What Are European Fire Ants?

European fire ants, also known as Myrmica rubra, are an invasive species originally from Northern Europe and parts of Asia. Unlike the fire ants commonly found in the southern U.S., these pests thrive in cooler, moist climates—making Bellevue’s environment ideal for them to spread.


They were first spotted in the Seattle area near Lake Washington, and since then, sightings have increased throughout the region. These ants don’t build large, noticeable mounds. Instead, they nest in hidden spots like under rocks, logs, leaf litter, and even potted plants. That makes them tough to spot—until someone gets stung.

How to Identify European Fire Ants

At first glance, you might confuse European fire ants with regular red ants. But a closer look reveals key differences.

Worker ants are about 1/5 to 1/4 inch long and reddish-brown in color. Their bodies have two backward-pointing spines on the middle section and a distinctly segmented waist. The queen is slightly larger, close to 1/2 inch, and looks similar in color and shape.



Unlike many native ant species in Bellevue, these ants are quick to swarm when disturbed. Their sting can cause painful, itchy welts that last for hours, and they often sting multiple times.

Where You’re Likely to Find Them in Bellevue

European fire ants love moisture. That means Bellevue’s gardens, shaded lawns, parks, and even backyard flower beds are perfect habitats. They prefer spots with high humidity and cover, like under yard debris, mulch, or overgrown vegetation.


You might not even know they’re there until you unknowingly disturb a colony. These ants don’t create visible mounds. Instead, they camouflage their nests in shaded, damp places, making detection tricky until someone accidentally brushes against them or steps nearby.

Why They’re a Problem for Bellevue Residents

Aside from the painful stings, European fire ants can make it difficult to enjoy your outdoor space. They tend to build dense colonies and often have multiple queens, allowing their population to grow rapidly.



But the threat doesn’t stop at physical discomfort. These ants also displace native ant species and disrupt the local ecosystem. They protect aphids and other insects that damage plants and compete with local pollinators for nectar. Over time, this can lead to an increase in harmful pests and a decline in beneficial insects like bees and butterflies.



How They Spread

One of the biggest challenges with European fire ants is how easily they spread. They often hitch rides in soil, potted plants, mulch, and even gardening tools. In many cases, new infestations start because someone unknowingly transported contaminated materials.


In Bellevue, where gardening is a popular pastime and landscaping often includes mulch or wood chips, the chances of unintentional spread are high. Once introduced, colonies can fragment and spread to nearby areas, forming satellite nests that work together to sustain the population.

Tips to Prevent and Control Infestations


Controlling European fire ants in Bellevue requires a proactive and strategic approach. Here are some ways to reduce the risk of infestation:


  • Inspect soil and plants before bringing them home. If you're purchasing potted plants or soil, check for signs of ant activity first.

  • Keep your yard dry when possible. These ants thrive in moisture, so limit watering and avoid overwatering lawns and flower beds.

  • Remove yard debris regularly. Clear out logs, leaf piles, and old mulch that could shelter ants.

  • Seal cracks and entry points around your home’s foundation and exterior walls to keep ants from getting inside.

  • Avoid creating pest-friendly environments. Clean up fallen fruit, compost, or food waste that might attract ants or the aphids they protect.

For ongoing problems, using targeted bait or barrier treatments may help, but working closely with pest control specialists in Bellevue is often the most effective solution.
