They are fantastic because they are so high in calcium but you really still need to mix it up with other feeders that way none are more than 20% of their diet.
They aren't recommended for everyday feeding. Maybe once a week or for females before and after egg laying or life barriers. Your staple food is preferred silkworms, crickets, and Dubai roaches.
I have a variety of feeders, including small hoppers, locusts, meal worms, wax worms and crickets were his staple diet but unfortunately he's gone off them and will no longer eat them, although I am still trying to get him back to eating crickets, which is proving to be rather difficult
