End of Season Chores

The bee season is winding down. Most beekeepers have extracted their honey, treated for mites and made sure their hives were heavy with honey. But what remains?
 If your hives are still light on feed, there is still time to feed some syrup. Next week the highs are in the 60's and even a couple 70's are forecast. 
The bees will take down syrup still.
After next week, the weather looks like it will be cooling off. Feeding syrup gets much more difficult when the highs are in the low 50's and 40's.
 So if you have some feeding to do, get it done asap. Consider feeding ProSweet. The bees don't have to convert it to honey, so the feeding goes faster.
 Oxalic Acid treatments can be applied anytime when the temperature is 40 degrees. It can warm up later in the day, just at the time of treatment it should be 40 degrees. At this temperature the bees are in a tight cluster and the treatment works the best. If the dribble method of oxalic acid is done when it is warmer than 40 degrees, the treatment may be much less effective because the bees may be spread out more in the colony.
 Using a vaporizer is more forgiving. The vaporizer coats the bees and equipment with  Oxalic Acid. The vaporizer does a little better treatment than the dribble method, but the dribble method works well when applied properly. 
 Entrance reducers or mouseguards should be in place now. Vermin will be trying to get into the hives now as the temperature cools. Three deep hives are more susceptible to mice compared to a two deep hive when the temperatures initially starts cooling off. In a three deep hive, the bees will cluster in the middle box leaving the lower box mostly empty of bees. With no bees to challenge the mice, the mice set up shop for the winter. In a two deep hive, there are bees in the bottom box to challenge the mice. But as it gets colder, the mice can still sneak into the bottom box and start to take advantage of rent free housing.
 Winter Covers and moisture boards:
 It is too early to cover hives for winter right now. Winter covers can go on anytime starting in November, I usually cover my hives around Thanksgiving. I watch the weather up until late November. If we are going to get several inches of snow, I will run out and put the covers on early. Once there is several inches of snow on the ground the daily temperatures cool dramatically. Temperatures in the 30's are not stressful for a colony. But when high temperatures are sneaking into the low 20's a winter cover should be on the hive.
 Top boxes need to have a 1" hole drilled in the box for a winter exit. This gives the bees the ability to go on cleansing flights over the course of the winter. The reason for hole is this: As winter progresses and the bees move up into the top box, they would have to travel down to go out the lower entrance, the bees will fly out and poop, fly back into the lower entrance and travel back to the cluster.  The bees will get chilled and die attempting to do this.
 The top hole is right where the bees are in the cluster. They can leave the cluster fly out, poop, fly back into the hole and the warm cluster of bees. There are always dead bees all around the front of the hive in the snow. This is normal. Remember, the hive start winter with around 40,000 bees. The population may fall by 50% over the course of the winter. If on March 1st the bees are totally covering at least four frames in the top box, that is a good number of bees to build up to a May divide.
 Winter is coming, the time is short, get the work done. The bees that get saved may be your own.

This is where I drill my holes in the hive bodies. One inch below the hand hold, center of the box.

I use a one inch auger bit. This type of drill with a screw thread on the end that pulls the drill through the wood. When drilling larger holes like this, the drill motor should be on the slow speed.
