Multiple mice have been found in our attic before, so I know the noise. The usual solution is a standard mousetrap, which kills our “guests” – not very friendly hospitality…

How about something new?

Here is an automatic mousetrap I built yesterday. The main component is the actuator: A solenoid found in one of Vienna University of Technology’s trash containers. It is triggered by an infrared light barrier.

I caught the first mouse after just 2 hours!
