Professional Mice & Rat Control

Mice & Rat Control Options

We start with identification, because mouse and rat work differs in trap size, placement, and timing. The inspection maps active runways, harbourage, and every accessible entry point, then the treatment plan sets out trapping and, where appropriate, secured exterior bait stations. You get the exclusion list in plain language so you know which repairs matter most, and a follow-up visit confirms whether activity has stopped rather than simply gone quiet.

• Trapping

  Snap and multi-catch traps placed along established runways rather than in the open. Trapping removes rodents where they can be found and disposed of, which is the preferred approach in kitchens, food premises, and homes with children or pets.

• Secured bait stations

  Tamper-resistant, keyed stations used where labels and site conditions allow, normally on the exterior and in service areas. Placement, product choice, and record keeping follow the product label and Ontario pesticide rules.

• Exclusion and proofing

  The part that ends the problem: sealing entry points with materials rodents cannot chew through, such as steel wool packed with sealant, hardware cloth, sheet metal, mortar, and new door sweeps and vent covers.

• Monitoring and follow-up

  Non-toxic monitors and a return visit confirm whether activity has actually stopped. For commercial sites, a monitoring map and service log support audits and health inspections.

How much does rodent control cost?

Tell us your city, property type and where you have noticed activity. We explain the proposed service, price and any follow-up before you book. Your quote depends on:

• Whether the pest is mice or rats, and how long the activity has been going on
• The size of the building and how many floors, units, or rooms show activity
• How accessible the affected voids, attics, and crawl spaces are
• How much exclusion work the building needs and how much of it is at height
• Whether monitoring and documentation are needed for audits or a property manager

What your rodent control inspection covers

• Droppings mapped room by room, so fresh activity can be told apart from an old, finished problem
• Rub marks, runways, and gnaw damage traced to the wall voids and service chases they follow
• The building envelope checked at foundation, utility penetrations, vents, soffits, door sweeps, and garage corners
• Attic and crawl space insulation checked for tunnelling, nesting, and contamination
• Food storage, waste handling, and pet food reviewed as the reason activity is concentrating where it is
• Exterior grounds checked for burrows, harbourage, overhanging branches, and fence-line routes

Signs of mice and rats in your property

Scratching in the ceiling, droppings behind the stove, or a chewed cereal box usually means mice or rats have already found a way in. Rodent control that only removes the animals you can see tends to fail, because the entry route, the food source, and the harbourage are all still there. Pest Patrol GTA inspects for those three things together, treats the active population, and gives you a written picture of the repairs that keep the problem from repeating.

• Dark, rice-grain droppings along walls, inside cupboards, or under the sink
• Scratching, scurrying, or gnawing sounds in ceilings, walls, and soffits, usually after dark
• Gnawed food packaging, chewed wiring insulation, or shredded paper and insulation used for nesting
• Greasy rub marks along baseboards and joists where rodents repeat the same route
• A persistent musky ammonia smell in enclosed cupboards, crawl spaces, or attics
• A pet that suddenly fixates on one wall cavity, appliance gap, or corner

How to help prevent mice and rats from returning

• Store dry food, birdseed, and pet food in sealed metal or rigid plastic containers rather than bags or cardboard.
• Fit door sweeps, repair damaged weatherstripping, and screen dryer vents, weep holes, and soffit gaps with metal mesh.
• Keep waste in closed bins away from the wall, and clear food debris from behind and beneath appliances.
• Cut back branches and vines touching the roof, and keep firewood, compost, and stored materials off the ground and away from the building.
• Check the foundation line each autumn, before cold weather pushes rodents indoors.

How to identify mice and rats

Identification, hiding places and life cycle help determine how to treat mice and rats. These details explain what your technician looks for and why preparation and follow-up can matter.

1. Pup

   Birth to about 3 weeks

   Born blind and hairless in a nest of shredded insulation, paper, or fabric. Nests are the reason activity keeps returning to one wall cavity even after traps catch adults.

2. Juvenile

   About 3 to 6 weeks

   Weaned and exploring. Juvenile mice are small enough to slip through gaps adults avoid and are often the ones first seen in daylight.

3. Breeding adult

   From about 6 weeks

   Mature and reproducing. One female can add dozens of rodents to a building in a single season, which is why waiting to act is expensive.

How to identify

7–9 cm body

Life cycle

Pup → Juvenile → Breeding adult

Peak season in Ontario

In southern Ontario, calls climb sharply from late September as overnight temperatures drop and rodents move from fields, ravines, and gardens into heated buildings

Why it matters

Rodents contaminate far more food than they eat, and their droppings and urine can carry salmonella and other organisms
