Mice

Why Mice Are a Problem

While small and easy to overlook, mice can cause major issues in Calgary homes. Here are some of the main reasons they’re a serious problem:

Health Risks

Mice can carry harmful diseases such as hantavirus, salmonella, and leptospirosis. These illnesses can spread through their droppings, urine, and saliva—contaminating surfaces, food, and even the air inside your home.

Damage to Property

Mice constantly gnaw on materials to keep their teeth sharp. They can chew through electrical wiring, insulation, wood, drywall, and even plastic pipes. This can lead to costly repairs and increase the risk of electrical fires.

Rapid Reproduction

A single pair of mice can multiply very quickly. Under the right conditions, one pair can produce up to 50 mice in one year. What starts as a small issue can become a large infestation in a short amount of time.

Contamination

Mice leave droppings, urine, and nesting materials around your home. These contaminate food, countertops, cupboards, and storage areas, creating health hazards and making your home unsanitary.

Signs of a Mouse Infestation

It’s important to catch a mouse infestation early before it spreads. Here are some common signs Calgary homeowners should watch for:

Droppings

One of the most noticeable signs of a mouse problem is the presence of droppings. These small, dark, pellet-like droppings are often found in kitchen drawers, pantry shelves, under sinks, or behind appliances and furniture.

Gnaw Marks

Mice constantly gnaw on materials like wood, plastic, and electrical wiring. You may see gnaw marks on food packaging, baseboards, walls, or even cables.

Noises

Mice are mostly active at night. Scratching, scurrying, or rustling noises—especially from attics, walls, ceilings, or behind cupboards—can indicate an infestation.

Nests

Mice create nests using shredded paper, insulation, fabric, or other soft materials. If you find small, messy nests tucked into hidden corners or storage areas, your home may have an active mouse problem.

Sightings of Mice

Seeing a mouse during the day usually means the infestation is well-established. Mice are nocturnal, but when food becomes limited or nesting areas are crowded, they may appear in daylight.

Our Mouse Control Process

Once you already have mice inside your home, it’s important not only to eliminate them but also to prevent them from returning. Here’s how we handle mouse control in Calgary:

1. Thorough Inspection

We begin with a detailed inspection to determine the size and severity of the infestation. Our technicians will:

Check all entry points, including doors, windows, vents, and foundation gaps.

Look for signs of nesting, droppings, or gnaw marks.

Inspect your attic, basement, walls, crawl spaces, and other potential hiding areas.

After identifying the source of the infestation, we create a customized treatment plan tailored to your Calgary home.

2. Seal Entry Points

Mice can squeeze through tiny openings—as small as a dime. We locate and seal all possible access points, including cracks in walls, gaps around windows and doors, and holes near plumbing or electrical lines.

Why Sealing Entry Points Matters:

Prevents Future Invasions: Proper sealing stops new mice from getting inside.

Stops the Spread: It prevents mice from migrating through walls and other areas, reducing the risk of a larger infestation.

3. Traps & Baiting

We use safe and effective trapping and baiting techniques to remove existing mice. Our Calgary technicians will:

Place traps in strategic locations, such as along walls, behind appliances, near food sources, and in attics or basements.

Use eco-friendly, targeted bait designed to attract mice while being safe for children and pets when placed correctly.

4. Rodenticide (If Necessary)

In more severe infestations, we may use rodenticides (poison) in a controlled and safe manner. We apply them only in secure areas where mice are active—well out of reach of children, pets, and non-target animals.

Why Rodenticides Can Be Necessary:

Effective for Large Infestations: In cases with significant mouse activity, rodenticides can quickly reduce large populations.

Safe & Targeted Application: We use only EPA/Health Canada–approved products and follow strict safety protocols to protect your household.

5. Ongoing Monitoring & Prevention

After treating the infestation, we continue supporting you to ensure your home stays mouse-free. We provide:

Follow-Up Visits: We’ll monitor your property to confirm no new mice have entered.

Ongoing Prevention Tips: Our technicians give practical advice on reducing future risks—such as sealing food properly, removing clutter, controlling moisture, and maintaining a clean home environment.

How do I know if I have mice in my Calgary home?

Seeing a mouse during the day often signals a larger infestation. Call for a free inspection if you notice these signs.

How long does it take to get rid of mice from a Calgary home?

Most mouse infestations in Calgary take **2–4 weeks** to eliminate completely. Initial treatment includes trap placement and sealing entry points. Follow-up visits (7–14 days later) check traps, remove captured mice, and ensure no new activity. Severe infestations may require **4–6 weeks**. Because a single pair of mice can produce up to **50 offspring per year**, fast treatment is crucial.

Can mice get through small openings in my house?

Yes. Mice can squeeze through openings as small as a dime (6mm or 1/4 inch). They commonly enter Calgary homes through cracks in foundations, gaps around pipes, spaces under doors, damaged window screens, and holes near utility lines. Calgary’s colder months push mice indoors seeking warmth. Our technicians identify and seal all entry points using steel wool, caulk, and wire mesh to prevent mice from entering or returning.
