Why Wasps Are Showing Up Early in Colorado

(And What to Do About It)

If it feels like wasps are showing up earlier than usual this year… you’re not imagining it.

Unseasonably warm spring weather across Colorado is causing flowers to bloom, trees to bud, and the bugs to come out and lay. The warm weather is also waking wintering queen wasps sooner than normal. Instead of waiting until late spring, they’re already out scouting nesting sites, building new colonies, and settling in around homes and businesses.

That means one thing: wasp season is starting earlier, and potentially lasting longer.

Why Early Spring Weather Brings More Wasps

In a typical year, wasps stay dormant through the colder months. But when temperatures spike early, queen wasps emerge ahead of schedule and begin building nests right away.

The earlier they start, the bigger their colonies can grow by summer.

That’s why you might already be seeing:

  • Wasps flying near your roofline or deck
  • Small starter nests under eaves
  • Increased activity around trash cans or outdoor spaces

Catching this early can make a big difference. Again, since they are starting early, we have the potential to see larger colonies than normal once summer actually hits.

DIY Tips to Keep Wasps Away

Before things get out of hand, there are a few simple steps you can take to reduce your chances of a wasp problem:

  • Seal up entry points – Check for gaps around siding, vents, and rooflines
  • Keep trash tightly closed – Wasps love food scraps and sugary residue
  • Clean up outdoor eating areas – Especially patios and grills
  • Knock down very small nests early – Only if they’re easily accessible and you can do so safely
  • Limit standing water – Wasps need water just like any other pest

These steps can help, but they’re most effective early in the season, before colonies grow.

When DIY Isn’t Enough

Here’s the reality: once a nest starts growing, it becomes much harder, and more dangerous, to handle on your own.

Wasps are highly territorial. Disturbing a nest can trigger aggressive behavior, and unlike bees, they can sting multiple times. Plus, when a wasp is injured or killed, it releases a pheromone alerting other wasps there is danger. This could mean a full all attack against you, your kids, or pets.

On top of that, many nests are located:

  • High up under roof eaves
  • Inside wall voids
  • In trees or hard-to-reach areas

That often means ladders… which adds another layer of risk.

At that point, it’s not just about getting rid of wasps, it’s about avoiding stings and keeping your family safe.
