redworms and nightcrawlers are great foods i use them in my rotation of foods.. crickets are what you should use as a dusting food item. i wont feed my frogs mill worms.wax worms are a treat due to its so high in fat content. rotate your food items to offer differnt meals.. i do crickets when dusting whice i alternate weekly..then fish..then worms..if they dont take item..then they will the next day.no trouble with redworms or nightcrawlers there healthy and cheap.becarefull when tweazer feeding the frog will take iem hard and fast.. rounded tip and rubber covered are great..hope this helps..enjoy your feeding time
