Rail lines, pallets and rodents on the move
The City of Commerce has described itself as home to four regional rail yards — UP Commerce, BNSF Hobart, BNSF Commerce/Eastern and BNSF Sheila Mechanical — with goods flowing inland from the ports. We don't have trapping data for those corridors. Still, overgrown track edges, stacked pallets, spilled product and constant deliveries are the conditions in which rats and house mice are likely to thrive, and inbound loads may occasionally carry them in.
For rodent control in Commerce, that likely means the pressure comes from outside the building and doesn't fully stop. A single cleanout won't hold; a business needs barriers at every door and a monitoring system that catches new activity early.

Dock doors, bait stations and audit-ready records
At warehouses and food distributors, we start with the openings: roll-up door bottoms, dock-leveler edges, gaps around dock shelters, and conduit or pipe penetrations through block walls. Worn sweeps and seals get replaced, and openings are closed with steel mesh, metal flashing or sealant backed by mesh. Outside, locked and anchored bait or trap stations line the walls and fence line; inside storage areas, we generally rely on traps and monitoring devices rather than loose bait.
Every station is numbered, mapped and checked on a set schedule, and each visit produces a written report showing activity, actions taken and repairs still needed. Health inspectors and auditors look for that kind of record. The January 2026 county closure of a food-selling truck stop on E Washington Blvd for a vermin infestation is a local reminder of what is at stake for food businesses inspected by LA County Environmental Health.

Rodent-proofing 1950s homes, and the flea link
Because the typical Commerce house dates to 1957, many have original foundation vents, attic and gable openings, and garage doors that no longer meet the slab. Roof rats tend to enter high, along fences, wires and branches; house mice come in low, through gaps beside pipes and under doors. Our exclusion covers both the roofline and the foundation, and trapping continues inside until checks come up empty.
Rodents also matter for disease. LA County Public Health counted a record 220 cases of flea-borne typhus during 2025, spread by fleas that live on rodents, opossums and feral cats. The outbreaks the county named were not in Commerce, but sealing the openings wildlife uses to get under and into homes is one of the prevention steps it recommends.
