I just finished an extensive renovation of a foreclosed house. I know it had mice problems based on all the droppings under the cabinets when removed. I thought the mice problem was gone since I haven't seen any evidence of mice during the renovation. I moved in just over a week ago and left a half eaten bag of chips out Friday night. It was shredded by a mouse by morning. I bought and put out some snap and glue traps. Sunday morning I had two mice caught. No more mice caught last night.
How do I know I don't still have more mice? Are any remaining ones now smart enough to avoid getting caught? I am thinking about leaving some food out and see if it gets disturbed. (The house has all new siding, windows, doors, and sofitts/eaves so should be no more holes.)
