For those of us who feed our geckos crickets no other object has made quite as big of a difference as having a medium sized piece of cork bark in the cage. Prior to purchasing one, the crickets would often times congregate around the lizards den possibly stressing him out or worse yet biting him. Upon placing a good sized piece of cork bark in the cage all the crickets now congregate around the piece of wood on the opposite end with a few that will roam around the tank. By using this method I have rarely ever had to remove excess crickets the lizard did not eat because 9 times out of 10 they would stay on the opposite end of the cage and the gecko often times would just head over to the piece of bark if he was hungry.
