Cricket Infestations in West Central Iowa: Late-Summer Prevention Guide
If it feels like the chirping outside your window has cranked up in the last few weeks, you're not imagining it. Late August is peak season for crickets here in West Central Iowa, and this year's warm, humid stretch has been ideal breeding conditions for them. That means bigger populations right now — and a bigger chance some of them decide your house looks like a nice place to ride out the coming cooler nights.
Why Crickets Show Up Now
Crickets are most active in late summer and early fall as they finish out their breeding cycle before the first frost. As overnight temperatures start to dip, they instinctively seek out warmth — and gaps around your foundation, garage door, or window screens are an easy way in. Porch lights and outdoor fixtures don't help either; crickets are drawn to light, which is why you'll often find them clustered near entry doors after dark.
A few crickets chirping in the yard is just late-summer background noise. But once they get inside, they can chew on fabric, cardboard, and even wallpaper paste, and a cricket infestation in a basement or crawl space can get loud fast — literally.
Simple Ways to Keep Them Outside
Seal gaps around foundation cracks, utility lines, and window/door frames
Swap bright white porch lights for yellow "bug" bulbs, which are less attractive to crickets
Keep firewood, mulch, and dense vegetation a few feet away from your foundation
Reduce outdoor lighting overnight where you can, or aim fixtures away from entry points
If you're already hearing them indoors — especially in a basement, crawl space, or closet — that's usually a sign they've found a way in that's worth tracking down before fall brings the rest of the overwintering crowd (think stink bugs and boxelder bugs) looking for the same gaps.
