How I Prepare My Beehives For Winter

    The following was originally posted on December 7th, 2015, but was edited and updated on October 27th, 2016, to reflect my current practices, such as they are.

Something weird happened. I got several emails from people asking me what I do to prepare my hives for winter.

I’m no expert, but here’s what I do, and what I do could change entirely by this time next week.

So the big question is: “How do you prepare your hives for winter?”

What Makes Friendly Springtime Honey Bees Turn Mean?

My healthiest honey bee colony, one that was always full of mean bees but has been playing extremely nice so far this year, is back to being mean. Any slight vibration on the hive and the bees come pouring out. I’m not sure what reactivated the mean gene, but these bees are definitely not playing nice anymore.

Things that may have triggered the mean gene (and I’m just making this up):

Attaching Mesh With Pushpins (Instead of Staples)

I removed the shrew-proofing mesh from my hives yesterday so I could clear out the dead bees that have accumulated so far this winter. I reattached the mesh afterwards with the use of a staple gun that produces a loud bang that vibrates through the hive and riles up the bees. But this comment changed everything:

“Would it be possible to secure it [the mesh] with drawing pins rather than staples?”

It’s absolutely possible. I did it today, just five minutes ago.

The drawing pins / pushpins work just as well as staples as far as I can tell. That mesh isn’t going anywhere.

Now I can easily remove the mesh, clean out the dead bees and reattach the mesh without bothering the bees. I thought I might need to find a different method for keeping the shrews out of my hive for next year. Not anymore. The mesh attached with thumb pushpins instead of staples works perfectly. At least that’s my story for now.

Thanks for the tip, Emily.

NOVEMBER 19, 2016: The original version of this post referred to the pushpins as thumb tacks. The more common name (at least in North America) is pushpin, so I changed all the “thumb tacks” to “pushpins.”

Moisture Quilts vs Hard Insulation

I’m a true believer in moisture quilts as the best overall ventilation and moisture reduction aid for Langstroth hives in the winter. I’m a true believer because I’ve seen soaking wet hives become dry as a bone within a week of having moisture quilts installed.

Empty moisture quilts are excellent ventilation aids in the high heat of summer too, allowing the bees to regulate the temperature of the brood nest with less fanning and to cure honey sooner. Moisture quilts are also really cheap and easy to make. Everybody wins.

Quarter-Inch Mesh Doesn’t Always Knock Off Pollen

    The following post was last updated on October 14th, 2016.

I was surprised to see some of my bees bringing in pollen today.

Judging from the colour of the pollen, my guess is that it came from Japanese Knotweed. It could be Honey Clover too. I still see some of that around (what a fantastic plant that is). I saw bees from another hive bringing in yellow pollen, probably from Goldenrod, though it seems late for Goldenrod.

This is the first year I’ve used quarter-inch / 6mm mesh to keep shrews out of my hives. I was told to put the mesh on after the bees have stopped bringing in pollen because supposedly the mesh opening is so small that it knocks the pollen off the bees’ legs as they go through it. NOT TRUE. Every bee that came in with pollen today had no problem getting through with the pollen still intact. So…

A Mouse Chews Into a Frame of Honey and says, “Oh yeah, that’s it.”

I had some frames of honey stored in a swarm trap in my shed and a mouse found a way in and probably came back night after night and had a feast. Here’s a photo of a frame of honey that’s been partially eaten by the mouse:

Here’s the view from the other side of the frame. You can see how the mouse chewed through the plastic foundation and the wood of the frame.

Winter Mouse-Proof Mesh

My patented mouse-proof entrance reducers worked well enough for us last winter. They’re cheap and easy to build. But I decided to try something different this year. It’s not as cheap and easy, but neither is it complicated. I simply stapled some half-inch mesh over the entrances of the hives like this:

I got this tip from a Brushy Mountain video (I just can’t remember which one). I chose this method for mouse-proofing the hives this winter because it provides better ventilation. I just hope it doesn’t provide too much ventilation by allowing more cold wind to blow through the hives.
