Seems like I have a mouse problem in the crawl space. We hear chewing coming from the hvac duct register in the floor and some debris on a nearby window sill. House is new with a sealed crawl space but I guess they found a way. I haven't been under there yet due to a physical issue.
I wanted to know if ya'll have tried any of those plug-in ultrasonic repellent devices and if they worked?
Thanks
