Weird, my frog lunges in the air at them when I tong-feed roaches! Of course, I trained him with the tongs using crickets and have since moved to dubia roaches.

Maybe it's how you are holding them with the tongs? I knock the dubia on their backs in the plastic cup I use to dust them, and pick one up by one of its back legs, not by its rear end. Then I dangle it in front of Jimmy and he usually scoops it up very quickly. It seems the roaches are stunned enough to not try and hold onto the tongs, but aware enough to squirm around until he snatches them up!
