Can't get hatchlings to eat mealworms

[Visionist]

So far only one of my hatchlings will eat mealworms. The other three will only eat crickets. This is a problem because I don't really have much access to crickets so I can't feed them as a staple, only as a supplement to mealworms. The parents of these geckos eat mealworms fine.
What can I try to do to get these little guys to eat mealworms?

I dig out freshly shed worms, cut the head off and squeeze some juice out and put it to their lips.... normally takes a second or two to be eaten lol.
