What you may notice
What we do next
A rodent problem can happen even in a well-kept home. The right solution depends on where the animals are and how they are getting inside.
Call us and simply tell us what's happening. We'll listen first, then explain the best next step.
A trap may remove one rodent without explaining how it entered or whether others remain. Effective mouse and rat control begins by identifying the animal, locating active areas and checking the routes that connect those areas to food, water and shelter.
Gestion Parasitaire D'Amour assesses the complete situation before recommending treatment. A problem inside a kitchen wall is not handled the same way as activity in an attic, a foundation burrow or a rat entering near plumbing. The intervention is adapted to what the inspection reveals.
Identify the problem
The signs can overlap, but the animal's size, droppings, travel routes and entry points affect the treatment plan.
Mice can use extremely small gaps and often travel close to walls, cupboards and stored food. Health Canada notes that a mouse can enter through an opening about the size of a dime.
Rats leave larger signs and may travel through foundations, basements, drains or outdoor burrows. Health Canada notes that a rat can enter through an opening about the size of a quarter.
Inspection and exclusion
Rodents do not always enter through an obvious hole at ground level. The inspection may extend from the foundation to the roofline and follow openings around utilities, ventilation and plumbing.
In Montréal, rat activity can also be connected to damaged drains, unused plumbing openings, broken pipes or nearby excavation. If the lasting solution requires plumbing, structural work or another specialized trade, Alexandre can identify the next step and refer or coordinate with the appropriate professional.
A situation-specific response
The order matters. Closing an opening too early can trap an adult or its young inside a wall, pipe or attic. Alexandre determines what may still be inside before deciding when treatment, removal and sealing should occur.
The inspection begins with the signs you noticed, then checks droppings, damage, routes, possible nesting areas and the parts of the building most likely to provide access.
Interior and exterior clues are connected so the intervention addresses how the rodents move through the property, not only the room where one was seen.
The method depends on the animal's location and whether adults or young may remain inside. When appropriate, the response may include a one-way exclusion device or another control method suited to the inspection findings.
When the situation requires it, Alexandre removes accessible dead rodents and cleans or decontaminates affected areas rather than leaving the client to manage the contamination alone.
Openings are addressed according to the situation and only when doing so will not leave rodents trapped inside. Follow-up is used to determine whether activity continues and what should happen next.
Cleanup and safety
Health Canada advises against sweeping or vacuuming dry rodent droppings because this can send contaminated dust into the air. Keep children and pets away from the area and speak with Alexandre before disturbing a heavily affected space.
Cleanup and decontamination are assessed according to the affected material, accessibility and extent of contamination. Dead-rodent removal is also handled when required and accessible.
Estimate and scope
There is no useful one-price answer before the property is assessed. The estimate depends on what animal is present, where it is active, how it entered and which treatment, removal, cleanup or corrective work is required.
The inspection and estimate are free. Alexandre explains the recommended work and confirms the price before starting.
Apartments and rental properties
A tenant who sees mice or rats should notify the landlord promptly. The City of Montréal states that the landlord must arrange for an extermination company and make the necessary corrections to the dwelling.
If you see rats around or inside a building, note the location, time and signs observed, then call Alexandre. A property inspection may also reveal a plumbing or building defect that needs another specialist.
Mouse and rat questions
Dropping size, gnaw marks, noise, tracks and the location of activity provide useful clues, but a clear identification usually requires looking at several signs together. Alexandre inspects the active areas and likely routes before choosing a treatment intended for the animal actually present.
Not necessarily. Sealing too early could trap an adult or young rodents inside a wall, attic or pipe. Alexandre first determines what may remain inside and how the animals are moving, then decides which openings should be addressed and when it is safe to do so.
Do not sweep or vacuum dry droppings. Keep children and pets away, avoid disturbing the area and call for advice. Health Canada recommends dampening contaminated material before cleanup and using appropriate protection. Alexandre can assess whether professional cleaning and decontamination are needed.
The treatment is selected for the specific property and uses only products registered by Health Canada when a product is required. Alexandre explains the precautions for occupants, children and animals before work begins. Always follow those instructions and do not move any installed control device.
The price depends on the animal, the location of activity, access points, contamination and the work required. A kitchen sighting, an attic nest and a plumbing-related rat problem can require different responses. The inspection and estimate are free, and the price is confirmed before work begins.
The inspection looks for signs that connect the rodent activity to plumbing or building access. If a lasting correction requires a plumber, construction work or another specialist, Alexandre explains the issue and helps direct the client to the appropriate next step instead of pretending one treatment will solve it.
