Common commercial pests in St. Louis
Based on regional pest pressure patterns and climate conditions.
German Cockroaches
Extreme temperature swings — from subzero winters to 90°F+ summers — make German cockroaches a year-round indoor pest. Midwest populations concentrate entirely within heated structures during 5-6 months of cold weather, creating dense persistent infestations. Humid summers then accelerate breeding cycles.
Most affected: Restaurants, Grocery, Food Processing, Hospitality
Rodents
When temperatures plunge below freezing, mice and rats migrate en masse into commercial buildings. The region's major river corridors and extensive agricultural land sustain large rodent populations that push into urban metros each fall. Norway rats dominate sewer systems in older cities.
Most affected: Warehousing, Restaurants, Manufacturing, Healthcare
Stored Product Pests
The Midwest's agricultural heartland proximity means stored product pests have massive source populations nearby. Warm humid summers accelerate insect development in stored goods, while heated winter warehouses provide continuous breeding conditions. Pests hitchhike in via regional supplier shipments.
Most affected: Food Processing, Warehousing, Grocery, Bakeries
Bed Bugs
Midwest metros consistently rank among the top US cities for bed bug infestations. Older commercial building stock provides ideal harborage, and major hub airports ensure constant reintroduction. Harsh winters have no effect — heated buildings maintain ideal reproduction temperatures year-round.
Most affected: Hospitality, Senior Living, Education, Office Buildings
Ants
Freeze-thaw cycles crack foundations and parking lots, giving pavement ants entry points each spring. Odorous house ants form massive multi-queen supercolonies that infiltrate buildings during spring rains. Carpenter ants target moisture-damaged wood common in buildings stressed by ice dams and humid summers.
Most affected: Restaurants, Healthcare, Office Buildings, Retail
Termites
Eastern subterranean termites are active across the southern and central Midwest. Clay-rich soils retain moisture termites need, and freeze-thaw cycles create foundation cracks for entry. Termites remain active year-round beneath the frost line and inside heated structures.
Most affected: All commercial properties
