Yayyyyyyyy I am so happy for you... question... were you watching activity before they moved in???
I know I should get out more, but during the last 3 afternoons, I've been working outside and my 14x12 bait BB is at eye-level in a raised location in comparison to topography (if that makes sense) and these 3 afternoons have had about 6-10 bees in and out, sniffing, flying in front of the BB before spiralling up and away. A few moments ago, I watched one rubbing her abdomen, grooming on the landing board, as well as wafting into the entrance hole. Any ideas???
Also, when the swarm came, did you see it???
Oh so excited to receive updates!!!
