Are Earwigs Dangerous? A Helpful Guide for Homeowners in Chico, CA

As a homeowner in Chico, CA, you might have encountered the occasional earwig in your garden or even inside your home. While these insects are often alarming due to their distinctive pincers, it’s important to understand whether they pose any actual danger. Here’s a closer look at earwigs, their behavior, and what you should know to protect your home.
What Are Earwigs?
Earwigs are small, nocturnal insects commonly found in damp, shaded areas. They’re easily identifiable by their slender, elongated bodies and the pincers (or cerci) on the back end of their abdomen. These pincers are often the reason people fear them, but despite their intimidating appearance, earwigs are not dangerous to humans.
Are Earwigs Poisonous?
No, earwigs are not poisonous. They do not possess venom or toxins that can harm humans or pets. While the sight of their pincers can be off-putting, they do not pose any danger in terms of poisoning. If an earwig pinches you, it’s a defense mechanism, but the pinch is harmless.
Can Earwigs Cause Damage?
Earwigs themselves do not cause direct harm to humans or pets. However, they can cause damage to plants, especially in gardens or landscaping. Earwigs are known to feed on decaying organic matter, but they can also munch on the leaves, flowers, and fruits of various plants. In large numbers, earwigs can become a pest in gardens, damaging crops, ornamental plants, and flowers. In homes, they are more of a nuisance than a destructive pest, as they seek moisture and shelter, but they are not known to damage structures or furniture.
If earwigs are causing significant damage to your garden or becoming a frequent indoor visitor, it’s a good idea to take preventive measures or consult with a pest control professional to manage the situation.
Do Earwigs Bite?
Earwigs are not known to bite humans. While they do have pincers, they are primarily used for defense and capturing prey, not for attacking people. If you accidentally handle an earwig, it may use its pincers to pinch as a means of self-defense, but the pinch is typically not harmful or painful. It might cause mild discomfort but nothing more than a temporary nuisance.
Do Earwigs Carry Diseases?
No, earwigs do not carry diseases that affect humans. They are not known to transmit any pathogens or viruses. While they can be a nuisance, they don’t pose a significant health risk.
What Do Earwigs Look Like?
Earwigs are easily identifiable by their long, slender bodies and distinctive pincers, known as cerci, at the rear end of their abdomen. These pincers are curved and give earwigs a somewhat intimidating appearance, but they are harmless to humans. Adult earwigs typically range in size from 1/2 to 1 inch long and can be either brown or dark reddish-brown in color. Their wings are folded underneath their hard outer shell, and while some species have wings, they are not very commonly seen flying.
What Is the Lifespan of an Earwig?
Earwigs generally live for about one year. They spend the majority of their life outdoors, but as the seasons change and weather conditions shift, they may seek shelter indoors during colder months. Their lifespan can be shortened or lengthened depending on environmental factors, food availability, and predation.
Where Do Earwigs Live?
Earwigs are typically found in damp, dark areas, both outdoors and indoors. Outdoors, they can be found in garden soil, under rocks, leaves, mulch, or in compost piles. Indoors, they tend to hide in places with high humidity, such as basements, bathrooms, kitchens, and crawl spaces. They often seek shelter at night and are nocturnal creatures, making them more active when it's dark.
Why Are Earwigs In My House?
Earwigs might enter your home in search of food or moisture, especially during dry or hot weather. If your yard or garden provides ample food and moisture, they may venture inside through cracks and gaps in windows, doors, or walls. Once indoors, they’ll typically stay in humid areas, such as bathrooms, kitchens, or basements, and are attracted to decaying organic matter or food sources.

Are Earwigs Dangerous to Humans?
The good news is that earwigs are not dangerous to humans—they do not bite, sting, or spread diseases. While their pincers may look menacing, they are mainly used for defense and capturing prey. Earwigs may pinch if handled, but their pincers are not strong enough to cause harm. In rare instances, a pinch can cause mild discomfort, but it’s nothing more than a small nuisance.
Earwigs and Your Home
While earwigs are not harmful to people, they can be a nuisance in your home. These insects are attracted to moist environments and can sometimes be found indoors in search of food or shelter. If you have areas in your home with high humidity—such as bathrooms, basements, or kitchens—you may notice them inside. Earwigs also tend to gravitate toward decaying organic matter, so cluttered areas or poorly maintained gardens are also attractive to them.
How Can You Prevent Earwigs in Your Home?
If you live in Chico, CA, and are dealing with earwigs in your home, here are some helpful tips to reduce their presence:
- Seal Entry Points: Earwigs often enter homes through small cracks or gaps. Ensure that doors and windows are sealed properly, and inspect your home for any openings that could allow pests inside.
- Reduce Moisture: Earwigs are attracted to moisture, so keep areas like bathrooms, kitchens, and basements as dry as possible. Use dehumidifiers or exhaust fans in these areas to help reduce humidity.
- Trim Overgrown Vegetation: Earwigs like to hide in piles of leaves, grass, and other garden debris. Keep your yard tidy and trim back any overgrown vegetation close to your home’s foundation to eliminate their hiding spots.
- Clean Your Home Regularly: Keep your home clean by vacuuming up any debris and clutter. Pay special attention to areas that might harbor food scraps or organic matter, which can attract pests.
- Use Traps: Simple earwig traps, like rolled-up newspapers or damp cardboard, can attract earwigs and give you a way to remove them from your home. Simply place the traps in areas where you've seen earwigs and dispose of them as needed.
