How are you feeding the mealworms? Do you just toss them in the cage or put them in a bowl? I use worm dishes like these http://www.tsksupply.com/small-worm-dish/, some Leo's I never actually see eat, but the worms disappear so I know they're eating them. You could also start a colony of B. dubia roaches. Far less smell then crickets and no noise. Some of my Leos won't touch THOSE but most of them will and it makes for a nice alternate food source.
