hmmmm tricky... There was someone on here a while back looking to own one of these - try a forum search on here perhaps you'll get lucky!!
Presumably this will be a continuous problem though unless you can separate the adults? I'll bet there's pet related forums that cover this sort of thing and can offer better advice on egg control. Try a goodle groups search or something maybe?
Good luck in solving youe dilemma!! Just whatever you do don't release them into the wild and pass such advice on along with any snail you can rehome!
