I for one, like the benefits of the screened ipm board.
Now i see sbb and never know if someone is say screened bottom board or solod bottom board.
So i do not use the abbreviaton sbb. Its confusing to me. But when i refer to my screened bottom board, i do not use those words either, because to me it refers a screen with no option to close. So i use the term "ipm" and then everyone knows what im talking about.
Now with the terms out of the way, i do like my ipm board. And when its 105° f outside. They are outside the hive bearding and to me thats a waste of them. Like all the workers on cig. Break. Nothing getting done, or at least not as much that could be. All i have to do is crack it an inch and within a few monutes, they all go back to work.
Another thing, i dont have to open the flood gates for wax moth and shb for ventilation either. Open the air, yet easy guarded entrance still.
I don't see anywhere in this thread that says ALL packages installed over open mesh bottom boards would abscond.If open mesh bottom boards caused these 2 packages to abscond, why didn't the other 24 act the same way?
Nice explanation.....and kinda funny too. Thanks for the am smile!Here is my opinion: The reason that "they go back to work" is that by opening a big hole in the bottom of the hive, you have disturbed the bees' evaporative cooling balance, and now a bunch more of those bearding bees are called to go retrieve/haul in more water into the hive, and (likely) also go to work to block/reverse that extra airflow through the hive!!!
Bees want their brood area at 93-94 degrees F, When the ambient air temperature [outside] the hive is 105 degrees, it doesn't matter how much ambient air [at 105 degrees] is flowing through the hive, the temperature can never be lower than 105 without evaporative cooling. It just doesn't work that way inside a hive, or anywhere else.
The key to a swamp cooler operation is controlled ventilation, enough to move the humid air out so it can be replaced with dryer air, but not so much outside air that the cooling effect is overwhelmed. Bees are masters at controlling airflow in/out of their hive - that what they do. Its somewhat presumptuous on your part to think that you can do a better job of that, particularly since you clearly aren't willing to commit to being the HVAC 'controller' on a full-time basis.
Welcome to Beesource, Sharon!Why is it a problem?
