Licensed pest control in San Diego, CA
San Diego Pest Control & Extermination Services
San Diego pest control is mostly about drywood termites, Argentine ants and roof rats, because the mild coastal climate lets all three work year-round. East County spots like El Cajon and Santee add scorpions and black widows in the heat, while Chula Vista deals with invasive mosquitoes. Fill out our form and we’ll connect you with a licensed San Diego County company for a free quote. Plan on $300 to $550 for a single general visit.

Pest Control Services In San Diego
Coastal fog, dry inland canyons and plenty of postwar tract homes shape what San Diego pros treat.
Termite ControlDrywood termites are the big one here, and Formosan subterranean termites have been confirmed in La Mesa too. Whole-house tenting is common on older coastal homes.
Ant ControlArgentine ants run most San Diego yards. They tend aphids on citrus and roses, then follow irrigation lines straight indoors.
Rodent ControlRoof rats move through the canyons and into attics in Mission Valley and Poway. Sealing roof vents and trimming palms matters as much as traps.
Scorpion ControlScorpions turn up in El Cajon, Santee and Poway, where homes back onto dry brush. For most healthy adults the sting hurts like a bee sting and passes.
Spider ControlBlack widows hide in garages, block walls and outdoor furniture across East County. Brown widows, a newer arrival, are now common in Chula Vista and National City yards too.
Mosquito ControlAedes aegypti, the yellow fever mosquito, has been in San Diego County since 2014. It bites in the daytime and breeds in plant saucers and buckets.How Much Does Pest Control Cost In San Diego?
San Diego homes pay $300 to $550 for a one-time general treatment, which matches Angi’s national figure. Drywood termite work near the coast and canyon-edge lots with heavy rodent pressure push bills higher.
These are Angi’s national ranges, not San Diego quotes. Condo and HOA buildings may already have a pest contract, so check before paying for your own.
| Job | Typical price |
|---|---|
| One-time general treatment | $300 to $550 for ants, spiders or a roach problem |
| Quarterly plan | $100 to $300 per visit, popular inland where scorpions keep showing up |
| Termite spot or bait treatment | $250 to $1,000 for one or two drywood colonies |
| Drywood termite tenting | $1,500 to $8,000 for whole-house fumigation |
| Rodent work | $180 to $600 for trapping and exclusion on canyon-edge homes |
What To Know About Pests In San Diego
Formosan subterranean termites have been confirmed in La Mesa, as reported by 10News and Pest Control Technology magazine. California has very few known Formosan sites, so ask about them during any La Mesa termite inspection.
The yellow fever mosquito (Aedes aegypti) was first found in San Diego County in 2014, with more finds in Chula Vista that same year. The County’s Vector Control Program takes mosquito complaints and gives out free mosquitofish for ponds and unused pools.
When Pests Are Most Active In San Diego
- Spring
- Subterranean termites swarm after spring showers, and Argentine ants get busy as yards warm up.
- Summer
- Inland heat pushes scorpions and black widows toward shaded garages in El Cajon and Santee. Yellow fever mosquitoes ramp up in backyard water.
- Fall
- Drywood termite swarms show up on warm, sunny fall days. Roof rats head for attics once the nights get cooler.
- Winter
- Rainy spells bring ant trails indoors. The cooler months are a smart window for a termite inspection ahead of swarm season.

When You Can Skip The Pro In San Diego
A few ants on the counter or one spider in the garage won’t need a pro. Use bait, clear the clutter and keep firewood off the house wall.
Bring in a licensed company for pellet piles, scorpions indoors more than once, or rats in the attic. Termites near the coast and rats in canyon homes get worse every month you wait.

San Diego Pest Control FAQs
Ask us in the form about anything else at your San Diego home.
Are Formosan termites a problem in San Diego?
They’re rare in California, but confirmed colonies have turned up in La Mesa. They build huge underground colonies and do damage faster than the native subterranean species.
Mud tubes on a foundation or swarms of yellowish-brown termites at dusk are reasons to book an inspection.
Who do I call about mosquitoes in San Diego County?
The County of San Diego Vector Control Program handles mosquito complaints and dead-bird reports. Call or submit a request online.
They also hand out free mosquitofish for ponds, fountains and green pools.
Are scorpions dangerous in East County?
The scorpions around El Cajon, Santee and Poway sting about as hard as a bee for most adults. Small kids, older people and anyone with an allergy should get checked if stung.
Door sweeps, sealed weep holes and moving rock piles and wood away from the house cut down on indoor run-ins.
Does my San Diego HOA cover pest control?
Many condo and townhome HOAs cover common areas, and some handle termite tenting for the whole building. Read your CC&Rs or ask the management company.
Ants and roaches inside your own unit are often your bill.
How long should kids stay off the lawn after a yard treatment?
Keep kids and pets off until the spray dries, which on a sunny San Diego afternoon often takes an hour or two.
Ask the tech for the product label and its re-entry time, since some products carry specific instructions.

Yard-only companies, like mosquito and lawn sprayers, are licensed by the Department of Pesticide Regulation and register with the county agricultural commissioner instead.
