K here's how it went.
Brake Cleaner killed most of them, they seemed to be literally frozen on the spot.
But today I went again for the cleanup and a few of them survived, they were busy on the nest, maybe 10 or so of them... I guess those were behind cover and the cleaner didn't take them.
So I sprayed em again, killed a few more but mostly they ran away instead of attacking. I scraped the nest and burned it, just for good measure. Then I removed the little plastic container and threw away the corpses.
