I'd say most do re-use them as you've mentioned and that's fine to do. The bottles mentioned above are also good and keep the fragrant aroma
at bay when not in the woods. I found some new things this year that are small circular containers, about 1.5" in diameter and 1" deep that have tops that latch securely and small spring clips attached to utilize when hanging from a branch. They are very handy and seem to keep the scent(s) fresh.
If you won't be hunting for several days, I'd also recommend placing the wicks you mentioned in a sealed baggie and then in the freezer to keep them as fresh as possible. I don't think the wife has noticed (yet) the fresh buck hock glands now in the freezer here.
