No offense intended but this is some crazy sheet.
Why do you need to be there to use poison? I'd put out some poison and call it a day.
You could also try the bucket trap aka the Maine mousa.
Place five gallon bucket on floor. Fill half way with water. Place cardboard tube from a roll of paper towels over a thin piece of scrap wood or something similar and lay that assembly across top of bucket. Put some peanut butter on the cardboard tube. Lean a board or something against the bucket.
Rodent smells bait. Scampers up the ramp, across the board and onto the tube only to have it spin out from underneath flinging him into the bucket. Trap remains set for the next one.
Good luck. This is a great thread.
