Mice Are Moving In This Winter. Here's What They're Doing to Your Home.
When temperatures drop, mice go looking for warmth, food, and shelter, and your house checks all three boxes. A mouse can squeeze through a gap the size of a dime, so those little openings around pipes, vents, foundation cracks, and garage doors are open invitations.
Once they're in, they head straight for the attic, walls, and crawl spaces. Insulation makes a perfect nest, and they'll tunnel through it, shred it, and use it as a bathroom. Mice leave droppings and urine everywhere they travel, and they can produce dozens of droppings a day.
Why that's a bigger deal than it sounds:
• Contaminated insulation stops doing its job. Tunneled, compressed, and soiled insulation loses its R-value, so your heating bill climbs while your house stays cold.
• Odors don't go away. Urine soaks into insulation and keeps smelling long after the mice are gone. It can also draw new rodents back in.
• Health risks. Droppings and urine can carry bacteria and viruses like hantavirus and salmonella. Those particles get stirred up and can circulate through your home's air.
• Wiring damage. Mice chew, and chewed wires are a real fire hazard.
The fix is a two-part job:
1. Get the mice out and keep them out. Professional treatment plus sealing up entry points is the only way to stop the cycle. Trapping alone won't cut it if they can still get back in.
2. Replace contaminated insulation. Cleaning up droppings isn't enough once urine has soaked in. Removing and replacing the damaged insulation restores your home's energy efficiency, gets rid of the odors and contaminants, and makes your home healthier and more comfortable.
Think of it as hitting reset. Once the pests are gone and the insulation is fresh, your home is protected and efficient again.
