The crunchy bugs (waxworms, mealworms, dubia roaches) have a higher risk of impaction. If you feed them to your frog, make sure they are smaller, or much smaller in size than you think appropriate. They are more easily passed that way. Crickets are a good staple from what I've read.
Make sure to use a Calcium+D3 supplement AND a Vitamin supplement about every other feeding when younger. Repashy's "Super Foods Calcium Plus" combines the two into one dust.
