In your opinion, what are some advantages and disadvantages of double screen bottom boards?
For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.

In my experience only.  Advantages: Probably for warmer climates very few SHB if an oil, or water pan is used. Diatomaceous Earth has been successful for some but it cakes to quickly for my area. I build my DSBB with 2 3/4  inches between screens, which allows a casserole pan with about 3/4 inch of oil in i to be inserted from the rear of the hive. Before moving a hive I strain the used cooking oil and reuse it.  Messy, yes, but fore thought can make this a non issue .  I see absolutely  no bearding on hives all deeps up to 4 high in the Texas sun.  I use a door on the rear that is bee proof which allows me to change oil without the bees ever knowing I am there.  If you like a landing board the DSBB makes this easy to incorporate in the construction.  I also use the idea of Jim's that is a screened top board with a cloth and sawdust or shavings year round.  I have no mold in the winter.  There are Master Bee Keepers, I am NOT a MB, that leave the DSBB open all year, I have done this also with no bad results I just like to make sure all my girls are snug and comfy.   My major disadvantages Time and cost to build, weight and some added bulk, especially if hives are moved.  I wish I had numbers to prove that DSBB improves mite control, all I can honestly say is that it has to help.  I strap all my hives which helps make them tighter, also cows and horses love to rub on hives and knock them over.  I have LOTS of hogs but they have never been any kind of a problem for my bees.  I first used SSBB and the bees started comb on the bottom of the screen.  Summary; Dsbb will work for you if you want it to work but they won't if you don't want to use them or have a preconceived negative opinion.  Its just another tool.

The biggest advantage is you can decimate the SHB population when you add oil trays. Especially if you have a lot of hives with them.

Good morning Phil.  Taking a break from Bible study this AM Sunday.


Single screened bottom board with tray:
I use several types of screened bottom board,  Freeman has the tightest joints which is important when treating Oxalic acid vapor for mites.  You do not won?t to lose vapors via the screen bottom with a lose fitting tray.

My biggest complaint is cleaning the bottom tray after EVERY rain.  If the water is not removed, a moldy mess precipitates.  I face my hives South, but some rain usually finds it way to collect in the bottom trays.  I use diatomaceous earth  in the bottom tray with pollen patty bait in the center of the tray surrounding by diatonic dust,,,deadly on beetles.

My bees still washboard during hot days with the screened bottom board with bottom tray.

Oddly, this year, my area has few beetles?

Back to Bible studies.

All good things to you beekeepers.

I have been around bees a long time, since birth.  I am a hobbyist so my answers often reflect this fact.  I concentrate on genetics, raise my own queens by wet graft, nicot, with natural or II breeding.  I do not sell queens, I will give queens  for free but no shipping.
