How Much Does Pest Control Cost in San Diego, CA? (2026) Prices for Ants, Termites, Rodents, and More

A one-time pest control visit in San Diego, CA runs $150 to $300 this year for a general treatment covering ants, spiders, and common crawling insects, and a quarterly service plan runs $45 to $75 per month. Termite work is a different scale: a spot treatment starts around $400, a full tent fumigation on a 2,000 square foot house runs $2,500 to $5,000, and a subterranean termite treatment with a soil barrier runs $1,200 to $3,500.

San Diego's mild climate means pests never take a season off, and the county's mix of coastal stucco homes, canyon lots, and older wood-frame houses in North Park and La Mesa creates a steady market for every kind of pest work. This guide breaks down what each service costs, what drives the price up, and how to tell whether a quote is fair.

General Pest Control Pricing

Argentine ants are the most common call in San Diego County, and they are the reason quarterly service exists here. A one-time ant treatment on an average home runs $150 to $275 and includes a perimeter spray, interior bait placement, and a follow-up if the colony returns within 30 days. Ants come back, especially after the first rain in the fall and during the summer heat, which is why most homeowners in Chula Vista, Escondido, and Santee end up on a plan.

Quarterly service covers ants, spiders, earwigs, silverfish, and other crawling insects, with the technician treating the exterior perimeter every three months and coming inside on request. Plans run $45 to $75 per month in most of the county, billed quarterly at $135 to $225 per visit. Bimonthly plans, which some companies push for homes near canyons or with heavy ant pressure, run $60 to $95 per month.

The initial visit on a plan is usually priced higher, at $150 to $250, because the first treatment is more thorough. Some companies waive it with a one-year commitment. Ask before signing.

Cockroach treatment, mostly for German roaches in kitchens and American roaches coming up from drains, runs $150 to $400 depending on severity. A heavy German roach infestation in a multi-unit building can require several visits and runs $500 or more.

Termites: The Big-Ticket Item in San Diego

Drywood termites are endemic across coastal San Diego, and subterranean termites are common inland. Nearly every home sale in the county involves a termite inspection, and the report often finds something. Inspection alone runs $75 to $150, and many companies offer it free if they get the treatment work.

Localized drywood treatment, where the technician drills and injects a small infested area, runs $400 to $1,200 depending on how many spots are found. It works when the infestation is confined and accessible, and it is the standard first option on a home in Clairemont or Point Loma with one or two active galleries in the eaves or a window frame.

Whole-structure fumigation, the tent treatment San Diegans see on streets every week, is the only method that reaches every drywood colony in a house. Pricing is by cubic footage, and a typical 2,000 square foot single-story runs $2,500 to $4,000, while a two-story house or one with a large attached garage runs $4,000 to $6,000.

Homes in Rancho Santa Fe and Del Mar with 5,000 square feet or more can pass $10,000. The price includes the tent, the gas, the clearance testing, and a warranty of one to three years.

Subterranean termite treatment involves trenching and treating the soil around the foundation with a non-repellent termiticide, or installing a bait station system. A soil treatment runs $1,200 to $3,500 for an average home, and a bait system runs $1,500 to $3,000 to install plus $300 to $500 per year to monitor. Inland communities like El Cajon, Poway, and Ramona see more subterranean activity than the coast.

Heat Treatment as a Fumigation Alternative

Some San Diego companies offer whole-structure or localized heat treatment as a no-chemical alternative to tenting. Localized heat runs $800 to $2,000, and whole-house heat runs about the same as fumigation. It avoids the two-night hotel stay and the bagging of food, though it does not carry the same warranty in most cases.

Escrow and Repair Costs

A termite report in escrow often includes a Section 1 finding that must be cleared before closing. Treatment plus wood repair on a typical sale runs $1,500 to $5,000, and the seller usually pays. Fascia board, eave, and window trim repair after termite damage runs $50 to $150 per linear foot depending on the finish.

