Why One Mosquito Spray Never Lasts
Most Georgetown homeowners try the same thing first: a can of spray or a hose-end fogger from the store. It clears the yard for an afternoon, then the mosquitoes are back by the weekend. The reason is simple. You killed the adults flying around, but you did nothing about where they come from.
Mosquitoes breed in standing water, and a single teaspoon is enough. Every mosquito you swat is being replaced by dozens more hatching from water you probably cannot even see: a clogged gutter, a plant saucer, a low spot in the yard, an irrigation valve box. Kill the adults and ignore the water, and the cycle just restarts.
Kills the Adults, Misses the Source
Real mosquito control works on the whole life cycle. We find and treat the breeding sites, use larvicide to kill immature mosquitoes in the water before they ever fly, and apply a residual barrier to the shaded spots where adults rest during the day. That combination is why professional treatment holds for weeks while a one-time spray fades in hours.
Targets the Resting Spots That Matter
Store-bought foggers also miss the resting spots that matter. Adult mosquitoes spend the hot part of the day tucked under leaves, in dense shrubs, and along shaded fence lines, not out in the open where a homeowner sprays. A professional barrier treatment targets exactly those hidden resting areas, which is where the population actually sits between feedings.
Why do mosquitoes come back so fast after I spray?
Because spray only kills the adults you hit, not the larvae developing in standing water nearby. Mosquitoes go from egg to biting adult in about seven to ten days in Georgetown's summer heat, so a fresh wave hatches within a week. Lasting control means treating the breeding water and applying a barrier to resting areas, not just fogging the air once.
Why Georgetown Has a Serious Mosquito Problem
Georgetown's geography practically builds mosquito habitat. The San Gabriel River runs straight through town, and Lake Georgetown sits to the northwest, giving mosquitoes year-round breeding grounds along the water.
Homes near the river greenway, Blue Hole Park, San Gabriel Park, and the golf communities with water features deal with the heaviest pressure. The humid subtropical climate keeps mosquitoes active from spring well into fall, and peak activity hits at 80 to 90 degrees with high humidity, which describes most of a Central Texas summer. After a summer storm, every container and low spot in your yard becomes a breeding site within days.
This is not just a comfort issue. The Williamson County and Cities Health District runs mosquito surveillance traps across Georgetown from May through November, and in 2024 the county recorded four human cases of West Nile virus and a record-high 75 mosquito samples that tested positive for the virus. When a trap comes back positive, the health district sometimes conducts truck-mounted spraying, as it has near Edwards Park downtown. Mosquitoes here are a genuine public health concern, not just a nuisance.
The Mosquitoes We Treat in Georgetown
Two types of mosquito drive nearly all the problems in Georgetown, and they bite at different times of day, which is exactly why a single treatment window does not work.
Asian Tiger Mosquito (Aedes albopictus)
The Asian tiger mosquito is the most aggressive biter in Georgetown, recognizable by its black and white striped legs and body. Unlike most mosquitoes, it bites during the day, not just at dusk, so it ruins afternoon time in the yard. It breeds in small artificial containers, a flower pot, a bird bath, a toy, a clogged gutter, which means the breeding site is almost always in your own yard or a neighbor's. It can transmit West Nile virus, and is associated with Zika, dengue, and chikungunya. This is the mosquito behind most homeowner complaints in Central Texas.
Southern House Mosquito (Culex quinquefasciatus)
The Culex mosquito is the primary carrier of West Nile virus in Central Texas, and it bites at dusk and dawn. It breeds in stagnant, polluted water like storm drains, ditches, and neglected containers. Culex populations peak later in the season, from July through September, which is exactly when West Nile transmission climbs. Because it bites in the evening while the Asian tiger bites by day, protecting your family means covering both windows with a sustained program, not a single spray.
What kind of mosquitoes are biting me during the day?
Daytime biters in Georgetown are almost always Asian tiger mosquitoes, an aggressive striped species that breeds in small containers of standing water around your home. Unlike the evening-biting Culex mosquito that spreads West Nile virus, the Asian tiger is active in full daylight. If you are getting bitten in the afternoon in your own yard, the breeding source is likely right on your property.
Getting bitten in the yard during the day? That is the Asian tiger mosquito — and it is breeding on your property. Let us find the source.
(737) 379-5045 — Free InspectionThe Real Health Risks of Mosquitoes in Williamson County
Mosquitoes are the deadliest animal on earth because of the diseases they carry, and in Georgetown the risk is documented, not hypothetical.
West Nile Virus
West Nile is the leading cause of mosquito-borne disease in the United States and the main concern in Williamson County. The county health district confirmed four human cases and 75 virus-positive mosquito samples in 2024. Most people infected have no symptoms, but about one in five develop fever, headache, and body aches, and a small number develop serious neurological illness affecting the brain and spinal cord. Older adults and people with weakened immune systems are most at risk.
There is no vaccine or specific treatment for West Nile in people, which is why prevention is the only real defense. Reducing the mosquito population around your home, and cutting off the standing water where the Culex carrier breeds, directly lowers your household's exposure during the peak transmission months.
Other Mosquito-Borne Concerns
The Asian tiger mosquito present in Georgetown can also transmit Zika, dengue, and chikungunya. While local transmission of these is far less common than West Nile, the mosquito that carries them is here and active. Mosquito bites also cause allergic reactions and secondary skin infections from scratching, which hits children hardest. For pets, mosquitoes transmit heartworm, a serious and potentially fatal condition for dogs.
Is West Nile virus really a risk in Georgetown?
Yes. The Williamson County and Cities Health District recorded four human West Nile cases and a record 75 virus-positive mosquito samples across the county in 2024. The health district traps and tests mosquitoes from May through November and sometimes sprays when samples come back positive. West Nile is a real, monitored risk in Georgetown, which is why reducing mosquito breeding around your home matters for health, not just comfort.

Call (737) 379-5045 — Same-Day ServiceWhere Mosquitoes Breed Around Your Georgetown Home
Mosquitoes do not travel far. If they are biting you, they are almost certainly breeding within a few hundred feet, often right in your yard. These are the sources we look for and treat:
- Gutters: A clogged or slow-draining gutter holds water for days and is one of the most common breeding sites people miss.
- Containers: Saucers under potted plants, bird baths, buckets, toys, tarps, and trash can lids all collect enough water to breed hundreds of mosquitoes.
- Standing water in the yard: Low spots in the lawn, drainage inlets, and areas near the irrigation system that stay damp after rain or watering.
- Utility boxes: Irrigation valve boxes and water meter boxes hold hidden water that breeds mosquitoes out of sight.
- Resting areas: Dense, shaded landscaping and mulch beds where adult mosquitoes rest during the heat of the day.
- Nearby water: Proximity to the San Gabriel River, drainage ditches, or a neighbor's neglected pool multiplies the pressure on your property.
The Williamson County Health District's Fight the Bite campaign recommends draining standing water weekly. We take it further by treating the sources you cannot drain and applying a barrier that keeps adults from settling in.

Call (737) 379-5045 — Free Mosquito InspectionHow Our Georgetown Mosquito Control Process Works
Effective mosquito control attacks the whole life cycle, not just the adults. Here is how we do it.
Property Inspection
We walk your property and find every breeding site and resting area, the gutters, containers, low spots, utility boxes, and shaded beds. We show you what we found and where the mosquitoes are coming from, because source reduction is the foundation of lasting control.
Source Reduction and Larvicide
We eliminate or treat standing water we find. For water that cannot be drained, like drainage boxes and low areas, we apply EPA-approved larvicide that kills immature mosquitoes before they become biting adults. This breaks the cycle at its start.
Barrier Treatment
We apply a residual barrier treatment to the shaded areas where adult mosquitoes rest during the day, the undersides of leaves, dense shrubs, fence lines, and mulch beds. This knocks down the existing adult population and keeps new mosquitoes from settling on your property for weeks.
Ongoing Seasonal Protection
Because mosquitoes breed all season and a single teaspoon of new water restarts them, we set up recurring treatments through the active months. Most Georgetown yards do best on a treatment every three to four weeks from spring through fall to stay ahead of both the daytime Aedes and evening Culex.
