I usually just dump the food in for my toads in the terrarium with them, from crickets to worms and roaches. Even adult dubias are fair game. They chase them down and gobble them down. When I caught my toads I kept them in a small empty ice chest, and left food in for them overnight the day of, and it disappeared, so that kind of unwillingness to eat is somewhat worrying to me. I would try leaving in the crickets, since they're easy to keep track of. You could even add more than 2. Good luck. Also, how did you force feed the toad?
