i usually buy 15 crickets a week then keep them in a container separate from where i keep my chameleon. every feeding time i would just put my chameleon in the cricket's container and let him eat. after he is done i would take him out. i'm starting to dust my crickets now and i'm just wondering can i dust all my crickets then put them in the container or do i have to take some crickets out then dust them right before feeding time. 15 crickets last me about a week so i don't know if it is ok to have dusted crickets for a week.
