Delete folders/subfolders after processing?

Hello.
I have a folder where students drop their projects (photography). They typically drop in a folder containing two sub-folders — one subfolder contains .doc files and the other contains .jpg files. Right now I have Hazel going through the folder (and subs) and moving the .doc and .jpg files to another folder, but I'm looking for a way to "clean up" (ie. delete) these empty folders once processed. Is this possible?
Ideally, they would be deleted immediately after processing, but I'd also be happy if these could be deleted after a set time has expired — say, 1 day or something like that — since they're just empty folders at that point.
Any help would be appreciated.
Thanks,
Kristin.
