The nectar flow for most of us is over. Some beekeepers are getting some late summer honey. It is very spotty. A few beekeepers are getting some Goldenrod nectar but they are the exception not the rule.
Mite treatments are being put on hives right now. Bees emerging now, until brood rearing stops, are our winter bees. Winter bees live through the entire winter and are not replaced be any new bees. We want the winter bees as mite free as possible for increasing the odds of over-wintering success.
The current cooler weather is appealing to beekeepers putting on Mite Away Quick Strips (MAQS). The vapors of MAQS are a little less intense when it is in the 70's and the product still works well. When the temps are in the low 80's for the first couple days, there can be some bee and brood mortality. It usually is not much of a problem. But if it gets too warm there is a possibility that a queen can get zapped.
Other mite treatments are not as intense, but their treatment time take longer. ApiGuard is a one month treatment and ApiVar is a six week treatment.
But the common theme here to get in your head (to the tune of it's all about the bass) It's all about the mites, bout the mites, bout the mites.
Colonies not heavy with winter stores should be fed now. Don't wait to feed.
Fall feeding is heavy syrup. 2:1 sugar water, 2 parts sugar to 1 part water. The other feed to use is ProSweet. ProSweet is just like honey. The bees take it down and put it in the cells and they are done. Sugar water the bees have to dehumidify it to convert it to honey.
There is some work to do now with our colonies, September is a week away.
