Whenever I talk about foundationless frames, they always have a starter strip in them. A starter strip is where the bees begin (or “start”) to build comb in a foundationless frames.
Foundationless frames are used for all kind of reasons. And that little strip of plastic isn’t going to pollute the honey or the bees. The bees will encounter considerably worse things in their environment while foraging. That’s one of the reasons why there’s really no such thing as organic honey.
It’s probably a better idea to securely glue in the starter strip with wax or whatever than jamming it in like I do in the video. I shot this video on the spot only as a quick demo.
