I had a colony last year that was a small swarm capture which was going really well, it had built out 4 frames of comb from scratch. During the first couple of months I was feeding with an entrance feeder. Good brood pattern with ample stores. I stopped feeding thinking they were set to fend for themselves during summer. Summer here there is a total fire ban so if someone smells smoke the fire brigade will be called, and rightly so, so inspections were less frequent as I'd have liked. One day I noticed the entrance was quiet so I did a smokeless inspection and found no bees in the hive and wax moth silks binding the frames together. Empty! There were a few bees emerging from cells tongues out, some pollen but no honey stores at all. At the time I blamed the moth and they became enemy number one. (Come to think of it they are the only enemy over here...)
In reflection I think the bees had absconded in search of greener pastures not because of the moth but because food was not available. I had thought if they were bringing pollen, which they were, they must also be collecting nectar which I now know is not the case. They may also have been robbed over time due to the use of an entrance feeder.
The wax moth just did what they are here to do, decompose.
Having said all that I could be wrong.... I frequently am....
