How to Get Rid of Mice and Rats in Your Home

Recognizing the warning signs of mice and rats — and understanding your control options — helps you decide when DIY steps are enough and when professional rodent control is the better path.

Published April 16, 2026

Mice and rats can cause significant problems in homes and commercial buildings. They may damage belongings, contaminate surfaces, gnaw through materials, and establish nests in concealed spaces. You might first notice droppings in a cupboard, scratching sounds inside a wall, or damage to items stored in a basement or garage. Recognizing these warning signs can help you determine when action is needed.

Getting rid of rodents requires more than dealing with the animals you see. The right approach depends on the extent of the infestation, the layout of the property, and the conditions that allow rodents to remain there. Traps and appropriate repairs may help with limited activity, while persistent problems can require professional treatment.

AM Pest Control provides rodent control services for residential and commercial properties across the Greater Toronto Area and surrounding Ontario communities. Understanding the signs of an infestation and the available control options can help you decide how to address the problem.

Signs of a Mouse or Rat Infestation

Rodents are often active in concealed areas, which means their presence may become noticeable before you see an animal. Droppings are a common warning sign and may appear near walls, cupboards, storage spaces, or other areas where rodents travel. Gnaw marks on packaging, furniture, and building materials can also indicate activity. Scratching or movement sounds inside walls and ceilings may suggest that rodents are using enclosed spaces. You might also discover shredded paper, fabric, or similar materials collected in a hidden corner. In commercial premises, damaged packaging or signs of activity near stored products can indicate a problem that needs attention.

Mice are smaller than rats and can squeeze through narrow openings. Rats are generally larger and may cause more substantial damage to certain materials. However, droppings and gnaw marks alone do not always establish which species is present. Pay attention to whether the evidence appears in one isolated location or across several parts of the property. Widespread signs or repeated sightings may indicate a more extensive problem than a single encounter.

Why Do Mice and Rats Enter Buildings?

Rodents seek food, water, shelter, and protected places to nest. Buildings can provide these resources throughout the year, particularly when outdoor conditions become less favourable. Accessible rubbish, exposed pet food, and poorly maintained waste areas can attract rodents. Structural openings around doors, foundations, pipes, and vents may then provide opportunities to enter.

Once inside, rodents may settle in basements, attics, garages, wall cavities, or other undisturbed locations. Sheltered spaces can make an infestation harder to detect. Clutter, unused equipment, and stored materials may provide hiding places where rodents can remain undisturbed. Outdoor conditions, including accumulated debris and accessible rubbish, can also contribute to activity around a property.

A building does not need to be visibly dirty to experience a rodent problem. Even well-maintained properties can have gaps or concealed spaces that rodents use. Identifying the likely contributing conditions helps determine what should be addressed during control and prevention.

Effective Ways to Get Rid of Mice and Rats

The appropriate response depends on the location and severity of the infestation. Begin by examining accessible areas for signs of activity and noting where evidence appears. Avoid reaching blindly into cavities or dismantling walls and ceilings to investigate unfamiliar noises.

Sealing suitable openings can help reduce opportunities for rodents to enter. Inspect accessible gaps around exterior doors, foundations, pipes, and utility lines, using appropriate materials for the particular opening. Repairs should not obstruct necessary ventilation or drainage. If rodents may already be inside a wall or enclosed space, consider the situation before sealing an opening.

Traps can help manage rodent activity when selected and positioned correctly. Follow the manufacturer's instructions and place them where children and pets cannot access them. Check traps as directed and handle captured rodents according to applicable safety guidance. If activity continues, additional animals or concealed nesting areas may be involved, making a broader assessment useful.

Rodenticides require particular care because misuse can harm children, pets, wildlife, and other non-target animals. Follow product labels and applicable requirements, and prevent unintended exposure. The suitability of a treatment may also depend on the building's occupants and activities, especially in properties where food is prepared or stored.

Cleaning contaminated areas is another important consideration. Avoid sweeping or vacuuming dry rodent droppings because contaminated particles can become airborne. Follow public health guidance for appropriate protective equipment, disinfection, and disposal. Extensive contamination or waste in inaccessible spaces may require specialized assistance.

