Several bugs can look like earwigs at a glance, especially rove beetles, silverfish, cockroach nymphs, some centipedes, and other elongated insects. The fastest way to identify a true earwig is to check the rear of the body. Earwigs have a distinctive pair of forceps-like appendages called cerci at the tip of the abdomen.
That single feature eliminates most look-alikes immediately. Body color is much less useful because plenty of unrelated household insects are brown, reddish brown, or nearly black. Size can overlap too. When we are trying to separate an earwig from another bug, we would start with the rear appendages, then compare body shape, legs, antennae, and where the animal was found.
First, Make Sure You Know What an Earwig Looks Like
A typical European earwig (Forficula auricularia) has an elongated, somewhat flattened body. Adults are commonly around 5/8 inch long, although size varies. They have six legs, medium-length antennae, very short forewings, and a pair of conspicuous cerci at the end of the abdomen.
Those cerci are the best identification shortcut. Adult males generally have stout, strongly curved cerci, while females have slimmer, straighter ones. Young earwigs also have straighter cerci, so do not assume that every earwig must have the dramatic curved pincers seen in many photographs.
Our complete guide to what earwigs look like goes further into their appearance. For this guide, remember the basic combination: six legs, elongated body, antennae, and two obvious appendages projecting from the rear.
Rove Beetles Are One of the Best Earwig Look-Alikes
Of all the bugs that look like earwigs, rove beetles deserve particular attention. Members of the beetle family Staphylinidae are typically slender, and their unusually short wing covers leave much of the abdomen exposed. Many are brown or black and range from about 1/8 to 3/4 inch long, putting some within the same general size range as earwigs.
The exposed abdomen creates much of the confusion. A rove beetle can look less like a conventional beetle and more like a long, flexible insect. Some also raise the tip of the abdomen when disturbed, making the rear end particularly noticeable.
Look at that rear end carefully. Rove beetles do not have the pair of large forceps that identifies an earwig. Their very short wing covers and exposed abdomen are beetle features, not earwig pincers.
This is close enough to justify its own comparison, so our earwig vs. rove beetle guide covers the distinction in greater detail.
Silverfish Can Resemble Earwigs From a Distance
A silverfish has the elongated outline that can make someone think “earwig” before getting a good look. Both can also turn up in dark or damp areas of a house, which makes the confusion more understandable.
Up close, however, the rear end solves this one quickly. Silverfish do not end in earwig-style pincers. Instead, they have three long, tail-like appendages projecting from the rear. Their bodies also taper toward the back and have a distinctive scale-covered appearance.
Silverfish are commonly about 1/4 to 1/2 inch long and occur in cool, damp, dark places inside buildings. That means a quick glimpse in a basement can mislead you, but a clear view usually will not.
Count what is sticking out from the rear. Two forceps-like structures point toward an earwig. Three long filaments point toward a silverfish. We break down the rest of the differences in our earwig vs. silverfish comparison.
Cockroach Nymphs Can Be Mistaken for Earwigs Indoors
A dark cockroach nymph running across a floor can be confused with an earwig because both are flattened insects with six legs and noticeable antennae. Both are also active at night, so the circumstances of a sighting may not immediately settle the identification.
Their shapes differ once you stop looking only at color. Cockroaches have flattened, oval bodies and long antennae. From above, the head of a cockroach is largely concealed by the shield-like pronotum behind it. Nymphs resemble smaller, wingless versions of adults.
An earwig is more elongated, and its rear cerci provide the clearest distinction. A cockroach nymph does not have a matching pair of forceps at the end of its abdomen.
This identification matters beyond curiosity because a cockroach indoors can mean something very different from a wandering earwig. Our earwig vs. cockroach guide is the better place to continue if those are your two candidates.
Centipedes May Be Confused With Earwigs, but Count the Legs
Some centipedes share the long body and quick movement that people associate with earwigs. Stone centipedes can also be reddish brown and live beneath mulch, leaves, loose bark, stones, and similar moist hiding places. Those are exactly the kinds of locations where an earwig might also turn up.
The leg count makes this an easy identification once you can see the animal clearly. Earwigs are insects and therefore have six legs. Centipedes have many more.
For example, house centipedes have 15 pairs of long legs. Stone centipedes also have 15 pairs, although their legs are much shorter and their overall appearance differs substantially from the familiar long-legged house centipede.
So, when a supposed earwig appears to have legs running along much of its body, stop looking for subtle differences. It is not an earwig.
