Spring: The Awakening

As temperatures rise in spring, dormant pests become active. This season sees a surge in insect activity, particularly ants, termites, and spiders. The increase in moisture from melting snow provides an ideal environment for these pests to thrive.

Homeowners should be vigilant during this time, as pests seek food and shelter. Regular inspections and preventive measures, like sealing entry points and reducing moisture, can help mitigate infestations.

Summer: Peak Activity

Summer in Ottawa brings warmth and humidity, creating perfect conditions for pests such as mosquitoes, ticks, and wasps. These pests are not only a nuisance but can also pose health risks.

Fall: Preparing for Winter

As temperatures drop in fall, pests begin seeking warmth indoors. Rodents, such as mice and rats, are common invaders during this time. They enter homes in search of food and shelter, often causing damage in the process.

To prevent rodent infestations, seal cracks and openings, store food properly, and remove clutter. Regular monitoring and maintenance are key to keeping homes pest-free.

Winter: A Time of Dormancy

Winter in Ottawa is characterized by cold temperatures and snow, leading to a decline in outdoor pest activity. However, some pests, like cockroaches and rodents, continue to thrive indoors.

Homeowners should focus on indoor pest control during winter, ensuring that all potential entry points are sealed and that indoor environments are clean and dry.

Year-Round Prevention Tips

  1. Regular inspections and maintenance.
  2. Sealing entry points and reducing moisture.
