Mosquito Control in California & Nevada

Professional mosquito control gets rid of backyard mosquitoes by hitting them at every life stage: removing and treating the standing water where they breed, installing a station that turns egg-laying females against the rest of the population, and applying a longer-lasting barrier to the shady spots where adults rest. Since 1950, Clark Pest Control has used this approach to take back yards across California and Nevada, with a free inspection and a satisfaction guarantee.

Your county vector control district treats public waterways, but it cannot reach the breeding sources on your own property. That is the gap Clark fills.

How to Tell What Kind of Mosquito Problem You Have

Two very different kinds of mosquitoes share California and Nevada yards, and telling them apart explains when and where you get bitten:

  • Native Culex mosquitoes (including Culex tarsalis and Culex quinquefasciatus) bite mainly at dusk and dawn and breed in standing water that sits for several days. They are the main carriers of West Nile virus.
  • Invasive Aedes mosquitoes (Aedes aegypti and Aedes albopictus), the "ankle-biters," bite during the day, come after people aggressively, and breed in containers as small as a bottle cap. Their eggs survive months of dry weather, so they rebound fast.

If you are getting bitten in the afternoon near your patio or garden, you are almost certainly dealing with invasive Aedes, and the breeding source is close by. These mosquitoes do not fly far, so the water is usually on your own lot or a neighbor's. For background, see Clark's mosquito identification guide, the California Department of Public Health invasive Aedes page, and the state West Nile virus tracker.

Get Rid of Mosquitoes Fast - and Keep Them from Coming Back

Mosquitoes multiply quickly and are tough to control on your own, so we treat the whole life cycle and hold the pressure down through the season. Our mosquito control service includes:

  • Free property inspection to find every breeding source and resting area
  • Standing-water reduction and larvicide to stop mosquitoes before they ever fly
  • A mosquito defense station that spreads a biological fungus through the local population
  • Barrier treatment of foliage and shaded resting areas for longer-lasting control
  • Recurring seasonal service timed to the mosquito pressure in your area
  • Year-Round Pest-Away coverage to bundle mosquito protection with your other pest control

How Our Mosquito Control Works

Mosquitoes are hard to control because they breed in water you cannot always see, and the females keep laying eggs all season. We use a three-step approach that hits them at different life stages instead of a single spray:

  1. Remove and treat breeding sites. Your technician walks the property and removes standing water wherever possible. For water that has to stay, like a pond or a low spot that keeps filling, we apply larvicide to kill the larvae before they become biting adults.
  2. Install and service a mosquito defense station. We set up a station that targets the egg-laying females, the only mosquitoes that bite. It coats them with a biological fungus that kills them, but not before they carry it to other breeding sites as they move around laying eggs. The treatment turns the mosquitoes' own behavior against the population and reaches hidden water you would never find on your own.
  3. Treat the resting areas. Finally, we apply a longer-lasting barrier product to the foliage and shady spots where adult mosquitoes rest during the day, like under decks, eaves, and dense shrubs. This broadcast treatment keeps knocking down adults between visits.

One service brings the numbers down, but mosquitoes breed all season long. We keep your property on a recurring schedule through the warm months so new mosquitoes never get a foothold.

How to Prepare for Your Mosquito Service

A few minutes of prep makes each visit work better. Before your technician arrives:

  • Empty or cover anything holding water: buckets, toys, plant saucers, tarps, and wheelbarrows.
  • Pick up pet bowls, and refill them with fresh water after the service.
  • Clear leaves from gutters and drains so water cannot pool.
  • Mow the lawn and trim dense shrubs so we can reach the shady resting spots.

One thing to skip: do not set off a store-bought fogger right before service. It scatters adult mosquitoes into deeper hiding spots and makes the professional treatment less effective.

How to Prevent Mosquitoes in Your Yard

Most backyard mosquitoes come from water on your own property, so prevention starts with denying them a place to breed:

  • Walk your yard once a week and dump anything holding water. A bottle cap is enough for Aedes.
  • Keep gutters clear, and grade low spots that stay wet after rain or irrigation.
  • Change birdbath and pet water every few days.
  • Screen rain barrels and cover stored containers.
  • Stock ornamental ponds with mosquito fish, or ask your vector control district about free ones.
  • Run a fan on the patio. Mosquitoes are weak fliers and avoid moving air.

These habits lower the pressure, but they will not clear an established population on their own. Pair them with recurring service or Year-Round Pest-Away for steady control.

Where We Provide Mosquito Control

We provide mosquito control for homes and businesses across California and Nevada through 30+ local branches. Pressure runs heaviest in the irrigated Central Valley and anywhere standing water collects, so a local technician who knows your area makes a real difference.

