I'm just curious to find out how many folks are using hive wraps in their bee yards as part of their overall Integrated Pest Management plans. I began using hive wraps last year when I started selling them in my area to see if they really accomplished what NOD said they would. I had read and talked with other beekeepers on the subject of wraps to get the idea that most in this area were not wrapping hives. In order to investigate the impact, I used wraps on half the hives in one beeyard and the other half not wrapped. I did the same in another beeyard with a very different landscape. In almost every case, the wrapped hives came out much more healthy in the Spring than my non wrapped hives. in general. Having said that, I did lose one hive that was wrapped, but I believe that was due to mites, not environmental issues. In comparison, I noticed the wrapped hives had no "weeping" issues here moisture running down the sides of the hives leaks into cracks between boxes. Also, in general observation, I could see that wrapping of any kind also keeps wind from blowing through cracks and crevices in the hive, further protecting the hive from freezing winds and windblown moisture coming at the hives almost horizontally rather than vertically as a low wind snow or rainstorm might produce. Furthermore, the bees in all but the one wrapped hive all had significantly higher Spring populations than did the non-wrapped hives. I'm not claiming that wraps had everything to do with that, it's just a general observation over time but it seemed relevant. This will be my second year of personal use and this time I intend to wrap all my hives save for a couple.
