Tips on Using 6mm / Quarter-Inch Mesh

It was 18°C / 64°F today and the bees in all of my hives — even with shrew-proofing 6mm / quarter-inch mesh covering all the entrances — were out in full force.

I’ve heard arguments that the bees can’t get through quarter-inch mesh. But that’s not true. If it was, my bees would have been locked inside their hives behind the mesh all last winter. The bees in the above photograph wouldn’t be flying around today.

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, and could be updated without noticed at any time in the future.

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.

Wondering When to Remove Shrew-Proofing Mesh

July 2019 Introduction: I remove the mesh from the top entrances of my hives as soon as I see bees crowding to push their way through the mesh. As long as the hives aren’t buried deep in snow so that shrews can walk right up to the top entrance and hop in, I don’t worry so much about mesh on the top entrance, though I do temporarily remove them in the winter on warm days when the bees are trying to get out on cleansing flights.

I used 6mm mesh (quarter-inch mesh) on my hives this winter for the first time because I lost most of my colonies last winter when shrews managed to squeeze through the half-inch mesh I kept on the bottom entrances. I’m not sure if the shrews got into the hives through the top entrances, but to be safe this winter, I covered both the top and bottom entrances with 6mm mesh. Now I’m wondering when I should remove the mesh, at least from the top entrances.

Birds Eating Honey Bees

I found bee body parts scattered all over the snow near my hives today.

“Ah man, what the hell is this?” was my first reaction. It was a natural reaction considering the last time I saw bee body parts was inside one of my hives last February — when shrews preyed on most of my bees until they were dead.

First Sign of Shrews in a Hive

I had eight honey bee colonies going into winter last year (2014) and all but two of them were destroyed by shrews. The shrews squeezed through the half-inch mesh I’d been using since 2010 to keep mice out. But no one ever told me about shrews. The little buggers easily squeeze through half-inch mesh. They slip inside and pluck one bee at a time from the edge of the cluster. They eat the bee’s innards, toss away the bits of legs and other desiccated body parts, then climb towards the cluster for more… until they eat approximately 125% of their body weight in bees every day, gradually reducing the size of the cluster until the colony is dead.

That’s how I lost six colonies last year. With only one mated queen and no extra brood, I performed a miracle and managed to expand my remaining two colonies into five colonies last summer. They may not be the strongest colonies I’ve ever seen, but they’re hanging in there (so far). All of my hives have quarter-inch mesh covering every entrance now. Shrews will never get anywhere near my bees again.

Looking back on my notes from last year, along with photos and videos I shot and the memory of the experience burnt in my brain, the first sign of a shrew inside one of my hives seems obvious. It’s in this photo from January 5th, 2015:
