Welcome to your weekly Illinois bug bites forecast for October 12, 2026! Overall, we’re looking at a moderate risk this week, largely influenced by the significantly wetter conditions Illinois has experienced recently, with 194mm of rain compared to just 46mm this time last year. This unusual rainfall has kept standing water and prime breeding grounds much more widespread than typically seen in mid-October, meaning some pesky insects are still very much in play.

In Northwest Illinois, expect cooler temperatures with some lingering dampness from recent showers. Mosquito activity will be declining but still present in sheltered, wet areas, while ticks remain a concern in wooded and grassy regions as they seek their last meals before winter.

Moving to Northeast Illinois, including the greater Chicago area, conditions will be similar to the northwest with a crisp autumn feel. Mosquitoes will be less of a nuisance, but don’t let your guard down for ticks, especially if you’re enjoying the last beautiful days in parks or nature preserves.

Southwest Illinois will see slightly milder temperatures compared to the northern parts of the state, but the abundant moisture from recent weeks means you should still be mindful of lingering mosquito populations around standing water. Additionally, the mild weather could keep some late-season biting flies active.

Finally, in Southeast Illinois, enjoy the pleasant autumn weather, but remember that the extended wet period has created ample opportunities for various biting insects. While mosquitoes are on the decline, ticks and some late-season gnats might still be out and about, so remember that Just Bite Me temporary bug bite relief is available at retailers across Illinois.
