If you’ve been wondering why are earwigs so bad this year, you’re not alone. Homeowners across the United States have reported seeing more earwigs crawling around patios, gardens, basements, bathrooms, and even inside kitchens than they remember in previous years.
The good news is that a sudden increase in earwigs usually has a logical explanation. Weather patterns, moisture levels, landscaping choices, and seasonal conditions all play a role in how many of these insects you encounter. Understanding what’s causing the surge can help you stop it before earwigs become regular visitors in your home.
This guide explains the biggest reasons earwig populations seem to be exploding, why they’re entering homes more often, and what you can do to keep them under control.

Why Are Earwigs So Bad This Year? The Short Answer
The simple answer is that earwigs thrive when weather conditions favor moisture and survival. Many areas have experienced a combination of mild winters, rainy springs, and humid summers, creating nearly perfect conditions for earwig populations to grow.
Unlike some insects that reproduce rapidly regardless of weather, earwigs are heavily influenced by their environment. Small changes in temperature and rainfall can lead to noticeably larger populations.
Several factors often happen at the same time:
- Higher spring rainfall keeps soil damp.
- Mild winter temperatures increase survival rates.
- Dense landscaping provides more shelter.
- Dry summer afternoons push earwigs indoors in search of moisture.
- Gardens produce plenty of food sources.
When these conditions overlap, homeowners can suddenly notice dozens of earwigs where they previously saw only one or two.
Is This Happening Across the United States?
Not every region experiences the same level of earwig activity, but many states report larger populations during years with above-average rainfall.
Areas commonly affected include:
- Pacific Northwest
- Midwest
- Northeast
- Parts of the Southeast after extended rainy periods
Even regions with hot summers can experience temporary spikes if spring weather creates ideal breeding conditions.
What Changed Compared to Previous Years?
Earwigs don’t suddenly become more aggressive. Instead, favorable environmental conditions allow more young earwigs to survive into adulthood.
Common seasonal changes include:
- Longer periods of damp weather
- Increased mulch use in landscaping
- More irrigated gardens
- Reduced winter freezes
- Higher humidity around homes
Key takeaway: Seeing more earwigs this year doesn’t necessarily mean your home has a serious infestation. Often, the outdoor population has simply increased.
10 Reasons Earwigs Are So Bad This Year
Many homeowners assume one single cause is responsible. In reality, several environmental factors usually combine to create an earwig boom.
Wetter-Than-Normal Weather Creates Ideal Breeding Conditions
Earwigs love moisture.
Rain keeps soil soft, protects eggs from drying out, and creates damp hiding places beneath rocks, leaves, mulch, and flower beds.
When spring remains consistently wet, more eggs hatch successfully, leading to larger adult populations later in the season.
Mild Winters Allow More Earwigs to Survive
Harsh winters naturally reduce insect populations.
Warmer winters allow more adult earwigs and eggs to survive until spring. That means breeding begins with a much larger population than usual.
Even a few degrees of difference during winter can significantly affect insect survival.
Hot, Dry Days Drive Earwigs Indoors
Although earwigs need moisture, they dislike direct sunlight.
Once summer temperatures rise, they leave drying soil and search for cooler, damper places like:
- Basements
- Bathrooms
- Laundry rooms
- Crawl spaces
- Garages
Many homeowners mistake this movement for an indoor infestation when the insects are actually seeking temporary shelter.
Heavy Mulch and Landscaping Provide Shelter
Fresh mulch looks attractive, but it also creates one of the best hiding places for earwigs.
Thick layers retain moisture while protecting insects from predators and sunlight.
Common outdoor hiding spots include:
- Wood mulch
- Decorative rocks
- Leaf piles
- Landscape fabric
- Firewood stacks
Keeping mulch several inches away from your home’s foundation can reduce the chances of earwigs moving indoors.
More Outdoor Lighting Attracts Their Food
Earwigs don’t usually gather around lights themselves.
Instead, outdoor lights attract smaller insects that earwigs feed on. More prey means earwigs have another reason to stay near your home.
Switching to warmer-colored outdoor bulbs may reduce insect activity around entrances.
Increased Moisture Around Foundations and Basements
Poor drainage creates ideal conditions.
Common moisture sources include:
- Leaking gutters
- Downspouts emptying beside the foundation
- Air conditioner condensation
- Standing water
- Overwatered flower beds
These damp areas become highways that lead earwigs directly toward your home’s foundation.
Gardens and Vegetable Beds Offer Plenty of Food
Earwigs eat more than insects.
They also feed on:
- Seedlings
- Lettuce
- Strawberries
- Herbs
- Soft fruits
- Flower petals
Healthy gardens naturally attract them, especially during wet seasons.
Cracks and Gaps Make Homes Easy to Enter
Earwigs don’t need large openings.
Tiny gaps around doors, windows, pipes, utility lines, and foundation cracks are often enough.
Older homes and tiny houses can be especially vulnerable if routine sealing hasn’t been done recently.
Natural Predators Have Declined in Some Areas
Birds, frogs, spiders, beetles, and certain insects help keep earwig numbers balanced.
Changes in habitat, pesticide use, and environmental conditions sometimes reduce predator populations, allowing earwigs to reproduce more successfully.
Population Cycles Can Cause Sudden Outbreaks
Some years simply favor certain insects.
Weather patterns naturally create population highs and lows. After a particularly favorable season, homeowners may notice what feels like an invasion even though it’s part of a normal population cycle.
Quick Summary: Biggest Reasons Earwigs Are Everywhere This Year
| Cause | Effect on Earwig Population |
| Wet spring | Higher egg survival |
| Mild winter | More adults survive |
| Hot afternoons | Increased indoor movement |
| Heavy mulch | Better shelter |
| Moisture near foundation | Easier access to homes |
| Productive gardens | More available food |
| Small entry gaps | Easier indoor access |
| Fewer predators | Less natural population control |
| Population cycles | Seasonal spikes |
| Humid weather | Improved survival conditions |
Why Are Earwigs Coming Into Your House This Year?
Finding earwigs inside your home can be unsettling, especially if you’ve never seen them indoors before. Fortunately, their presence usually points to environmental conditions rather than a permanent indoor infestation.
What Attracts Earwigs Indoors?
Earwigs primarily enter homes searching for moisture, cooler temperatures, and shelter.
They are especially attracted to:
- Damp bathrooms
- Basement corners
- Laundry rooms
- Under sinks
- Crawl spaces
- Utility rooms
- Areas near leaking pipes
Unlike ants or cockroaches, earwigs aren’t usually searching for human food.
Rooms Where Earwigs Are Most Commonly Found
Most indoor sightings happen in locations with higher humidity.
These include:
- Bathrooms
- Kitchens
- Finished basements
- Mudrooms
- Garages
- Storage rooms
Tiny homes can experience similar issues because compact layouts often allow humidity to spread throughout the living space. Keeping indoor humidity below about 50%, improving ventilation, and fixing leaks promptly can make the environment far less attractive to earwigs.
Signs They’re Only Seeking Shelter—Not Nesting Indoors
Most earwigs found inside don’t stay long.
You’re likely dealing with temporary visitors if:
- You only find one or two at a time.
- Most sightings happen after rain.
- They appear near doors or windows.
- They’re active mainly at night.
- No young earwigs are being found indoors.
These signs usually indicate they’re wandering in from outside rather than establishing a breeding population inside your home.
When a Few Earwigs Become an Infestation
Occasional sightings are normal during favorable weather conditions.
However, you may have a larger problem if you:
- Find multiple earwigs every day.
- Notice them in several rooms.
- Discover large numbers around your home’s exterior.
- Continue seeing them despite dry weather.
- Spot them hiding under stored boxes, rugs, or damp materials.
Persistent indoor activity often means the outdoor population around your home has grown significantly and should be addressed before it gets worse.
Are This Year’s Earwigs More Dangerous Than Usual?
Seeing dozens of earwigs where you normally see one or two can make it feel like they’ve become more dangerous. Fortunately, a larger population doesn’t mean earwigs have changed their behavior. They’re still considered nuisance pests rather than a serious threat to people or pets.
Understanding what earwigs can—and can’t—do helps you respond appropriately without unnecessary worry.
Do Larger Numbers Mean Greater Risk?
Not necessarily.
A surge in earwigs usually reflects favorable weather conditions rather than increased aggression. Even when populations are high, earwigs spend most of their time hiding during the day and become active after sunset.
The main issues associated with larger populations include:
- More insects entering homes
- Increased damage to seedlings and flowers
- Greater chance of finding earwigs in damp indoor spaces
- More hiding spots around patios, decks, and gardens
More earwigs doesn’t automatically mean a severe infestation. In many cases, improving moisture control quickly reduces their numbers.
Can Earwigs Bite People or Pets?
This is one of the biggest myths surrounding earwigs.
Earwigs have pincers called cerci at the end of their abdomen. They use them mainly for defense, catching prey, and mating—not attacking humans.
Here’s what typically happens:
- Small earwigs rarely pinch hard enough to break skin.
- Larger earwigs may give a light pinch if handled.
- Their pincers contain no venom.
- They do not spread diseases to people.
- They are not dangerous to dogs or cats.
Most people never experience a pinch because earwigs prefer to run away rather than defend themselves.
Do They Damage Homes, Furniture, or Food?
Unlike termites or carpenter ants, earwigs do not destroy wood or structural materials.
They also don’t:
- Tunnel through walls
- Eat insulation
- Damage wiring
- Ruin furniture
Indoors, they’re mainly a nuisance.
Outdoors is where they can become more problematic. Large populations sometimes feed on:
- Vegetable seedlings
- Lettuce
- Strawberries
- Dahlias
- Marigolds
- Soft fruits
- Young ornamental plants
Gardeners often notice the damage as irregular holes in leaves or petals.
Myth vs. Fact About Earwig Infestations
| Myth | Fact |
| Earwigs crawl into people’s ears. | False. This old myth has no scientific basis. |
| Earwigs are poisonous. | False. They have no venom and aren’t poisonous. |
| They destroy houses. | False. They don’t damage structural wood. |
| Seeing one means hundreds are inside. | Not always. Most indoor sightings involve wandering individuals. |
| Wet weather increases earwig activity. | True. Moisture is one of the biggest drivers of population growth. |
What most people get wrong: Many homeowners panic after seeing several earwigs indoors, assuming they’re breeding inside the house. In reality, most infestations begin outdoors, and the insects simply wander inside while searching for moisture and shelter.
Do This Immediately If You’re Seeing More Earwigs Than Ever
Waiting until earwig numbers become overwhelming usually makes control more difficult. Taking action early can dramatically reduce the number entering your home.
The goal isn’t just killing earwigs—it’s making your property less attractive to them.
Remove Excess Moisture Around Your Home
Moisture is the number one reason earwigs stay near a house.
Start by checking for:
- Leaking outdoor faucets
- Clogged gutters
- Poor drainage
- Standing water
- Overwatered landscaping
- Damp crawl spaces
Simple fixes often eliminate the conditions earwigs need to survive.
Seal Common Entry Points
Even tiny openings allow earwigs inside.
Inspect and seal:
- Foundation cracks
- Gaps around utility pipes
- Door thresholds
- Window frames
- Dryer vents
- Cable and plumbing penetrations
Adding weatherstripping and fresh caulk can significantly reduce indoor sightings.
Reduce Outdoor Hiding Places
Removing shelter forces earwigs to relocate elsewhere.
Focus on:
- Raking leaves regularly
- Moving firewood away from the house
- Trimming dense ground cover
- Keeping mulch 6–12 inches from the foundation
- Removing piles of rocks or lumber
- Cleaning clutter from patios and decks
These changes also discourage other moisture-loving pests.
Use Safe Indoor and Outdoor Control Methods
Chemical sprays aren’t always necessary.
Many homeowners successfully reduce earwigs using:
- Sticky traps along walls
- Rolled-up damp newspaper traps overnight
- Shallow containers filled with vegetable oil and soy sauce
- Diatomaceous earth around dry entry points
- Outdoor insect barriers when populations are unusually high
If using pesticides, always follow the product label and avoid applying them where children or pets regularly play.
When Traps Work—and When They Don’t
Traps can be very effective for monitoring activity.
They work best when:
- Earwig numbers are still low
- Moisture problems have already been corrected
- Placed near known hiding spots
- Checked daily
They’re much less effective if damp conditions remain unchanged. Killing individual earwigs won’t solve the problem if your yard continues providing ideal habitat.
Quick Action Checklist
✔ Fix leaks and drainage issues
✔ Lower indoor humidity
✔ Seal cracks around doors and windows
✔ Remove damp yard debris
✔ Move mulch away from the foundation
✔ Set traps to monitor activity
✔ Inspect after heavy rainfall
Mistakes That Can Make an Earwig Problem Worse
Many homeowners unknowingly create the perfect environment for earwigs while trying to maintain a healthy yard. Avoiding a few common mistakes can make a noticeable difference.
Overwatering Landscaping
Healthy plants need water, but constantly soaked soil creates ideal earwig habitat.
Instead of watering every day:
- Water deeply but less frequently.
- Water early in the morning.
- Allow the top layer of soil to dry between watering sessions when appropriate.
This benefits many plants while making conditions less favorable for earwigs.
Leaving Leaf Piles and Mulch Against the House
Organic debris traps moisture and provides shade.
Pay special attention to:
- Leaf piles
- Pine needles
- Grass clippings
- Compost
- Decorative bark mulch
Maintaining a clear buffer between landscaping and your home’s foundation reduces the likelihood of insects moving indoors.
Ignoring Gutters and Standing Water
Overflowing gutters often keep soil wet for days after rainfall.
Inspect your home regularly for:
- Downspouts that empty next to the foundation
- Pooling water after storms
- Blocked drainage channels
- Low spots in the yard
Correcting drainage problems helps prevent not only earwigs but also mosquitoes and other moisture-loving pests.
Keeping Porch Lights On All Night
Bright exterior lighting attracts flying insects.
Since earwigs feed on many small insects, an active food source encourages them to remain nearby.
Consider:
- Switching to warm-colored LED bulbs
- Using motion-sensor lighting
- Turning unnecessary lights off overnight
Using Sprays Without Fixing the Source
Many people rely solely on insecticides.
Unfortunately, sprays provide only temporary relief if moisture, shelter, and food remain available.
The most effective long-term strategy combines:
- Moisture control
- Habitat reduction
- Entry-point sealing
- Targeted trapping
- Limited pesticide use only when necessary
Expert tip: If earwigs keep returning despite repeated treatments, inspect your yard instead of applying more insecticide. Solving the environmental conditions almost always delivers better long-term results than repeated spraying alone.
Earwigs This Year vs. Other Common Household Pests
Not every insect responds to weather in the same way. Comparing earwigs with other common household pests helps explain why you’re seeing more of them this year—and whether you should be equally concerned about other bugs around your home.
| Pest | Main Cause of Population Boom | Biggest Attraction | Should You Worry? |
| Earwigs | Wet weather and mild winters | Damp hiding places | Usually low risk |
| Silverfish | High indoor humidity | Paper, cardboard, fabrics | Moderate |
| Pill bugs | Moist soil | Organic debris | Low |
| Cockroaches | Food and moisture | Kitchens and garbage | High |
| Ants | Easy access to food | Sweet and greasy foods | Moderate |
Earwigs vs. Silverfish
Both insects thrive in humid environments, but they behave differently.
Earwigs:
- Usually come indoors from outside.
- Prefer damp outdoor hiding spots.
- Rarely stay indoors permanently.
- Feed on insects and plants.
Silverfish:
- Often live indoors year-round.
- Feed on paper, glue, books, and clothing fibers.
- Reproduce inside homes more readily.
- Frequently appear in bathrooms, attics, and storage areas.
If you’re seeing both pests, excess indoor humidity is likely contributing to the problem.
Earwigs vs. Pill Bugs
Pill bugs (sometimes called roly-polies) are another moisture-loving pest.
Similarities include:
- Active after rain
- Hide under mulch and rocks
- Prefer cool, damp conditions
- Often found near foundations
The difference is that pill bugs rarely venture far indoors, while earwigs are much more likely to wander inside searching for shelter.
Earwigs vs. Cockroaches
Many homeowners panic after spotting an earwig because they mistake it for a cockroach.
Fortunately, they’re very different.
| Feature | Earwig | Cockroach |
| Pincers | Yes | No |
| Carries diseases | Very unlikely | Can spread bacteria |
| Damages food | Rarely | Frequently |
| Breeds indoors | Uncommon | Common |
| Main attraction | Moisture | Food and moisture |
Cockroaches require immediate attention, while occasional earwigs are usually managed through moisture control and exclusion.
What Tiny Home Owners Should Know
Tiny homes can experience insect issues differently than larger houses.
Because living spaces are compact:
- Humidity spreads more quickly.
- Small plumbing leaks become noticeable faster.
- A single entry gap may allow multiple insects inside.
- Storage areas can become damp if ventilation is poor.
Running a dehumidifier when needed, using exhaust fans, and checking door seals seasonally can greatly reduce the chance of earwigs and other moisture-loving pests moving into a tiny home.
How to Prevent Another Earwig Surge Next Season
The best way to deal with earwigs is to prevent them before their population explodes. Since weather isn’t something you can control, focus on making your property less inviting throughout the year.
Small maintenance tasks performed consistently often produce better results than large pest-control efforts after earwigs have already arrived.
Yard Maintenance Checklist
Healthy landscaping can still discourage earwigs.
Use this seasonal checklist:
- Remove fallen leaves regularly.
- Keep shrubs trimmed away from exterior walls.
- Store firewood at least 20 feet from the house when possible.
- Replace overly thick mulch with a thinner layer.
- Remove weeds that trap moisture.
- Clean gutters before rainy seasons.
- Keep compost piles away from the foundation.
Moisture Control Tips
Since moisture is the biggest attraction, reducing damp conditions should be your first priority.
Check these areas regularly:
- Basement humidity
- Crawl spaces
- Outdoor faucets
- Irrigation systems
- Air conditioner drain lines
- Roof drainage
Indoor humidity between 30% and 50% is generally comfortable for people while being less attractive to many household pests.
Landscaping Changes That Discourage Earwigs
A few simple adjustments can make a noticeable difference.
Consider:
- Using gravel borders next to foundations.
- Improving drainage around flower beds.
- Avoiding excessive mulch depth.
- Elevating garden containers where practical.
- Choosing irrigation methods that avoid constant surface moisture.
These changes also benefit many other aspects of landscape health.
Seasonal Home Maintenance Schedule
Spring
- Inspect for winter damage.
- Seal foundation cracks.
- Clean gutters.
- Test drainage after rain.
Summer
- Reduce unnecessary watering.
- Trim vegetation touching the house.
- Watch for increased nighttime activity.
Fall
- Remove leaves quickly.
- Store firewood properly.
- Inspect weatherstripping before colder weather.
Winter
- Repair exterior caulking.
- Plan landscaping improvements for spring.
- Address any indoor moisture problems.
Early Warning Signs to Watch For
Catching an increase early makes control much easier.
Watch for:
- Earwigs under flower pots
- Clusters beneath outdoor furniture
- Increased activity after rainfall
- Damage to seedlings
- Frequent sightings near basement doors
- Damp mulch that stays wet for several days
Expert tip: Regular inspections after heavy rain can reveal problem areas before earwigs begin moving indoors.
Frequently Asked Questions About Why Earwigs Are So Bad This Year
Why are there so many earwigs this summer?
Warm temperatures combined with rainy weather create ideal breeding conditions. Moist soil improves egg survival, while humid environments provide plenty of shelter and food.
Why do earwigs suddenly appear after rain?
Rain saturates the ground and often floods the small spaces where earwigs hide. As the soil becomes overly wet, they move to drier locations, including patios, garages, and homes.
Why are earwigs entering my house at night?
Earwigs are nocturnal insects. They become active after sunset and may enter through tiny gaps while searching for moisture, cooler temperatures, or shelter.
Will earwig numbers go down on their own?
In many cases, yes. Populations often decline as weather becomes drier or colder. However, homes with persistent moisture problems may continue attracting earwigs even after outdoor numbers decrease.
Does weather affect earwig populations every year?
Yes. Rainfall, humidity, and winter temperatures all influence how many earwigs survive and reproduce. Years with mild winters and wet springs often produce larger populations.
Should I call a pest control company for earwigs?
Professional treatment may be worthwhile if you’re finding large numbers indoors every day, DIY methods haven’t worked, or moisture issues have already been corrected but the problem persists.
What naturally keeps earwigs away?
Reducing moisture, removing yard debris, improving drainage, sealing entry points, and maintaining proper ventilation are among the most effective natural ways to discourage earwigs.
Are earwigs worse for tiny homes?
Not necessarily. Tiny homes aren’t more attractive to earwigs by design, but limited space means humidity can build up more quickly if ventilation is poor. Keeping moisture under control and sealing small gaps are especially important in compact living spaces.
When an Earwig Problem Means It’s Time for Professional Help
Most earwig problems can be solved with better moisture control, habitat reduction, and sealing entry points. However, there are situations where professional pest control is the fastest and most effective solution.
Knowing when you’ve crossed the line from a seasonal nuisance to a recurring infestation can save time, money, and frustration.
Signs DIY Methods Aren’t Enough
If you’ve already addressed the common causes but continue finding earwigs every day, the issue may be larger than it appears.
Consider calling a pest management professional if you notice:
- Dozens of earwigs inside your home each week
- Large clusters around the foundation at night
- Persistent infestations despite sealing cracks and reducing moisture
- Extensive damage to flowers, vegetables, or seedlings
- Earwigs returning shortly after treatment
Professionals can identify hidden moisture problems, breeding areas, and entry points that are easy to overlook.
How to Identify a Recurring Outdoor Population
An outdoor population often causes repeated indoor sightings.
Walk around your property after sunset with a flashlight and inspect areas such as:
- Beneath mulch
- Around landscape edging
- Under flower pots
- Near outdoor faucets
- Along retaining walls
- Around basement window wells
- Under decorative stones
If you find dozens of earwigs concentrated in these locations, reducing outdoor habitat should be your first priority.
What a Pest Control Inspection Typically Involves
A reputable pest control technician will usually:
- Inspect the home’s exterior.
- Identify moisture sources.
- Check landscaping near the foundation.
- Look for entry gaps around doors, windows, and utility lines.
- Recommend habitat modifications.
- Apply targeted treatments only where needed.
Many professionals emphasize prevention first because eliminating favorable conditions often provides longer-lasting results than repeated pesticide applications.
How Long Does It Take to Reduce Large Earwig Populations?
Results depend on the underlying cause.
Here’s a general timeline:
| Action | Typical Time to See Results |
| Removing moisture sources | 1–3 weeks |
| Sealing entry points | Immediate reduction in new indoor visitors |
| Habitat cleanup | 2–4 weeks |
| Outdoor baiting or targeted treatment | Several days to 2 weeks |
| Seasonal weather changes | Often reduces activity naturally within a few months |
Consistency is key. Even the best treatment won’t provide lasting relief if damp conditions remain around your home.
Final Takeaways on Why Earwigs Are So Bad This Year
If you’ve been asking, “Why are earwigs so bad this year?”, the answer usually comes down to a combination of weather and environmental conditions—not because earwigs have become more aggressive.
Remember these key points:
- Wet springs and mild winters allow more earwigs to survive.
- Hot, dry afternoons often push them indoors in search of moisture.
- Most indoor earwigs are accidental visitors rather than permanent residents.
- Reducing moisture is far more effective than simply spraying insecticides.
- Routine home maintenance helps prevent future outbreaks.
Whether you live in a traditional home, cabin, or tiny house, the same principles apply. Dry conditions, good ventilation, and regular exterior maintenance make your property far less appealing to earwigs and many other nuisance pests.
