Pest Information for Commerce, East Los Angeles

Commerce is a small city dominated by industrial parks, warehouses, and the Commerce Center, with residential pockets like the Bandini area. The industrial infrastructure, including rail yards and trucking hubs, creates unique pest pressures. Large warehouses provide harborage for rodents, particularly Norway rats, which thrive on spilled grain and food debris. The constant movement of goods also facilitates the spread of pests like German cockroaches and stored product pests. The Bandini neighborhood, near the Los Angeles River and the 710 freeway, features older homes (built in the 1940s-50s) with wood foundations that are susceptible to subterranean termites. The river corridor and adjacent green spaces support populations of roof rats and opossums, which can enter attics and crawl spaces. Seasonal rains increase termite activity in spring, while summer heat drives ants and cockroaches indoors. Argentine ants are ubiquitous in Commerce, forming supercolonies that exploit cracks in concrete slabs and building foundations. The abundance of food sources from industrial and commercial facilities sustains large colonies. Homeowners should focus on sanitation and sealing entry points, especially before the rainy season.
