Simple question.
During the course of the year, would you expect to see Varroa on a board if they were present in a hive? That is without any treatment in there!

8x Langstroth, a few Lang nucs,1x TBH, and about 17 mating mini nucs
Simple answer: yes.

I started this year: 2 TBHs. One had lots of varroa: daily drop 3-5.
One had little weekly drop 1-2.

So perhaps not every day.. But every week...

16 a mix of Commercial, National, 14 x 12, Dadant and a Warre
Yes but with a couple of qualifications

Either a sticky board or a drop distance in excess of 50mm to stop the critter climbing back into the hive.

No evidence of ants - they eat the fallen mites and produce a false zero count

It is very easy to be lulled into a "zero count therefore no need to treat" frame of mind only to lose a colony because the count was "skewed" by the above.

Probably about 5/6 at the moment
This is my first colony and I have just started the second Apiguard treatment.

I have a first drop count of around 70 a day, but last week when i changed the Apiguard over, I had something between 500 and 700 for the week.

Is the use of Apiguard cumulative to that extent, so that it can increase by a factor of 10 over a week, or could it be ants were eating the mites from the board? I have seen them on the outside, but not on the board when I have done my checks.
