24 Hour Mite Drop Count

I did a 24 hour mite drop count on the three langstroth hives. The counts were as followed:

• Worker Bees... - 2
• Lib-BEE-taria - 2
• Bee Glad... - 1

Looking back at my records, these are unusually low counts which I can't yet explain. I will look back at my records and look for any possible patterns to explain this.
