My little Lillie does the biting at the pants thing....especially when people are leaving...she is a very sweet little girl...I just don't think she wants people to leave! LOL....the squirt bottle method may work or try putting pennies in a can that has a cover on it...when they start the unwanted behavior shake it hard and say NO! or...what has worked for me...roll up a newspaper and smack it on your leg and say NO! they don't like the noise...and my favorite when I am leaving...I throw and handful of cheerios on the floor and they run to get them....works every time!
