I've had limited success with waxmoth prevention and would like to share my
method. I haven't used excluders until this year so I've had some brood in
my honey supers to attract wax moths. After extracting each super is
wrapped up in a plastic trash bag and stored in the freezer for a few days
to kill any waxmoth eggs in them. After that they are simply stored in my
garage still in the plastic trash bag. The secret (I think) is that I keep
a bug zapper in the garage. It's on all the time and kills any flys,
mosquitos and MOTHS that get into it. This keeps the flying insects in the
house to a minimum. I've noticed dead moths under it. I believe I'm
killing them with the bug zapper before they can get into my comb. The
reason I call this limited success is because I've only used it for two
years. When it's been ten years without a problem I'll label it a success.
This is probably only useful for the smaller beekeepers out there. A
commercial operation would need a walk in freezer that wouldn't be used the
rest of the year. My freezer doubles as food storage for my household.
