The other day I dusted my hives with powdered sugar (2 cups per hive with a flour sifter)...then I put sticky boards down to see how many would drop.
In the first hive (All American) there were roughly 78 to 80 mites over a 3 day period that dropped onto the board....so that roughly comes out to 26/27 mites in a 24 hour period.
The 2nd hive had right at 60 mites which put them at 10 mites in 24 hour period (this is a Russian hive).
What is the general rule of thumb on when to treat or what number indicates how bad the mites are?
I have never treated these hives except with grease patties last fall.
