5 Reasons Buying a House Without an Inspection Can Lead to a $20,000 Mouse Infestation

One couple's first fall in a rural-ish home brought a $21K quote and a discount if they decided that day. They're getting a second opinion and starting with sealing and trapping. Here's why mice move in, and what to do about each one.

The weather01

It Turned Cold

That couple saw a few mice in their first few months, trapped them, and the sightings died down. Then, as winter came, they started hearing more of them in the walls. Homeowners on the forums say the same thing: temps drop, and then they hear scratching in the walls.

The fix: Do your walk-around now, before it gets colder. Seal the gaps you can reach, and set a pouch by the spots you can't. It's a repellent: mice don't like to settle near the smell.

You Live Next Door to Them

A rural home comes with fields, woods and a lot of critters around. That couple wasn't surprised to see a few mice, and you don't need to blame yourself either. Mice happen. You can't move the field.

The fix: Start with the rooms that face the outdoors: the garage, the basement, the pantry on an outside wall, and the shed. The bigger packs are sized for a full home plus an outbuilding.

The inspection03

Nobody Checked the House

They bought right before the market cooled and waived the inspection. They say they shouldn't have, but live and learn. Inspection or not, the gaps are still there.

The fix: Do your own inspection. Walk the outside of the house with steel wool and spray foam, and fill every gap around pipes, vents, the water spigot and the gas line. The CDC says a mouse can fit through a gap about the width of a pencil.

They Settle Where You Can't See

By the time that couple called someone, there were nests in the attic insulation. That's what the $21K quote was for: taking out all the attic insulation, cleaning the wood and putting in new insulation. Mice don't stay where you can see them. They settle in walls, attics and the back corners you never get to.

The fix: If the attic is already full of nests, have a pro look, and get more than one quote, like they're doing. If you're trying to keep mice from settling in, set a pouch by the spots you can't reach: behind the stove, under the sink, the corners of the garage.

Traps Don't Close the Door

They trapped the first few, and it worked for a while. Then winter brought more. A trap catches the mouse that's already inside. It doesn't close the gap the next one uses.

The fix: Keep your traps if they work for you. Close the way in too, and set pouches in the spots you can't close. There's no poison in a pouch, so nothing ends up dying in a wall you can't get to.

Any last questions?

I've tried pouches like these before. Why would these work?

These have a mineral base, not corn cob, so there's no food in the fill. They also aren't meant to work alone: seal every gap you can reach, then put a pouch in each spot you can't.

Mice chewed through the last pouches I used. Will they chew these?

We can't promise a mouse will never bite one. Here's what's in it: three plant oils in a mineral base. There's no corn cob and no food in the fill.

Do I still need to seal up my house?

Yes. Seal every gap you can reach. These go in the spots you can't, like the back of the pantry, under the sink, or in the garage.

Dryer sheets work for me. Why add these?

Plenty of people swear by them, and they may be working for you. You don't have to stop. These pouches go in the spots a sheet can't sit.

Will my house smell like peppermint?

You'll notice it when you open a cabinet. That's the point. If the smell bothers you, put the pouches in the spots you don't sit near, like the garage, the basement and the back of the pantry.

Is it safe around my dog and my kids?

Use them as directed. Keep them out of reach of kids and pets, the same as anything with essential oils.

Does it kill mice?

No. It's a repellent. It doesn't kill mice, so there's nothing dying in a wall you can't get to.

Which pack do I need?

Pick by how much of your home you're covering. BUY 1 is 12 pouches for 1–2 zones, like the pantry and one room. BUY 2 GET 1 FREE is 36 pouches for 3–4 zones, a full home. BUY 3 GET 2 FREE is 60 pouches for a full home plus one outbuilding. BUY 3 GET 3 FREE is 72 pouches for full property coverage.
