Mice

Mice in SC & GA: Identification, Signs, and Control

Mice are among the most common rodents that homeowners in South Carolina and Georgia encounter. They’re small, fast, and can squeeze through tiny gaps, which makes them expert home invaders. While they may seem harmless, mice can contaminate food, damage insulation, and spread bacteria. If you’re seeing droppings, hearing scratching inside walls, or noticing chewed items, you may have a mouse problem. The good news is that early action can prevent a small issue from turning into a full-blown infestation.

‍

Mice don’t truly hibernate; their activity levels change based on temperature, food availability, and shelter. In South Carolina and Georgia, mice are most noticeable when conditions outside become less favorable, prompting them to move indoors.

• Fall temperatures cool down, and they begin searching for warmer shelter
• Winter weather makes outdoor food scarce, pushing them indoors
• Spring brings breeding season, increasing movement and population growth
• Heavy rain or flooding forces them out of outdoor nests

Mice are constantly looking for food and safe places to nest, so they often show up in homes when the weather drives them indoors.

Identification: What Mice Look Like

Quick ID

• Size: 2–4 inches long (not including the tail)
• Tail: Long, thin, and often hairless
• Color: Gray or light brown
• Behavior: Mostly active at night, but can be seen during the day if the population is high

Where Mice Hide in Homes

• Inside walls and ceiling voids
• Attics and crawl spaces
• Garages and storage areas
• Behind appliances and inside cabinets
• Near pantry food sources

What Attracts Mice to Your Home

• Pet food left out overnight
• Open trash cans or compost bins
• Clutter and cardboard storage
• Leaks or moisture in crawl spaces and basements
• Easy access through gaps and cracks

Signs of a Mouse Problem

Although mice are nocturnal and often avoid detection at the start of an infestation, they will leave clues you can spot around the house.

Common signs include:

• Small, dark droppings (usually near food sources)
• Gnaw marks on food packaging, wires, or wood
• Rustling or scratching noises at night
• Strong ammonia-like odor in hidden areas
• Nesting material (paper, insulation, fabric)

Damage & Risks Associated With Mice

Mice may be small, but they can cause serious problems once inside a home.

Common risks include:

• Electrical damage: Mice chew on wires, increasing the risk of electrical failure or fire.
• Insulation damage: Nesting in insulation reduces its effectiveness.
• Structural damage: Gnawing on wood and building materials can weaken parts of the home over time.
• Food contamination: Mice contaminate food and surfaces with urine, droppings, and hair.
• Health concerns: Mice can carry bacteria and parasites that pose health risks to people and pets.

What to Do If You Find Mice

If you spot mice or see signs of activity, the best move is to act fast and call a professional.

• Avoid handling droppings or nests.
• Keep pets and kids away from suspected areas until the home is inspected.
• Note where you’re seeing activity (kitchen, attic, garage, etc.) to help the technician locate entry points and nests.

Why DIY doesn’t work

Mice often nest in walls, attics, and other hidden areas. DIY methods may catch a few, but they won’t eliminate the colony or stop new mice from entering. The most effective solution is a professional inspection, targeted treatment, and sealing entry points.

How to Prevent Mice

To keep mice from taking over your home, we recommend implementing the following pest prevention tips:

• Store food in sealed containers
• Keep pet food stored away and don’t leave it out overnight
• Seal gaps around pipes, vents, doors, and windows
• Keep outdoor trash bins closed and away from the home
• Remove clutter and cardboard that mice might use for nesting
• Fix leaks and reduce moisture in crawl spaces and basements
