Query: Does Not Work

NO STARS!!! These things have no effect on mice.Have an 8 x 10' bathroom with an exhaust fan. Noticed mouse droppings and urine on the floor of the bathroom directly under the exhaust fan. Plugged one of these Victor Mini Pest Chasers in the outlet of that bathroom. Cleaned up the mouse mess. Checked bathroom the next day. More droppings and urine. Cleaned up the mess again. And so on - for 10 dys! - which is a fair test, I think. But no effect. Mice still in place and all comfy-cozy above the exhaust fan in the bathroom.Next up: cheap home remedies, like a plastic container with a rag soaked in ammonia or peppermint oil or balsom fir oil, etc.
