You still have to dust the insects, also i'd avoid feeding superworms they can cause fatty liver disease. Its best to only feed them as a treat, maybe once a week or twice a week and only 2-4 max and only for adults at least. They have pretty much only fat.
For actual staple feeders you can use silkworms, crickets, dubia roaches, calciworms or redrunner/turkish roaches.
If you dust worms with only calcium or any insects with only calcium your beardie wouldnt be getting enough vitamins it needs.
Preferably you want multivitamins and calcium supplements, i use the kind by reptical, calcium needs to be dusted on insects 5 times a week with multivitamins on insects twice a week.
