Rat infestations can create serious sanitation and property concerns in both residential and commercial settings. In homes, rats may contaminate food storage areas, leave droppings and urine, damage insulation, chew wood and plastic, and gnaw wiring or utility materials. In businesses, rat activity can affect cleanliness, customer confidence, inventory, and daily operations, especially in restaurants, food handling spaces, warehouses, retail settings, and multi-unit properties. Outdoor rat activity around sheds, fences, compost areas, dumpsters, and foundations can also lead to indoor infestations if access points are left open. Because rats are highly adaptable and often stay hidden, recurring signs usually point to a larger underlying problem that needs professional inspection and targeted control.

The most common rats found in Canada are the Norway rat and the roof rat. Norway rats prefer ground-level burrows, crawl spaces, damp areas, and building perimeters, while roof rats are agile climbers more often associated with trees, attics, rafters, roofs, and upper levels of buildings.

Common warning signs include scratching in walls or ceilings at night, droppings, gnaw marks, grease marks along walls, burrows near foundations, damaged food packaging, or repeated activity around garbage and exterior entry points. Correct identification matters because effective rat control depends on where the rats are nesting, how they are getting in, and whether the activity is happening at ground level or higher up in the structure.

If you are seeing rat droppings, hearing scratching at night, noticing burrows near the foundation, or finding signs of chewing or contamination, the best next step is a professional rodent inspection. Rats reproduce quickly, and visible activity often means there is more happening behind walls, under floors, in crawl spaces, attics, garages, or exterior nesting areas. A licensed pest control technician can identify the species, locate entry points, assess nesting and travel routes, and recommend targeted rat treatment and prevention steps to help stop the infestation at the source.