Frequently Asked Questions About Mosquito Control

How much does professional mosquito control cost?

Mosquito control pricing depends on the size of your property, how much standing water and shade it has, and how heavy the mosquito pressure is. That is why we start with a free inspection. Once a technician walks your yard and finds the breeding sources, you get a clear quote before any work begins, with no obligation.

Does professional mosquito control actually work?

Yes, when it targets the whole life cycle instead of just spraying the adults you can see. Most homeowners notice a clear drop in biting after the first service. Store-bought foggers kill visible adults but miss the eggs and larvae in hidden water, so the population bounces back within days. Our breeding-site treatment, defense station, and barrier application break that cycle and keep working between visits.

Do I need a mosquito exterminator, or can I get rid of mosquitoes myself?

You can lower mosquito numbers yourself by dumping standing water every few days, but that rarely solves a real problem, because invasive Aedes mosquitoes breed in spots as small as a bottle cap and often come from a neighbor's yard. A professional mosquito exterminator finds the hidden breeding sources, treats the water and the resting areas, and returns on a schedule so the population does not rebuild. Think of it as ongoing suppression, not a one-time spray.

How often do I need mosquito treatment?

Mosquitoes breed all season, so one treatment is not enough. We service most properties on a recurring schedule through the warm months, usually every few weeks, and adjust the timing to your yard and the local mosquito pressure. Year-round plans are available where mosquitoes stay active longer.

When is mosquito season in California and Nevada?

In most of California and Nevada, mosquito activity climbs in spring, peaks in the hot summer months, and tapers off after the first frost. A mild, dry winter can start the season early. Because West Nile virus risk is highest in late summer, that is when consistent treatment matters most.

Are your mosquito treatments safe for kids, pets, and bees?

Yes. We use IPM-based, GreenPro certified methods and apply products only where mosquitoes breed and rest, following the label and EPA guidelines. The defense station targets mosquitoes specifically, and your technician will point out anything you need to know about flowering plants and re-entry before treating.

Why am I getting bitten in my own yard during the day?

If mosquitoes are biting you in the afternoon, they are almost certainly invasive Aedes, the day-active ankle-biters that have spread through the Central Valley and beyond since the mid-2010s. Unlike California's native Culex mosquitoes, which bite around dusk and dawn, Aedes breed in tiny containers close to home and rarely fly far. That is why the source is usually in your own yard or right next door.

How do I keep mosquitoes out of my yard between visits?

Empty and scrub anything that holds water at least once a week: plant saucers, buckets, toys, tarps, clogged gutters, and pet bowls. Keep grass and shrubs trimmed so adults have fewer shady places to rest. These habits will not replace treatment, but they make each service more effective and keep new mosquitoes from establishing between visits.

Do mosquitoes in California carry disease?

Some can. West Nile virus is the most common and serious mosquito-borne disease in California, carried by native Culex mosquitoes, and the state reports more cases than anywhere else in the country. The invasive Aedes mosquitoes now in California can carry dengue, Zika, and chikungunya. Most bites never transmit anything, but reducing the mosquitoes around your home lowers the risk for your family and pets.

Isn't my county mosquito and vector control district enough?

Your county mosquito and vector control district does important work, but it focuses on public areas, waterways, and community-wide surveillance. It cannot treat the breeding sources on private property. The mosquitoes biting you in your backyard usually come from water on your own lot or a neighbor's, which is exactly what our service targets.

What Our Customers Say

"Clark Pest Control is the best service I have ever had! My service tech, Dion, swept my fence and front porch walls for spider webs right after he sprayed on his first service. When my husband told him he is a mosquito magnet, Dion set out mosquito traps for us. Take a chance on Clark Pest Control. Ask for Dion to be your tech. I promise you won't regret it."

Michelle R., Temecula, CA

"I recommend Clark Pest Control. Eric always does a great job. If I have any issues, he always addresses the problem. He took care of my problem with ants in the backyard. I didn't even know I had a problem. Thank you."

Sybil E., Lancaster, CA

"I recently had my first service with Clark Pest Control, and I couldn't be more pleased. Ari, the sales rep, took the time to explain the treatment plan and answered all of my questions. My technician, Diego, confirmed his arrival time first thing in the morning and responded promptly to every text throughout the day. He thoroughly treated the property, wiped down all of the eaves, and made sure everything was done properly. The initial service took a little over 45 minutes, which showed real attention to detail. After seven years with another company, where technicians were in and out in 15 minutes or less, this level of service was refreshing. The customer service has been far superior, and the pricing is more competitive too. I highly recommend Clark Pest Control."
