Friendly, effective mosquito pest control for Visalia homes and businesses.

About mosquitoes in the Central Valley
Mosquitoes are a serious issue across Visalia, Fresno, Madera, and Clovis. California has 53 established mosquito species in three main genera — Aedes, Culex, and Anopheles — including native residents like the Western encephalitis mosquito (Culex tarsalis), the Southern house mosquito (Culex quinquefasciatus), and the Western malaria mosquito (Anopheles freeborni). On top of those, invasive Aedes aegypti (yellow fever mosquito) and Aedes albopictus (Asian tiger mosquito) have become established in the Central Valley and Southern California — aggressive daytime biters that breed in tiny amounts of standing water. Effective mosquito control is never a one-time spray; it's a combination of source reduction, targeted barrier treatment, and ongoing monitoring through mosquito season.
Why it's a problem
Culex species in the Central Valley are the primary vectors for West Nile virus and St. Louis encephalitis — real public-health concerns during peak season. Invasive Aedes are notable for their ability to transmit Zika, dengue, and chikungunya, though local transmission of those remains rare in California. Even setting disease aside, constant biting shuts down backyards, patio dinners, and kids playing outside. Because females lay eggs in extremely small water sources — urban containers, plant saucers, and agricultural ditches — populations rebuild within days if breeding sites aren't addressed.
What homeowners can try first
Real tactics that can help with light pressure — and the honest limits of each.
- Dump and scrub anything holding water at least weekly — saucers, buckets, toys, tarps.Limit: Works if you catch every source, but Aedes eggs stick to container walls and hatch when water returns.
- Keep gutters clear and grade low spots that hold irrigation runoff.Limit: Removes obvious sites, but mosquitoes also breed in bromeliads, tree holes, and neighbor's yards.
- Use EPA-registered DEET or picaridin repellent when outdoors.Limit: Protects the person wearing it — not the yard or family members without it.
- Run an outdoor fan on the patio; mosquitoes are weak fliers.Limit: Helps in the fan's airflow only, not across the yard.
When to call Invictus
DIY is a first step. These are the moments to pick up the phone.
- Daytime biting activity — a sign of invasive Aedes
- Standing water sources you can't drain (drainage ditches, retention areas)
- Backyard events, weddings, or gatherings coming up
- Property is next to an irrigation canal, pond, or greenbelt
The professional process for mosquitoes
Every pest has a different biology — and a different process. Here's how we handle mosquitoes specifically.
- 01
Property inspection & source ID
We walk the property to find breeding sources — plant saucers, tarps, clogged gutters, irrigation pooling, and any container holding water.
- 02
Source reduction & larvicide
We remove or treat standing water. In containers that can't be drained (rain barrels, catch basins), we apply Bti larvicide — targeted only to mosquito larvae, safe for pets and pollinators.
- 03
Targeted barrier treatment
We apply a residual barrier product to the underside of foliage, shaded harborage, and resting spots where adult mosquitoes hide during the day.
- 04
Recurring service through mosquito season
Because populations rebuild fast, we recommend recurring visits every 3-4 weeks from spring through fall to keep pressure down.
Treatment methods — and what Invictus actually offers
Pest control companies use a wide range of methods, and not every company offers every one. Here's exactly what's standard in the industry, and where Invictus fits in.
- Invictus offers this
Source reduction & inspection
Identifying and eliminating standing water — the single most effective mosquito control step.
- Invictus offers this
Bti larvicide in standing water
Biological larvicide (Bacillus thuringiensis israelensis) placed in water sources that can't be drained. Kills larvae, safe for pets, fish, and pollinators.
- Invictus offers this
Residual barrier treatment on foliage
Targeted application to the underside of shrubs, hedges, and shaded resting sites where adult mosquitoes rest during the day.
- Invictus offers this
Recurring mosquito-season service
Every 3-4 weeks through the warm months to break the breeding cycle and keep populations down.
- Not a service we perform
Whole-yard fogging as a standalone service
One-off aerosol fogging with no source reduction or follow-up.
Fogging alone knocks down adults on contact but doesn't touch larvae or eggs — populations rebound within days without source reduction and recurring service.
