Re: Mite load level to trigger treatments?
I am doing ether rolls though there are certainly other methods such as alcohol washes or sugar shakes will work as well. I spend at least a good minute shaking and rolling them before I feel that I have dislodged most of them. You can count the mites on the side of the jar or I prefer to dump the bees add a little water and count the "floaties". About the only time I will use a sticky board is to monitor mite drop after a treatment. I am aware that brood greatly skews your counts which is a big reason why those elevated late summer counts are so much worse than the numbers indicate. With less and less brood your mite numbers can quickly overwhelm hives. In other words if you are seeing double digit numbers late in the summer and still have considerable brood in the hive you better look out.
