Hello all
after reading the lines below just wanted to write that formic acid gel
has been in
use in Finland for more than 10 years.
It is one standard way to treat varroa
I don't know exactly what chemical they use for making the gel, but know
that basic recipie come
from North America.
Packed in thick plastic bags.
Used by placing on frames and 3 -4 slits are made with a knife on upper
side.

> patent on it with Kochansky, Feldlaufer, and Pettis.
>
> The patent was licensed to Betterbee, Inc., of Greenwich, N.Y. in
> 1998 but the product was a disaster.
