The Sentinel Roll™ is three sheets of premium paper towel, rolled tight and placed in the gaps of your home. If a mouse squeezes through, the paper is chewed — and now you know which hole they're using.
As seen absolutely nowhere, and yet everywhere it matters
The problem
Mice are silent, nocturnal, and shameless. By the time you see droppings, they've already picked their favorite entrance. Traps tell you a mouse died. Cameras cost a fortune. What you actually need is a simple, honest sensor that says: "someone came through here."
The average home has more mouse-sized openings than the homeowner could ever count. Which one is active? You have no idea.
You'll never catch them in the act. But the paper towel is on duty 24/7 and never blinks.
Smart sensors, exterminators, ultrasonic gadgets. All you needed was to know if and where.
How it works
Take exactly three sheets of the included premium paper towel and roll them into a firm, confident cylinder.
Tuck the roll snugly into any suspicious gap, hole, or crack around your home's perimeter.
If the paper is chewed, shredded, or gone — a mouse is using that hole. Mystery solved.
