Mosquito control comes with the full plan.

Here is the whole price conversation. Georgetown homes get mosquito control inside the General Pest + Rodent + Mosquito plan, from $166 a month for a single-family house, and that same visit handles ants, spiders, roaches, scorpions, wasps and rodents. There is no separate mosquito add-on, whether you back onto the river or water like Sun City. If the mosquitoes come back early, so do we, at no charge.

Our approach

How we treat mosquitoes in Georgetown.

Mosquito control is two jobs done together: drop the adults where they rest, remove the water making replacements.

Find and remove the water

We walk the property and identify every breeding site: saucers, gutters, tarps, ruts, low spots. What can be emptied gets emptied.

Treat the resting sites

A targeted application to the undersides of foliage, dense shrubs, fence lines, under decks and any shaded harborage adults use during the day.

Hold the barrier

We return on a recurring schedule through the season, because a treated yard next to untreated river corridor needs the barrier maintained.

Why mosquito pressure is so high in Georgetown.

Two rivers meeting in one town is the short explanation for Georgetown's mosquito pressure. The North and South Forks of the San Gabriel hold shaded, slow-moving water through the middle of the city, and the surrounding parks and greenbelts keep humidity and insect volume high. Sun City and the other irrigated neighborhoods add the container and standing-water problem: daily watering, decorative water features, plant saucers and low spots that stay wet on ground that drains poorly once the limestone is saturated.

Georgetown's housing runs from one extreme to the other, and the pest work follows. Downtown has one of the best-preserved Victorian commercial districts in Texas plus surrounding homes over a century old, with all the gaps, voids and original construction details that age brings. Sun City is an enormous, meticulously landscaped and irrigated retiree community. And Wolf Ranch, Parkside on the River and Rancho Sienna are new construction on freshly graded ground. Three completely different problems inside one city.

This is where the hose-end sprayer from the garage runs out of talent. Adult mosquitoes spend the whole day clocked out on the undersides of leaves, deep in the shrubs, under the deck and along the fence line, which is nowhere near the open lawn most people spray. Real control means treating the shady spots where they nap and dumping the standing water raising the next batch. A mosquito needs about a bottle cap of water to start a family, which is why the EPA leads its pest management guidance with source reduction, so that clogged gutter is not a gutter, it is a maternity ward. Do only one of those two jobs and you get the same result as mowing half a lawn.

Seasonal pattern

When is mosquito season in Georgetown?

Mosquitoes here get a long run at it. Activity lifts in April, sits high all summer, and keeps going into November. The late summer stretch is when West Nile detections usually climb.

Typical mosquito activity in Georgetown by month Mosquito activity is very low in midwinter, climbs from April as temperatures rise, and runs high from June through October with a late summer peak in August and September. Austin Public Health traps and tests mosquitoes for West Nile virus from May through November, which is the official local season.

The real fix
Standing water

A bottle cap of water is enough. Treatment works far better once the breeding sites on your property are gone.

From real jobs

Our own photos from Georgetown jobs. Not one of these is a pond or a creek. They are all containers, which is why source reduction beats spraying every time.

Know your pest

The mosquitoes biting you in Georgetown.

Every mosquito species finds something to like in Georgetown. Container breeders find plant saucers and water features in Sun City and hundred-year-old gutters downtown. The dusk-biting West Nile carrier works the slow water along both forks of the San Gabriel. Floodwater species sit in the soil on the big lots out toward Berry Creek and Serenada, waiting for a storm. Which one is chewing on you decides when and where we treat, so your technician confirms the species on site first.

Asian tiger mosquito (Aedes albopictus) on a dry stem, showing the single white stripe down its back and banded legs

Asian tiger mosquito

Aedes albopictus

Striped black and white, bites at 2pm and holds a grudge. This is the one turning Sun City patios into no-go zones by early afternoon, because it breeds within a few yards of where it bites: the saucer under the potted citrus, the birdbath, the fountain basin that stopped circulating. It rarely flies far, so a Georgetown tiger mosquito problem is nearly always coming from your own lot or the neighbor's. Asian tiger mosquito identification guide (Texas A&M)

Culex quinquefasciatus

The main West Nile virus vector in Central Texas (CDC's West Nile virus overview). Bites at dusk and after dark, breeds in stagnant water rich in organic matter such as storm drains, detention ponds and neglected pools.

