Worms as Staple Diet For B. orientalis?

[happy toad]

I am interested in keeping a group of Oriental Fire-bellied Toads (Bombina orientalis). I was wondering if it was possible to feed earthworms as the staple rather than crickets, because I really dislike crickets. I was just planning on getting worms that are packaged as bait so I don't have to bother culturing them (at least for right now), which I think is normally night crawlers here in my area.
Thanks for the help.
