Finding earwigs in outdoor chair can be frustrating, especially when they seem to choose your seat while ignoring every other chair on the patio. If you’ve ever wondered why this happens, you’re not alone. One of our readers recently asked why earwigs kept showing up in his chair but never in his wife’s identical chair.
The good news is that earwigs usually aren’t attracted to people. They’re attracted to specific conditions that make one chair a better hiding place than another. In this guide, you’ll learn why earwigs favor certain outdoor chairs, how to figure out what’s really attracting them, and the best ways to keep them from coming back.

Earwigs in Outdoor Chair: Why Do They Keep Showing Up?
At first glance, it can feel like earwigs have picked you as their favorite person. After all, if two chairs look exactly the same, why would they keep appearing in only one?
The answer is surprisingly simple: earwigs choose environments, not people.
During the day, earwigs spend most of their time hiding from sunlight and dry air. They look for places that are:
- Cool
- Dark
- Slightly damp
- Protected from predators
An outdoor chair can provide exactly those conditions. The underside of the seat, small gaps in the frame, folds in mesh fabric, and even screw holes create tiny shelters that are perfect for resting until nightfall.
What often surprises homeowners is how sensitive earwigs are to small environmental differences. Two chairs sitting only a few feet apart may experience different amounts of shade, airflow, or moisture.
For example:
- One chair may stay shaded longer during the afternoon.
- Morning dew may evaporate more slowly on one side of the deck.
- Nearby plants can increase humidity around a single chair.
- One chair may simply have a better hiding space inside its frame.
Tiny differences that humans barely notice can make a big difference to an earwig.
Are earwigs trying to get on you?
Fortunately, no.
Unlike mosquitoes or ticks, earwigs are not looking for a host. If you find one crawling across your chair, it most likely wandered there during the night and stayed because it found a safe place to hide before sunrise.
If you accidentally disturb one while sitting down, it may run quickly across the chair, making it seem like it came after you. In reality, it’s trying to escape.
Top 8 Reasons Earwigs Choose One Outdoor Chair Over Another
Understanding why one chair attracts earwigs is the first step toward solving the problem.
Slightly More Shade Throughout the Day
Shade keeps temperatures lower and helps retain moisture.
Even if both chairs are on the same deck, one might receive an extra hour of afternoon shade from:
- The house
- Deck railings
- Trees
- Patio umbrellas
That small temperature difference can make one chair much more appealing.
Morning Dew or Trapped Moisture
Earwigs lose moisture easily and prefer humid environments.
Mesh seating, canvas fabric, or textured surfaces sometimes hold moisture longer after rain or heavy morning dew.
Check whether your chair remains damp longer than the other one.
Tiny Gaps in Mesh or Chair Frame
Earwigs don’t need much space.
They can squeeze into:
- Hollow aluminum tubing
- Folded mesh edges
- Bolt openings
- Loose joints
- Fabric seams
Those narrow spaces provide ideal daytime shelter.
The Chair Is Closer to Plants or Mulch
Earwigs often spend the night feeding in gardens before searching for shelter at sunrise.
If your chair is even slightly closer to:
- Flower beds
- Mulch
- Potted plants
- Dense shrubs
- Ground cover
it naturally becomes the first hiding place they encounter.
Nearby Cracks in the Deck
Wooden decks often develop small gaps between boards.
Those cracks provide cool, protected spaces where earwigs hide during the day.
A chair sitting directly above these hiding spots may simply be more convenient.
Food Debris or Organic Matter
Although earwigs don’t usually seek human food first, they will feed on decaying organic material.
Tiny bits of food, fallen leaves, pollen, or bird droppings around one chair can encourage more insect activity overall.
Regular cleaning helps eliminate these attractions.
Less Disturbance During the Day
Earwigs like quiet hiding places.
Perhaps your wife’s chair gets moved more often, receives direct sunlight, or is used earlier in the day.
Even small disturbances can encourage earwigs to relocate elsewhere.
Pure Chance That Became a Habit
Sometimes there’s no obvious explanation.
One earwig discovers a good hiding spot, others eventually follow, and the chair becomes a reliable daytime shelter.
Nature isn’t always perfectly logical.
Quick Summary: Most Common Causes
| Possible Cause | How Likely? | Easy to Check? |
| More shade | High | Yes |
| More moisture | High | Yes |
| Better hiding spaces | High | Yes |
| Closer to plants | Medium | Yes |
| Deck cracks underneath | Medium | Yes |
| Food residue | Low to Medium | Yes |
| Less daily disturbance | Medium | Yes |
| Random preference | Low | No |
Are Earwigs Attracted to Humans, Sweat, Blood Type, or Vitamins?
