Yea if they were active holes they would work no doubt. I have confidence in your cages don't get me wrong if a job needs a cage used 95% of the time yours are first ones I grab. I've got 3 of your cages out and another 3 of a different brand baited set. Badgers they are so much on the move with their hunting holes. I've yet to find one that their actually living in at the time. This job biggest property I've done a job on by far and tons of holes didn't want put all my eggs into just cages and don't have enough to cover all them. If it was active living under a building etc would be cages job for sure.

It did take a while for the lady to catch up with the one she had as, like you say, he had a bunch of holes and moved around. I guess she just keep putting dirt in part way in some of the holes and waited for a hole to get freshly dug out. Does sound like a lot of work.
