Why Mosquitoes Stick Around Well Into Fall in Des Moines

In Des Moines, many people expect mosquitoes to fade after summer. But each fall, swarms still show up, and the bites keep coming. Fall mosquito season here lasts longer than most expect. Knowing why helps you protect your home and family.

Warmer central Iowa weather is a big reason. Even as leaves fall, days stay mild enough for mosquitoes to remain active. Standing water in clogged gutters or backyard puddles creates ideal breeding sites into October.

Below, you’ll learn why the season runs long, the risks, and how professional control helps keep your yard comfortable.

How Weather Extends the Fall Mosquito Season in Des Moines

In Des Moines, mosquito season often runs longer than many realize. Mosquito activity slows only after consistent overnight freezes. In many years, central Iowa doesn’t hit those freezing temperatures until late October or even November.

When warm weather lingers, adult mosquitoes keep biting, even after short sunny breaks. Homeowners across Ankeny, Urbandale, and West Des Moines still report bites well after summer. Warm spells let mosquitoes breed longer and feed later in the year.

Standing Water Keeps Fall Mosquitoes Breeding

Even with cooler temps, mosquitoes stick around when water is available. Stagnant water in bird baths, puddles, and clogged gutters creates perfect breeding spots. The City of Des Moines urges residents to dump standing water. Still, many people miss small spots like saucers under flowerpots or toys left outside.

Once female mosquitoes lay eggs, those eggs can survive until conditions are right to hatch. Without regular cleanup, hidden sites can fuel infestations into fall.

The Health Risks of Extended Mosquito Activity

A longer mosquito season is more than a nuisance. Mosquito bites can spread diseases, and Iowa State’s mosquito surveillance program has confirmed the presence of West Nile virus in local mosquito populations. Not every bite is dangerous, but the risk rises when mosquitoes stay active longer.

Heavy mosquito activity also cuts into family time outdoors. In Des Moines and nearby suburbs, late-season infestations often push families indoors during otherwise pleasant weather.

Prevention Tips for Reducing Mosquito Populations in the Fall

Cut mosquito numbers by eliminating their breeding grounds. Start with water. Clear clogged gutters, empty bird baths regularly, and check your yard for puddles after rainfall. Even a cup of stagnant water can hold hundreds of larvae.

Repellents with DEET work well for personal protection. The EPA says DEET repellents are safe when used as directed, so they’re a reliable choice outdoors. Repellents protect skin, but they don’t fix breeding around your home.

For lasting results, consider professional mosquito control. Services like mosquito spraying and larvicide treatments target breeding sites, thereby reducing populations before they become established.
