Spring Pest Alert
Spring in Metro Vancouver means carpenter ant swarms, pavement ant emergence, raccoon kits in attics, and the first wasp queens establishing colonies. Early-season intervention prevents summer escalation.
Spring is the single most important pest-management window in Metro Vancouver. Most of the year's preventable problems start between March and May — carpenter ant colonies produce swarmers, raccoon females give birth in attics, wasp queens scout for nesting sites, and rodent pressure that survived the winter comes out of hiding. Homeowners who schedule a spring inspection in early April eliminate roughly 80% of the seasonal escalation they'd otherwise face by August.

Spring in Metro Vancouver means carpenter ant swarms, pavement ant emergence, raccoon kits in attics, and the first wasp queens establishing colonies. Early-season intervention prevents summer escalation.
Peak wasp and hornet season. Peak bed bug travel pressure. German cockroaches spike in commercial kitchens. Wildlife kits emerge. This is when Metro Vancouver's pest population is maximally active and most visible.
Rodent season opens. Wildlife seeks winter shelter. The BC legal bat exclusion window (August 16 – October 31) closes. Cluster flies arrive in older homes. Fall is the single-highest-leverage exclusion season.
Rodents are established indoors. Attic wildlife is dormant but present. Indoor pest pressure (silverfish, spiders, German cockroaches in commercial) increases. Winter is the best season for diagnostic inspections.
