Is anybody still using Oxalic Acid

D Coates, how often do you treat? Do you buy your OA locally or order it from the same site where you bought the vaporizer?

[wildbranch2007]

my question on using Oxalic Acid has always been, since they say you get 99% control when no brood is present and so most beeks use it late in the fall early winter. Haven't the mites allready compromised your winter bees?
no brood means no more bees for winter, I was taught/learned to treat the mites early enough that they were gone when the queen was raising the winter bees??

I dont wait until late season broodless for this reason. I do 2 or 3 treatments a week apart right after harvest and again in spring

Hi danno, I sent a PM to perhaps connect locally on this subject, I would really like to add OA to my arsenal

I treat 3 times at during the late Fall. When it's above freezing, there's next to no brood and the mites are exposed. I bought my Oxalic Acid at the local True Value store. You use very little I don't think I'm even through 1/4 of the container and I bought a little one. Look in the paint section for a container of Wood Bleach.

go www.scientificbeekeeping.com randy has some result he done on this

Wildbranch, I too do not wait until fall to treat my bees. Randy Oliver insists that you must have any treatment done by the 15th of Aug in order to have healthy winter bees. I have used this date also as my target to be done and have been successful so far. I do three treatment vaporized one week apart when I have used OA.

i hope to not misdirect the thread. In a german video, they are direct applying a varroacide to package bees. I dont believe it is acid.

Does anyone have an idea what it might be? Described as a systemic treatment and , I guess, germany approved at that time

What you see on the German video is not an acid; they use Perizin (liquid Chumaphos). I would never ever use this nasty pesticide; it contaminates wax and eventually ends up in honey.
