Thanks for reaching out with your question!

We normally use deadouts as an opportunity to toss certain frames. Here are the frames we consider culling:

1. Brood frames that are older than 4-6 years: it's good practice to rotate out brood combs at least every 4-6 years. You can also toss any frames that you received with a nuc (if you purchased a nuc) that are of unknown age.
2. Frames that are full of pollen: Pollen loses nutritional benefits with time, and bees can’t clean it out.
3. Frames with dead, capped brood: We don’t have data to know whether or not dead brood can contribute to pathogens in the next colony, so we often suggest beekeepers consider tossing frames with dead brood as a precaution. (Adult bees use their mouthparts to break apart and remove dead brood.)
4. Frames that are thick with mold: Some mold is fine for bees to clean out, and mold isn't known to harm honey bees. Frames that are really thick with mold will take the bees a lot of work to clean, so we recommend tossing these frames.
5. Note: if you suspect American Foulbrood, you will need to follow recommended guidelines to prevent spreading the disease.  

Bees will reuse and clean combs. They can't easily move or clean out stored honey or pollen.

I normally store honey frames in the hive outside but with entrances blocked off so that critters and bees can't enter. Some people with extra freezer space store honey frames in their freezers.
