Damaged combs showing silken galleries
Wax moth larvae damage or destroy the combs by chewing through the beeswax cells as they feed on cocoons, cast skins, and pollen. They spin silken galleries for protection from bees that will remove the wax moth larvae if they get the chance. Beeswax combs are often reduced to a mass of webs and debris. Wax moth larvae seldom attack new beeswax combs or foundation and they will not feed on blocks of pure beeswax or candles or such items made from beeswax.
