When you run Wakelock Detector it will show you the awake percentage (in red) in the status bar at the top of the screen. Then, you'll see the top apps, in descending order (highest up top), of the apps using CPU and presumably only the ones using a wake lock [edit: I tested that with one of my apps that I can control whether or not it uses wake locks and that is true].
So, the top of the list that WLD presents to you is a good place to start with your candidates, again, bearing in-mind that wake locks are not "bad" but are a tool used by apps to keep some resource (like the CPU) alive and kicking so that it can do things like syncing in the background, etc. [Gmail, Facebook, etc.].
Temporarily uninstalling a top offending user app and then observing how or if the battery is now draining might tell you if that app was indeed consuming more resources than you would like.
