This is the time of year mice are looking to find shelter for the winter. I've found chocolate to be the best bait with peanut butter second. LOL the grand prize is Peanut Butter Cup candy. Snap traps are the most humane. Clean up all food/pet food and set traps in dark places, against walls, etc. The little guys can get in 1/4 inch spaces so it is very hard to fill all the entries.
