First, determine what you are actually inspecting for and when you find what you are looking for, close it all back up as carefully as you can. Im not real sure, but Im assuming you are doing a frame by frame inspection each time you go in. (Im assuming and we all know what happens when you do that

) You can determine real quick if you have a queen-when you see larvae or capped brood you know shes there. Stores can be determined by just hefting the hive up without opening the hive.
