Hi @Hallamt99 - I wonder if the tablets you’re talking about are made of camphor? I guess something like that would be helpful, if residue & scent doesnt bother bees. I freeze all my extra frames, even if they only have a little wax on them, and then if I can’t keep them in there because I need the space I put them in sealed plastic trash bags and store them in my shed. The initial freezing kills any eggs & after that the plastic keeps just about any critter out. Plus I don’t think the moths are out and about here in winter, too cold unless they’re inside a living hive.
