Wax moths in stored equipment
Wax moths are destructive pests of stored beeswax combs, causing significant damage if left uncontrolled. Wax moth larvae tunnel through combs, feeding on beeswax, pollen, and honey residue, leaving behind webbing and debris. Severely infested combs can be completely destroyed, rendering them unusable for beekeeping. Wax moth infestations are particularly problematic in stored equipment during warmer months. Prevention and control measures are essential to protect stored combs and maintain their value. Stored drawn combs, especially those with pollen or brood residue, are highly susceptible to wax moth damage.
- PDB crystals (paradichlorobenzene)4
Using PDB crystals (paradichlorobenzene) is a chemical fumigation method to prevent wax moth damage in stored beeswax combs. PDB crystals release vapors that are toxic to wax moth eggs and larvae, effectively preventing infestations. Stored combs are stacked in airtight containers or bags, and PDB…

- BT (Bacillus thuringiensis)3
Applying BT (Bacillus thuringiensis) to stored combs is a biological control method to prevent wax moth larvae from damaging beeswax. BT is a naturally occurring bacterium that produces a toxin specific to moth and butterfly larvae, including wax moths. BT products, available as sprays or powders,…

- Freezing equipment3
Freezing stored frames is an effective non-chemical method to kill wax moth eggs and larvae. Similar to small hive beetle control, storing frames in a deep freezer at temperatures below freezing for 24 to 48 hours eradicates wax moth pests. This method is suitable for smaller quantities of…
