Find folders & subfolders containing only '.DS_Store'

Question

Through Terminal or otherwise, how can I find all subfolders in a folder/directory containing only the item ‘.DS_Store’?
I want to remove these.  I’ve tried deleting .DS_Store through different Terminal commands and then using Spotlight to find files containing zero (and less than 1) items and have located some, but not all.
Thank you!

I'm just keeping things factual, I'm sorry if you took it as a negative comment.  It is true that the OP wanted to remove (otherwise) empty folders.
So in my ~/Downloads/ folder, I do not want to leave all the folders there  I download files for work daily, and they are numerous in number and usually large.  I have a script which deletes files accessed over 60 days ago, and empty folders.  I have thousands of folders that have had their contents removed, but the directory is still cluttered.  Eventually you actually can run out of inodes on a disk, so it's fine to delete folders in this case.
This thread helped me figure out what I needed and it now works as I hoped. 
Script for reference:
#~/Library/LaunchAgents/com.myname.reaper.plist calls this script
#using launchd to run 1x a day at 10:00
#`
#!/bin/sh
# Finds all files within ~/Cases/ whose "last accessed"
# dates are more than 120 days ago and moves them to the trash.
# Finds all files within ~/Downloads/ whose "last accessed"
# dates are more than 60 days ago and moves them to the trash.

echo $TIME
find ~/Documents/Cases/ -atime +120 -print
find ~/Documents/Cases/ -empty -print
find ~/Downloads/ -atime +60 -print
find ~/Downloads/ -empty -print
find ~/Downloads/ -type f -name ".DS_Store" -print
find ~/Documents/Cases/ -atime +120 -exec mv {} ~/.Trash/ \; ;
find ~/Documents/Cases/ -empty -exec mv {} ~/.Trash/ \; ;
find ~/Downloads/ -atime +60 -exec mv {} ~/.Trash/ \; ;
find ~/Downloads/ -type f -name ".DS_Store" -exec mv {} ~/.Trash/ \; ;
find ~/Downloads/ -empty -exec mv {} ~/.Trash/ \; ;
