LOCAL SEASONAL GUIDE

Eastern Ontario Seasonal Pest Calendar

Pest pressure changes with temperature, moisture, food and building use. This calendar helps property owners anticipate common activity without assuming every sighting requires treatment.

01

Winter: indoor rodents and hidden insects

Cold conditions concentrate attention on heated structures. Mouse evidence, stored-product pests, cockroaches and occasional overwintering flies may be noticed indoors.

  • Monitor kitchens, storage and utility rooms
  • Check door seals and exterior gaps
  • Document fresh evidence before cleaning
02

Spring: ants and overwintering pests

Warm days activate ants, cluster flies and insects that sheltered in wall voids or attics. Moisture and spring repairs can reveal hidden access points.

  • Inspect rooflines, windows and foundations
  • Correct damp wood and drainage issues
  • Identify ants before choosing treatment
03

Summer and fall: wasps, flies and rodent entry

Summer supports outdoor insects and nest growth. As nights cool, rodents and overwintering insects begin testing buildings for shelter.

  • Watch steady wasp flight paths
  • Manage waste and standing water
  • Complete exclusion before late-fall pressure peaks

Use evidence, not guesswork.

Photos, specimens, dates and exact locations help distinguish a one-time sighting from an active structural pest problem. Product use must follow the Canadian label and should match the identified pest and site.
