Omaha spreads across the Missouri River Valley at about 1,060 feet, with creeks such as Papillion Creek draining the metro. Humid summers and about 27 inches of yearly snow keep both spiders and fall insects busy.
Omaha is Nebraska's largest city and the seat of Douglas County, with 486,051 residents counted in 2020. It stands along the Missouri River and is the home of four Fortune 500 headquarters, including Berkshire Hathaway, Union Pacific and Mutual of Omaha. Meatpacking and railroads shaped the older districts, and the Old Market grew from fruit warehouses. Dundee and Benson, Midtown and Elkhorn each add a different building age to the city.
That variety matters for pests. July averages about 76.7 degrees and January about 23.5, so insects that spend the summer outdoors look for heated buildings by fall. Basements and garages in older neighborhoods give spiders quiet corners, trees and wood piles shelter ants, and warm evenings bring Culex mosquitoes, the carriers of West Nile virus in Nebraska.
