Dried mealyworms--yeah, ha ha--they do act CRAZY when they see and hear that canister! I also buy black sunflower seeds at Southern States. Also, there is always a bowl on the counter and every little bit of kitchen scrap that is good for them (I printed out the list I got from here) goes into the bowl all day long. Bits of scrambled egg, hamburger, rice, greens, whatever. Plus, if you are giving them access to the outdoors, don't go overboard with the treats..make them WORK for those bugs and worms. My son filled their fenced-in winter yard (we are letting the rest of the backyard get rebuilt from their foraging) with bag after bag of oak leaves that we picked up around the neighborhood. It has kept the ground warm enough that the wormies are just fine and fat. PLUS, when the gals go back to free-ranging in the full backyard (it's just an urban backyard), the fenced-in area becomes THE richest garden plot in Virginia!
