Vaping from above / through the crownboard

[Curly green finger's]

Just wondering if any of you are vaping this way and your results.
Thanks

 

[Erichalfbee]

Yes but via an eke. It’s easier but I doubt the results are any different.

As the temps drops you will get more onto the bees from above as it crystallises quicker and drops faster

Thanks for that , im using a thin eke with a bit of copper pipe (10mm )through the side of the eke .

Doesn’t matter.
The bees spread it around
It’s like vaping in the day when lots of foragers are out or vaping having taken a super off then putting it back

 

[blackcloud]

They can't spread it around if it's dropped down through the floor mesh

Unless the board is jammed against the OMF, anything that drops through is effectively gone.

No of course not but enough coats the frames and the walls of the box

I don't do any wood turning unfortunately but liked what Pargile did to vap nucs from above. I have made a small box out of ply which sits above the feeder hole and vap that way or from underneath. Yet to workout if there is a difference.

I vape from above too via an eke, mainly as my colonies are in polyhives with plastic entrances or in WBCs and a Sublimox pipe doesn’t work vaping below. For the first time I’m overwintering some colonies with a taller stack (7 over 7 and a reduced super box, dummied down with fat dummies, so there’s space in the spring for early expansion and simulating a tree type shape in nature). So have been wondering if the acid will get around effectively.

As I said. You can vape taking a super off then returning it and everybody still gets a dose

I don't see why not. I cobbled a plywood roof together to fit my two tier poly nucs and judging by the clouds coming out of the entrance, I'd say it gets everywhere.

I vape from below and crack the cover board slightly open to create a chimney effect and wait until vapour comes out of the top. Then you know it's well dispersed.

I vape through the entrance and don't bother closing the floor (bar my Abelos), just use a bit more. Fast and effective.

As a test, (in full PPE) fire off a couple of grams into the air and look at the cloud generated and size/shape. Some will disperse through the floor but most of the cloud is forced around the hive/frames coating everything in crystals.

I do it this way as many units to treat over a 3/4 stage process x time.

Roughly how large is your "vaping" box ? Trying to vap from below on WBC hives is near impossible.

Took some videos a few years ago vaping from above via an eke and a clear crownboard.
IMO it seems to disperse better than doing it through the entrance with an OMF you can see the OA get pulled down through the frames as the bees start to fan as opposed to fighting the direction of the hive ventillation doing it through the entrance.

I've a "winter" honey super directly under the crown board. The CB has a beespace above the super's frames.
I could just vape through the CB feed hole with a "box" to enclose the vapouriser over the feed hole (as suggested above), but would it be better to remove the CB and inset an eke for vapouriser and but the CB back on with the feed hole still covered?

It will work both ways.
Problem is if the bees are clustered passive OA treatments don't penetrate the cluster easily.

Just done mine. I use an eke with perspex lid fitted. Notch in side of eke. Allows me to see what is going on. I vape on a mild day when bees not likely to be in cluster .

around 10cm x 10cm (any smaller would have been a bit too fiddly).
