Although many people view mice as the adorable animals and heroes that they are (Mickey & Minnie? Mighty Mouse anyone?), there are far more people who view them as disgusting pests that must be eradicated at all costs. Growing up in the rural South, I looked on more than once as my dad chased field mice out of our two-car garage with a broom (killing them in the process more often than not). I also had the misfortune of finding little mice dead in a trap that had done its job too well, and too soon. However, though mice seem harmless, their presence in your living space — including the garage — can sometimes cause health and emotional problems for human dwellers. Left to their own devices, mice make nests in wall insulation, gnaw through electrical wiring, and are highly unsanitary.
If you suspect that you have mice dwelling in your garage and you want them out, now, there are a multitude of ways to get rid of them, most of them inhumane. According to about.com, for example, “You can lay traps with taut springs to snap off their heads, or lay poison…If you are serious about getting rid of mice in your garage, you will need live mousetraps, mouse repellent spray, cheese or peanut butter, a dog who hates critters, or a hungry cat. You might try hot pepper sauce, laundry detergent, caulk, garden sprayers, patching compound, scrap wood, or an ultrasonic mouse repellent.”
You might also try not harming another living thing, instead. The tried and true trap and release method is more kind to the animals and less dangerous for kids to boot. Another relatively easy way to get rid of the mice causing you so much distress is to un-clutter your garage. Mice are incredibly playful and love to climb, hide in dark corners, and nest in soft things. If you clean up your act in the garage — store everything in plastic — odds are your mice problem will solve itself.
