About MosquitoZone
MosquitoZone gives every U.S. town a single, plain mosquito forecast for the day, updated daily. It exists because mosquito pressure is intensely local and seasonal, but most tools are either a nationwide map with no local detail or a thin lead-generation page. We wanted the opposite: a calm, sourced number you can check before you head outside, with the reasoning shown, not hidden.
What it is
A daily 0 to 100 bite-risk estimate combining local weather, recent rain, the season, and nearby breeding habitat, plus a West Nile and EEE overlay and which mosquito species drive risk in your town. Every input is public data from named sources, and the methodology explains exactly how they combine. We cover every town across 38 states, so the score reflects the place you actually live rather than a state or regional average.
What it isn't
It is a defensible heuristic, not a validated epidemiological model, and not medical advice. It estimates how favorable conditions are for mosquito activity in a place on a given day. It cannot tell you whether a specific mosquito carries disease, and it is no substitute for a healthcare professional. If you feel unwell after mosquito bites, contact a professional and see CDC guidance.
Where the data comes from
Nothing here is invented or scraped from other forecasters. Each town's score is built from public data, cited on the pages it feeds:
- Local weather from Open-Meteo: temperature, wind, humidity, and recent rainfall, which together decide how favorable a day is for mosquitoes to bite and breed.
- Breeding habitat from ESA WorldCover: the wetland, marsh, open water, and developed cover where mosquitoes breed, measured for each town from 10-meter satellite data.
- The seasonal mosquito calendar and species-specific activity for the floodwater, container, house, swamp, and cattail-marsh mosquitoes that drive nuisance biting and disease.
- West Nile and EEE risk, modeled from habitat and season, with live CDC ArboNET and state health-department surveillance planned to sharpen it.
How often it updates
The risk score is a once-daily figure: it is recomputed every morning from the latest local forecast, so it moves with the weather and the season rather than minute to minute. The underlying habitat and disease data are refreshed as the agencies publish new figures, and each page shows when it was last reviewed.
Who makes it
MosquitoZone is an independent project, built and maintained by a solo developer. It isn't affiliated with any government agency or the data sources it cites. An iOS app with a home-screen widget and daily alerts is in the works; the website stays free.
