Fortunately I don't have a mouse problem. And honestly I really don't mind them although I don't want them taking up residence and having a mouse family in my home. So here are some tips on how to keep them so that you aren't cleaning out mouse traps with dead critters later. That always makes me sad. So try these tips.
Place USED kitty litter from a litter box in small tubs in several places around the garage. Mice think...it smells like a cat--must be a cat - I'm outta here!.
Buy a mesh/net laundry bag that you would use for washing nylons and 5 boxes of moth balls. Put the moth balls in the bag and hang it in your garage near the door to get rid of mice, birds, and bugs. Moth balls also repel snakes
To prevent mice from gaining entry to your garage, stop up any openings with steel wood pads. Mice will not chew through these!
Sprinkle ground cayenne pepper around the garage (inside & out), and especially near entry holes. Pests don't care for the smell of it. Ants also do not like cayenne pepper.
Mice hate the scent of peppermint extract. Simply sprinkle *pure* peppermint extract on the items in your garage you don't want the mice in or on.
