Storing empty frames after harvest

Empty honey frames, especially those with a drawn comb (even if empty of honey), are highly susceptible to pests like wax moths. Proper storage is crucial to protect this valuable resource.

Here's how to store empty frames after a honey harvest to prevent wax moths and other pests:

1. Extract All Honey Thoroughly:

Ensure frames are as dry as possible. Any residual honey will attract pests and can lead to fermentation and mould. Allow bees to clean up any remaining honey in the frames if possible, or spin them dry in your extractor.

2. Choose a Storage Method for frames:

Cold Storage (Freezing):

Method: This is the most effective non-chemical method. Place frames in large plastic bags or storage tubs (e.g., totes and garbage bins with lids). Freeze them for at least 24-48 hours at −7∘°C (20°F) or colder. This kills all stages of wax moths (eggs, larvae, pupae) and other pests.

After freezing, once frozen, you can remove them from the freezer. For long-term storage, transfer them to airtight containers (like plastic storage totes with tight-fitting lids) or well-sealed plastic bags. This prevents re-infestation.

Pros: Safe, effective, chemical-free.

Cons: Requires freezer space, which can be limited to many frames.

3. General Tips:

Inspect Regularly: Periodically inspect stored frames for signs of wax moth activity (webs, frass, tunnels).

Cleanliness: Keep your beekeeping shed or storage area clean and tidy.

Mouse Guards: Ensure storage stacks are protected from mice, which can chew through

comb and wooden frames. A screen bottom board and a solid top board are good.

Dryness: Always store frames in a dry environment to prevent mould.

Freezing followed by airtight storage is often considered the safest and most effective for hobby beekeepers.

Final Thoughts

If you're a hobbyist, honey harvesting is not just about collecting a product—it’s about celebrating the work of the bees and sharing their gift responsibly. With simple tools and respectful methods, you can enjoy rich, delicious honey while ensuring the health and sustainability of their colonies.
