Mice in Ontario: How to Identify Signs and Prevent Entry

House mice can enter through small gaps around foundations, doors, pipes, vents, and garage openings. Droppings, gnaw marks, nesting material, and scratching sounds may indicate activity in kitchens, basements, attics, or wall voids. Mosquito Man inspects likely travel routes and entry points, then recommends targeted control, monitoring, and exclusion steps suited to the property. Read about other pests in our pest library.

what we offer

Our Rat Control Packages

Rat Control

Our rat control package includes 4 visits over 12 months to eliminate existing infestations and help prevent future rat activity. During the initial visit, our technicians strategically place bait stations in areas where rat activity has been detected. After 2 weeks, we return to assess the infestation, seal potential entry points, and refill the bait stations. Follow-up visits are scheduled every 3 months to monitor rat activity, replenish bait, and ensure continued protection for your property.
