Still haven't had a look inside, ran out of time with hay carting yesterday but did stop beside it and climb onto the roof of the ute to get a better look at the bees entering. Looks like there is pollen coming in so they should be committed to their new home.
Another thing with their choice of this trap is the entrance size, When I made the nuc boxes up I made 10 boxes, 5 bottom boards & lids so everything was interchangeable. With nucs I have been using a entrance reducer to give them a 1" opening but this trap was set without one so the entrance is 1/2" by the full width of a 5 frame nuc.
Seems the only thing I did right was the location, box is smaller than ideal, entrance is larger than ideal forgot to apply LGS yet the bees were still happy to move in.
