Is it me or are their more Mouse About? Mice seem to be everywhere. They have invaded my garage, under my kitchen sink, in my greenhouse, and under furniture. Mice are true Ninjas!
The little furry friends ate my garage door seal to get into the garage. The ones in the house may have come in through the dryer vent. I have since modified the vent with a screen. During a kitchen remodel, the mice seem to have sneaked into an area under my sink. I plugged that tiny hole as well.
When I see evidence of mice, it is usually tiny turds or chewing debris. I have been saving sunflower and other seeds for next year in the greenhouse. Today I saw remnants of my eaten seeds. The mice now must become airborne to reach my seed stash and can instead munch on some pet and people friendly mouse poison.
Mice carry diseases. These diseases are spread through urine, droppings, saliva, handling, and bites. Common diseases are the Plaque, Leptospirosis, Hunta virus, and lymphocytic Chorio Meningitis. All can be fatal. Mice also carry fleas, ticks, and mites that also spread diseases. Moored boats require a shield attached on the mooring lines to keep mice off the boat. Gear boxes from the shed may also have mice in them when you carry them onto your boat or into your RV.
When mice chew wiring, they can start a fire or ruin the electric in your home. Make sure that your RVs, boats, and wheelers have mouse protection around them. Mice will quickly make a home out of the foam seats, any cloth or clothes, and wiring harnesses. 
If mice are entering your home, things that eat mice will follow. Look out for snakes, and other rodent predators. If mice can get into your home so can rats, chipmunks, squirrels and … I guess cats can help but I have never owned a cat. I have watched my dogs watch a mouse run right in front of them.
Heater vents contain the perfect fuzz for Mickey and Minnie to make a nest. This is also perfect kindling for fires. If you have rope, or other material stowed away, this too can end up getting ruined. My son had a vintage stored truck seat devoured by mice. The wiring under the hood also took a beating.
Traps can certainly help catch the problem mice. The old spring type work great if the mice trip them. The stinkers have a knack of licking al of the Peanut Butter off without releasing the trigger. Then they leave little turds around the trap to make fun of you.
I have seen water traps that use a bucket half filled with water. A ramp heads up the bucket and bait invites the mice onto a collapsing ramp. This drowns the mice and contains the stink. Mice killed using poison die where they fall and can stink up the house.
The one for sure Mice trap is a sticky pad. Place these pads along areas where the mice travel. Check them daily. If the mouse steps on the pad, they are done. 
Now I know that some folks think mice are cute, fuzzy, and may need to be caught and released. Your home, your rules. For these folks, try an Ultrasonic Sound relent. The manufacturers claim that the mice will leave your home within 48 hours. Just make sur that you find the mouse highways.
