Not the brown ones - though Periplanata can hibernate and the eggs of all of them can survive UK winter temperatures - but not -18C for weeks.>I'd even got sufficiently desparate to consider overwintering in Finland (temperatures there should put paid to them).
You can put them in a freezer for years and they will be fine when defrozen, unfortunately.
Hence the choice of Finland (and family there to keep an eye on the boat).
