  • According to the New South Wales Department of Primary Industries, "wax moths are major pests of stored or unattended combs," and may cause damage to beekeeping materials by eating wax in abandoned or underpopulated hives. The simplest way to remove wax moths from a hive is to freeze them----all forms of wax moth life will cease after approximately 4.5 hours of exposure to temperatures under -6.67 degrees C.

  1. 1

    Remove hive frames from the hive. In infested hives, wax moth damage will likely be visible on combs.

  3. 3

    Remove frames from freezer. Using a knife, cut away damaged comb from healthy comb. Using a knife and your fingers, remove remaining wax moth bodies from hive and frames.

    Reassemble the beehive.

Tips and warnings

  • Beekeeping experts agree that it is easier to prevent wax moth infestation than to kill wax moths once they have take over a hive. Wax moths rarely gain footing in hives with full adult bee populations. To prevent infestation, it may therefore be advisable to remove frames from underpopulated sections of a hive.
  • According to The Bee Works, beekeepers looking to exterminate wax moths without upsetting an existing bee population may set up a narrow-mouthed container filled with a mixture of water, sugar, vinegar, and ripe fruit near the hive. The smell of the rotting fruit will attract the moths, who will then become trapped in the container and drown in the sugar liquid.
