This is Aurora, Illinois, a Fox River city that grew from Kane County into DuPage, Kendall and Will counties. A river corridor, older wood-frame blocks and fast-growing edges give pests several kinds of habitat inside one city.
Aurora, Illinois counted 180,542 residents in 2020, making it the state's second-largest city. It started in Kane County, and its limits now reach into DuPage, Kendall and Will counties as well. The Fox River divides it into a West Side and an East Side, and the old center sits at Stolp Island. The city stands at roughly 719 feet above sea level. Settlers arrived in 1834, and East and West Aurora merged in 1857.
Winters here are cold and summers are humid. Annual snowfall averages about 27.9 inches, precipitation runs near 40 inches, and the average July high is 83.5 degrees. A July 1996 storm dropped 16.94 inches of rain in 24 hours, an Illinois record. Older homes, including the mail-order houses around New York Street, mean wood and moisture, while river and rain fuel mosquitoes.
