Earwigs vs. Silverfish: How to Tell the Difference
When you spot a creepy-crawly darting across your bathroom floor or lurking under a stack of laundry, your first thought probably isn’t its species — it’s how to get rid of it. But knowing what pest you’re dealing with is the first step to solving the problem.
Two of the most common culprits that catch homeowners off guard are earwigs and silverfish. While both are small, fast-moving, and often found in damp areas, they’re very different insects with unique habits and behaviors.
In this guide, we’ll help you tell them apart — and more importantly, what to do if you start seeing either one around your home.
What Are Earwigs?
Earwigs are slender, reddish-brown insects with a distinctive feature: pincers (called cerci) at the end of their abdomen. These pincers look intimidating, but earwigs are harmless to humans — they don’t bite or spread disease.
Quick facts about earwigs:
- Length: ¼ to 1 inch
- Color: Reddish-brown to dark brown
- Features: Prominent pincers, short wings (but rarely fly)
- Habitat: Damp, dark areas like mulch beds, under sinks, and basements
- Diet: Decaying organic matter, insects, and sometimes plants
Despite old myths, earwigs don’t crawl into ears or pose a health threat. They’re mostly nuisance pests, though large numbers can be unsettling and may damage plants or household items.
What Are Silverfish?
Silverfish are small, wingless insects named for their shiny, silver-gray color and fish-like movements. Unlike earwigs, they lack pincers — but they do have long antennae and three bristle-like tails at the back of their body.
Quick facts about silverfish:
- Length: ½ to ¾ inch
- Color: Silvery-gray with a metallic sheen
- Features: No wings, long antennae, quick darting motion
- Habitat: Humid spaces like bathrooms, attics, and kitchens
- Diet: Starches, paper, glue, fabric, and dead skin cells
Silverfish are silent destroyers — they chew through books, wallpaper, clothing, and even pantry goods. Over time, they can cause noticeable damage if left unchecked.
Side-by-Side Comparison: Earwigs vs. Silverfish
| Feature | Earwig | Silverfish |
| Size | ¼ to 1 inch | ½ to ¾ inch |
| Color | Reddish-brown to dark | Silvery-gray |
| Shape | Elongated with visible pincers | Flat, teardrop-shaped with bristle-like tails |
| Behavior | Active at night, hides in cracks | Moves quickly in zigzag patterns |
| Diet | Organic matter, insects, plants | Paper, starches, glue, fabrics |
| Risk | Nuisance, minor plant damage | Damage to books, clothing, and wallpaper |
Where Do These Pests Come From?
Both pests thrive in moisture. If you’re seeing earwigs or silverfish inside, it often means there’s a damp environment nearby — and potentially an underlying issue with humidity, leaks, or poor ventilation.
They may enter through:
- Gaps under doors or windows
- Cracks in foundations
- Plumbing access points
- Boxes, newspapers, or secondhand furniture
Once inside, they hide during the day and become active at night — which is often when homeowners spot them in bathrooms, laundry rooms, or kitchens.
Should You Be Concerned?
Neither pest is dangerous in the way that cockroaches or termites can be — but that doesn’t mean you should ignore them.
Earwigs:
- May indicate high moisture levels outside or inside your home
- Can gather in large numbers
- May damage seedlings, flowers, or stored pantry items
Silverfish:
- Can damage books, clothing, wallpaper, and pantry items
- Often go unnoticed until the damage is done
- Thrive in undisturbed areas like attics, basements, or closets
And both pests can be a sign that other moisture-loving insects may follow — such as springtails, centipedes, or even termites.
