@ Seeb,
Yes, I kept the 1" dia. straight fitting on the end of the vac, to aim at bees not insulation. Bees were mostly on the comb, came out to the exterior corner, or on the ceiling in the back. Remember, the bees have already chewed away the insulation to make space there. I guess they survive. That's probably some of the hive trash I saw. Maybe that's why they only live six weeks.
Insulation isn't good for people either...makes me cough, I try to keep a mask on but you can only imagine: veil, gloves, mask, safety glasses when cutting. I feel like an astronaut. I started early to help with the heat issue but County curfew for noisemaking is 7am-10pm and don't want to deal with an irate neighbor mad at the sound of a saw.
If the colony looks healthy, I typically cut the brood below the honey for frames, and put those honey trimmings in a bucket with lid, to feed back later. I use an an top eke,during a flow, chop the wax so they don't drown in honey, and pull the feed tray after 4 days to clean/check for SHB larvae.
I didn't expect so much honey but should have, due to time of year. To carry the heavy comb (because its MELTing...)...clean, shallow Sterlite tub, WAX PAPER (which I ran out of yesterday) to keep it clean, on a supporting rectangle of Luan or 1/2 foam board. This honey was capped and so clean I'm contemplating human consumption. It's in the freezer now.
