Mice Are Invading Your Home?

Every day you wait, these destructive pests multiply and spread disease. Here’s what’s happening in your home right now:

House Mice

Contaminating Food & Surfaces

Mice invade kitchens and pantries, contaminating food and surfaces with droppings and urine. They carry bacteria and viruses that can make your family sick.

⚠️ Health Risk: Immediate contamination threat

Field Mice

Chewing Wires & Insulation

Field mice enter through cracks and holes, chewing on wires, insulation, and wood. This can cause electrical fires and costly property damage.

⚠️ Property Damage: Wiring & insulation ruined

Deer Mice

Spreading Hantavirus & Allergens

Deer mice are known carriers of hantavirus and other dangerous diseases. Their presence poses a serious health risk to your family, especially children and pets.

⚠️ Infestation Growth: Doubles every 2-3 weeks

The Real Cost of Waiting

You Heard Scratching in the Walls. Here's What's Really Happening

It started with a sound. A scratching in the wall at night. Maybe some droppings by the stove. Maybe a bag of flour with a small hole in the corner.

You put down a trap. Maybe caught one. Problem solved.

Except a house mouse reproduces every 21 days, with litters of 6–8 pups per birth. The mouse you caught was one of dozens. The ones you didn’t catch are breeding right now — in the warm insulation inside your walls, in the space behind your dishwasher, in the gap between your kitchen cabinet and the subfloor.

By the time most homeowners call us, there are already 30–50 mice in the home. We have seen GTA homes with over 200.

Why Poison Baiting Alone Fails Completely

Rodenticide bait stations are a tool but used without exclusion sealing, they are a treadmill. The mice inside your home die. The mice outside your home enter through the same unblocked gap. Two weeks later. same problem. Same traps. Same cost.

Mice do not go away on their own. They expand into available space and food supply until something stops them.
The only permanent solution is three things, done in order:

Pestisect does all three — in that sequence — every time.

Mice Cause Trouble

The Damage You're Not Seeing

Mice are destructive pests that can create big problems for your home and family.

Mice gnaw constantly to wear down their continuously-growing incisors. Gnawed wiring inside walls is a documented fire risk. Ontario fire investigators confirm rodent activity as a cause in residential structure fires.

Mice nest in loose-fill and batt insulation, compressing and contaminating it with urine and feces. Contaminated insulation in a Brampton or Toronto home means replacement and the health risk of airborne hantavirus during removal.

Mice contaminate far more food than they consume — urinating constantly as they travel, leaving an invisible contamination trail across every surface they cross.

Every gap a mouse uses to enter your home is also a point of entry for cold air, moisture, and other pests. Sealing them is a structural and energy efficiency improvement as well as a pest fix.

Food Contamination

Mice contaminate food with their urine, droppings, and hair, spreading diseases.

Disease Transmission

They can transmit diseases like Hantavirus, Salmonella, and Leptospirosis.

Food and Water

Crumbs, pet food, and accessible pantry items are a major draw.

Warmth and Shelter

As temperatures drop, mice seek shelter indoors.

Nesting Materials

Shredded paper, fabric, and insulation are used for nesting.

Easy Access

Mice can squeeze through tiny cracks and holes in your home's foundation.

Attics and Basements

Dark, cluttered, and undisturbed areas are ideal for nesting.

Wall Voids

Mice travel and nest within the walls of your home.

Behind Appliances

The warmth and hidden nature of these spaces are attractive to mice.

Storage Boxes

Cardboard boxes filled with clutter provide both shelter and nesting material.

Did You Know?

A single pair of mice can produce hundreds of offspring in a year, leading to a major infestation in a short amount of time.

Prevention Tips

DIY Prevention Tips (Until We Arrive)

While waiting for professional treatment, here are immediate steps you can take to reduce mouse activity in your Toronto home:

⚠️ Why DIY Methods Often Fail

DIY traps only catch a few mice. The rest of the colony remains hidden, continuing to reproduce. Professional treatment is necessary to eliminate the entire infestation and seal entry points to prevent their return.

🔨

Structural Maintenance

Repair damaged screens on windows and vents

Inspect your foundation for cracks

Keep your garage door closed

Check for gaps around pipes and utility lines

🔍

Monitor & Inspect

Check for droppings, especially in pantries and under sinks

Look for gnaw marks on food packaging and furniture

Listen for scratching sounds in walls and ceilings

Use sticky traps to monitor activity

🧽

Immediate Cleanup

Clean up spills and crumbs immediately

Store pet food in sealed containers

Store garbage in sealed containers

Dispose of garbage daily

💧

Eliminate Water Sources

Repair leaky faucets and pipes

Keep sinks and floors dry

Increase ventilation in basements/attics

Fix moisture problems immediately

🚪

Block Entry Points

Seal cracks and holes with steel wool and caulk

Install door sweeps on exterior doors

Cover vents with fine mesh screens

Weather-strip doors and windows

Testimonial

What GTA Homeowners Say About Pestisect Mice Control

I had mice every winter for four years. Every fall I’d buy bait, catch a few, and it would slow down. Then back again. Pestisect came out, found 11 entry points on my Toronto home — I had no idea — sealed every one, and I haven’t had a mouse since. It’s been 18 months. I genuinely can’t believe the difference.

Richard H.

Toronto (East York)

I run a small restaurant in Brampton. One mouse sighting and I’d be at risk with the health inspector. Pestisect came out within 24 hours, treated the property, sealed the loading dock gaps, and has us on a quarterly monitoring program. Two years in, zero incidents.

Gurpreet M.