Springtails Can Cause Confusion Around Damp Areas
Springtails make this list for a different reason. They do not closely resemble a full-grown earwig when viewed side by side. However, both can appear around damp areas, and tiny dark springtails are easy to misidentify when all you see is a moving speck near a sink, basement wall, plant pot, or foundation.
Size is your first clue. Springtails are generally only about 1/16 to 1/8 inch long, far smaller than a typical adult European earwig. They may be elongated, but they lack the large rear forceps of an earwig.
Movement gives you an even better clue. Springtails can launch themselves several inches when disturbed using a forked structure underneath the abdomen. Earwigs crawl instead.
If your mystery “earwig” is extremely small and suddenly jumps when you approach it, our earwig vs. springtail guide is a better match for what you found.
Ants Have a Completely Different Waist and Antennae
Some larger brown or dark ants can be mistaken for small earwigs during a quick sighting. Yet the body structure separates them immediately once you know what to check.
Ants have a noticeably constricted waist between the thorax and abdomen. They also have elbowed antennae and one or two nodes in the narrow petiole. Earwigs lack that pinched ant-like waist and have straighter antennae.
The rear end provides the familiar confirmation. Ants do not carry a pair of earwig-style forceps.
An insect following an organized trail with other similar insects is another strong reason to investigate an ant identification rather than assuming earwig. For a direct visual comparison, use our earwig vs. ant guide.
Termites Do Not Have Earwig Pincers
Termites are not especially convincing earwig mimics when examined closely, but indoor insect identification can go wrong quickly when the animal is small or seen for only a few seconds.
Termite workers are pale, wingless insects with broad waists and straight antennae. Subterranean termite workers are associated with their colonies and mud tubes rather than routinely running around exposed rooms. Winged reproductive termites look very different because they have four long wings of approximately equal size.
Those features are fundamentally different from an earwig’s elongated brown body and rear cerci. Termite workers are rarely seen in the open, so the context of the sighting matters too.
We would take a suspected termite identification more seriously than an uncertain earwig because the consequences are different. If those are your two possibilities, use our dedicated earwig vs. termite identification guide rather than treating the insect based on a guess.
Bed Bugs Look Very Different From Earwigs
Bed bugs and earwigs are sometimes compared because both can be found indoors, but visually they are poor matches.
Adult bed bugs have broad, flattened, oval bodies. Earwigs are much more elongated and have the unmistakable forceps at the back. Bed bugs lack those forceps entirely.
Location alone should never decide this identification. An earwig found on a bed does not become a bed bug simply because of where you found it. Likewise, identifying an unknown insect as an earwig just because it is brown can send you in the wrong direction.
If the insect came from bedding, a mattress, or furniture and you are unsure, compare it carefully with our earwig vs. bed bug guide before deciding what you have.
The Rear End Is the Fastest Way to Identify an Earwig
The mistake we would avoid is trying to identify an earwig by brown coloration alone. Brown is simply too common among insects to tell you much.
Instead, get a clear view of the whole animal. Confirm that it has six legs, an elongated body, antennae, and the characteristic pair of forceps at the rear. Then compare any remaining uncertainty against the closest look-alike.
Remember that female and immature earwigs can have relatively straight cerci. The pincers do not need to form the dramatic curved shape of an adult male. They do, however, remain recognizable paired appendages at the end of the abdomen.
If the insect lacks them entirely, reconsider the identification before choosing any control method. Proper identification is the first step in pest management because two similar-looking animals can have completely different habits and require completely different responses.
Other Questions About Bugs That Look Like Earwigs
What bug looks like an earwig but has no pincers?
A rove beetle is one possibility, particularly when the insect is slender, dark, and has a long exposed abdomen. Several other insects can fit a vague description, though, so the entire body should be examined rather than relying on the missing pincers alone.
What looks like an earwig but has lots of legs?
A centipede is a likely candidate. Earwigs have only six legs, while centipedes have many pairs distributed along the body. A house centipede is especially distinctive because its legs are extremely long relative to its body.
What looks like a tiny earwig and jumps?
A springtail is worth checking. Springtails are much smaller than adult earwigs and can jump when disturbed. They are especially common where excess moisture or damp organic material is present.
Can baby earwigs be mistaken for other bugs?
Yes. Earwig nymphs are smaller and generally lighter than adults, and their cerci are relatively straight. However, they still resemble miniature earwigs rather than larvae with a completely different body shape. Our guide to what baby earwigs look like covers their appearance through the immature stages.
What should I do if I still cannot identify the bug?
Capture the insect intact if you can do so safely, or take sharp photographs from directly above and from the side. A local extension service, insect diagnostic laboratory, or pest-management professional can help with specimens that cannot be identified confidently from ordinary household characteristics.
