It is the first week of Oct. By now mite treatments should be getting finished up.
If you haven't fed 2 gallons of fumigilin do so now. The later it gets, the less likely the bees will take down syrup.
Make sure entrance reducers are in. The cooler weather will make the mice look for a warm place.
Other than that it is a waiting game.
I usually put winter covers on around Thanksgiving. To early and the hive is to warm. They might then keep raising brood and eat their winter stores.
Keep an eye on the weather, if we are going to get a big snowstorm, put them on.
Last year it didn't get cold until mid Jan. That is when I covered mine, and they all made it.
Temps in the 30's are a cakewalk for bees. It is the teens and lower that make covering a must.
