They’re in S NH now.
Not sure why there’s such a push to have the public kill them. It’s like gypsies, japanese beetles, EAB, etc…once they arrive they’re there for good.
A lot of reports from further south are that they go wild for a few years and then the numbers drop off quite a bit. Not sure if that’s a case of other insects and animals learning that they’re tasty or if there’s some other factor at play.
The continents will all be back together again in 250M years so we may as well mix all of the insects around the planet together now.
