Spotted lantern fly infestation

I saw a ton of these on my outdoor plants this morning. I had a few last summer but this is ridiculous. I can't see any damage to the stems - at least not yet - but I am very worried. I can kill one here and there but there's just too many of them to make a difference. If anyone knows what kind of damage they are capable of and what to do about it I would be eternally gratefull! Here are some photos...

Where are you located?
Have same issue, I use a vacuum.

I'm in the lower Hudson Valley in New York. I just put sticky yellow cards throughout the growing area, but a vacuum sounds brilliant! I will definitely try that. Do more keep coming back after vacuuming or does the population seem to be limited?

What do they do to the plant? At least its not caterpillars

Last year I used neem oil and dawn and think that combo hurt the plants more than the lantern flies.
This year I am just trying the vacuum. going to pick up a new tip tonight using a clear hose to get them.
Last year they just went away in September. They were still about the grapes but when the cannabis was flowering they were gone.

I don't know what damage they do and yes they aren't caterpillars or hemp borers (more of an end of season issue) but I don't want them on my plants! I only saw a few last year and didn't bother with them and nothing bad happened. But they are proliferating and I know they are a problem with the hops plant. Got this back from a google search: "Hops (Humulus lupulus) and hemp (Cannabis sativa) are closely related plants belonging to the same family, Cannabaceae." That worries me. I got mixed results when I searched if lantern flies are attracted to yellow sticky cards but I'm giving it a try. But thanks to your great advice I am looking forward to sucking the bastards up with my hand vac!

when i first seen them i was thinking the same thing, however with pests just landing and hanging out on a plant can spread plant pathogens.
