Mice / Rodent Problem

[Account Closed]

Hello,

I have a family of mice living in the attic/walls.  They are not in the living spaces.  I had traps set in the attic, crawlspace, and exterior with limited success.  I located the the entry point and plan on sealing it but I am not sure I should trap them in the house.  Should I seal the hole and hope they don't create a new access point?  Or should I leave the hole and continue to poison and trap?  Any advice is greatly appreciated.
