Early August I had a drop rate of around 10 per day on a sticky board. This was a BOOMING hive so I wasn't too concerned. I decided to treat after harvesting with MAII. I couldn't help myself and pulled the sticky board to take a peek after 1 week. HOLY COW!!! I had around 1200 dead mites on the board . . . YIKES! Not sure if this hive would have made it through the winter with this kind of load.

what did you treat with? I used apiguard and oxalic and monitored only 4 out of 30. After a week 3 dropped 1000s each. The boards were red/brown. The 4th had only about 50. They must be doing something right
I treated with a Mite-Away II formic acid pad.
10 mites a day is a heavy miteload. 10 seen multiply by 100, those hidden are in the brood. So glad that you treated, you would surely have lost that hive, no ifs, ands or buts....Have a wonderful and most awesome day, health. Cindi
