You may vape as much as you want. Your varroa situation is very bad compared to other European countries. What ever you do, it is always positive thing.
My advice: Kill first, count then.
Lasi says: Count first and avoid unnecessary killing.

Lasi used in its research such trickling recipes that no onr has used before.
Coloss had made several years ago "varroa researching standards", but seemengli Lasi has never heard about those.
But I wonder how you can twist every week some oxalic acid joke?.
And vaping every day....
