You wake up. There is a scratching sound. Not outside your window or in the hallway, but inside your head. It’s localized, frantic, and honestly, a little bit terrifying. Your first thought is probably the one thing everyone "knows" about these insects: that they crawl into your brain to lay eggs.
Relax. They don't do that.
Finding an earwig in the ear is a genuine medical event, but the folklore surrounding it is mostly nonsense. The name "earwig" actually comes from the Old English ear-wicga, which literally translates to "ear wiggler." For centuries, people have been convinced these pincher-tailed bugs have a biological vendetta against human hearing. They don't. They just like tight, dark, moist spaces. Your ear canal happens to fit the description of a luxury apartment for a bug that spends its life hiding under damp logs.
Why Do They Even Go In There?
Earwigs are thigmotactic. That’s a fancy way of saying they like to be touched by their surroundings on all sides. When you’re sleeping on a camping trip or in a basement bedroom, an earwig is just looking for a crevice. It’s dark. It’s warm. It’s humid. It feels safe to them.
They aren't parasites. They aren't looking for a host. You are just a warm, fleshy cave.

Most cases of an earwig in the ear happen because the insect stumbled in and then realized it couldn't easily turn around. Because their bodies are long and their legs move in a specific way, backing out is a nightmare for them. So they scramble. They scratch. That scratching sound? It’s not them eating your eardrum. It’s just their little legs vibrating against your tympanic membrane. It sounds like a jackhammer because the sound is being amplified by your own anatomy.
Debunking the Brain-Eater Myth
Let’s get the scary stuff out of the way immediately. An earwig cannot reach your brain. It is physically impossible. The ear canal ends at the eardrum (the tympanic membrane), which is a tough, fibrous barrier. Unless you have a pre-existing perforated eardrum, the bug is stuck in the outer ear canal.
And the egg-laying? Total myth. Earwigs are actually surprisingly good mothers in the insect world—they stay with their eggs and guard them against predators. But they lay those eggs in soil, deep underground where it's cool and damp. Your ear is far too chaotic and warm for their reproductive needs.
What It Actually Feels Like
People describe the sensation of an earwig in the ear as a "rushing" or "scrubbing" sound. Because the insect has cerci (those pincers at the back), you might feel a sharp pinch. It hurts, but it’s rarely dangerous. The real danger usually comes from the human panicking and trying to dig it out with a Q-tip.

Don't do that. Seriously.
When you stick a cotton swab or a finger in there, you do two things. First, you likely squash the bug, which releases fluids that can cause irritation or infection. Second, you might push the insect deeper, potentially rupturing your eardrum with the bug's own body. It's a mess.
How to Get It Out Safely
If you’re sure there’s a live earwig in the ear, you have a few options before you sprint to the ER.
- Gravity first. Tilt your head so the affected ear faces the ground. Shake your head gently. Sometimes, if the bug hasn't wedged itself in, it will just crawl out.
- The Mineral Oil Trick. This is the gold standard for home removal. Use room-temperature mineral oil, baby oil, or even olive oil. Lean your head over and drop a little oil into the canal. This usually suffocates the insect and, more importantly, stops it from scratching. Once the movement stops, the "jackhammer" sound stops. You can then gently flush it out with warm water using a bulb syringe.
- Avoid water if it’s alive. While oil is great, plain water can sometimes make the insect panic. Insects can also swell slightly when exposed to certain liquids, making them even harder to remove.
If the insect doesn't come out easily, or if you start experiencing intense pain, dizziness, or bleeding, go to an urgent care clinic. Doctors have specialized tools—long, skinny forceps and suction devices—that can grab a stubborn earwig in seconds.

Real Risks and Complications
While the "brain eating" stuff is fake, there are actual medical concerns. The most common is otitis externa, better known as swimmer's ear. If the earwig scratches the delicate skin of the ear canal, bacteria can move in. You’ll know this is happening if your ear starts to throb or leak fluid a day or two after the "incident."
Occasionally, the pincers can leave small marks. Earwigs use these for defense and mating, but they don't have venom glands. It’s a mechanical pinch, nothing more. The primary risk is always secondary infection or trauma caused by the person trying to "rescue" themselves with a pair of tweezers or a bobby pin.
Preventing the Midnight Scramble
You shouldn't live in fear of the "ear wiggler," but if you live in an area prone to them—like the Pacific Northwest or damp parts of the UK—a few tweaks to your environment help.
- Move the woodpile. Earwigs love rotting wood and mulch. If your firewood is stacked against the house, you're inviting them in.
- Fix the seals. Check the weather stripping on your doors.
- Dehumidify. They hate dry air. If your bedroom is in a basement, run a dehumidifier.
- Earplugs. If you're camping and the thought of an earwig in the ear is keeping you awake, just wear foam earplugs. It’s the only 100% effective physical barrier.
Practical Next Steps
If you suspect something is currently moving in your ear, stop reaching for the Q-tips. Check your peripheral vision or have a friend shine a flashlight near (not directly into) the ear. Sometimes the light lures them out. If that fails, the oil method mentioned above is your best bet for immediate relief. Once the bug is out, keep the ear dry for 24 hours. If you feel any lingering "fullness" or hearing loss, see an ENT specialist to ensure no legs or antennae were left behind to cause an inflammatory reaction.
Most people who experience this come away with a great story and zero permanent damage. It’s a temporary, albeit gross, inconvenience of living in a world full of tiny, confused explorers.
