For the last several years I've had a problem with root mealybugs in my containers (I'm 99% sure that's what it is - there are white deposits on the plant roots and around the edges of the containers). I disposed of some affected plants and watered others that I didn't want to lose with insecticide, which I don't like doing but it didn't seem like I had any other option. However they are still present, and I'm wondering if anyone can give me advice, as there doesn't seem to be that much information out there (it seems to be another pest brought in from the tropics, from what I can gather). Is the only thing I can really do to dispose of all my plants? Also what is best to do with affected compost? Will the bugs and their eggs be killed by composting in a bin? Or is it safe to put it on open ground and they will be killed over the winter?
