The shims have a 1/4" hole at the back and under the excluder so when I want to treat I will slip into the shim a board that will cover the excluder and thereby prevent the OAV from moving out of the brood boxes into the supers. The boards can be removed when the vapor has settled but while this is going on the workers still have access to the supers.
    Hi John. The shims sound interesting and something worth trying out. Could you possible post a picture?

    The reason that's on the label is because it's considered a miteacide.
    If purified water would kill mites and you was going to use that as a miteacide they would recommend you take the supers off simply because it's considered a miteacide.
    I recommend you follow directions but that's my two cents.

    I am sure not all OA is created equal. That is why I order the lab grade stuff with purity specifications. No wood bleach for me.

    Just an FYI, Savogran wood bleach is 99.7% pure.

    And from what I have read the other 0.3 or impurities in OA are just iron salts.

    Yeah..., that was a joke that obviously fell flat. Oh well. I use the cheap stuff, the Savogran sold in most hardware stores. Other than being a bit pissed about the hot iron I shove in their home the bees do just fine.

    Here is the setup that I made with the excluder in a shim with a top cover so that I can close off the brood chamber and do an OAV treatment without having to remove any honey supers

One way that could be done is to insert a piece of thin wood or plastic between the top brood box and the bottom honey super. You may be able to do that without actually having to remove the super(s). A piece of scrap 1/4" plywood should be the easiest to handle, or a piece of plexiglass comes to mind if you are prepared to buy something.


    Removing the honey supers (or blocking them off completely) has a practical benefit. The brood boxes (say two per hive) are a more consistent cubic volume than a brood area + a random number of supers. Having a more consistent volume makes it easier to apply a consistent dose of OAV per cubic inch of brood space.

    .
    A simple solution to this may be to use a cloake board under all supers rather than a plain excluder. Then when using OAV you could simply slide the solid board into the cloake board insert and isolate the brood chamber from the supers

    John, do you use a filler board to block the gap when the cover is not in place? Seems like a really large upper entrance for the bees to defend, and right next to the honey too.
    Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.

    JW I will restrict the entrance a little when I first super up but once the flow starts that will be wide open and be the main entrance. Once the nectar flow begins there will be no robbing going on, I can actuall leave open honey around and the bees pay no attention to it. Just dont leave any honey around when the flow is over.

    Why in the world do you want to contaminate your hive with OA?
    It is obvious you do not understand the life cycle of the Varro mite.
    If you get your bees back to their natural state 4.9 mm or smaller!
    You will eliminate the Varro mite problem!
    Do the reaserch, the Varro mite was never a problem until man thought, bigger is better.
    I have natural bees sized hives, have zero problem with mites

    It was not a joke. Lab grad OA is inexpensive. One bag will last me a lifetime.

    Can not find anything on the "wood bleach" label stating to remove or block supers. In fact nothing about treating bee with it all.

    No data on not supporting that assertion either!
