These sticky board counts look pretty good. They come to 26 per day and 10 per day. If the counts come to 50 per day or higher be aware that they are getting in the danger zone.
The fall of mites is higher during very hot weather (above 90, as we have had recently). If your sticky boards were in the hives during this hot spell, the numbers will give you over-estimates. In other words, the mite populations are not as high as they appear to be.
Are you using screened bottom boards? If not, I recommend that you get some and swap them for the solid bottom boards. This is a good way to get rid of live mites that fall from the bees. And they are especially useful during hot spells when the mites tend to lose their grip on the bees.
Also, you do not need to feed syrup now. The bees have had plenty of time to find flowers and there is a good honey flow on in most parts of the state.
