wax moth destruction

First and second year beekeepers! You may be pulling honey supers, extracting, and have empty drawn comb. Or maybe a hive failed leaving you with drawn comb. Drawn comb is gold! You can always buy more bees, catch a swarm, make a split, or otherwise replace bees. But drawn comb can not be purchased. Having drawn comb exponentially increases a colony’s productivity versus starting on foundation. A spring package on drawn comb typically makes honey the same year.

Beekeepers must protect their drawn comb from wax moths which will take every opportunity to destroy your bee’s legacy.

Here are a few excerpts from an email I sent discussing protecting drawn comb:

<begin>

Be thankful they are on plastic foundation. Otherwise you often have to replace the foundation. And if they are in wooden frames wax moths will actually bore holes in the wood as well. On plastic you can scrape it off and re-coat with wax for next year.

As for the freezer: You can Google wax moth, life cycle, etc and find some research. It’s like anything else, dependent on temperature and length of time of exposure. Two days may be sufficient IF your freezer is at 0 degrees F. If your freezer is kept at 10 degrees F it may take 6 days. And if at 20 degrees F it may take 14 days. (These are guesses but you get the idea.)

There is a temperature range for wax moth reproduction. When the temperatures get cool enough outside they are no longer a threat. I guess there are some people with a limited number of frames who can store them in the freezer until the weather cools enough.

Every year we get posts on the local discussion board with pictures saying they froze the comb for X number of days and then placed in in a Tupperware or other container and under the house or some similar dark place only to find the comb destroyed by spring. Last year in bee school a member of the class asked me about this specifically and said if he placed them in the freezer for days and then immediately placed it in lawn trash bags and sealed them completely and absolutely shouldn’t that work? I told him that “in theory” his plan would work but my experience is some eggs will hatch and if conditions are right they will destroy his comb.

On Para-moth (paradichlorobenzene) crystals: They do work but it is not a one and done application. Use them generously. Periodically check them through the storage period and replenish them as needed. They do “melt” as they release their gas into the supers. I’ve seen some people tape the edges of the supers to make a gas seal. Unfortunately this dark, sealed environment is also ideal for the moths when the para-moth dissolves and no longer provides protection.

Using open air and light: I did this one year with good success. I simply have too many supers now. Also, anything I place outside now is subject to squirrels who seem to like the comb, pollen, honey residuals.

BT (bacillus thuringiensis aizawa): Reports are, this works well. As you know it used to be a recognized method of wax moth control in bee hives but the company decided to not renew it’s license for use as such. Data used to be on the Clemson site. BT for use on crops is recognized as non chemical, organic bio control method and approved for use on organic crops. While an approved organic pest control method, it is no longer legal for use in bee hives.

I have a friend that uses BT and sprays the comb coming out of the extractor.

If you do not protect your comb from wax moths don’t despair, I understand the larvae are great as fishing bait.
