Mealworms and wriggly little foods, meaning that if they aren't placed in a suitable livefood feeder like the Komodo Mealworm dish, they can escape and end up mixed with your reptile's substrate, risking infections and potentially causing impaction if your reptile consumes substrate while trying to eat stray mealworms.
The Komodo Mealworm dish features a higher and more concave lip, giving the dish higher walls that the mealworms won't be able to wriggle their way over, but leaving plenty of room for your reptile to get stuck in to these tasty treats.
