I have always thought it good policy to replace frames back into same hives. If I do not extract and replace same day I usually put the stickies into a freezer for 48 hours and then store in supers marked with hive number and ensure flat on a board (so no ants etc can get in) and an open insect mesh lid on top. I have had very little or no wax moth trouble. In saying this, if you are short of frames and need to get some back quickly, if you have had an AFB test and are confident you have no other diseases in your apiary then you could interchange some frames, but try and avoid.
