A mouse can squeeze through a gap the width of a pencil, which is why house mice keep finding their way into attics in Port Coquitlam and wall voids in Maple Ridge no matter how many traps go down. Norway rats burrow near foundations and crawl spaces, often in yards backing onto green space or water. Roof rats climb — nesting in rooflines and trees around North Vancouver properties long before anyone hears scratching in the ceiling.

Setting traps without finding the entry point is a losing pattern: you catch one rodent while two more come in behind it through the same gap. Chewed wiring, torn insulation, and droppings near stored food are usually the first real evidence, by which point a colony — not a lone mouse — is already established.

We start with a full exclusion inspection to map every entry point on the property, not just the obvious ones, then combine sealing with targeted trapping and baiting to clear the population that’s already inside. Closing the door matters as much as clearing the room — otherwise the next family of mice just moves in behind the last one.
