Earwigs in Colorado: What You Need to Know About These Pincher Bugs

If you’ve spent time outdoors in Colorado, especially during the warmer months, you’ve likely come across earwigs in Colorado. Also called pincher bugs, these insects are often spotted in yards, gardens, and even inside homes. Their distinct pincers give them an intimidating look, leading many to wonder if they are dangerous or harmful.

For homeowners, the concern isn’t just about their creepy appearance—it’s about why they suddenly appear indoors. Colorado’s dry climate influences pest behaviors, and earwigs in Colorado are no exception. When conditions become too dry, they look for moist, dark places to survive, which is why they sometimes invade homes.

At OBEX, we believe that understanding earwigs in Colorado is the first step in keeping them under control. Let’s take a deep dive into these insects — what attracts them, whether they pose a real threat, and how to effectively manage them.

Earwigs have a distinctive appearance, making them easy to identify. They are typically ½ to 1 inch long, with a reddish-brown or dark brown exoskeleton. Their bodies are elongated and slightly flattened, allowing them to squeeze into tight spaces. The most recognizable feature of earwigs in Colorado is the pair of forceps-like pincersextending from the abdomen.

These pincers, known as cerci, have different shapes depending on the gender of the earwig:

• Males have more curved and thicker pincers, which they use for defense and mating battles.
• Females have straighter, thinner pincers, used mostly for self-protection.

Some species of earwigs in Colorado have wings, though they rarely fly. Instead, they move quickly along surfaces and prefer to hide in dark, damp environments. Their flattened body structure allows them to wedge into cracks and crevices, making them difficult to spot until they become a problem.

The biggest concern many people have is whether earwigs in Colorado bite. The short answer? No, they do not bite humans.

Despite their menacing appearance, their pincers are not strong enough to pierce human skin. If handled roughly, an earwig might attempt to pinch, but it’s typically harmless. Unlike spiders or ants, earwigs in Colorado do not have venom and do not spread diseases.

While they are harmless to humans and pets, they can become a nuisance, especially when they invade homes in large numbers. If you’re noticing earwigs in Colorado homes, it’s usually a sign that your property has moisture issues attracting them indoors.

This European earwig in Colorado uses its pincers for defense but is harmless. Though beneficial outdoors, earwigs in Colorado often invade homes seeking moisture.

Unlike many insects that invade homes for food, earwigs in Colorado typically enter homes searching for moisture. The state’s semi-arid climate means these insects often seek damp areas to survive.

Common reasons earwigs in Colorado enter homes include:

• Dry outdoor conditions pushing them inside
• High humidity in basements, crawl spaces, and bathrooms
• Potted plants with damp soil
• Entry through cracks in doors, windows, and vents

Because earwigs in Colorado are most active at night, homeowners often don’t realize they have an infestation until they spot them scurrying away from dark corners when turning on a light.

Earwigs in Colorado are omnivorous , meaning they consume both plant material and insects. Their diet includes:

• Decaying organic matter (leaves, wood, and mulch)
• Fungi and algae, often found in damp environments
• Small insects such as aphids and mites
• Fruits, vegetables, and flowers

Because they feed on other insects, small populations of earwigs in Colorado gardens can actually be beneficial. However, when their numbers increase, they may begin damaging garden plants and soft fruits by chewing holes in leaves and flowers.

One of the most persistent myths about earwigs in Colorado is that they crawl into human ears while people sleep. This is completely false.

The name earwig originates from an old European myth claiming these insects burrow into ears and lay eggs in the brain. In reality, earwigs in Colorado have no interest in human ears. They prefer damp, hidden spaces outdoors, such as mulch beds, woodpiles, and under potted plants.

If you are noticing earwigs in Colorado homes, there are several effective ways to reduce their numbers. The most important step is eliminating excess moisture, as this is the main reason they seek shelter indoors.
