Mosquito, No-See-Um & Gnat Control in Southern Utah
Getting eaten alive in your own yard? We stop mosquitoes, biting midges, and gnats at the source — including the invasive ankle-biting mosquito now spreading across Washington County — so you can use your outdoor space again.
Why mosquitoes and gnats are worse than ever in St. George
If it feels like there are more biting bugs around your home than in years past, you're not imagining it. Warm temperatures, monsoon moisture, and irrigated desert landscaping have created ideal breeding conditions across St. George, Washington, Hurricane, Ivins, and Santa Clara — and a new invasive mosquito has made things noticeably worse.
⚠ The "ankle biter" invasion: invasive Aedes aegypti in Washington County
Many homeowners blaming "no-see-ums" for bites around their ankles and wrists are actually dealing with Aedes aegypti — an invasive, container-breeding mosquito the Southwest Mosquito Abatement District has confirmed across St. George, Santa Clara, Washington City, Hurricane, and Springdale.
Unlike our native mosquitoes, this species bites during the daytime, feeds almost exclusively on humans, and breeds in tiny amounts of water — a plant saucer, a bottle cap, a forgotten bucket. Its eggs can survive dry for long stretches and hatch to adults in as little as 4–5 days once water returns. That fast cycle is why store-bought sprays fail and why source-targeted treatment matters.
Most people first notice the problem at dusk on the patio, in shaded landscaping, or as clouds of tiny gnats near doorways and potted plants. Indoors, gnats almost always trace back to overly damp potting soil or slow, dirty drains.
The three pests we target — and how to tell them apart
They get blamed interchangeably, but each one breeds and behaves differently. Correct identification is what makes treatment actually work.
Mosquitoes
Native species bite at dawn and dusk; the invasive Aedes aegypti bites all day and targets ankles and wrists. They breed in standing water of any size.
While Aedes can carry diseases elsewhere, local health officials report it has not been found carrying disease in Washington County — the immediate problem is relentless, welt-raising bites.
No-See-Ums (Biting Midges)
Small enough to slip through standard window screens, with a bite far bigger than their size. They breed in moist soil, mud, and shaded organic matter around irrigated landscaping and water features.
Many "no-see-um" complaints in our area turn out to be the invasive ankle-biting mosquito instead — we identify which you actually have.
Gnats
Fungus gnats and similar species swarm around damp soil, drains, and decaying organic material. More nuisance than danger, but maddening indoors and around entryways.
Control means drying out and treating their breeding sites, not just swatting the swarm.
The mosquito life cycle — and where we break it
Killing the adults you see is only a quarter of the job. Every mosquito passes through four stages, and lasting control means hitting more than one of them.
1. Egg
Laid on or near standing water — or on the sides of containers, where Aedes eggs wait, dry, for the next rain or watering.
2. Larva
Hatch and develop in standing water. This is where larvicide treatment stops the next generation before it can fly.
3. Pupa
A short transitional stage, still in water. Source reduction here prevents emergence.
4. Adult
The biting stage. Barrier and fogging treatments knock these down on the vegetation where they rest.
In peak summer heat, that entire cycle can finish in under a week. That's why one-and-done DIY sprays never hold — and why we treat the breeding sites and the adults together.
A complete mosquito program, not a one-time fog
We combine the same professional methods the experts use, tuned to Southern Utah's desert yards and the Aedes container-breeding problem.
Source Reduction
The single most effective control method. We find and eliminate the hidden standing water producing your mosquitoes — the step most homeowners miss.
Larvicide Treatment
For standing water that can't be drained, we treat the water directly to kill larvae before they ever become biting adults.
Barrier / Adult Treatment
We treat the shaded vegetation, eaves, fence lines, and harborage where adult mosquitoes rest between feedings, reducing the population that reaches you.
Targeted Fogging
For high-activity zones and pre-event knockdown, fogging rapidly drops adult numbers right where you spend time outdoors.
What working with Bug Blasters looks like
Inspect & identify
We walk your property to confirm what's actually biting you and pinpoint breeding sites — standing water, irrigation leaks, dense shaded landscaping, and container hideouts the Aedes mosquito loves.
Treat the source and the adults
We combine source reduction, larviciding where needed, and barrier treatment of resting zones to interrupt the cycle — not just knock down what's flying today.
Protect through the season
Mosquito pressure rebuilds as new adults emerge. Regular service from roughly March through October keeps populations suppressed, with free callbacks between visits for recurring customers.
Dump the water, starve the mosquitoes
The invasive ankle-biter can breed in a bottle cap of water, so source reduction at home dramatically improves your results. Walk your yard weekly and empty or treat these common culprits:
- Flower pots and plant saucers
- Clogged or slow-draining gutters
- Bird baths and decorative ponds
- Kids' toys, buckets, and tarps
- Pet bowls (refresh daily)
- Old tires and outdoor clutter
- Irrigation leaks and low spots
- Outdoor drains and catch basins
Seeing gnats indoors?
Check potted plants for overly damp soil and let them dry between waterings, and make sure sink and floor drains are clean and flowing. Slow drains and soggy soil are the top breeding sites for indoor gnats.
Why Southern Utah neighbors call us first
We treat the source, not just the swarm
Fogging adults alone is temporary. We target breeding sites and resting zones so populations actually drop and stay down.
We know the Aedes problem
We understand how this invasive container-breeder behaves in local yards — and why generic spraying doesn't stop it.

Mosquito & gnat control FAQs
Why do I suddenly have so many mosquitoes this year?
Warm temperatures, monsoon rains, and irrigated desert landscaping create constant breeding conditions, and an invasive container-breeding mosquito has become established across Washington County. Together they've pushed biting-insect activity well above what most residents are used to.
Are these "no-see-ums" or mosquitoes biting my ankles?
Often it's neither what you think. Local mosquito experts note the invasive Aedes aegypti is frequently mislabeled as a no-see-um because it flies low and bites ankles and wrists during the day. Part of our visit is identifying exactly which pest you have so the treatment fits.
Do these mosquitoes carry disease?
Aedes aegypti can transmit diseases in other parts of the world, but local health officials report it has not been found carrying disease in Washington County. For now the real problem here is aggressive, welt-raising biting — which is reason enough to get it under control.
Do mosquito treatments actually work?
Yes, when they target the whole life cycle rather than just the adults. By combining source reduction, larvicide where needed, and barrier treatment of resting areas, we reduce the population that reaches you and keep it down with regular service.
How soon will I notice fewer mosquitoes?
Most homeowners see a clear drop in biting within a day or two as we knock down the adults. Because new adults keep emerging from any remaining water, ongoing seasonal service is what keeps numbers low through the summer.
What time of year should I start mosquito service?
Southern Utah's mosquito season generally runs March through October. Starting early, before populations build, makes the whole season easier to control — but we can help anytime, including mid-season knockdown.
Is the treatment safe for my kids and pets?
Yes. We use EPA-registered products applied by licensed technicians. Once the application has dried — typically about 30 minutes — treated areas are safe for children and pets.
How are gnats getting inside my house?
Indoor gnats are usually fungus gnats that trace back to overly damp potting soil or slow, dirty drains. Letting plant soil dry between waterings and cleaning drains removes their breeding sites. We can treat both indoors and out.
Can you treat before a party or event?
Yes. Tell us your date and we'll schedule treatment a day or two ahead so your yard is comfortable. Same-day service is often available during peak season.
Do I need a contract?
No. We never require contracts. Recurring seasonal customers get free callbacks between scheduled services if activity returns.