One of the most common questions people ask is whether earwigs are attracted to certain people.
This idea often comes from comparisons with mosquitoes, which are known to prefer some individuals over others due to body chemistry, carbon dioxide, and other factors.
Earwigs behave very differently.
Do earwigs bite or feed on people?
No.
Earwigs are scavengers and occasional plant feeders. Their diet mainly includes:
- Decaying plant material
- Small insects
- Aphids
- Fungus
- Organic debris
Although they have forceps-like pincers on their abdomen, they’re used primarily for defense, catching prey, and mating—not feeding on humans.
Does blood type matter?
There is no scientific evidence that earwigs are attracted to any blood type.
Whether you’re Type A, B, AB, or O doesn’t make your outdoor chair more attractive.
Mosquitoes rely on body odors, heat, and carbon dioxide to locate hosts.
Earwigs simply don’t.
Can sweat or body odor attract earwigs?
Current evidence suggests no.
Sweat, skin oils, perfume, or deodorant don’t appear to influence earwig behavior in any meaningful way.
If earwigs keep appearing on your chair, it’s almost always because of the chair’s environment rather than anything about you.
What about B100 vitamins?
This is another common theory.
Some people believe vitamin B supplements repel mosquitoes, although research has found little consistent evidence supporting that claim.
When it comes to earwigs, there’s no evidence that B100 vitamins attract or repel them.
Your supplement routine is almost certainly unrelated to why earwigs are choosing one outdoor chair over another.
The biggest takeaway: If you’re finding earwigs only on your chair, don’t assume they’re interested in you. They’re much more likely responding to shade, moisture, shelter, or location than to anything about your body.
How to Tell Whether It’s the Chair or the Location
If you have two nearly identical chairs, the easiest way to solve the mystery is to run a few simple tests. You don’t need any special equipment—just a little observation over several days.
The goal is to determine whether the earwigs are attracted to the chair itself or where the chair is sitting.
Swap the Chairs
This is the quickest and most revealing test.
Move your chair to your wife’s spot and place hers where yours normally sits. Check both chairs each morning for three to five days.
Here’s what the results can tell you:
- Earwigs stay with the location: The environment is the problem.
- Earwigs stay with the same chair: The chair has better hiding places.
- Earwigs disappear altogether: The disturbance from moving the chairs may have disrupted their routine.
Move the Chair to Another Part of the Deck
If possible, place the chair several feet away from its original location.
Pay attention to whether it’s now receiving:
- More sunlight
- Better airflow
- Less humidity
- Greater distance from nearby plants
A simple move can sometimes solve the problem without any pesticides.
Inspect the Underside Carefully
Flip the chair over and examine every hidden area.
Look for:
- Hollow aluminum tubing
- Loose mesh fabric
- Drain holes
- Screw openings
- Dirt trapped inside the frame
- Spider webs or insect debris
A flashlight can reveal hiding spots that are easy to miss during daylight.
Compare After Rain and Dry Weather
Weather often changes earwig activity.
Keep notes for about a week.
| Condition | What You Might Notice |
| After rain | More earwigs hiding in the chair |
| Heavy morning dew | Increased activity |
| Hot, dry afternoons | Fewer visible earwigs |
| Several dry days | Reduced numbers overall |
If earwigs appear mainly after wet weather, moisture is likely the biggest factor.
Watch Where They Go
If you happen to see an earwig at sunrise or shortly afterward, avoid disturbing it immediately.
Instead, watch where it heads.
It may crawl:
- Into the chair frame
- Under the deck boards
- Into nearby mulch
- Beneath a planter
- Into cracks between wooden boards
Following its path often reveals the actual hiding place.
Quick Checklist
Before assuming the chair is “cursed,” ask yourself:
- ✔ Does this chair stay wetter longer?
- ✔ Is it closer to landscaping?
- ✔ Does it receive more shade?
- ✔ Does it have extra hiding spaces?
- ✔ Have I tried swapping the chairs?
Answering these questions usually points to the real cause.
How to Get Rid of Earwigs in an Outdoor Chair
Once you’ve figured out why earwigs are choosing your chair, it’s time to make that spot less inviting.
Fortunately, most outdoor chair problems can be solved with simple maintenance rather than harsh chemicals.
Remove Nearby Hiding Places
Earwigs rarely spend all day inside the chair itself.
More often, they’re hiding nearby and climbing onto the chair before daylight.
Reduce shelter around your seating area by removing:
- Leaf piles
- Grass clippings
- Damp mulch touching the deck
- Stacked firewood
- Cardboard
- Unused flower pots
The fewer hiding places available, the fewer earwigs you’ll see.
Clean the Chair Thoroughly
Give the chair a good cleaning every week during peak earwig season.
Pay extra attention to:
- Mesh fabric
- Underside of the seat
- Armrests
- Frame joints
- Legs
- Drain holes
A garden hose or pressure nozzle works well for flushing insects from tight spaces.
Allow the chair to dry completely before using it again.
Reduce Moisture Around the Deck
Since earwigs depend on moisture, drying out the area makes it much less attractive.
Helpful steps include:
- Improving airflow beneath the deck
- Watering plants in the morning rather than evening
- Fixing dripping hoses or outdoor faucets
- Removing standing water nearby
Even small reductions in humidity can discourage earwigs.
Trim Nearby Plants
Plants touching the deck can act like bridges for insects.
Keep shrubs, vines, and tall flowers trimmed back several inches from your seating area.
This also improves airflow and lets sunlight reach the deck surface.
Set Simple Traps
If you’re seeing multiple earwigs every morning, traps can help reduce their numbers.
Popular options include:
- Rolled-up newspaper placed overnight
- Cardboard tubes
- Shallow containers with a little vegetable oil and soy sauce
Place traps near the chair rather than directly on it.
Dispose of trapped earwigs each morning.
Use Outdoor Barrier Treatments Only When Necessary
If earwigs continue appearing despite your efforts, a perimeter treatment around the deck may help.
Focus on treating:
- Deck supports
- Foundation edges
- Cracks around the structure
- Entry points beneath stairs
Avoid spraying the chair itself unless the product label specifically states it’s safe for outdoor furniture.
Best Prevention Habits
Keeping earwigs away is often about consistency.
- Shake out chairs before sitting.
- Store cushions indoors when possible.
- Sweep leaves off the deck regularly.
- Inspect furniture after rainy weather.
- Clean underneath the chairs every few weeks.
These small habits make outdoor furniture much less appealing as a daytime hiding place.
Mistakes That Keep Earwigs Coming Back to Your Outdoor Chair
Many homeowners unknowingly create the perfect conditions for earwigs without realizing it.
Avoiding these common mistakes can make a noticeable difference.
Leaving Cushions Outside Overnight
Outdoor cushions absorb moisture from dew and create cool, protected hiding spots.
If possible:
- Bring cushions inside overnight.
- Store them in a deck box.
- Stand them upright so they dry faster.
Dry cushions are much less attractive to earwigs.
Ignoring Damp Areas Under the Deck
The chair may not be the real issue.
Earwigs often spend the day beneath the deck, then climb onto furniture before sunrise.
Inspect underneath for:
- Wet soil
- Leaf litter
- Rotting wood
- Dense vegetation
- Standing water
Treating only the chair won’t solve a problem that starts below it.
Storing Garden Items Beside Seating
Items like watering cans, empty pots, tarps, and gardening gloves create additional hiding places.
Keep storage separate from your outdoor seating area whenever possible.
Spraying the Chair Without Treating the Surrounding Area
This is one of the biggest mistakes homeowners make.
Spraying the chair may remove the earwigs you see today, but new ones can simply crawl over from nearby hiding places the following night.
A better approach is to combine:
- Cleaning
- Moisture control
- Habitat reduction
- Targeted treatment around the deck if needed
Assuming the Chair Is Defective
Sometimes people replace perfectly good patio furniture because they believe something is wrong with it.
In reality, the chair is usually just the most convenient shelter available.
Before buying new furniture, try moving the chair or changing the surrounding environment. Many homeowners discover the problem disappears once the location changes.
What Most People Get Wrong
The biggest misconception is thinking earwigs are attracted to people.
They’re attracted to conditions—not personalities, blood types, or favorite chairs.
Once you shift your focus from the person sitting in the chair to the environment around it, finding a lasting solution becomes much easier.
Earwigs in Outdoor Chair vs. Other Patio Pests
Not every insect you find on outdoor furniture is an earwig. Knowing what you’re dealing with helps you choose the right solution instead of treating the wrong problem.
| Pest | Where It Hides | Most Active | Harmful? | Best Solution |
| Earwigs | Chair frames, mesh, under cushions | Night | Mostly harmless | Reduce moisture and hiding spots |
| Spiders | Corners, underneath furniture | Day & night | Usually harmless | Remove webs and insects they feed on |
| Ants | Chair legs, deck cracks | Day | Can become a nuisance | Locate and treat the colony |
| Stink Bugs | Under cushions and furniture covers | Fall | Harmless indoors and outdoors | Remove by hand and seal entry points |
| Pill Bugs | Damp wood, beneath decks | Night | Harmless | Improve drainage and reduce moisture |
How to Identify an Earwig
If you’re unsure whether it’s an earwig, look for these characteristics:
- Brown to dark reddish-brown body
- About ½ to 1 inch long
- Long antennae
- Six legs
- Distinctive pincers (called cerci) at the end of the abdomen
Those pincers often worry people, but they’re mostly used for defense and mating. Earwigs rarely pinch humans, and when they do, it’s usually mild.
Why Correct Identification Matters
Many patio pests thrive in different conditions.
For example:
- Ants are often searching for food.
- Spiders are following other insects.
- Earwigs are looking for moisture and shelter.
Treating an earwig problem like an ant problem won’t solve it because the attraction is completely different.
Keep Earwigs Away From Your Entire Patio and Deck
Removing earwigs from one chair is helpful, but preventing them from returning is even better.
The best long-term strategy is to make your entire outdoor living space less attractive to them.
Keep the Deck Dry
Moisture is one of the biggest reasons earwigs settle around patios.
Simple improvements include:
- Fix leaking outdoor faucets.
- Clean clogged gutters.
- Sweep away wet leaves.
- Allow good airflow beneath the deck.
- Avoid overwatering nearby landscaping.
Reduce Clutter
Earwigs love sheltered places.
Check around your deck for:
- Firewood stacks
- Cardboard boxes
- Empty flower pots
- Garden supplies
- Tarps and outdoor covers
Keeping these items organized reduces hiding opportunities.
Trim Landscaping
Bushes, vines, and mulch touching your deck create easy pathways for earwigs.
Maintain a small gap between plants and outdoor furniture whenever possible.
Clean Furniture Regularly
Outdoor furniture doesn’t need deep cleaning every week, but a quick routine helps.
Consider this checklist:
- ✔ Brush away leaves and pollen
- ✔ Hose off chairs after storms
- ✔ Check underneath furniture
- ✔ Shake cushions before use
- ✔ Store cushions during long periods of wet weather
Tiny Home Tip
If you live in a tiny house or have a compact patio, every square foot matters.
Outdoor seating is often close to gardens, storage, and entrances, which means insects don’t have far to travel. Keeping decks clean, minimizing clutter, and choosing furniture with fewer enclosed hiding spaces can significantly reduce earwig activity around small outdoor living areas.
Frequently Asked Questions About Earwigs in Outdoor Chair
Why do earwigs only hide in one outdoor chair?
Usually because that chair offers slightly better conditions, such as more shade, moisture, or protected hiding spots. Even small differences in location can make one chair much more attractive than another.
Can earwigs climb onto a second-floor deck?
Yes. Earwigs are surprisingly good climbers and can reach upper-level decks by climbing siding, support posts, stairways, nearby vegetation, or other structures.
Do earwigs live inside patio furniture?
They don’t normally build nests inside furniture, but they’ll happily use hollow frames, mesh folds, and small openings as temporary daytime shelters.
Should I worry if I find earwigs every morning?
Finding one or two occasionally is common, especially during warm, humid months. Seeing large numbers every day may indicate nearby moisture issues or an ideal hiding place that needs attention.
Will pressure washing keep earwigs away?
Pressure washing can remove dirt, debris, and insects hiding in cracks, but it works best when combined with moisture control and reducing nearby hiding places.
Are earwigs dangerous to people or pets?
No. Earwigs are considered mostly harmless. They don’t spread diseases, aren’t poisonous, and rarely pinch people unless they’re handled roughly.
Why do earwigs disappear during the day?
Earwigs are nocturnal. They spend daylight hours hiding in cool, protected locations and become active after sunset to search for food.
What to Do If Earwigs Keep Returning to the Same Outdoor Chair
If you’ve cleaned the chair, reduced moisture, and removed nearby hiding places but still find earwigs every few days, don’t assume you’ve failed.
Instead, work through this quick checklist:
- ✔ Swap the chairs to test whether the problem is the location.
- ✔ Inspect underneath the deck for damp areas.
- ✔ Look for nearby mulch, planters, or dense vegetation.
- ✔ Check the chair frame for hidden spaces where earwigs can shelter.
- ✔ Continue routine cleaning during warm, humid weather.
Most recurring earwig problems come down to the surrounding environment—not the chair itself.
If you begin seeing dozens of earwigs across your deck, patio, or around your home’s foundation, it may be worth investigating a larger moisture problem or consulting a local pest management professional.

Finding a few earwigs in your favorite outdoor chair doesn’t mean they’re attracted to you. In almost every case, they’re simply choosing the coolest, safest place to hide until nightfall. By understanding what draws them in and making a few small changes around your patio, you can usually solve the problem without replacing your furniture or reaching for unnecessary pesticides.
If you’ve had an unusual experience with earwigs choosing one chair over another, share it in the comments. Your observations might help another homeowner solve the same puzzling problem.
