I have rodent issues and it is between a set of floor joist. The traffic is random and thee pest inpectors have not been able to find any evidence where they are comming into our residence from outside.
The last inspector wants to know, what times the run up and down the celing and I said anywhere from the morning to the evening. So, this got me thinking if there is a sensor that can detect the moment of mice and log the time they pass the sensor, I would have more definitive information.
I do not want to open up the celing so, the sensor would have to detect movement by vibrations or passing a beam. Please do not suggest sensors that you have not had experience with I do not want to waste my time or money ordering and using them.
