How Much Does Pest Control Cost in Los Angeles, CA? (2026) Roof Rats, Drywood Termites, and Quarterly Plans

A one-time general pest treatment in Los Angeles, CA runs about $150 to $375 in 2026. Recurring quarterly service lands between $110 and $185 per visit, with a heavier first treatment at $175 to $350 because that visit has to knock down a population that built up across a long warm season.

Nothing here gets a hard freeze, so the pest calendar never resets. That single fact explains why so much of this market is sold as an ongoing agreement instead of a service call. The pests outside your wall in January are the same ones that were there in August.

The bigger difference from most of the country is which pest drives the spending. Roof rats own this city, moving along fence lines, power lines, and the fronds of untrimmed palms into attics across Pasadena, Silver Lake, Mar Vista, and the hillside streets above Glendale. Rodent work and termite work together account for most of the serious money homeowners spend on this.

Roof Rats Are the Local Signature Problem

Roof rats climb, which changes everything about the treatment. They enter through roof lines, vent screens, gaps at the eaves, and the space where a garage door meets the frame, not through a hole at the foundation. A perimeter spray does nothing to them.

Fruit is the reason they thrive here. A backyard citrus tree, an avocado, or an unharvested fig feeds a population year-round, and untrimmed palm skirts and dense bougainvillea give them cover and nesting material. Homes on the canyon edges in the Santa Monica Mountains and along the Verdugos have constant pressure from the open space on one side.

The first symptom people notice is scratching in the ceiling around dusk. By then a pair has usually become a colony, and every week of delay increases the cost of the eventual fix. Rats also chew wiring, which turns a pest problem into an electrical one.

Trapping Ends the Symptom, Exclusion Ends the Problem

A trapping program typically costs $350 to $700 for a series of visits over two to four weeks. That clears the animals currently inside and does nothing to stop the next ones, which is why homeowners who buy trapping alone tend to buy it again the following year.

Exclusion is the work that matters. Sealing roof-to-wall junctions, vent screens, plumbing penetrations, garage door corners, and the gaps around a rooftop condenser commonly runs $600 to $3,000 depending on the size and condition of the house. Older homes with wood shake, open eaves, or a converted attic sit at the top of that range.

Attic Cleanup Is the Cost Nobody Budgets

Once rats have lived in an attic for a season, the insulation is contaminated and the pheromone trails attract the next generation. Removal, sanitizing, and reinsulating an average home runs $1,500 to $5,000, and larger or steeper attics push higher. Insurance rarely covers any of it.

Skipping the cleanup after exclusion is the most common false economy in this category. The odor persists, the contamination stays, and the attic keeps advertising itself to anything that comes along the roofline next. Ask for the cleanup as a line item on the original quote rather than as a surprise later.

What a General Plan Covers and What It Costs

Standard service in this market handles ants, spiders, roaches, silverfish, earwigs, and crickets. Technicians treat interior entry points and cracks, then band the exterior foundation, eaves, and window frames. Quarterly pricing sits at $110 to $185 per visit for a home under 2,500 square feet.

Square footage moves the price in steps rather than smoothly. Most companies price up to 2,000 square feet as a base and add $15 to $40 for each additional 1,000, so a 3,600 square foot house with a long perimeter and a detached garage commonly quotes $170 to $230 per quarter. Bimonthly plans at $90 to $150 per visit exist for properties with steady pressure.

Read the exclusion list before signing anything. Rodents, termites, mosquitoes, bed bugs, bees, and wildlife are quoted separately by nearly every company, and homeowners who assume otherwise find out during an unpleasant phone call. Annual math is the honest comparison: quarterly service works out to roughly $500 to $800 a year.

Argentine Ants Move With the Weather

Argentine ants form enormous interconnected colonies across the basin and surge indoors twice a year for opposite reasons. Summer heat dries their outdoor food and water sources and drives them to kitchens and bathrooms, and the first real rain floods the shallow nests and pushes them inside again. Most general plans here are built around that cycle.

Spraying a visible trail is the wrong move and makes the problem worse by splitting the colony. Non-repellent products and bait allow foragers to carry the material back, which is the difference between a professional treatment and a can from the hardware store. Expect two to three weeks for a heavy interior population to collapse.

German Roaches Are Their Own Project

A German cockroach infestation in a kitchen is not covered by a general plan in any meaningful way. Clearing one takes a series of three to four visits using gel bait and insect growth regulators, and it runs $350 to $700 for a single-family home. Egg cases survive treatment and hatch on their own schedule, which is why one spray never finishes it.

Multi-unit buildings complicate the math. Treating one apartment while the neighboring units go untreated produces a reinfestation within weeks, and reputable companies say so up front. Any operator promising a one-visit fix on German roaches is selling you a return trip at full price.

