Rat and mouse control in the South Bay

What rodents look like

The two most common South Bay rodents are roof rats — slender, dark, excellent climbers around 6–8 inches (plus tail) that nest in attics, garages, and vegetation — and house mice, small and gray-brown at about 2–3 inches. Norway rats are stockier and stay lower, near crawl spaces and drains.

Signs of an infestation

• ✔Droppings along walls, in cabinets, or in the garage and attic
• ✔Gnaw marks on wires, food packaging, or wood
• ✔Scratching or scurrying sounds in walls or ceilings at night
• ✔Grease-marked runways or nests of shredded material

How rodents are treated

Rodent control is more than traps — it's about keeping them out for good. A licensed provider inspects for entry points (seal openings larger than about 1/4 inch; young rats can get under a door with a 1/2-inch gap), sets a trapping program to knock down the active population, then seals and excludes those entry points with rodent-proof materials. Where needed, the provider cleans and sanitizes contaminated areas. Trapping without exclusion just invites the next rodent in. A fall walk-around of those gaps is in the fall rodent-proofing checklist.

What does it cost?

Typical LA-area ranges:

• ✔Trapping: $150–$400
• ✔Trapping and sealing: $650–$1,500
• ✔Full exclusion: $1,500–$4,500+

Your matched provider inspects and quotes the job before any work begins. Price depends on property size, severity, and treatment method. Market range as of September 2026, based on published Los Angeles pricing guides.

Rodent control FAQs

How do you stop rats from coming back?

By sealing entry points, not just trapping. After reducing the active population, a provider excludes gaps around rooflines, vents, pipes, and the foundation with rodent-proof materials, because trapping alone leaves the openings that let the next rodent in.

Do you clean up after the rodents are gone?

Yes. A provider can remove droppings and nesting material and sanitize affected areas such as attics and garages. This step matters for both hygiene and to remove the scent trails that attract new rodents.