Rodents, Bed Bugs, and Wildlife

Roof rats are a year-round problem across San Diego, and they get worse in the fall when the weather cools. A rodent job involves inspection, trapping, and exclusion, which means sealing the entry points, and trapping alone runs $200 to $400 for an initial visit and a couple of follow-ups. Exclusion work, sealing gaps in the roofline, vents, and garage, runs $500 to $2,000 depending on how much access the house has.

Attic cleanup after a rat infestation is a separate charge. Removing contaminated insulation, sanitizing, and reinsulating a 1,500 square foot attic runs $2,000 to $5,000. It is worth getting a second opinion before agreeing to a full attic replacement, since some companies push it when spot cleanup would do.

Bed bug treatment runs $300 to $600 per room for chemical treatment and $1,200 to $2,500 for whole-home heat treatment. Hotels and vacation rentals along Mission Beach and Pacific Beach are the most frequent commercial callers, and residential infestations often trace back to travel.

Gophers and ground squirrels are a constant issue on canyon lots in Rancho Bernardo, Scripps Ranch, and the eastern suburbs. Gopher service runs $75 to $150 per visit or $40 to $60 per month on a plan. Skunks, raccoons, and opossums require a licensed wildlife trapper, and removal runs $250 to $500 per animal plus exclusion.

Mosquitoes and Flies

Mosquito service has grown in San Diego as invasive Aedes mosquitoes have spread across the county. A monthly yard treatment during the warm months runs $75 to $150 per visit, and a season of service from April through October runs $500 to $900.

What Drives the Price Up or Down

Home size and lot size set the base. A 1,200 square foot condo in Mira Mesa costs less to treat than a 3,000 square foot house on a half-acre in Alpine because the perimeter is shorter and there is less to inspect. Canyon lots and homes backing onto open space pay more because pest pressure is higher and the technician spends more time.

Access matters. Crawlspaces, tight attics, and homes with heavy landscaping against the foundation take longer to inspect and treat. Older homes in Golden Hill, South Park, and Kensington with raised foundations are more work than a slab-on-grade house in Otay Ranch.

Severity is the other lever. A single ant trail is a standard visit, while a wall void full of Argentine ants after a heat wave is two visits and a bait program. Companies price by what they find, and a good one explains the difference.

Contracts change the per-visit price, since annual plans cost less per visit than one-time calls and usually include free re-treatments between visits. The catch is the cancellation term, which at some companies runs a full year with a fee to exit early. Read that part of the agreement before signing.

Choosing a Company in San Diego

California requires pest control companies to be licensed by the Structural Pest Control Board, and every technician must hold a license or be registered as an applicator working under one. The board's website lets you check a company's license and any disciplinary history. Fumigation requires a separate Branch 1 license, so a company that subcontracts the tent work should tell you who is doing it.

Get three quotes for anything over a few hundred dollars, and ask each company to put the inspection findings in writing. On termite work, ask for the inspection diagram showing where activity was found, and compare the treatment method and the warranty length, not just the price. Licensed companies across the county are listed in our directory of San Diego pest control services.

Ask what products are used and whether a reduced-risk or organic option is available for households with children, pets, or a vegetable garden. Most San Diego companies now offer one, usually for $10 to $20 more per visit.

How much does termite tenting cost in San Diego?

Whole-structure fumigation on a 2,000 square foot single-story runs $2,500 to $4,000 this year, and a two-story house runs $4,000 to $6,000. Large homes in the coastal north county can pass $10,000. Most tenting comes with a one to three year warranty.

Is pest control worth it for Argentine ants in San Diego?

For most homes, yes. Argentine ant colonies in the county are enormous and interconnected, and a single treatment rarely holds through the summer heat and the first fall rain. A quarterly plan with bait and perimeter treatment is the approach that keeps them out.

How much does rodent removal cost in San Diego?

Trapping runs $200 to $400 for the initial visit and follow-ups, and exclusion work to seal entry points runs $500 to $2,000 depending on the house. Attic cleanup and reinsulation, if needed, adds $2,000 to $5,000.

Do I need to leave my house for termite treatment?

For fumigation, yes, for two nights while the tent is up and the gas clears, with food and medications bagged or removed. Localized drywood treatment, heat treatment, and subterranean soil treatment do not require you to leave.