How long does mosquito treatment last?
A professional barrier treatment typically keeps mosquitoes down for about three to four weeks before it needs refreshing, since the active ingredients gradually break down in sun and rain. That is why mosquito control in Georgetown works best as a recurring program through the season rather than a one-time spray. Each treatment also targets any new breeding sites that appear after rain.

Timing is the single biggest factor in how well mosquito control works. Starting before the population builds beats trying to catch up mid-summer.
In the Austin and Georgetown area, mosquito season effectively runs from late February or March through November. The Williamson County Health District begins trapping in May because numbers climb quickly after that. Starting a program in early spring suppresses the population base before it explodes, so you spend the summer ahead of the problem instead of chasing it.
☀️ Summer — Peak Pressure
Summer is peak pressure, with Asian tiger mosquitoes active all day and populations surging after every rain. From July through September, Culex numbers and West Nile risk climb, making evening protection especially important.
🍂 Fall and Winter — No Real Break
Even as fall arrives, mosquitoes stay active until the first real cold snap, and Georgetown's mild winters mean the break is short. A season-long program is far more effective than reacting to a swarm already in full force.
Best Time to Start: Early Spring. The Williamson County Health District begins mosquito trapping in May because populations climb fast. Starting in late February or March suppresses the base population before it explodes, so you spend the summer ahead of the problem instead of reacting to it. We can start any time, but earlier is always better.

Mosquito control in Georgetown typically runs from $75 to $150 per treatment, depending on the size of your yard and the number of breeding sites. Most homeowners choose a recurring seasonal plan, which costs less per visit and keeps mosquitoes down all summer. Your exact price comes from a free inspection with upfront pricing and no contracts.
Yes. Our treatments are applied by licensed technicians and are safe for children and pets once dry, usually within about 30 minutes. We use targeted barrier applications and EPA-approved larvicides placed where they work, not blanketed across play areas. Tell us about pets and any garden areas before we start so we treat accordingly.
Early spring is ideal, around late February through March, before the population builds. The Williamson County Health District begins mosquito trapping in May because numbers climb quickly after that. Starting early suppresses the base population so you stay ahead of the season. That said, we can start any time, since mosquitoes stay active into November here.
Yes. We offer special-event treatments timed a day or two before an outdoor gathering to knock down the adult mosquito population for the occasion. For lasting relief, a recurring seasonal plan works better, but a one-time treatment before a wedding, party, or backyard event makes a real difference.
Mosquitoes need only a teaspoon of standing water to breed, so even a tidy yard can have hidden sources: a clogged gutter, a plant saucer, an irrigation valve box, or a low spot that stays damp. Mosquitoes also fly in from a neighbor's yard or nearby drainage. A professional inspection finds the sources you cannot see and treats them.
Same day service is available across Georgetown and Williamson County when you call early, and we can often treat before a weekend or an outdoor event. Mosquito treatments are quick, and you can typically use your yard again within about 30 minutes of the barrier drying. We answer calls seven days a week.
Yes. The barrier treatment knocks down the adult mosquitoes resting on your property, so you get relief quickly. The larvicide and source reduction then prevent the next generation from hatching. Together they clear the current population and keep new mosquitoes from taking their place over the following weeks.
Yes. The Williamson County and Cities Health District confirmed four human West Nile cases and a record 75 virus-positive mosquito samples across the county in 2024. The evening-biting Culex mosquito is the main carrier, and risk peaks from July through September. Reducing mosquito breeding around your home lowers your exposure to the virus.
Those help a little in a small space but do not reduce the mosquito population or stop breeding. Citronella only repels mosquitoes within a few feet and fades fast. Real control means treating the breeding water and resting areas so there are fewer mosquitoes to begin with, which candles and repellents cannot do.
Yes. Our approach leads with source reduction, finding and eliminating breeding water, so we rely on less product overall. We use EPA-approved larvicides and targeted barrier treatments rather than blanket fogging, which protects pollinators and beneficial insects. This keeps your family safe and protects the San Gabriel River watershed while still clearing your yard.
