Is this a Mealybug and if so, how do I kill the little ***?

This is a new plant? Acquired at a show, online or a shop? If at a show, were all the plants from the same vendor?

If the plants are from the same vendor, yeah, take precautions. If the plants are from different vendors, I'd kill the F'er and isolate the one plant, quarantine the rest. Certainly be vigilant on all plants but I'd wait on the thermonuclear stuff.

I don't know the life cycle but I doubt the mealy hooked up with another mealy, deposit eggs, hatch and infest other plants in a day. I've never seen them on the move but I think they are crawlers, not jumpers.

Edit to add: I've had new plants arrive with a mealy on occasion (from reputable vendors). I'd kill the F'er, isolate for a few weeks but have never suffered a repeat. I'm vigilant, I have loups and magnifying glasses for regular inspections.
