BenFramed, I purchased the beetle jail from amazon. I use apple cider vinegar to attract and drown the beetles. The jail fits snugly between the frames, no need to make additional room. The cider I used evaporated in about a week. I placed 3 jails in one hive and the traps did catch beetles. Currently at my apiary, the beetles are few in number this last part of August. I am not sure why? Drought, maybe? Limed soil?
