When I lost my Nuc earlier this year, I ditched the comb, with the larvae on them. I tried to squish any larvae rolling around on the floor (they move fast), but found them to be really tough and hard to squish. So, I swept them up and put them in the trash bag along with the comb. I'd sprayed everything with soapy water, first, hoping that would kill them. Not sure if it did.
I washed off the empty frames and put them in the freezer. I had one frame that had only been slimed on one side. That frame got rinsed with soapy water, rinsed with plain water, and stuck in the freezer.
I only had three frames to deal with, so they all fit.
I washed out the sides of the nuc, too. I still smell a hint of the slime when I use that nuc or the frames, but 3Reds says she can't smell anything. So maybe it's just in my head.
IMHO, if the bees are on your frames, then you are probably okay to let them start the clean up for you.
