Gotta agree with Allen on this one. It seems to take no time for the girls to find any exposed honey or propolis, but if you put it directly in the hive, you run the risk of exposing them to much more than they're ready to take on. From what I've seen so far (with my limited experience) if you put it pretty much ANYWHERE they can find it, they'll clear it out without having to worry about encouraging other hives to rob them, or risking giving them more than they can handle. After a good long freeze, I'd just set it out for them to clean out themselves. Then if anything of the wax is salvageable, melt it down. If not, clean the frames thoroughly before considering reuse.
