Type 15 or 30 asphalt felt (roofing felt) is wrapped around the hives in November to absorb heat from sunlight and provide a windbreak for the bees during the winter, just enough extra warmth to allow the bees to break cluster once in a while so they can access all the honey in the hive. More costly commercially available hive wraps may keep the bees so warm that they’re more active and subsequently eat through their honey stores before winter, increasing the likelihood of starvation.
It’s December 2018 as I rewrite this post from April 2011. I decided to keep a record of how much snow my hives had to contend with during my first winter of beekeeping. Whenever they got nailed with heavy snow or rain or freezing rain and drizzle and fog and wind, anything that was drastically different from the day before, I took a picture of it and observed how the bees reacted to the changing winter weather conditions. More details on all that can be gleaned from the original comments for this post that are still intact. I’ve deleted most of the photos (well over 20 by the time it was done). Missing are the final photos showing how the hives were covered in ice from storms of freezing rain in April. The final record really drove home the reality that just about every place on planet Earth has an earlier and warmer spring than beekeepers on the island of Newfoundland. Yeah. So here are just a few of the photos I kept.
December 2018 Introduction: I’d like to delete this post or at least rewrite it and simplify it, but I’m leaving it alone because the comments are informative. Many of the comments during the first few years of this blog are informative. Things slowed down considerably after I was forced to move my hives because of unpleasant neighbours, but before that I was getting about 3,000 readers a day and discussions through comments were pretty consistent.
A leaky hive isn’t a huge concern. Most of what I thought of as leaks was probably condensation building up inside the hive because I had everything sealed with duct tape. It’s not a huge problem to find a few cracks between the inner cover and the top deep. The cracks at the top of the hive provide a little extra ventilation.
Today I don’t bother with insulated inner covers. I add a rim over the top deep to make room for sugar bricks and I put a piece of hard insulation over the inner cover. If I find moisture inside the hives, I create some extra ventilation by adding moisture quilts or some sort of ventilation box on top.
This post was written during my first winter when I thought pollen feeding was necessary, but it isn’t necessary. Pollen can help boost up a weak colony, but I’m not sure a healthy colony needs pollen early in the winter, keeping in mind that pollen stimulates the queen the lay more, which means more bees that need more sugar and honey, which means once I start feeding pollen, I have to be ready to keep feeding sugar and then sugar syrup so all the newly emerging bees don’t starve. And that’s all fine for saving a weak colony, but healthy colonies that are artificially stimulated to expand through pollen feeding can expand so rapidly that swarming can occur as early as May (which I have experienced). Which is fine if I’m ready to deal with swarms or create splits before the over-populated colonies swarm. But I have to monitor those colonies closely and make sure the queen doesn’t run out of room to lay. I also need equipment standing by so I can create those splits quickly or catch a swarm if necessary. When the bees shift into swarming-mode, they don’t mess around. It becomes their #1 priority. They act fast. Anyway, here’s the original post from 2011:
It went up to 2Â°C today and a few bees were flying around, so I quickly opened each hive and gave them what I have decided is absolutely their last feeding for the winter. I got it all on video but was by myself and didn’t have time to take any careful photos. All I got was this — Hive #1 after adding another candy cake and another pound of pollen patties:

November 2018 Introduction: This is how I used to wrap my hives. Today when I wrap them, it’s pretty much the same deal except I use 6mm (quarter-inch) mesh on the bottom entrances, and then later the top entrance, to keep shrews out, and I don’t fold any the of wrap inside the hive because I noticed it holds moisture inside the hive.
Here’s the low down on exactly how I wrapped and prepared each of our four-month-old double-deep Langstroth hives for winter:
1) Built and installed mouse-proof entrance reducers and made sure to check the hive for mice beforehand.
2) Flipped the inner cover to the winter position (with the flat side facing up) and placed a piece of hard insulation over it. The insulation has a R-7.5 rating, whatever that is. Apparently, R-5 or above will keep the condensation from forming in the hive. It looks like this before the top cover is added:
