Superworms Escaping Dish

[Knyx]

I have a large dish where I usually keep about four or five superworms for my leos. Although the dish is pretty tall, they still manage to get out.

I've done a few google searches and the only tip I can find is putting petroleum jelly or vaseline on the side of the dish so they can't climb out of it, but so far I've only seen this mentioned on snake or spider forums

Would this work and would it be safe for my leos?

That's too many supers just to leave in the dish. They will pile up and help each other escape. You might try changing feeding time so the leos will eat right away, also frequency so they have a better feeding response.
