Professional Rodent Control

Critter Control Canada specializes in rodent removal and control. Rodent removal begins with a thorough inspection to determine how severe the problem is. The more established rodents are, the more involved the removal process will be. After inspecting, our wildlife specialist will build a custom solution to trap, remove, and seal all entry points.

Home Inspection for Rodents

During a rodent inspection, our inspector will thoroughly inspect your attic as well as provide a full exterior home inspection. The most common signs of rodent activity are chewing, droppings, rub marks, nesting material, and small entry points.

The most common areas to find a rodent infestation are in your attic, in the crawlspace, and inside the walls. You’re likely to find evidence of rats and mice in your kitchen as they scavenge for food.

Rodent Removal & Trapping

Based on the inspection, our wildlife specialist creates a strategic trapping plan to remove the rodents found in your home. Types of traps, placement of traps, and bait used in traps determine the effectiveness of rodent trapping.

Our wildlife specialist will ensure to use of the most efficient and safe removal process for your home. Though the standard trapping/removal duration is normally between 5 to 14 days, the trapping process may be longer if the rodents are well-established.