These measures can help address certain rodent problems, but their effectiveness depends on the circumstances. Persistent activity, repeated sightings, or evidence in several concealed locations may warrant professional rodent control.

How AM Pest Control Handles Rodent Problems

AM Pest Control provides rodent control services tailored to the circumstances of residential and commercial properties. The process begins with an assessment of the reported problem and the areas that may be affected. The findings help determine an appropriate treatment approach based on the nature of the infestation and relevant safety considerations.

Treatment requirements can vary considerably between properties. A residential home may present different challenges from a restaurant, warehouse, office, or retail premises. Building layout, access to affected spaces, stored products, and ongoing business activities can all influence the approach. After treatment, prevention advice can help property owners understand any conditions that may require further attention. Recommendations depend on the findings rather than following an identical approach for every building.

Customers should discuss the proposed treatment, its scope, and any recommended follow-up arrangements with the company before booking. For more information about the available service, visit the AM Pest Control rodent control page.

Rodent Control for Residential and Commercial Properties

Rodent problems can affect properties in different ways. In homes, mice and rats may damage belongings, disturb occupants, and create concerns about contamination. Discovering activity in a living space can be particularly frustrating when the source is difficult to identify.

Rental properties and condominiums may involve additional coordination. Tenants may need to notify their landlord or property manager, particularly when the affected areas include shared spaces or when building maintenance could be contributing to the problem. Clear communication can help establish which areas require attention.

Commercial properties face their own challenges. Restaurants and food-related businesses may need to consider food safety and operating requirements, while warehouses and retail premises may be concerned about stored products and property damage. Offices and other workplaces may also need to address rodent activity without creating unnecessary disruption.

AM Pest Control serves residential and commercial customers. The appropriate service depends on the type of property, the reported activity, and the requirements identified during assessment. Customers can discuss these circumstances directly with the team before arranging service.

Rodent Control Pricing and Guarantee

The cost of professional rodent control depends on the property's circumstances and the treatment required. The size and layout of the affected area, the extent of activity, and the nature of the work can influence the proposed service. AM Pest Control offers competitive pricing. When requesting a quote, explain the problem and provide relevant details about the property. Ask what the proposed work includes and whether additional charges could apply if further treatment becomes necessary.

The company also advertises a full guarantee. Before booking, request the written terms and confirm the duration, coverage, applicable conditions, and process for requesting support. It is also worth clarifying whether follow-up visits are included in the quoted price or arranged separately.

Understanding the service and its conditions in advance makes it easier to compare options and know what to expect. The specific terms should be confirmed directly with AM Pest Control rather than assumed from a general description.

What are the common signs of mice or rats in a house?

Common signs include droppings, gnaw marks, scratching sounds inside walls or ceilings, damaged food packaging, and nesting materials. Repeated sightings or evidence in multiple areas may indicate ongoing rodent activity.

Why do mice and rats enter homes?

Mice and rats enter buildings in search of food, water, shelter, and nesting spaces. Small gaps around doors, foundations, pipes, and utility lines can provide entry points, even in well-maintained homes.

Can mice and rats get inside through very small gaps?

What attracts rodents to a property?

Accessible rubbish, uncovered food, pet food, poorly maintained waste areas, and sheltered spaces can attract rodents. Reducing access to food and addressing potential entry points can help make a property less inviting.

Are mice and rats dangerous to have indoors?

Rodents can contaminate surfaces and stored food, damage belongings, and gnaw on certain building materials and wiring. Droppings and nesting materials should be handled carefully using appropriate public health guidance.

Should I use traps or rodent poison to get rid of mice and rats?

The right option depends on the situation. Traps may help with limited activity when used correctly. Rodenticides require particular care because they can harm children, pets, wildlife, and other non-target animals if misused.

How can I prevent mice and rats from returning?

Seal suitable openings, store food in secure containers, manage rubbish properly, reduce clutter in storage areas, and address conditions that provide shelter. If rodent activity continues, a more thorough assessment may be necessary.