Brampton

My Mississauga townhome shares walls with two neighbours. Pestisect explained right away that shared-wall properties need to address both units to get full results. They coordinated with my neighbour and we treated together. Both units have been mouse-free for a year.

How We Eliminate Mice

How Pestisect Eliminates Mice — Permanently

The Pestisect Mice Extermination Method

Full Exterior & Interior Inspection

We walk every inch of your property's exterior — foundation, roofline, soffits, utility penetrations, vents, garage entry, and window wells. We trace interior activity to locate nesting areas and confirm which gaps are being actively used. Most homeowners have no idea how many entry points their home has — the average older GTA home has 5–15 active or potential entry points.

Targeted Mechanical Trapping

We deploy professional snap traps at all confirmed run paths — along walls, under appliances, in the basement and crawl space. Mechanical trapping is more immediate, more controllable, and safer for households with children and pets than poison bait in living spaces.

Entry Point Sealing

The Critical Difference, This is what makes Pestisect different from a standard exterminator. Every confirmed entry point is sealed using professional materials that mice cannot chew through: galvanized steel mesh, metal flashing, hydraulic cement, copper mesh, and polyurethane caulk. We don't use foam insulation or basic caulk — mice chew through both in hours.

Population Confirmation

Traps are monitored until we confirm the population inside the home is eliminated. Final permanent sealing is completed only after we are confident no additional mice remain inside.

Prevention Guidance

We provide specific, property-level prevention recommendations — garbage and compost placement, wood pile clearance from the structure, vegetation management, and maintenance items (damaged vents, soffit gaps) to address on your own or with a contractor.

Mice Exterminator Serving All GTA Homes and Businesses

Best Mice Exterminator in Toronto

Toronto's combination of aging housing stock, extensive underground infrastructure, and urban density makes it one of Ontario's highest-risk cities for mouse infestation. Older Toronto homes in East York, Scarborough, and the downtown core have numerous potential entry gaps from decades of wear. Construction activity throughout Toronto also displaces established mouse populations into residential streets.

Our Toronto service covers all neighbourhoods: Downtown, Etobicoke, North York, Scarborough, East York, the Beaches, Junction, Roncesvalles, and all surrounding areas.

Best Mice Exterminator in Brampton

Brampton's construction boom has dramatically increased rodent displacement into established residential communities. As new developments break ground, burrowing rodent populations move into adjacent housing — and Brampton's high proportion of newer homes with post-construction gaps (around plumbing penetrations, utility entries, and garage seals) provides abundant entry. Brampton townhome complexes also create shared-wall spread risk.

We cover all Brampton communities: Springdale, Castlemore, Mount Pleasant, Heart Lake, Bramalea, Fletcher's Creek, and all surrounding areas.

Best Mice Exterminator in Mississauga

Mississauga's Credit River and Etobicoke Creek corridor creates natural rodent movement from conservation areas into residential properties, particularly in south Mississauga communities like Port Credit, Lakeview, and Clarkson. Fall and winter drives significant mouse entry activity across Mississauga as outdoor temperatures drop and mice seek warmth inside structures.

We cover all Mississauga communities: Port Credit, Clarkson, Erin Mills, Churchill Meadows, Meadowvale, Malton, Streetsville, and all surrounding areas.

Your Mice Extermination Questions — Answered Directly

How did mice get into my home?

A house mouse can squeeze through a gap the width of a pencil — approximately 6mm. This is smaller than most people’s thumbnail. Common entry points in GTA homes include: gaps around plumbing pipes entering the foundation, unsealed utility penetrations, gaps between the garage door and the floor, damaged or missing soffit vents, gaps where the deck attaches to the house, and worn or missing door sweeps. Most homeowners have multiple active entry points they are completely unaware of.

Is poison safe to use in my home?

We use mechanical trapping (snap traps) as our primary method in living spaces — particularly where children or pets are present. Rodenticide bait stations are deployed in contained exterior locations and void spaces where non-target animals and children cannot access them. If you have pets or young children, tell us when you book — we will design the trapping approach accordingly.

How long does mice extermination take?

The initial inspection and trap setup takes 1–2 hours. Traps are monitored over 1–3 subsequent visits (every few days or weekly, depending on activity level). Once the interior population is confirmed eliminated, exclusion sealing is completed. The full process typically takes 2–3 weeks from first visit to final seal.

Can mice come back after exclusion sealing?

If sealing is done correctly using professional-grade materials — galvanized steel mesh and metal flashing — mice cannot re-enter through sealed points. New entry points can develop over time through structural wear, storm damage, or maintenance issues (such as deteriorating soffits). We recommend a short annual check of the exterior for GTA homes where rodent pressure is elevated.

Do I need to leave during the treatment?

No. Trapping and initial inspection do not require you to leave your home. Any bait station deployment in exterior or void areas can be done with the household normally occupied.

My neighbour also has mice. Does that affect my treatment?

Yes — especially in attached or semi-detached properties. If mice are actively moving between units through shared infrastructure, treating your unit alone while leaving the neighbouring unit untreated creates continuous re-infection risk. We recommend coordinating with your neighbour and can facilitate a joint inspection.

What if mice come back after treatment?

Our mouse control treatments include a warranty period. If mice re-enter your home during the warranty window, we return to inspect, re-trap, and identify any missed or new entry points at no additional charge.

One Mouse Is Never Just One Mouse. Call Before the Colony Grows.

In four weeks, one pregnant female becomes 6–8 pups. In eight weeks, some of those pups are old enough to breed. In twelve weeks, your home has dozens of mice and a wiring damage problem you didn’t know was happening.
