Wondering Why You’re Seeing Mice?

It starts with a scratching sound in the walls or a few tiny droppings behind the fridge. Before long, you’re asking the all-too-common question: “How did the mouse get in my house?” The short answer? Through a small crack or hole you probably didn’t even notice.

House mice are small, curious, and incredibly resourceful. They can squeeze through gaps the size of a dime and will do whatever it takes to find food, water, and shelter. Once one gets in, you might be dealing with many mice in a matter of weeks.

Let’s break down how mice gain access, the common entry points you should check, and how to prevent future infestations.

Common Entry Points for Mice

Mice don’t need much to get in, just a crack, gap, or hole. Here are the most common mouse entry points:

• Garage doors that don’t seal properly
• Gaps around exterior doors and windows
• Cracks in foundations or siding
• Holes around gas lines and electrical wiring
• Openings near crawl spaces or basement vents
• Damaged screens or roof eaves

If you’ve spotted a mouse or signs like mouse droppings or chewed food packages, you’ll want to start sealing up potential entry points immediately. Otherwise, you’re just providing shelter to small rodents that can carry disease and cause property damage.

Telltale Signs of a Mouse Infestation

Not sure if you’re dealing with a single house mouse or a larger mouse infestation? Here are the telltale signs:

• Mice droppings (small, black, and rice-shaped) in kitchen cabinets, pantries, or under sinks
• Nesting materials like shredded paper, insulation, or fabric
• Gnaw marks on food packaging, furniture, or even electrical wiring
• Sounds of mice activity at night (especially scratching in walls or ceilings)
• Greasy smudge marks along walls or baseboards

If you’re seeing multiple signs (or if you find mice droppings in several rooms), it’s time to call a professional pest control company.

What Do Mice Eat?

One of the main reasons mice tend to invade homes? Food sources. Mice will eat almost anything, including:

• Crumbs or spilled food
• Pet food
• Unsealed pantry items
• Trash and food scraps
• Bird seed or animal feed

To prevent mice from sticking around, remove their incentives. Store food in airtight containers or metal containers, clean up regularly, and don’t leave pet food out overnight.

How to Find and Seal Entry Points

To stop a rodent problem before it grows, you’ll need to find every possible mouse entry point. That means:

1. Inspect your home exterior—especially around doors, windows, crawl spaces, and utility lines.
2. Look for small holes or cracks—remember, mice only need ¼ inch of space.
3. Use materials like steel wool, expanding foam, or caulk to seal gaps.
4. Add door sweeps and weather stripping where needed.
5. Replace damaged screens or vents.

Blocking rodent entry points is one of the most effective ways to prevent mice from coming back.

Why You Shouldn’t Rely on Traps Alone

While mouse traps can help reduce the presence of mice, they won’t fix the core issue: access. Even if you catch a few, more mice will come unless you remove food and water, seal holes found, and address the entry point.

Traps also don’t eliminate the health risks. Mice leave droppings, carry disease, and can trigger allergies, especially in children or pets.
