text: I don't think  the shrews are going to bite your grandchildren unless they are catching the shrews and handling them.  They would probably not be able to catch one.  When was the last time you were bit by a mouse in your house!  They are not going to attack or anything...they are going to try to avoid you and much as you would like to avoid them.  Try to find where they are getting in and block the entrance. Put out Sherman live trap, this trap does not kill them, catches them so you can relocate them far from your home.\n\nhttp://www.shermantraps.com/
