The first instar is black with white spots. This is the second. They jump quite well, too fast to spat them mostly, thought they only jump twice before they run out of energy and you can get them.
Spraying with insecticidal soap seems to be helpful. And I think there are carnivorous wasps that eat them. When the wasp nests show up, the infestation thins out considerably.

Hey, we can just import a new species of parasitic wasps! What could possibly go wrong?
@EileenKCarpenter @celticsfanaticentomologist
Well.
Everything worked out well for the old lady who swallowed a fly.
@EileenKCarpenter @Shelter I'm sure the USDA's been working on that for at least a couple of years. It one of, if not THE, purpose of their job, i.e., to do all the science behind pest species.
@EileenKCarpenter @Shelter In Asia, their numbers are supposedly kept in check by natural parasitoid wasps (microhymenoptera).
