Jeremy (owner of the Vent Bees) captured the history of what the trap-out on this looks like this video:
And here you see the early buzzin’ and pawing at the new box, which was packed with a bunch of old comb from an earlier cut-out:
And here’s some photos of the pre-relocation work:
So, Jeremy’s Dryer Vent trap-out worked about 50% – they managed to be orderly enough to persist in slowly entering the trap-out cone one-by-one over the past 3 weeks. After taking the box down for inspection, some of the trapped-out bees had set up home inside and started caring for the uncapped brood and building burr comb to attach it to the frames and box walls. But with neighbors starting to complain about the buzzing, we decided to move ’em out.
The vent has a 5″ x 6″ opening, leading to a 1.5′ x 1.5′ x 8′ non-functional space left open to the outside world. (and filled with not only bees, but also paper wasps, wood borer beetles and a couple of roaches). This was the result of a interior remodel, which should have included sealing-off or at least screening-off the opening.
Putting in a borescope (from ThinkGeek) only showed a lens absolutely full of bees (rather curious bees poking at the LED lights and wondering what creature this was). Brought out the bee vacuum and captured most of the visible first layer off of the trap-out cone face, and those visible from the vent.
There was about 1/2″ thick stucco surrounding which would cause too much siding damage, so we opened up the dryer vent using tin snips like a can, folding aside the flaps. Puffed in a little smoke, but the sound change sounded wrong, and I noticed the bees had vacated the entire first layer of comb when the smoke came in. So we put the smoker aside and instead decided to opt for the gentler sugar spray and leave them on the combs method.
Inside revealed 7 – 6″ x 7″ combs neatly built parallel to the wall-face. All new comb, and about 1.5 combs of honey.
Yuka had to vertically slice some of the combs to fit through the opening, but one-by-one was able to gently remove each comb, with most of the bees still on the combs.
After all the combs were out, another session of vacuuming to remove the straggling bees and finish by foaming the vent with a backer board using self-expanding foam to keep out the future intruders.
Final tally, 6 medium frames of comb. And a foamed up vent. And Jeremy now has his first experiences with trap-outs, light demolition, vacuuming, framing, packing up a moving hive
