I have, but for 2 frogs I thought buying worms at the store (5 min. away) would be better and maybe worms would be fresher. Just bought new containers of wax worms and mealworms today, made sure all were alive first, found at least 6 containers of dead wax worms. Store will not check them, I don't understand why, but, my guys each had a wax worm already.
