I actually follow a guy on youtube who paints / coats his plastic sheets with melted wax for that reason. He actually does it pretty thick so the bees can chew it thin and then use the extra to build the cell walls. He used to paint, but he has like 60 hives or something like that, so now he melts the wax in a really large pot with water in it, the wax floats to the top and he just dips the sheets into the wax and lets them coat themselves.I am still seeing too many small hive beetles, some of which are hiding under the Swiffer dry sheets!
I ordered a clear hive cover for each of the hives (2) as well as a small hive beetle trap for each hive. Hopefully those will do the trick!
I also melted down some "old" beeswax I had removed from the hives earlier in the year and "painted" it onto a couple of those black plastic sheets in a few frames that I have. I want to see if that makes them more acceptable to the bees or not.
How are everyone else's bees doing?
