Wax Moth Crystals

Our Wax Moth Crystals (16 oz) are made from paradichlorobenzene and are specifically formulated for beekeepers to protect stored comb from wax moth damage. Unlike standard mothballs, which use a different active ingredient, these crystals are designed to repel and eliminate wax moths without leaving a residue on the honeycomb.

Drawn comb is one of the most valuable assets in beekeeping, and protecting it from wax moth destruction is essential. These fine crystals release a vapor that prevents adult moths from laying eggs and helps eliminate larvae already present in the comb. They are ideal for use when storing supers or comb through the fall and winter months, ensuring your frames remain clean, intact, and ready for use the following season.

Key Features and Benefits

• Active Ingredient: Paradichlorobenzene (PDB)
• Container Size: 16 oz (protects 50 cubic feet of storage space)
• Application: Prevents adult wax moths from entering stored comb and eliminates larvae.
• No residue: Safe for comb storage; air out before returning to the hive.
• Use: Store with drawn comb in sealed containers during off-season.

Detailed Description

These Wax Moth Crystals work by slowly releasing a protective gas when placed inside a sealed storage container with drawn comb. The gas creates an environment that wax moths cannot tolerate and prevents them from laying eggs. It also kills existing larvae that could otherwise damage or destroy comb.

Beekeepers typically use these crystals when storing supers or drawn comb during cooler months when hives are inactive. To use, simply sprinkle the proper amount of crystals in the sealed container according to the space volume:

• 1 oz protects 3 medium 10-frame boxes

• 1 10-frame medium box = 1 cubic foot

• 1 10-frame deep box = 1.5 cubic feet

• 1 8-frame medium box = 0.86 cubic foot

• 1 8-frame deep box = 1.25 cubic feet

• One 16 oz container protects up to 50 cubic feet

Always allow equipment to air out thoroughly before returning comb to a live colony. These crystals are not to be used inside active beehives.
