Why Are Mice Invading Your Home — and How Can You Get Rid of Them? | November 10, 2025

One morning: tiny black droppings near the fridge. One evening: a faint rustling in the walls. What if your home wasn’t entirely yours anymore? Many people in France have lived through this scene — like something out of an animated movie (minus the cute factor). Mice sometimes invite themselves in without warning. But why do they choose your house? And more importantly, how can you politely convince them to move out? Here’s your guide — no panic, no cruel traps.

A Cozy Shelter from the Cold

As soon as temperatures drop, mice go looking for a warm place to hide. Like us, they avoid the cold, drafts, and dampness. Your home — with its insulated walls and cozy rooms — seems like paradise to them. They don’t need much: a bit of warmth, a dark corner… and boom, they’ve moved in. It’s like you left out a hot water bottle and a blanket next to a 24/7 open hotel.

Your Fridge: A Gourmet Buffet

Mice aren’t picky, but they do have a great sense of smell. An open bag of pasta, a few crumbs under the table, or a half-closed bag of cat food? That’s a feast. They can detect food smells from several meters away and won’t hesitate to explore every nook and cranny. Remember: what you forget, they’ll find!

Sneaking In Like Tiny Spies

They don’t need a wide-open door to get inside. A 6-millimeter gap is enough! Picture a small coin — if a mouse can get its head through, the rest follows easily. Under the door, behind furniture, along pipes… they exploit every crack. Even the tiniest wall fissure can become a rodent highway.

Clear Signs You’ve Got Company

Before thinking about solutions, you need to confirm they’re actually there. Here are the most common clues:

  • Small black droppings, rice-shaped, often near food or in corners.

  • Nocturnal noises — scratching or tiny squeaks behind walls or ceilings.

  • Nests made of paper, fabric, or foam, hidden away.

  • Gnaw marks on wires, cardboard boxes, or baseboards.

Natural Ways to Send Them Packing (Stress-Free)

Good news: you don’t need toxic products or dramatic scenes. There are simple, gentle, and effective ways to restore peace.

Seal the Gaps

Start by inspecting your home for all potential entry points. Block holes using steel wool, caulk, or fine mesh. The goal? Make your house as sealed as a jam jar.

Clean Like a Pro

Regularly sweep up crumbs, take out the trash, and store food in airtight containers. Don’t forget pet bowls. A clean home with no food lying around is far less tempting to rodents.
