Recommended dose is 2 strips per brood chamber. So for most of my hives,
I'd need 4 (or perhaps 3 for weaker) per hive. Cost here is $2.70 per
strip. Labor takes us longer for Apivar--we've applied both in the past
few weeks, esp if 4 strips are needed.
Reality wise, 2 strips of Apivar may do it, but I don't know.

than here.
Yes, our colonies are in full brood production in late Jan, and chock full
on drone brood by mid February.
