Why Flies Are So Bad in Oklahoma This Year

Every spring in western Oklahoma, there is a moment when you step outside and immediately question your life choices. It usually happens the first time a fly bounces off your forehead like it paid admission to be there.

If you haven’t noticed the flies yet, congratulations. You’re living in one of the tiny fly-free bubbles that somehow exist every year. The rest of the state is currently dealing with what feels like a full-scale fly population boom.

Flies are normal in Oklahoma. Always have been. Towns that live close to cattle, feedlots, or livestock auctions basically treat them like background noise. Hollis knows the deal. That is just everyday life out there.

What's different this year is how widespread the flies are. They're swarming in places that usually don't have more than just an annoying average at the cookout.

Why are flies everywhere right now?

The short answer is, agriculture. But even then, it's only part of the larger story... the weather.

This whole chain reaction started with that incredibly warm winter. I think the biggest cold stretch was only a few days below freezing once, maybe twice in the northern corners of the state. Other than those handful of days, it was a perpetual fall/spring across the Sooner State.

Cold weather puts insects into a sort of reset mode. And since winter never really showed up, that reset never happened, giving flies a head start this year.

The insects have had a full calendar year of ideal breeding conditions.

You probably noticed mosquitoes exploding early this year. I got eaten up in January while fishing. That was the first clue. Flies tend to follow the same playbook on a slightly delayed schedule.

What comes next?

When flying insects boom, the predators that eat them get a boost too. That means spider populations usually climb right behind mosquito and fly spikes. More food means the environment can support more hunters.

So if webs start appearing in every corner of your porch and garage later this summer, that is not random. It is the ecosystem cashing in on a buffet.

If you want to keep as much of this wildlife as possible outside your house, this is the moment to do a quick home check.

Look at doors and windows first. Weatherstripping, seals, and tiny gaps you stopped noticing years ago. Small openings turn into insect highways during seasons like this.

Walk the yard and dump standing water anywhere you find it. Buckets, toys, lids, tarps, anything that can hold rain for a few days becomes a breeding site. You do not have to become obsessive about planters, but the obvious water collectors matter more than most people realize.
