Rodent Control

The most common rodents in this area are the Norway rat, roof rat, and house mouse. Each of these rodents have the potential to reproduce rapidly. Rodents are a health concern, so if you have found rodents on your property, address the issue as quickly as possible for your own benefit as well as your neighbours.

Help Control the Rodent Population

HealthlinkBC provides the following advice on how to deal with rats and mice on your property.

1. Eliminate food and water sources:

  • Keep all garbage in pest proof containers with tight fitting lids.
  • Follow good composting practices for rodent control.
    • Do not throw food scraps into backyard compost without covering them.
    • Use lime.
    • Rotate compost.
    • Have a pest proof compost container.
  • Remove fallen fruit and nuts from your yard.
  • Remove pet food right after feeding and do not leave it outside overnight.
  • Clean out waste and food from pet pens and enclosures.
  • Equip bird feeders with trays and clean spilled seeds often.
  • Repair any plumbing leaks to remove a water source.
  • Cover pools and whirlpools when not in use.

2. Eliminate hiding and living places:

  • Keep building perimeters clear of plantings, stored lumber or junk.
  • Trim plants near buildings so that 15 to 20 cm (6 to 8 inches) above ground is clear. Trim branches of trees or shrubs to prevent access to roofs or balconies.
  • Remove unused piles of lumber and old sheds.
  • Do not store old cars or furniture outside.
  • Store lumber and firewood on stands 30 cm to 45 cm (12 to 18 inches) off the ground.

3. Pest proof buildings:

  • Cover crawl spaces, fresh air and attic vents with 6mm (1/4 inch) metal screening or steel mesh.
  • Seal any possible entry points in the building exterior that are greater than 6mm (1/4 inch). Pay close attention to door jams and gaps between the siding and the house foundation. If you have roof rats don’t forget to check for holes in areas of the roof.
  • Repair cracks in cement footings and foundations.
  • Build sheds on concrete slabs.
