How to get rid of mosquitoes
Culicidae (Aedes, Culex, Anopheles, and others)
Mosquitoes are the US insect most worth taking seriously as disease animals: West Nile virus (Culex), and in some regions other arboviruses; Aedes species can transmit dengue, chikungunya, or Zika where those viruses circulate. CDC’s first tool remains source reduction — dumping standing water — plus screens and EPA-registered repellents. Backyard foggers at noon do not replace a weekly walk for gutters and toys. This page is not a substitute for local health-department virus alerts. If you have fever after mosquito exposure in a transmission area, that is a clinician, not a pesticide.
How to identify Mosquito
- Slender flies with scales on wings, long proboscis; only females bite.
- Larvae (“wrigglers”) in standing water; pupae (“tumblers”).
- Aedes often bite by day and use small containers; Culex often dusk and richer water — local species vary.
Signs of an infestation
- Larvae in gutters, saucers, tarps, and neglected pools.
- Bites at dusk or day depending on species.
- Local health alerts for virus activity.
Biology and why they show up
Complete metamorphosis in water. Flight range varies from a city block to miles. Climate and housing (screens, AC) change human exposure more than a single yard spray.
Health and property risk
Arboviruses, allergic reactions to bites, secondary infection from scratching. Not every itchy bump is a mosquito — ticks and bed bugs exist. Use CDC maps for disease, not folklore.
Proven control sequence
Work in this order. Skipping inspection or exclusion is why most “treatments” bounce back in a week.
- Dump water weekly. Gutters, toys, plant saucers, boat covers, spare tires. This is the control.
- Larvicide water you cannot dump. Bti dunks and similar labeled products in rain barrels and ornamental ponds. Do not oil a pond into a dead zone.
- Screens and personal protection. EPA-registered repellents, long sleeves at peak hours, intact door sweeps.
- Organized adulticiding is a district tool. When health departments spray, it is timed and targeted. A consumer fogger is not the same program.
Matching tools for these steps can be bought on Amazon. Buy the field kit.
Tools for mosquito source reduction
Dump water, screen what you cannot dump, Bti in the rest. Repellent is for the hike, not a substitute for the saucer under the pot.

Labeled product
Mosquito Dunks (Bti larvicide)
Treat standing water you cannot dump: birdbaths, gutters, unused pools, rain barrels. Bti hits larvae. A backyard fogger does not replace emptying the saucer under a pot.
Hardware
Window screen repair kit
A torn screen is a mosquito and fly door. Patch or respline. Attic vents still need hardware cloth, not fiberglass, if rodents are the pressure.
Labeled product
EPA-registered insect repellent
DEET or picaridin on skin as the label allows, plus a shower and a full-body check. A yard spray is not a hike protocol. Tweezers still belong in the kit.
Prevention that actually sticks
- Maintain pools; a green pool is a Culex factory.
- Fix screens after storms.
When to hire a licensed professional
Abandoned pools, septic, and wetlands need agencies or mosquito-control districts. Travel medicine is a clinician.
United States and Tier 1 notes
West Nile is a continental US story with local intensity. Southern Aedes albopictus and aegypti change the daytime-bite picture. Alaska still has intense seasonal mosquitoes without the same virus mix. Tropics (Singapore, Florida south) are year-round source-reduction cultures.
Common questions
Do ultrasonic yard stakes work?
CDC and EPA do not treat them as a replacement for dumping water and using registered repellents.
Are citronella candles enough?
They may reduce bites in a small radius for some people. They do not control larvae in a gutter.