Drywood Termites and the Tent

Drywood termites live entirely inside the wood with no soil contact, which makes them the dominant termite problem across coastal and Southern California. Older homes with exposed rafter tails, wood trim, and original framing carry the most risk, and the 1920s through 1950s stock across Mid-City, Highland Park, and the older parts of the Valley qualifies. The first evidence is usually small piles of pellets that look like coarse sand.

Whole-structure fumigation runs $2,500 to $8,000 for an average home and climbs from there on larger houses. The tent seals the structure for two to three days and the gas reaches colonies no spot treatment can find. It kills everything active and leaves no residual protection, so reinfestation remains possible afterward.

Fumigation carries costs beyond the quote. You vacate for two to three nights, remove or double-bag food and medication, and arrange for pets and plants, and hillside lots with tight access or overhanging trees add setup labor. Budget for lodging as part of the project rather than treating it as an afterthought.

Local treatment costs less and works when the activity is limited and reachable. Spot treatments with foam or borate injection run $500 to $2,500, and whole-structure heat treatment lands at $1,500 to $4,000 as a fumigation alternative on some homes. Orange oil marketing gets aggressive in this market, so ask exactly which galleries were located and how the company verified the infestation is confined.

Escrow adds its own line. A wood-destroying pest report for a sale runs $95 to $250, and sellers who order one early rather than during escrow keep control of the repair negotiation instead of reacting to a buyer's inspector.

Mosquitoes Became a Real Line Item

The invasive Aedes mosquitoes that spread across the region over the past decade bite during the day and breed in containers holding as little as a bottle cap of water. That behavior broke the old assumptions, because they do not come from a marsh a mile away. They come from the saucer under a patio plant, a clogged gutter, or a bromeliad.

Source reduction is the treatment that works, and it is mostly free. Emptying saucers weekly, flushing gutters, treating fountains, and turning over anything that holds water eliminates more mosquitoes than any spray. Your local vector control district will inspect a property and identify breeding sites at no charge, which is worth a call before hiring anyone.

Professional barrier treatments run $80 to $175 per visit on a monthly schedule, putting a full season at $500 to $1,000. In-line misting systems install at $2,500 to $5,000 plus $300 to $600 a year in refills. Neither one solves a neighbor's untreated pool, which is the limitation nobody mentions in the sales call.

How California Licenses This Trade

The Structural Pest Control Board regulates pest control here, and its licensing splits into three branches that matter to you as a buyer. Branch 1 covers fumigation, Branch 2 covers general pest control, and Branch 3 covers termites and other wood-destroying organisms. A company doing your termite work needs Branch 3, and the company doing your quarterly ant service does not.

Individual credentials sit underneath the company license. The person inspecting your house and writing the report should hold a field representative or operator license in the relevant branch, and both the company and the individual are searchable on the board's site. Two minutes there settles most questions.

Insurance is the check homeowners skip. Ask for a certificate of general liability sent from the agent rather than a copy forwarded by a salesperson, particularly for fumigation or attic work. Then read the agreement for the cancellation fee, the initial term, whether re-service between visits is free, and what the price renews at after the promotional year.

Guarantees vary more than prices do. A strong general plan includes unlimited free re-treatments between scheduled visits, and a strong termite agreement covers both retreatment and repair. Putting three licensed pest control companies near you against the same written scope exposes the thin offer quickly, and our Los Angeles home service pricing guides cover the roofing, attic, and landscaping work that often turns up alongside a rodent job.

Frequently Asked Questions

How much is monthly pest control in Los Angeles?

Very few companies here sell true monthly general service, and those that do charge roughly $45 to $80 a month billed against quarterly or bimonthly visits. Annualized, that matches the $500 to $800 most homeowners pay for quarterly service.

Why do I have rats if my house is clean?

Roof rats come for shelter and fruit rather than for crumbs. A single unharvested citrus tree, an untrimmed palm, and a quarter-inch gap at the eave line are enough, which is why exclusion work at $600 to $3,000 outperforms any amount of interior tidying.

How much does it cost to tent a house for termites?

Whole-structure fumigation typically runs $2,500 to $8,000 for an average home, scaling with cubic footage rather than square footage. Add two to three nights of lodging, since the structure stays sealed and cannot be reoccupied until the clearance reading passes.

Does a regular pest plan cover mosquitoes?

Almost never. Barrier treatments are quoted separately at $80 to $175 per visit, and a call to your vector control district for a free breeding-site inspection often reduces the problem more than the first treatment does.

Who licenses pest control companies in California?

The Structural Pest Control Board, which issues company registrations and individual licenses across three branches covering fumigation, general pest, and termite work. Verify that a company holds the branch matching the work you are buying before you sign anything.
