I'm looking for information on how this bee trap was used. I don't know if it was used inside the hive to keep the queen in one place or if it was meant to trap a queen outside the hive.
The middle hole has a sliding metal door:
Beneath each outer hole is a cone shaped wire screen, it's difficult to see but there is a hole in the bottom of the cone that is about 1/4" diameter:
Thanks for taking a look.
