Mosquito control across San Diego County

Aedes aegypti and Aedes albopictus are invasive species that became established in San Diego in the last decade. Unlike native mosquitoes, they bite during the day, are aggressive, and can transmit diseases like Zika, dengue, and chikungunya. They breed in extremely small amounts of water, sometimes less than a tablespoon.

Our applications target dense shaded foliage where mosquitoes rest, not flowering plants where bees forage. We use pyrethrin-based products that break down quickly in sunlight and avoid blooming flowers and herb gardens. Timing matters, we typically treat in early morning or evening when pollinators are less active.

Adult mosquito knockdown lasts 21–30 days under typical conditions. Heavy rain or aggressive irrigation can wash product off and reduce effectiveness. Monthly visits during mosquito season (April–November) maintain consistent control.

Realistic expectation: bite frequency drops by 75–90% in treated areas. Mosquitoes from neighboring untreated yards can still travel in, so you may see occasional bites near property lines or after heavy rain. Reducing breeding sites in your own yard is the single biggest factor.

Yes. Our monthly mosquito spray service runs through the season, April to November, and most yards do best on a recurring plan rather than a single spray. A professional mosquito exterminator targets both the adults resting in your foliage and the larvae breeding in standing water, which is why recurring service holds the population down far better than spraying once. One-time backyard event treatments are available too.
