When is this pest active?
Pest activity follows the weather, so timing matters. Treating inside the active window is usually cheaper and more effective than waiting for the problem to grow.

What do bites and stings from this pest look like?
What can a bite tell you, and what can it not?
Bites from different insects often look alike. The same insect can cause very different reactions in different people, and many people never react at all. A bite cannot identify a species.
This is general information, not medical advice. If you are worried about a bite or a reaction, see a doctor.
What should you do right now?
These are steps a homeowner can take today, before anyone visits. None of them replace a licensed local company once an infestation is established.
- Walk your property for water: Tip out anything holding water: saucers, toys, buckets, tarps, wheelbarrows, tires, bins.
- Clear gutters and downspouts: Blocked gutters are one of the most common residential breeding sites and are easy to miss.
- Note where you get bitten: Tell the technician which part of the yard and what time of day. It points to the resting habitat.
- Mention ponds, pets and vegetable gardens: These change product selection, so say where they are before treatment.
- Plan around treatment day: Ask how long to keep children, pets and outdoor dining off treated foliage.
Want a local company to handle Mosquitoes?
PestChief is free to the homeowner. Your request goes to one independent local pest control company that covers your ZIP code and handles that pest, not to seven. That company contacts you directly to confirm details and arrange a visit.
What does treatment typically cost?
What you pay depends on the pest, the size of the property and how far the problem has spread.
These are national estimates drawn from published industry sources, not PestChief quotes. Every figure states the basis it is measured on. The real price comes from the company that inspects your home.
When should you call a pest control company?
Call when the job has outgrown a homeowner fix. The usual signs are damage to wood, wiring or insulation, activity that returns within weeks of treating it, a nest or colony you cannot reach safely, and any pest that bites or stings people living in the home. Specialty pests need specific state licensing to treat, so the work has to go to a licensed company.
PestChief does not spray, trap or treat pests. Give your ZIP code and the pest you are seeing, and PestChief passes the request to one independent local pest control company that covers your address and handles that pest. That company contacts you directly to confirm details and arrange a visit. The service is free to the homeowner, and the company sets its own price.
Why does mosquito control focus on water?
Mosquitoes need standing water to develop, and some of the species that bite people most persistently breed in remarkably small amounts of it. The CDC's guidance on reducing mosquitoes around the home centers on eliminating that water weekly, because a container-breeding population is produced on your property rather than flying in from a marsh.
This is why a company that only sprays the yard and never walks the property looking for water is doing half the job. Gutters, tarps, plant saucers, toys, tires, clogged drains and corrugated downspout extensions all produce mosquitoes.
| Site | Why it breeds mosquitoes | What to do |
|---|---|---|
| Plant pot saucers | Holds water for days after watering | Empty weekly or remove |
| Clogged gutters | Standing water in the low run | Clean twice a year |
| Corrugated downspout extensions | Water sits in the ridges | Replace with smooth pipe or drain the low end |
| Tarps and covers | Pools in the folds | Pull tight or store dry |
| Bird baths and pet bowls | Refilled but not emptied | Change water twice a week |
| Tree holes and bamboo stumps | Natural container habitat | Fill or have treated with larvicide |
| Neglected pools and rain barrels | Large sustained larval habitat | Screen, treat with larvicide, or restore circulation |
What does a professional mosquito treatment include?
- A property walk to find and eliminate or treat larval habitat
- Larvicide in water that cannot be drained, such as catch basins or ornamental ponds
- Targeted application to shaded resting areas: dense shrubs, ivy, fence lines, under decks
- Monthly or three-weekly repeat visits through the local season
- In-ground or misting system options where mosquito pressure is extreme
- Advice on standing water you can remove yourself between visits
Why do I still get bitten after a treatment?
A barrier treatment reduces the resident population on your property. It does not create a force field. How far a mosquito travels depends on the species. Aedes mosquitoes, the container breeders responsible for most backyard biting, are weak, short-range fliers that stay close to where they hatched, which is why standing water on or beside the property is usually the source. Other species, Culex among them, range further and fly in from neighboring yards, drainage ditches and public land.
A realistic expectation is a large reduction in biting pressure in treated areas, not zero mosquitoes. Any company promising complete elimination is overselling.
Why mosquito control matters beyond the itching
The CDC identifies mosquitoes as vectors for viruses including West Nile virus, which is the most common mosquito-borne disease in the continental United States, along with regionally reported dengue, Zika and chikungunya and the rarer encephalitis viruses. CDC surveillance covering 2009 to 2018 found that 89% of US West Nile cases had onset between July and September. Dog heartworm is also mosquito transmitted, which is a reason pet owners take yard mosquito pressure seriously.
Reducing breeding sites is a public health measure as well as a comfort measure, and it is the part of mosquito control a homeowner can genuinely influence.
When should mosquito service start?
Start when night temperatures stay reliably above roughly 50 degrees Fahrenheit, because that is when adults become active and breeding resumes. In the Deep South, Gulf Coast, Florida and southern Texas the season can run most of the year. In the northern tier it is typically May through September.
Starting early in the season matters more than treating aggressively in August, because early treatment suppresses the first generations that would otherwise multiply all summer.
Frequently asked questions
How much does mosquito control cost?
Monthly seasonal service is commonly quoted at $60 to $120 per visit, which works out to roughly $400 to $900 for a season, and single-visit treatments before an event typically run $100 to $200. These are national estimates from published sources, not a PestChief quote, and the independent local pest control company that inspects your property sets its own price.
How long does a mosquito treatment last?
Most barrier treatments are designed to suppress adults for about three to four weeks, which is why service is scheduled monthly. Heavy rain, irrigation and rapid plant growth shorten that window.
Is mosquito spraying safe around children and pets?
Licensed applicators use registered products and will give you a re-entry time, typically until treated foliage is dry. Tell the company about pets, ponds, beehives and vegetable gardens so product and placement can be adjusted.
Do mosquito traps and zappers work?
Bug zappers mostly kill non-biting insects and are not an effective mosquito measure. Some CO2-based traps reduce local populations modestly, but eliminating standing water remains the highest-value action.
Do I need mosquito service if my yard has no standing water?
Possibly. Mosquitoes fly in from neighboring properties, storm drains and drainage ditches, and shaded resting habitat on your property keeps them there. A resting-site treatment helps in that situation.
What diseases do mosquitoes spread in the US?
West Nile virus is the most commonly reported mosquito-borne disease in the continental United States, with regional reports of dengue, Zika, chikungunya and rarer encephalitis viruses. Mosquitoes also transmit heartworm to dogs.
When should I start mosquito service?
Begin when nights stay above roughly 50 degrees Fahrenheit. Early-season treatment suppresses the first generations, which keeps mid-summer numbers far lower than starting in July.
