House Mice in Rialto & Fontana Homes

common house mouse

You’re sitting on the couch late at night when you hear it—scratch, scratch, scratch. Or maybe you’ve opened the pantry only to find tiny black droppings near the cereal box. That sinking feeling you get? Yep, it’s probably house mice.

Here in Rialto and Fontana, mice are one of the most common pests homeowners deal with. And while they might look small and harmless, the truth is they can cause big problems if you don’t take care of them quickly.

What Do House Mice Look Like?

House mice are little guys, only about 2–4 inches long, with soft gray or light brown fur, large ears, and a long, skinny tail. They may not look scary, but what makes them such a headache is how easily they get inside. Believe it or not, they can squeeze through a hole the size of a dime. That means even the smallest gap around a door, pipe, or vent is an open invitation.

Why Mice Come Into Your Home

Think about what your house offers: warmth, food, and safety. That’s exactly what mice are after. Crumbs on the counter, pet food left out overnight, or a leaky pipe under the sink is enough to convince a mouse your home is the perfect place to settle down.

In Rialto and Fontana, mice don’t just show up in winter—they’re active all year long. But in cooler months, you’ll definitely notice them more as they look for warmth inside.

Where Do They Come From?

Most mice start outside in fields, bushes, or even cluttered sheds. Once they sniff out food or warmth, they’ll sneak inside through tiny cracks in your foundation, gaps under doors, or openings around plumbing. Once in, they build nests in quiet spots like walls, attics, and behind kitchen appliances. That’s why you might hear scratching at night but not see them during the day—they know how to stay hidden.

Why You Don’t Want Them Around

At first, you might think, “It’s just one little mouse.” But here’s the problem: one mouse usually means more. They breed quickly, and before you know it, you’re dealing with a full-blown infestation. And aside from being creepy to see, mice can:

• Contaminate food and counters with droppings and urine

• Chew through wiring and insulation (creating fire hazards)

• Spread bacteria and diseases like salmonella

• Keep you up at night with scratching in the walls

Not exactly the houseguests you want sticking around.

How to Get Rid of Mice for Good

Sure, you can set a trap and catch one or two—but that won’t solve the bigger problem. Mice are smart, cautious, and usually hiding in more than one place. That’s why professional rodent control is the best solution.