Floodwater mosquito (Aedes and Psorophora) perched on a dry stem, showing its long legs and pale-banded abdomen

Floodwater mosquitoes

Aedes/Psorophora spp.

Lay eggs in soil that only hatch when heavy rain floods it. This is why a huge, sudden wave of mosquitoes shows up three to five days after a big storm. Texas fly and mosquito guide (Texas A&M)

Floodwater mosquito. Appears in numbers a week after heavy rain.

A note on bites and stings. Reactions vary from person to person, and any bite or sting can cause a serious reaction in someone sensitive to it. Nothing here is medical advice. If you are bitten or stung and feel unwell, or the reaction spreads or does not settle, contact a doctor or Poison Control. If breathing or swallowing is affected, treat it as an emergency and call 911.

Warning signs

You do not need a diagnosis. You need a plan.

Whether you have mosquitoes in Georgetown is settled. Where they are living is the real question, and the answer changes from a Victorian lot downtown with old gutters to a Sun City yard with a fountain and daily watering. Call and walk us through what you see. Usually we can tell over the phone if it needs a same-day visit or can ride the regular route.

  • Bites while doing yard work in the middle of the day
  • Standing water in plant saucers, toys or tarps
  • Water sitting in gutters or downspout extensions
  • A low spot or rut that stays wet for days
  • Mosquitoes rising when you brush past shrubs
  • Heavy biting pressure at dusk on the patio
  • Decorative fountain or water feature on an irrigated Sun City lot
  • Low spots on saturated limestone along the San Gabriel forks

Your Georgetown neighborhood is on the route.

River first, then water bills. San Gabriel Heights and Parkside on the River sit right on the forks, so adults come in off the corridor every evening no matter how clean the yard is. Sun City is the other end of the problem: irrigated lawns, fountains and saucers producing mosquitoes on site. Wolf Ranch is new construction on graded ground that has not settled yet. A mosquito exterminator in Georgetown has to read the lot before treating it.

Ask us about mosquitoes in Georgetown.

How much does mosquito control cost in Georgetown, TX?

Mosquito service is included in our General Pest + Rodent + Mosquito plan, starting at $166 per month for a single-family home in Georgetown. That covers the mosquito barrier plus general pest and rodent control on the same visit. Larger lots are priced higher, and we confirm your number with a free on-site quote.

How long does a mosquito treatment last?

Two to four weeks, depending on rain and heat. Heavy downpours strip product off foliage and refill every container in the yard simultaneously, which is why this is a recurring service rather than a single visit.

Is mosquito treatment kid, pet and pollinator friendly?

Our treatments are pet and kid friendly when applied correctly. We treat foliage undersides and shaded harborage, not open blooms, and we avoid flowering plants where pollinators forage. Keep kids and pets off treated areas until dry, roughly 30 minutes. Your technician will tell you if any area needs longer. If you keep bees or grow vegetables, tell us and we will flag those as no-treat zones.

Do you treat standing water, or just spray?

Both, because spraying alone is only half the work. We inspect for breeding sites first, empty what can be emptied, then treat the shaded harborage where adults rest.

Can you get rid of mosquitoes if I back onto a creek or greenbelt?

We can make your yard usable, and that is the honest version. Properties along the San Gabriel deal with constant re-invasion, so anyone promising zero mosquitoes is overselling. Going from unusable to comfortable is very achievable.

When should I start mosquito service in Georgetown?

February or March, ahead of the first generation maturing. Getting in early suppresses the population before it builds, which beats chasing it in midsummer.

Does Sun City's daily irrigation make mosquito treatment wear off faster?

Some, and we plan for it. Sprinklers hitting treated shrubs every morning will shorten the barrier's life the same way rain does, so we aim for the undersides of leaves and the shaded sides of the house that sprinklers mostly miss. The bigger effect of irrigation is upstream: a lot that never dries out keeps every saucer, drain and fountain basin topped up. On a Sun City property the source reduction half of the visit does more work than the spray.

Is a century-old house near downtown Georgetown worse for mosquitoes than new construction?

Different, not worse. An old downtown lot has mature shade, original gutters and decades of accumulated containers, so it breeds daytime biters right at the house. A new Wolf Ranch yard has almost no shade for adults to rest in, but the graded ground has not settled, so ruts and buried downspout extensions hold water after every storm. The old house needs its gutters and shade treated. The new one needs its drainage sorted. Same plan, different checklist.
