Milwaukee stands about 617 feet above sea level on the western shore of Lake Michigan, where the Milwaukee, Menomonee and Kinnickinnic rivers meet. Lake breezes soften the shoreline, but winters stay cold and snowy.
Milwaukee became a city in 1846 when Juneautown and Kilbourntown merged, and it is now the most populous city in Wisconsin, with 577,222 residents in the 2020 census. Wikipedia describes the Milwaukee, Menomonee and Kinnickinnic rivers meeting at the city, with steep bluffs on Lake Michigan beginning about a mile north of downtown.
A local housing form, the Polish flat, stacks two households in one building with separate entrances, so a single pest problem can travel between units. Annual precipitation runs about 34.6 inches with roughly 48.7 inches of snow. January averages near 24 degrees and July about 73, which pushes insects toward heated buildings in fall and stirs ants and ticks in spring.
