How our forecast works
We combine live weather data, seasonal trends, historical pest activity, and local environmental factors to calculate pest risk scores for every city and county in Illinois. Each of the seven pests is scored by its own model, so tick pressure and mosquito pressure in the same city can sit at opposite ends of the scale on the same day. Every score is recalculated every 3 hours — unlike a seasonal calendar or a general weather app, the forecast reacts to the weather Illinois is actually having.
