As the temperatures rise and nature awakens in May, so does rodent activity across the Greater Toronto Area (GTA). With the shift from colder months to spring warmth, rodents such as mice and rats become significantly more active, searching for food, nesting materials, and safe indoor environments to breed.
This seasonal change creates the perfect storm for infestations. Rodents multiply rapidly, and the increase in outdoor food sources can drive them indoors when competition grows. Homes, especially those with unsealed entry points or cluttered storage areas, become easy targets. That’s where Pestong Pest Control steps in. With a proven track record and deep local experience, Pestong offers targeted rodent control solutions built for the unique challenges of springtime in Toronto. Whether you’ve noticed early signs of rodent presence or simply want to prevent an infestation before it starts, Pestong is your trusted partner in keeping your home pest-free this season.
Warning Signs: How to Know Rodents Are in Your Home
Rodents are stealthy, but they always leave clues. If you suspect unwanted guests have made their way into your home this spring, keep an eye (and ear) out for the following common signs:
Droppings and Urine Trails
One of the earliest indicators of a rodent problem is the presence of small, dark droppings, typically found near food storage areas, under sinks, or along baseboards. In severe infestations, you might also notice faint urine trails that emit a strong, musky odour.
Chewed Materials

Rodents constantly gnaw to keep their teeth from overgrowing. Look for shredded food packaging, chewed wires, furniture corners, or gnawed plastic containers. These bite marks not only signal rodent activity but also pose fire hazards and risks of food contamination.
Scratching or Gnawing Sounds
If you hear scratching, scurrying, or gnawing—especially during the night when rodents are most active—it’s a strong sign that they’re moving behind walls, in attics, or beneath floorboards.
Nesting Materials in Hidden Spots

Rodents build nests from shredded paper, insulation, fabric, or dried plant matter. These nests are often tucked away in warm, dark corners, like behind appliances, inside cabinets, or within wall cavities.
Spotting even one of these warning signs should prompt immediate action. The sooner you address rodent activity, the easier it will be to prevent a full-blown infestation, especially during the active spring season.
Top Entry Points Rodents Use in Spring
Rodents are expert infiltrators. In spring, they’re especially motivated to find warm, food-secure shelter, making your home a prime target. Even the smallest gaps can become an open invitation for mice and rats. Understanding where they enter is key to effective prevention.
Gaps in Door Frames and Windows

Tiny spaces under doors or around poorly sealed windows can easily allow rodents to squeeze through. Weather stripping that’s worn out or damaged offers no real barrier, and rodents will exploit even quarter-inch openings.
Vents and Pipe Openings
Dryer vents, utility pipe holes, and HVAC system outlets are frequent access points. These areas often go unnoticed during routine inspections, making them one of the most common entryways for spring rodent invasions.
Cracks in Walls and Foundation
Rodents are relentless in exploiting structural weaknesses. Foundation cracks, deteriorating mortar between bricks, or even expansion gaps in exterior walls provide quick and easy routes indoors.

Garage or Basement Entryways
Garages and basements are often the least insulated parts of a home. Open doors, poorly sealed thresholds, or gaps around garage panels provide rodents with a direct path to shelter, especially when clutter offers easy hiding spots.
To protect your home this spring, a thorough inspection of these vulnerable points is essential. Sealing them before rodents find their way in can save you from larger issues down the road.
Practical Prevention Tips for May
May is the perfect time to rodent-proof your home before infestations take hold. With warmer weather and increased activity, early action can keep your living space protected throughout the season. These simple but effective prevention tips can make all the difference:
Seal All Small Holes and Cracks
Inspect your home’s foundation, walls, doors, and windows for tiny gaps. Rodents can squeeze through holes as small as a dime. Use steel wool and caulk to fill in cracks—this combination is durable and difficult for rodents to chew through.
Keep Garbage Bins Sealed and Away from the House
Outdoor trash is a major food source for rodents. Always use tightly sealed lids and place bins several feet away from exterior walls to prevent attracting pests near entry points.
Store Food in Airtight Containers

Whether it’s pantry staples or pet food, keep all edibles stored in plastic, metal, or glass containers with tight-fitting lids. Cardboard packaging can be easily chewed through and offers no protection.
Declutter Garages, Sheds, and Basements
Rodents love to hide in undisturbed, cluttered spaces. Regularly organize and clean storage areas to eliminate nesting opportunities. Use shelves to keep items off the floor and reduce hiding spots.
Trim Vegetation Near the Foundation

Overgrown bushes, shrubs, and tree branches provide shelter and a direct path to your home’s walls and roof. Keep landscaping well-maintained and trimmed back to reduce access points and conceal potential hiding spots.
Implementing these tips in early spring can create a strong barrier against rodents and reduce the need for reactive pest control later on.
Why May Is the Best Time for Professional Rodent Control
Timing is everything when it comes to rodent pest control, and May offers a strategic window of opportunity. As rodent activity spikes with the change in weather, taking professional action now can prevent larger problems later.
Rodents Breed Quickly

A single pair of mice can produce dozens of offspring in just a few months. By addressing the issue early in spring, you can stop small problems from snowballing into full-blown infestations during the summer.
Perfect Season for Long-Lasting Protection
May’s mild temperatures make it an ideal time for applying preventative treatments. Unlike the extremes of winter or summer, spring conditions allow pest control products, such as repellents, exclusion sealants, and bait stations, to work more effectively and last longer.
