now on the new leaves on the baobab. I spray but they seem to come back. Am I missing the gestation cycle? It won't be time to move them outside for maybe two months, so I need to do something now.
