Insects and rodent infestations

Rodent infestations can cause disease and costly damage to food.

Our public health inspectors are involved in responding to inquiries and investigating complaints related to infestations.

Infestations in homes may include:

There are various steps you can take to prevent pests from entering your home.

keep outside garbage areas clean
garbage must be stored in spill-proof containers with tight-fitting lids
keep doors and windows closed unless they are screened and ensure all entrances have weather stripping to prevent pest access
check the perimeter for potential entry points
seal outside openings where rodents can enter with coarse steel wool
use sheet metal around pipes and electrical conduits

To limit infestations of smaller pests, block, seal or caulk cracks and crevices around foundations and access points to wall cavities.

store food in tightly sealed plastic or glass containers
store all food at least 15 cm (6 inches) off the floor on shelves or racks for easy cleaning
remove any and all available food and water sources
repair water leaks and clean spills immediately
wrap or insulate pipes that have excessive amounts of condensation
look for sealable access points around baseboards, air vents, sinks and other areas where pipes, plumbing and electrical wires enter your home
