Integrated Pest Management for Mosquitoes

Mosquitoes are more than a backyard nuisance in San Diego — the local Culex mosquito can carry West Nile virus, and the invasive Aedes aegypti has now established itself across the county. This Integrated Pest Management (IPM) plan puts the emphasis where it belongs: eliminating the standing water where mosquitoes breed, then layering in prevention, biological controls, and professional treatment only when needed.

Nearly every mosquito problem traces back to water. Get rid of the breeding sites and you solve most of the problem before a single adult ever takes flight.

Main Disease Risk West Nile virus

Mosquitoes in San Diego

Three species matter locally — and they differ in when they bite and what they can carry.

Southern House MosquitoCulex quinquefasciatus

West Nile vector

The most common local mosquito and the primary carrier of West Nile virus in San Diego. It bites mainly at dusk and after dark.

Appearance
Predominantly brown; pale bands and a blunt-tipped abdomen
Bites
Dusk and nighttime
Carries
West Nile virus
Note
Breeds readily in stagnant, polluted water

Yellow Fever MosquitoAedes aegypti

Invasive · day-biter

An invasive species now established in San Diego County. Small and aggressive, it bites during the day and can transmit dengue, Zika, and chikungunya if those viruses are introduced.

Appearance
Black with white markings; lyre pattern on the thorax
Bites
Daytime, often around the ankles
Carries
Dengue, Zika, chikungunya (if introduced)
Note
Breeds in tiny containers — even a bottle cap of water

Anopheles MosquitoesAnopheles spp.

Rare local risk

Present in the region and a malaria vector worldwide, though malaria is not currently transmitted locally. Recognizable by its angled resting posture.

Appearance
Dark brown to black; spotted wings
Bites
Dusk and nighttime
Carries
Malaria (not locally transmitted)
Note
Rests at a distinct angle to the surface
Common backyard mosquito breeding sites in San Diego, including saucers, buckets, and clogged gutters

It all starts with standing water

A mosquito needs only a bottle cap of water to breed — and your yard is full of hiding spots for it: plant saucers, clogged gutters, forgotten buckets, tarps, and toys. Walking the property once a week and tipping out every bit of standing water is the single most effective thing you can do to control mosquitoes.

The framework

The IPM Approach for Mosquitoes

How GC Termite Control manages mosquitoes — from source reduction to a judicious chemical last resort.

01 Monitoring & Identification

Surveillance shows where mosquitoes are breeding and which species — and which disease risks — are present.

  • Survey the property and use traps to gauge activity levels
  • Identify species, since behavior and disease risk differ between Culex and Aedes
  • Record breeding locations, weather, and any control measures over time
02 Prevention

Source reduction is by far the most effective mosquito control: no standing water means no breeding.

  • Empty and scrub bird baths, plant saucers, buckets, tires, and toys weekly
  • Keep gutters and downspouts clear so water cannot pool
  • Screen or cover rain barrels and water features
  • Repair leaks and drain AC condensate and low spots
03 Cultural Control

Adjusting habits and landscaping reduces both breeding sites and your exposure.

  • Schedule outdoor activity away from dawn and dusk when Culex is most active
  • Use fine screens on windows and doors, and nets where needed
  • Grade landscaping for drainage and use drip irrigation instead of sprinklers
04 Biological Control

Natural predators and targeted biological agents suppress larvae without broad spraying.

  • Stock ornamental ponds with mosquitofish (Gambusia), which eat larvae
  • Encourage dragonflies, damselflies, and bats that feed on mosquitoes
  • Apply Bti (Bacillus thuringiensis israelensis) to water that cannot be drained — it targets larvae and spares other wildlife
05 Mechanical & Physical Control

Traps and barriers cut down adult mosquitoes and keep them out of living spaces.

  • Use CO2, light, or heat traps to capture adult mosquitoes
  • Maintain screens on windows, doors, patios, and vents
  • Keep up recurring source reduction — dump and recycle containers that hold water
06 Chemical Control (last resort)

When pressure is high, professional treatment targets both larvae and adults with low-impact products.

  • Larvicides applied to standing water and adulticides in high-activity areas
  • Applied by a licensed technician following environmental guidelines
  • Products and modes of action rotated to prevent resistance
Do it yourself

Questions

Mosquito Control FAQ

How do I stop mosquitoes breeding in my yard?

Eliminate standing water — even a bottle cap's worth is enough for eggs. Empty and scrub containers, saucers, and bird baths weekly, keep gutters clear, cover rain barrels, and stock ornamental ponds with mosquitofish. Source reduction does more than any spray.

When is mosquito season in San Diego?

Activity climbs through the warm months, roughly late spring into fall. The invasive Aedes aegypti stays active well into fall and, unlike the local house mosquito, bites during the day — so the "season" now feels longer than it used to.

Are San Diego mosquitoes dangerous?

The common Culex mosquito can carry West Nile virus, and the invasive Aedes aegypti can transmit dengue and Zika if those viruses are introduced. Most bites are just itchy, but it is worth reporting heavy activity and dead birds to county vector control.

Do mosquito-repellent plants really work?

Only marginally. Citronella, lavender, and marigolds may help a little near where they are planted, but removing standing water, using screens, and applying repellent do far more to reduce mosquitoes than plants alone.
