Dryer sheets, mint, traps... nothing scares them away. You have to entice them with an alternative somewhere else or just kill them when they get there. I had mice in my camper and I was able to watch them not give a shit about any of the internet solutions... all I had to do was clean out the traps regularly until the family was gone. Sold the camper before another one moved in.
To clean up the mouse mess fast
Take a 5 gallon pail
Add 6 inches of water
A little wood ramp from the floor to the top of the pail
Run a .5" rod thru a plastic water bottle or beer can ( I just wanted to say beer )
Lay the .5" wood rod across the top of the pail
90 degrees to the ramp
Add a touch of peanut butter on the bottle
The mouse will jump from the ramp to the bottle for the butter & good bye you little MFR
I got close to 20 in 1 nite at my old house
They chewed thru my car cover
bye bye
For people using live traps & releasing them
Mice will find their way back unless you travel at least half a mile
