I've got another 5lb block of wax on top of the fridge in the mudroom 20 feet away. It was not affected. I've kept wax indoors with no issue till now. The difference being that I had this wax in the same container as I put my propolis scrapings in. I believe the wax moth eggs came in with the propolis; and everything was in the same cupboard.So what is the best way to store wax?
