crickets are ok occasionally, once in a while you can do dubia, crickets, hormworms, wax worms, butter worms, mice ( no more then once a month), but keep pac food and nightcrawlers as a staple. pacman food only available for ordering from =TOP= of PacmanFood.com it is a powder that you need to mix with water

P.S. pet store people don't necessarily know what they're talking about

Crickets and dubia roaches are very commonly used as staple foods. If dusted with a supplement every 2-3 feedings they are fine and present low risk for impaction.
There's nothing wrong with pacman food or nightcrawlers; I use nightcrawlers as the primary food for my pac. But they aren't the only acceptable staple foods.
