When I inherited the greenhouse attendant position at the Fort Worth Botanic Garden the plants were infested with mealybugs. They were trying to do IPM there as well so I tried several sprayings of Neem Oil (had I known about the mealybug predators I would have tried them too). But, alas, the Neem Oil was a waste of time so I resorted to a systemic treatment with Imidacloprid. It worked quite well, maybe not the most environmental solution but the plants were finally happy to be relieved of their long infestation.
I thought this was going to be about spiders (we occasionally get small hunting spiders in the indoor light garden).
A neem oil/horticultural soap mix and/or drench does a pretty good job cleaning up mealybugs.
