If you need your lizard to stay away from you, then try to avoid getting too close to him. This can sometimes be the case if they are angry. When you get closer than 2 feet (61 cm) to your lizard, he may start hissing. If you continue to approach him, then he will eventually bite you. When this happens, you should immediately back up and leave the area. Don’t worry, though. Your lizard won’t hurt you unless he feels like he has no other choice but to defend himself.
