For me (& my chams) the banded crickets are second to none for chameleon food. These are a staple for my animals. I find them really great for gut loading & they seem to provoke a much better feeding response, than other cricket species, locust or roaches. The only other live foods i have tried, that mine seem to prefer. Are morios & blue/green bottle flies.
Only downside is the noise. I don't have problems with odours, as i don't buy too many in one go & so they are fresh & dont get a chance to stink, before being used.
