    Default Are screen-bottom TBH's leading to absconding packages?

    I've heard of a number of people losing package bees after trying to house them in screen-bottomed tbh's (with no solid enclosure below). I know that the theory of the screened bottom is supposed to help keep moisture down and help bees winter in certain climates, but is it leading to a lot of bees absconding due to the desire for a more secure enclosure?

    I don't use screened bottom boards in any of my TBHs and I've had no issues with absconding after starting around 12 packages. I have had a number of friends with screened bottom boards that have had their colonies abscond. I can definitely see a correlation.

    Cheers,

    I dont have a TBH but I cant imagine TBH bees desire a more secure enclosure than those kept in langs under the same conditions and with screened bottom boards. Lots of bees are kept around this country on screened bottom boards in varrying climates, IMHO if there are absconding issues Im not sure it could be pointed at SBB as being the problem.

    If your screen is #8 it is big enough to let SHB and ants come right in. Packages are weak at first, and they might not like having to deal with that.

    Keep in mind - I'm referring to screened bottom boards WITHOUT a solid bottom beneath it. Open to the air - and to the light.

    I think most people using SBB' dont run "solid" bottoms beneath them even through winter. I did not see Caklewacks post prior to me responding, interesting then I'm interested in seeing more answers.

    CAKLEWACK- why do you think they are less successful in TBH w/SBB vs. Langs with SBB??

    I can understand why they might abscond in a tbh with a screened bb, that's a lot of space open for a new colony to deal with, once comb is built it would be easier for the bees to control their nest conditions, even a solid perforated bb under the screen would give you a lot of ventilation and might prevent some absconding.

    I wonder about that. The presence of a full Lang box of frames (and maybe foundation as well) would add a lot more enclosure and reduction of open air flow and light.

    It could be just enough of a difference from the open, empty interior of a new tbh to keep the bees from leaving...
