Rockford's Pest Control Experts

Pest control on the Rock River

Rockford is the seat of Winnebago County and, with 148,655 people at the 2020 census, the fifth-largest city in Illinois and the biggest outside the Chicago area. It grew on both banks of the Rock River from 1834, and the river, its creeks and the wooded parks along them give mosquitoes, ticks and rodents plenty of places to live close to homes. Older neighborhoods with mature trees and basements add carpenter ants and mice to the list; see mice and rats.

Cold winters, humid summers

Northern Illinois winters are cold, with January highs averaging around 29°F, and July highs average about 84°F. That swing drives the pest year: mice and fall invaders push indoors as the weather cools, while ants, wasps, mosquitoes and ticks peak in the warm, wet months. June is usually Rockford's wettest month. Our fall invaders guide covers the autumn rush.
