30 varroa in three days WITH the apistan. What was the drop BEFORE the apistan? That's an important number as many of the Varroa are resistant to it.

Assuming the mites are NOT resistant, I think you could have skipped the treatment. But looking at those numbers I'm guessing the mites ARE resistant.

Haven't done it, I have done it in fall with 0 count....I was told to use apistan for a count, remove after the count, if need to be treated, I would use Oxalic acid. Would you do a treatment?

With a drop of 30 mites in three days WITH apistan? No I would not treat.

I don't use aptistan at all, but I certainly would want to know what the drop is without before I found out what it was with. The Varroa in my part of the country are immune to it.
