Why Not Spray?

For more than 25 years, a city truck fogged Des Moines neighborhoods for mosquitoes every summer. That’s over. The honest answer to “why not spray?” has two parts: the city already decided to stop — and spraying was never the part that actually protected your yard.

What the city changed

In 2025, Des Moines cut citywide neighborhood spraying for the first time in more than 25 years, saving roughly $300,000. The fog trucks stopped, the traps and counters that tracked local mosquito numbers were pulled, and the city’s mosquito-reporting hotline was shut off. In September 2026, the city council approved a budget that ends what remained of its mosquito treatment contract.

  • Neighborhood fog-truck spraying — gone
  • City mosquito trapping and population counts — gone
  • The city mosquito-report hotline — gone

The city’s advice now is essentially what this site is built around: empty standing water, keep grass cut, screen your windows, and use repellent.

Spraying was never the hero

Fogging kills the adult mosquitoes that happen to be flying when the truck passes. It doesn’t touch the larvae growing in standing water, and a fresh generation is back within days. Even the city said the benefit often didn’t justify the cost. The thing that actually shrinks the mosquito population works upstream: emptying the water where they breed before they ever hatch. It’s cheaper, it’s spray-free, and it’s something you can do on your own block.

So are we in trouble?

Not doom — but not nothing, either. West Nile virus is a normal part of Iowa summers, and 2025 brought the highest West Nile activity in Iowa mosquitoes in more than two decades. Most people who get infected never feel it — about four in five have no symptoms — but the risk is real enough to take basic precautions, especially at dawn and dusk. The point isn’t fear. It’s that the safety net came off in a year the risk was climbing, so it’s on neighbors now.

One yard helps. A block wins.

A single tipped-over bucket in your yard makes a small dent. Ten neighbors doing the same thing on one block changes the mosquito math for everyone — including the folks who can’t get out to do it themselves. That’s the whole idea behind Skeeter Defeater DSM: make it easy, make it neighborly, and let each block defend itself.
