Scorecard:
Jaws I in the garage next to door into the house: 4 kills, closing in on being an ace.
Jaws II in the basement hallway: 1, kills in the house itself aren't common.
KC's cat suggestion won't be of much use unless I locked a cat in the garage. They are probably still the end consumer with me being the middleman and the Jaws brothers being the hunter killers. The three mice I placed outside in the garden path were all gone this morning. Not sure if it's the free range cats or native wildlife (owl, blue jay, fox) but something is eating them.
