No idea where they came from, but ball pythons do NOT eat crickets.It's not normal for unwelcome critters to ride in on things you're adding to the enclosure. Be glad that it's only crickets for the time being and going forward keep better tabs on where your decor comes from and what you're adding to the enclosure.
Back on topic - I'd get rid of them. If that includes changing out the bedding or decor, then that's what you'll need to do. They're probably harmless, but that's not the point.
