As winter settles across Coquitlam and nearby communities such as Pitt Meadows, many families and business owners are discovering increasing roof rat activity. These rodents are more than an annoyance—they can lead to attic infestations, health risks, and significant property damage. Understanding why roof rats become problematic during colder months is crucial. Their ability to exploit human habitation amplifies when freezing weather sets in, leading to larger indoor populations and challenges for property owners. 

Today, we will explain why these invaders target attics, how to recognize the warning signs of an infestation, practical winter pest control tips, and how Skedaddle’s humane solutions can protect your property for the long haul.

Why Roof Rats Become a Growing Winter Problem

Roof rats are remarkably adaptable creatures, using their keen climbing skills to access warm, hidden spaces as temperatures drop. In winter, outdoor food sources dwindle, and surviving the cold becomes their priority. Human environments—especially attics and upper floors—offer warmth, safety from predators, and abundant food supplies.

Urban areas like Coquitlam and Pitt Meadows inadvertently create ideal conditions for roof rats to thrive during winter. Some reasons these rodents flock indoors include:

• Attics provide consistent warmth and insulation against cold temperatures.
• Homes offer easy access to food via pantries, trash bins, and pet dishes.
• Roof rats can squeeze through small openings, climbing walls, trees, and utility lines to reach rooftops.
• Older homes or buildings may have gaps, aging vents, or roofline entry points.
• Dense neighbourhoods allow rapid movement between properties.

When these rodents settle in, their populations can grow rapidly—two rats can become over a thousand in just one year. By exploiting our homes for shelter and sustenance, roof rats not only survive but multiply and spread throughout a neighbourhood. This insight emphasizes why winter problems can accelerate if action isn’t taken promptly.

As we continue, let’s break down how these rodents make themselves at home in human environments.

How Roof Rats Exploit Human Habitation in Winter

Roof rats don’t let winter’s chill slow them down. Instead, they are motivated to seek shelter and forage indoors. The transition from yards and fields to attics and upper floors commonly starts in late fall but peaks during the coldest months.

Key ways roof rats take advantage of our properties include:

• Entering through gaps around roofs, vents, chimneys, or loose siding.
• Chewing through weakened building materials, wood, and even light metal flashing.
• Using trees or shrubs close to buildings as bridges to rooflines.
• Nibbling into attic insulation for nesting material and warmth.
• Following plumbing lines and cables that create hidden passageways from foundation to attic.

This behaviour is especially evident in urban sprawl areas, where properties are close together, providing rodents with more ways to move indoors and establish colonies.

Once inside, they avoid high-traffic or noisy areas and prefer spaces where they are less likely to be disturbed. Attics, behind walls, and unused rooms become prime real estate. As populations grow, the infestation can spread quickly if not controlled. 

Typical Signs of an Attic Rodent Infestation

Roof rats often reveal their presence through subtle—and sometimes not-so-subtle—clues. Because they are mostly nocturnal and prefer secrecy, homeowners often miss early warning signs.

During the winter, it’s important to stay vigilant for signs of rodent activity indoors. Key indicators include dark, capsule-shaped droppings near insulation, storage areas, or food sources; piles of shredded insulation, fabric, or paper used for nesting; and fresh gnaw marks on wood beams, wires, or stored items. Unusual scratching or scurrying sounds, especially at night, may signal active rodents, while musky or ammonia-like odours can indicate rat urine. Additional signs include greasy rub marks or oily stains along beams and joists, as well as footprints or tail marks in dusty, undisturbed areas.

If multiple signs are present, it likely means a larger population has already established itself. Early recognition is critical, as unchecked infestations entail major risks to both property and health. To prevent these threats, business owners and homeowners alike need effective winter pest control tips, especially during the peak season for rodent activity.
