Why Rats Are Invading Fraser Valley Homes This Winter

As winter temperatures settle across the Fraser Valley, homeowners in Chilliwack, Abbotsford, Langley, and Mission are reporting a sharp increase in rat activity. Scratching noises in walls, droppings in garages, and damage to stored food are some of the most common complaints this time of year.

While many people associate pest problems with summer, winter is actually the most active season for rodents entering homes. Cold weather forces rats and mice to seek shelter indoors, and once inside, they can reproduce rapidly and cause extensive property damage.

Why Rats Enter Homes in Winter

Rats do not hibernate. When temperatures drop, outdoor food sources disappear and survival becomes difficult. To stay alive, rats actively search for:

  • Warm shelter
  • Consistent food sources
  • Safe nesting areas

Homes provide ideal conditions, making residential properties prime targets during winter months.

Common Signs of a Rat Infestation

Homeowners should watch for the following warning signs:

  • Rat droppings in garages, basements, or crawl spaces
  • Scratching and movement sounds inside walls and ceilings
  • Chewed food packaging and pantry items
  • Torn insulation and nesting material
  • Gnaw marks on wiring and wood
  • Grease marks along walls and baseboards

Early detection is critical to prevent rapid population growth.

Where Rats Are Entering Fraser Valley Homes

Common entry points include:

  • Gaps around utility and AC lines
  • Openings behind siding and trim
  • Garage door gaps and corners
  • Roofline gaps and soffits
  • Construction and renovation openings
  • Poorly sealed vents
  • Crawl space access points

Rats are excellent climbers and can enter from ground level or the roofline.

Damage Caused by Rats

Rats can cause serious and costly damage, including:

  • Chewed electrical wiring (fire hazard)
  • Destroyed insulation
  • Structural wood damage
  • Contaminated food and surfaces
  • Spread of disease and bacteria

DIY Rat Control vs Professional Rodent Control

DIY traps and poisons may catch individual rats, but they rarely solve the infestation.

Professional rodent control includes:

  • Full property inspection
  • Entry point sealing
  • Strategic trapping
  • Exterior bait stations
  • One-way exit doors
  • Long-term prevention

How to Prevent Rats This Winter

Homeowners can reduce rodent attraction by:

  • Trimming trees and bushes away from the roofline
  • Sealing exterior gaps
  • Storing food in sealed containers
  • Keeping garbage bins closed
  • Maintaining clean garages and storage areas
