Scratching in the walls at night means mice are already inside. They chew wires behind your kitchen and bedroom. They leave droppings near food storage and countertops. Left alone, one mouse family becomes twenty within eight weeks. Markham’s older Unionville homes and newer Cornell townhouses both give mice easy entry.
Pestiseed Pest Control has treated mice problems across Markham since 2019. Our technicians are WHMIS and TDG trained for safe chemical handling. We use Health Canada registered bait stations, sealed and locked. Every inspection covers your attic, basement, and crawl spaces. Most Markham homes see mice activity stop within 48 hours of treatment.
Fresh droppings look dark and slightly soft. Old droppings turn grey and crumble apart. Urine smell grows stronger in closets, basements, and garages. In Unionville’s older homes, mice enter through settled foundation gaps. In Cornell’s townhouse rows, they travel between units through shared wall voids.
Our technicians trace every entry point back to its source. Grease marks along baseboards show regular mouse travel routes. Chewed wires behind walls create a real fire risk. Torn paper and fabric in attics confirm active nesting. One untreated unit in a Markham townhouse row can re-infest the whole block.

Droppings near kitchen cupboards are the clearest warning sign. Fresh droppings look dark and soft. Old droppings turn grey and dry. Pets often sense mice before you notice any signs. Cats and dogs react to walls, vents, or cabinets.
New holes along your foundation mean mice found a way in. They widen gaps the size of a dime. Urine odor grows stronger in closets and garages. If you notice two or more signs, call today. Waiting lets a few mice become a full infestation.
Every Markham mice job starts with a free inspection no cost, no obligation. A trained technician checks your attic, basement and crawl spaces first. He photographs every droppings trail, grease mark and entry point. You see the exact evidence he finds, room by room. A written estimate follows before any work begins, priced by property size and infestation severity.
Treatment combines sealed bait stations, entry point sealing, and pet safe placement in one visit. Bait stations use Health Canada registered products, locked and tamper resistant.

Single family homes, townhouses and condos each get a full inspection and treatment plan. Restaurants and commercial kitchens need mice free records to pass health inspections.

Industrial sites and loading docks face this risk across larger, harder to seal spaces. Schools, daycares and healthcare facilities require mice free certification for safety compliance. Multi-unit buildings spread mice fastest between shared walls and utility lines. No Markham property is too large or too small for full treatment.
