BienenWohl for Varroa Treatment

[jtow]

Haven't use this, saw the article on a "green" beekeeping forum, mostly europeans. Sold in Germany. Curious if anybody has used or spoken with someone who has used this.

I observed the videos and read the data.
It does not cite the active ingredient,s.
It appears to be very similar to an oxalic acid dribbling method. If so, you can make your own liquid for a few pennies/application.

The ingredients are these:
Active Substances: Oxalic acid, citric acid, propolis, alcohol and essential oils. BienenWohl® is a mixture of substances that are harmless to bees. These substances become undetectable after just a few days, and they leave no residue in the wax or the honey. An efficacy of up to 96% can be achieved during the broodless period. The amounts of citric and oxalic acid contained in a dose are about the same as in 50 g of spinach.

Oxalic acid is a very interesting organic acid. However it acts like an inorganic acid.
BTW,
Oxalic acid is also found in chocolate.

Interesting products this Austrian site offers. They also sell chew strips for hives. They claim that the bees try to remove it and start going into a cleaning frenzy and therefore remove varroa too.
