Hi all, On 9 January Garrett Dodds asked about the pros and cons of Pierco frames. I first tried Pierco frames about a decade ago. They have performed extremely well, but for the first couple of years I found that bees could enter between the 2 layers of plastic that form the end bars. When the frames were pushed together bees were trapped, and would be dead on next hive inspection. As the years passed wax has accumulated in the spaces so bees can no longer be trapped, thank goodness. I disliked leaving bees in plastic prisons after working hives. I wonder if the model for Pierco frames available now excludes bees from end bars? Cheers, Barry Donovan, Lincoln, New Zealand.
