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: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.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.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.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.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.Related: Earwigs are not..How to control earwigsAlthough 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.If you have concerns or need additional help in dealing with earwig problems in your home, contact a trusted pest control service for earwigs.
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 AnatomyClaw-like forceps called cerci protrude from the end of the abdomen (males’ are more curved)Approximately ½ to 1¼ inches in lengthA segmented, soft body with a head, thorax, and abdomenDark reddish-brown body color, although some species are brown or blackFlat, elongated shapeSix brownish yellow legsMay have wings or forewingsEarwigs in ArizonaThere 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 ImpostersPeople 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 longIt has three appendages (about the same length of the body) that look like tails attached to the abdomenThe bug’s body is a uniform silver colorIt has no wingsIt has a soft, oval, and flat body that really quite resembles a fishYou have firebrats if:The bug is ¼ to ½ inch longIt has a body that is thicker at the front and narrower in backIt lacks wingsIt has three appendages (about the same length of the body) attached to the abdomen that look like tailsIts body is a mottled grayish-brown colorThere 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 IdentificationLack 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 conditionsDoes it shelter in dark, moist areas (under stones, boards, sidewalks, or soil) during the day and is active at night, it may be an earwigKnow the Bug By What It EatsEarwigs do eat other bugs, but they also have a taste for some favorite garden plants, including:BeansButterfly bushCorn silkDahliasHollyhocksLettuceMarigoldsPotatoesRosesSquashStrawberriesZinniasIf 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 bindingCerealsFabrics: cotton, linen, and rayonGrainsWallpaper paste and sizingWhich 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 PincersThe 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 MoistureIndoors or out, earwigs gravitate to moist areas. They feed at night and hang out in dark, moist places during the day.Common Earwig Daytime HangoutsSprinkler system expansion jointsDrip irrigation system connectorsBeneath concrete slabs or larger rocks located near irrigated areasUnderneath loose clods of dirtBeneath wood boardsUnder densely grown vines or weedsWithin damaged fruit (such as peaches or apricots)The underside of rotted woodOmnivorous EarwigsEarwigs are omnivores, and their preferred foods include:AphidsMitesInsect eggsMarigoldsPetuniasDahliasHostasSoft fruitsIndoor EarwigsEarwigs inside the home pose no real danger to humans, despite old tales of their ear canal-crawling, brain-sucking proclivities.Why Earwigs Come InsideArid weather conditions make it hard to find moist areas outsideOutdoor temperatures dip too lowTo search for food, although little they find indoors appeals to themHow Earwigs Enter HousesFor earwigs, it is all about moisture, and so they may follow a moisture trail into the houseBoxes or household items stored in a damp area and brought inside may transport earwigsSince foundation cracks often coincide with moisture, earwigs find their way in through small exterior openingsEradicating Earwigs, Indoors and OutEarwigs 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 barriersSeal both outdoor cracks as well as indoor ones (baseboards, tiles, and flooring) with caulkKeep any moisture harboring items away from the home’s foundationInstall 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 sinksYard maintenanceDo not overwater plants and gardensRemove plant and leaf litter, woodpiles, rolled-up carpets, tarps, and pool or patio umbrellas and equipment from the home’s perimeterTrim landscaping so it does not touch the houseKeep downspouts and drains in good working order so that they properly remove and disperse waterRemove ivy growing on the side of the houseClean out roof guttersGrade gardens and landscaping so that groundwater flows away from structures and does not pool anywhereMake sure crawlspaces are ventilated so they do not become dampLight and the Average EarwigIt 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 ProfessionalAs 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!
