Unseasonably Warm, Wet Weather Means More Pests This Fall

If it feels like this September is behaving more like July, you're not imagining it. Between the unusual heat and all the rain we've had lately, Iowa's bugs are just as confused as we are — and that confusion is working in their favor.

Here's what's actually happening: most fall pests take their cue to slow down (or head indoors) from dropping temperatures. When the heat sticks around longer than usual, insects like mosquitoes, ants, and spiders stay active well past their normal window. They keep breeding, keep foraging, and keep multiplying instead of settling into their usual fall retreat.

Then there's the rain. Standing water is basically a maternity ward for mosquitoes, and damp soil drives ants, termites, and other ground-dwelling pests to seek higher, drier ground — which often means your home's foundation, walls, and crawl spaces look pretty appealing right now. Excess moisture also softens wood and stresses trees, both of which invite wood-destroying insects looking for an easy way in.

Put it together and you get a longer breeding season, more pests searching for shelter, and populations that are larger heading into fall than they'd be in a normal year. It's exactly the kind of shift that catches homeowners off guard — because by the time you notice the signs, the bugs have already had weeks of extra time to settle in.

This is really the whole idea behind our seasonal eviction plan. Rather than waiting for a warm, wet stretch like this one to turn into an actual infestation, we adjust our treatments throughout the year to stay ahead of exactly these kinds of shifts. If you've noticed more activity around your home lately, it's worth a quick inspection before things get worse.

Weather like this is also a good reminder to check a few things around your own property: clear out anywhere water can pool (clogged gutters, plant saucers, kiddie pools), trim back vegetation touching your house, and keep an eye on any wood that's stayed damp for more than a day or two. Small steps now go a long way when conditions are already tipped in the bugs' favor.

The bottom line: unusual weather means unusual pest behavior, and reactive treatments just can't keep pace with it. That's why our approach is built around staying a step ahead all year — not just responding once something's already inside. If this stretch of hot, rainy weather has you wondering what's lurking around your home, reach out and we'll take a look before it becomes a bigger problem.
