I'm another who swears by Dubias... I keep all sorts of Herps and have not had to buy a cricket in months since my Dubia colony got up and going. They don't stink like crickets do... They are easy to handle... They don't chirp... and they breed like crazy when you keep them warm. IMO the best feeder for bug eating herps.

As for crickets... When I was raising them I found the survival rate stayed up when I had extra ventalation. It's like the smell of crickets...kills the crickets. I cut an openings in the sides and the lid to ensure a nice pathway for cross ventalation.
