Pest Control in Oak Brook, IL

Oak Brook has four distinct seasons. July highs average about 84 degrees, and January lows average around 15, so winter is the harsher swing. The area receives about 40 inches of precipitation in a typical year, and May is usually the wettest month at roughly 4.8 inches. Around 17 days a year reach 90 degrees or higher. Those figures are 1991-2020 NOAA climate normals from a nearby weather station, so treat them as a guide, not a forecast.

A wet May sets up mosquitoes. Any spot that holds water for a few days, such as clogged gutters, plant saucers, bird baths and low patches of lawn, can turn into a nursery. Around ponds and shaded parkland, mosquito control becomes more worthwhile once the weather warms. The same spring moisture softens wood and mulch that termites and carpenter ants favor, so check foundation edges and deck posts while the ground is soft.

With about 144 freezing nights, fall is the season to act. Walk the outside of the house before the first hard frost, looking for gaps at doors, utility lines and the garage. In winter, listen for scratching in the attic or wall voids, since rodents stay active even when the yard is quiet. Come spring, a fresh look at the house helps you see what the cold months left behind.
