Keeping Mice Out of Your Home
Every fall, mice gravitate from their outdoor world towards buildings, seeking shelter for the winter. Mice do not hibernate; they remain active all winter.
Why my house? Mice like to make their winter home close to a food source and build their nest in quiet areas that are free of human activity and predators.
The spaces behind walls are a favourite. They get in through the smallest of cracks in your building. Also, attics are good spots for them, as there is plenty of insulation that can be used for nesting material there. And you don’t hear them scurrying about. They simply scale up the trees and branches that are touching your house and find their way in.
Preventing them from entering your domain in the first place. Every fall, check the exterior of your house. Look for possible points of entry and remember a mouse can squeeze through the tiniest of cracks. Here are some things to do:
- Repair damaged screens.
- Check exterior door sweeps and install new ones so there is no gap between floor and door.
- Place some sort of screening on exhaust vents.
- Prune any branches that are touching your building.
- Check caulking around windows and door frames and patch if necessary.
- Seal cracks and holes outside the home. Check where utilities and pipes enter the home.
- Repair loose mortar and weather stripping.
Eliminate food sources
- Store pet food and bird food in airtight containers.
- Dispose of garbage daily.
Eliminate hiding spots
- Store firewood away from the house.
- Keep garages and carports clutter-free.
Make your house unwelcoming
- Install mouse bait stations inside.
- Use mouse traps in areas of activity.
- Repel mice by using an ultrasonic device.
