1) You mentioned that you have an inner cover without the vent notch. Did I get that right? What does this do for moisture and air flow? 3:21

2) Do varroa prefer nurse bees over the working foragers? Do the nurse bees go up and feed in the rapid round feeder? 18:47

3) I bought a bag of seeds from Eden Brothers pre-spring but never go them planted. Will they be fine for next Spring? 26:34

4) I bought a Varroa EasyCheck and in the directions it talks about CO2 mite checks. Have you done this? Did it work? Does it kill the bees? 30:31

5) My husband was a Master Beekeeper for over 35 years. One morning he was stung on the lip and he went into anaphylactic shock. 45:36

6) I found a larva on the landing board of my hive. Later on I noticed two dead varroa mites next to it. Maybe the queen is VSH? 51:13

7) We are in the process of building a Long Langstroth hive based on your plans. Thinking ahead to making legs and wondering if the hive should be level or have a slight tilt as the common Langstroth Hives have? 54:48

8) I have an observation hive, and have a question about pollen storage. I noticed they store dry pollen and wet pollen. Does the dry pollen have a much longer or indefinite shelf life? 1:03:40

9) Sometimes swarms hang onto locations outside and make comb and if no one messes with them, they stay there. Why is that? 1:07:51

10) Why do bees occupy an intermediary location to bivouac? I wonder why the scouts don't identify an share the location of the new location prior to departure? Why don't scouts figure it out and fly directly there? 1:11:14
