Seasonal Activity Patterns

Core PrincipleIntermediate Level

Recognizing pest phenology - seasonal emergence, breeding, and migration patterns that affect when pests are most active and treatable.

Detailed Overview

Most pests have seasonal activity cycles PCOs must understand. Spring: termite swarms (March-May), carpenter ant foraging increases, cluster flies emerge from overwintering, mosquito populations build. Summer: peak activity for most outdoor pests, ant colonies reach maximum size, wasp/hornet nests grow, mosquitoes peak, flea populations explode outdoors. Fall: rodents seek indoor harborage as temperatures drop, Asian lady beetles and boxelder bugs invade for overwintering, last termite swarms. Winter: indoor pest activity continues (German roaches, rodents in heated spaces), outdoor pests dormant or dead, cluster flies and lady beetles overwintering in walls. Timing treatments: Preventative termite treatments before spring swarms. Carpenter ant treatments in spring when workers foraging (easier to find colonies). Grub preventatives late summer when eggs hatching. Flea treatments begin spring continuing through fall. Mosquito programs start when temperatures reach 50°F consistently. Wasp preventative treatments early spring before nest establishment. Rodent exclusion work before fall migration indoors. Overwintering pest exclusion in late summer before aggregation. Seasonal patterns affect call volume - anticipate and staff accordingly.

When to Use

Plan treatment timing based on seasonal pest activity. Offer seasonal programs (mosquito season, spring termite inspection). Anticipate call volume increases. Educate customers on seasonal patterns.
