What size crickets are you buying? Beardies should be able to eat all 500 in two weeks easily. They cant die when they are already dead
BTW, to those who hate cricket smell, if your crickets smell, your doing something wrong. I buy thousands at a time and have never had a problem with smell. Its all about diet.
its more than diet matt.
as far as feeders go crickets are the stinkist things period. even the box they are shipped in stinks! i usually had 4k at a time roughly
