Summer Pest Alert
Peak wasp and hornet season. Peak bed bug travel activity. German cockroaches spike in commercial kitchens. Wildlife kits emerge. This is when Delta + Surrey's pest population is maximally active and most visible.
Summer is when latent spring problems become August emergencies. Wasp colonies that were 20 cells in May become 3,000-worker nests by August. A single bed bug introduction in June is a detectable infestation by late July. Commercial kitchens that were subclinical in May can tip into visible cockroach infestations within six weeks of World Cup 2026 opening. Response times matter more in summer than any other season.

Peak wasp and hornet season. Peak bed bug travel activity. German cockroaches spike in commercial kitchens. Wildlife kits emerge. This is when Delta + Surrey's pest population is maximally active and most visible.
Spring in Delta + Surrey means carpenter ant swarms, pavement ant emergence, raccoon kits in attics, and the first wasp queens establishing colonies. Early-season intervention prevents summer escalation.
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 activity (silverfish, spiders, German cockroaches in commercial) increases. Winter is the best season for diagnostic inspections.
