agree that fuzzy bees looking competitive/angry over one pot of honey would be enough for me. Did I mention the fuzzy? Fuzzy. It's just that the jar looks like a honey jar. It screams "I'M HONEY!!!!" except for the fact that it says wax.
If you just had one of the bees with a word bubble saying, "Mind your own!" i think people would get it a lot easier. I don't mind that the honey has been transferred to saying wax, because the point of the pun makes it more symbolic than what is actually in the jars. Nice work all around with the concept, positioning and fuzzy buzzies. A different shirt color to contrast the yellow would be nice.
