I am curious as to the size of interest in Warre keeping in Washington state. So just a rough survey type of thing. Washington state- Do you keep Warres and how many do you normally have?
I have to admit, Tel, I haven't seen a better swarm "attracter" then an empty used Warre. Nothing better then going to open a dead out hive to clean it and being surprised by a swarm that moved in.
I've got no option but to sell you all for scientific experiments. Or a tiny ad:
