Earwigs in Arizona: Arizona’s Most Wanted Pests #10

February 13, 2019 - By: Nathan Woolf

If you’ve lived in Arizona for long, you know that our sunny, warm state has many good qualities, including a varied climate with mild winters. But with beautiful weather also comes the drawback of increased pest activity. There are many different bugs that find the climate hospitable in Arizona, and Blue Sky Pest Control is dedicated to effectively controlling them in and around homes and businesses.

Our latest blog series entitled, “Arizona’s Most Wanted Pests” introduces you to the top 10 pest concerns that invade the Arizona area. We’ll give you tips, tricks, and what to look for when encountering the most problematic pests. This month we feature #10 on the list, Earwigs, providing you with the facts and information to better understand this abundant and commonly seen insect.

Often called “the pincher bug,” earwigs are tiny black bugs that often have red and yellow coloring with an elongated, thin body. They are known as the pincher bug because of their distinct tail that features tiny pincers. Often found under debris and rocks, Earwigs can be found under virtually anything, and favor decaying organic matter, such as leaf litter, yard clippings, and gardens. Earwigs can live indoors and prefer to take refuge in dark places. Not uncommon in homes and around the yard and gardens these bugs are mostly harmless to humans, but there are a few things you should know.

Five facts about earwigs:

1. Earwigs have six legs, providing another way to identify them.

Besides the two pincers, another way to distinguish whether or not the bug you’re seeing is an earwig is by how many legs it has. Earwigs have six tiny legs that allow them to quickly crawl.

1. They use their pincers to fight, but pose little threat to humans.

What are the pincers on an earwig good for? If a predator comes at an earwig, they can most likely use their pincers to fight them off. Earwigs might also use their pincers to gather food. Although the sharp pincers of an earwig might be intimidating to humans, being pinched by an earwig won’t cause damage if they meet your skin.

1. Earwigs love moist areas.

Earwigs like to hide in the gaps between concrete slabs that is frequently moistened (near sprinklers or just beneath hose spigots), and in soil near drip systems.

1. They mostly stay outside.

Since earwigs love moisture, they will most likely stay outside, rather than infest your home. However, if the outdoor space an earwig is in is too dry, they will likely pick up and move somewhere with more moisture, such as a basement or cool crevice in your home.

1. Earwigs might make their way into your home.

Earwigs mostly live outdoors, but they may come inside when it’s cold or where there are gaps they can easily use to come/go. People can bring them in on/in anything, including shoes, camping gear, pool toys, and anything else that spends much time outside before being brought inside. If you do find them in your home, they are typically nocturnal and prefer dark crevices with moisture, common sightings are in bathrooms and around sinks.

How to control earwigs

Although we recommend a professional pest control service for bugs, there are some things you can do to keep earwigs out of your home or office.

Keep the inside of your home or office dry. Earwigs like moisture, so make sure to fix leaky pipes, spigots, or drip/sprinkler systems quickly. Any regularly moist area is a potential harborage area for them.
Regular inspection and cleaning around the home.
- Indoors: Earwigs like to hide under objects and are commonly found inside homes under garbage cans, couches, and other furniture that creates large covered areas but doesn’t often move. Periodically moving these items and cleaning beneath them, either with a vacuum and light cleaning solution can help keep them from becoming a home for earwigs (and other pests, too).
- Outdoors: Reduce clutter in the yard, such as leaf litter, toys, tools, and building supplies. Either move them or elevate them enough to allow airflow, which prevents moisture from accumulating beneath, creating ideal conditions for earwigs.
Seal any gaps. To help prevent any bugs from getting into your home, make sure windows, doorways are sealed with weather stripping (if you can see light through the gaps in the doors, earwigs can get in). Ensure gaps around plumbing and other utility lines entering the house (pipes, A/C lines, cable/satellite wire entry holes, dog doors) are sealed or screened properly. Focus on those items near flower beds or moist areas where earwigs are more likely to enter.

Earwigs Are Not…

March 10, 2015 - By: Nathan Woolf

…brain-burrowing terrors from a horror movie! Nonetheless, most people find them pretty creepy looking, and commonly confuse them with two other pests: firebrats and silverfish.

In folklore, earwigs came out at night and crawled into the ears of sleeping people. Once in the ear, people believed the creatures bored into the brain. The fact that earwigs often hid in the powdered wigs of eighteenth century ladies and fops merely bolstered their fearsome reputation. However, despite their sinister appearance and scary reputation, they have no brain sucking or ear invading intentions.

Basic Earwig Anatomy

Claw-like forceps called cerci protrude from the end of the abdomen (males’ are more curved)
Approximately ½ to 1¼ inches in length
A segmented, soft body with a head, thorax, and abdomen
Dark reddish-brown body color, although some species are brown or black
Flat, elongated shape
Six brownish yellow legs
May have wings or forewings

Earwigs in Arizona

There isn’t just one earwig; there are many! Although there are numerous species of these insects, the most commonly encountered type in Arizona is the Forficula auricularia earwig, or European earwig, which is an introduced species. All earwigs are omnivores and eat plants and other insects. Earwigs sometimes cause problems for certain garden plants, ornamental plants and some types of small trees. In Arizona, they may enter houses to seek out moisture. However, earwigs normally hide in dark, moist areas such as under potted plants or mulch.

Earwig Imposters

People often confuse earwigs, silverfish, and firebrats. Properly dealing and eradicating a pest problem requires knowing the creature you are up against.

You may have silverfish if:

The bug is ¼ to ½ inch long
It has three appendages (about the same length of the body) that look like tails attached to the abdomen
The bug’s body is a uniform silver color
It has no wings
It has a soft, oval, and flat body that really quite resembles a fish

You have firebrats if:

The bug is ¼ to ½ inch long
It has a body that is thicker at the front and narrower in back
It lacks wings
It has three appendages (about the same length of the body) attached to the abdomen that look like tails
Its body is a mottled grayish-brown color

There are other things that all three creatures have in common, such as antennae and six legs, but discerning the differences in those parts requires a closer inspection than most people are willing to undertake.

If You Cannot (or Will Not) Get Close Enough to Make a Visual Identification

Lack the desire to inspect the fine details of the creature at hand? Sometimes looking at its behavior helps identify them.

Does it fly? It may be an earwig.
Does it run in short spurts of movement interspersed with quick stops? It may be a silverfish or firebrat.
Is it unable to climb smooth vertical surfaces (such as sink or tub walls)? It could be a silverfish or firebrat.
Can it scurry up a rougher vertical wall? It may be an earwig.
Is it in a dry area? It could be a silverfish or firebrat, as they prefer dryer conditions
Does it shelter in dark, moist areas (under stones, boards, sidewalks, or soil) during the day and is active at night, it may be an earwig

Know the Bug By What It Eats

Earwigs do eat other bugs, but they also have a taste for some favorite garden plants, including:

Beans
Butterfly bush
Corn silk
Dahlias
Hollyhocks
Lettuce
Marigolds
Potatoes
Roses
Squash
Strawberries
Zinnias

If you find a bug eating books or other paper materials, it is probably a silverfish or firebrat. They prefer food that is high in protein, sugar, and starch. This means you can often find them eating (read: destroying):

Book binding
Cereals
Fabrics: cotton, linen, and rayon
Grains
Wallpaper paste and sizing

Which Ones Are Worse?

Silverfish and firebrats are the bane of book collectors. As previously mentioned, if the damage is to books, fabrics, and other dry, cellulose-based materials, firebrats and silverfish are the likely culprits.

Earwigs pose problems for certain plants, such as soft fruits and certain flowers. However, they also eat harmful garden insects like aphids.

A Word About those Pincers

The pincers, or cerci, are actually sensory organs, and earwigs use them to feel things and to groom themselves. However, they also use them for defense and capturing prey. Some swear they experienced excruciating pain due to an earwig pincer pinch—but even if an earwig bites, the most you would feel is a little pinch and nothing more.

Combatting Earwigs Indoors and Out

March 5, 2015 - By: Nathan Woolf

If fearsome-looking bugs featuring a set of nasty-looking pincers are scurrying about your home, chances are they are earwigs. While not dangerous to humans, earwigs wreak havoc on certain plants, although they also eat many “bad” bugs. Nonetheless, most people could do without their presence in their homes and yards. The best method of dealing with them is preventing their entry into your home.

Earwigs Love Moisture

Indoors or out, earwigs gravitate to moist areas. They feed at night and hang out in dark, moist places during the day.

Common Earwig Daytime Hangouts

Sprinkler system expansion joints
Drip irrigation system connectors
Beneath concrete slabs or larger rocks located near irrigated areas
Underneath loose clods of dirt
Beneath wood boards
Under densely grown vines or weeds
Within damaged fruit (such as peaches or apricots)
The underside of rotted wood

Omnivorous Earwigs

Earwigs are omnivores, and their preferred foods include:

Aphids
Mites
Insect eggs
Marigolds
Petunias
Dahlias
Hostas
Soft fruits

Indoor Earwigs

Earwigs inside the home pose no real danger to humans, despite old tales of their ear canal-crawling, brain-sucking proclivities.

Why Earwigs Come Inside

Arid weather conditions make it hard to find moist areas outside
Outdoor temperatures dip too low
To search for food, although little they find indoors appeals to them

How Earwigs Enter Houses

For earwigs, it is all about moisture, and so they may follow a moisture trail into the house
Boxes or household items stored in a damp area and brought inside may transport earwigs
Since foundation cracks often coincide with moisture, earwigs find their way in through small exterior openings

Eradicating Earwigs, Indoors and Out

Earwigs that enter homes in search of water and food often find the indoor climate hostile.

Most home interiors are far too dry for moisture-loving earwigs, and, as a result, they dry up and die rather quickly.
Sweep up or vacuum up any earwigs found indoors, but be sure to kill them or they will just come back in, given the chance.

Keeping earwigs out requires barriers and unappealing conditions (dryness).

Maintain good barriers

Seal both outdoor cracks as well as indoor ones (baseboards, tiles, and flooring) with caulk
Keep any moisture harboring items away from the home’s foundation
Install new or replace worn weatherstripping around doors and windows, as this keeps earwigs out and prevents light from seeping out around door edges (more on that below!)
Place steel wool around pipe openings beneath sinks

Yard maintenance

Do not overwater plants and gardens
Remove plant and leaf litter, woodpiles, rolled-up carpets, tarps, and pool or patio umbrellas and equipment from the home’s perimeter
Trim landscaping so it does not touch the house
Keep downspouts and drains in good working order so that they properly remove and disperse water
Remove ivy growing on the side of the house
Clean out roof gutters
Grade gardens and landscaping so that groundwater flows away from structures and does not pool anywhere
Make sure crawlspaces are ventilated so they do not become damp

Light and the Average Earwig

It seems counterintuitive, but earwigs have a natural curiosity for light. Outdoor lighting may be one culprit in attracting large numbers to your yard. With a nearby window (or even light streaming out from the inside), earwigs may find a way into your home. Consider switching to yellow or sodium vapor light bulbs, and maintain weatherstripping.

Trap Them If You Dare—or Call a Professional

As mentioned, common damp yard items can attract earwigs—but you can use this to your advantage. Provide a place that appeals to them and you may be able to get rid of a lot of them once they discover the bounty. Some people even use specialized traps filled with “attractive” concoctions containing everything from beer to the water in which tuna is packed.

Alternatively, remove the debris and lawn items that attract them. They may just stay away on their own!

5 Places Earwigs Like To Hide

November 21, 2012 - By: Nathan Woolf

Earwigs are a common pest in Arizona, though not one that you need to be too concerned about inside your home. Earwigs prefer to live outdoors and feed on vegetation as well as other insects. Though they look formidable with their long, flat bodies and forceps, they are harmless to people and animals.

Earwigs live mainly outside the home, and they don’t establish themselves indoors regularly. With that being said, they can end up inside in many ways. Sometimes it’s as simple as an earwig that lives in your garden or around the foundation of your home crawling up your house and entering through an opening. Especially during particularly hot summers, earwigs have a tendency to end up inside.

Earwigs are night travelers, staying hidden during hot days. Similar to bed bugs, earwigs are considered to be hitchhikers, scurrying into hiding spots before the sun comes up. As such, earwigs can travel a long distance on unsuspecting items, including:

1) Newspapers and Mail

It’s not unheard of for an earwig to end up in the house after climbing into a newspaper delivery bag in the morning. After all, earwigs thrive outdoors in damp environments and try to find places to hide before the sun comes up. A newspaper tossed onto your front step or lawn early in the morning is a great place for an earwig to take up hiding. Just like the newspaper, the mail is an easy target for earwigs. You’ll probably find an earwig among your catalogs and bills more than once a year, as they thrive in the dark folds of your mail.

2) Luggage

Earwigs can climb into dark, damp suitcases fairly easily. The dark environment filled with clothing is ideal for earwigs that seek refuge from daylight. Interestingly, earwigs can’t crawl long distances and they rarely fly, but they travel very far due to their ability to hitchhike on luggage.

3) Cardboard boxes

Cardboard boxes, especially those that have been sitting outside or in a damp, dark area, are prime hiding spots for earwigs. The flaps on a cardboard box offer earwigs shelter. It is not uncommon for someone to pick up a cardboard box of items at a garage sale and find a few earwigs among their new possessions.

4) Outside the Home

Earwigs thrive in dark, damp areas. Because Arizona is so dry, that means they’re often driven deep into the soil or under rocks, stepping stones, and downspouts. You might be working in your garden, pick up a potted plant and find earwigs scurrying underneath it.

5) Inside the Home

When earwigs do get inside, often on some of the items listed above, they move quickly and can show up just about anywhere. We’ve heard plenty of stories of people screaming when they see an earwig in the shower or find one on their towel or even in their beds.

The important thing to remember about earwigs is that though they’re a nuisance and look menacing, they are harmless to you and your pets. Although they can’t cause you any physical harm, they can wreak havoc on your garden and can be controlled with a pest control service.
