Wax moths lay their eggs in beehives and stored frames, where they lay their eggs. The resulting wax moth caterpillars can wreak havoc, tunneling through the wax foundation in search of pollen and brood. A strong hive will simply throw the eggs out, but weak colonies and especially stored frames are at risk.


To avoid wax moths in stored frames, store them either in very cold temperatures or with granules of paradichlorobenzene (PBD). Paradichlorobenzene is a chlorinated aromatic hydrocarbon. It is a fumigant insecticide and repellent. Paradichlorobenzene turns directly from a solid into a gas, a process called sublimation. The target organisms are molds, mildews, and insects, but paradichlorobenzene can also be toxic to people and other animals.

Wax Moths are such voracious eaters they will even chew up the inside of a hive.
