The Small Flies That Arizona Residents Often Mistake For Fleas Or Chiggers

Flies are disgusting and annoying insect pests that are, unfortunately, all to common within homes. In Arizona, one of the most common fly pests belonging to the Diptera order are commonly known as no-see-ums, also known as sandflies or biting midges. No-see-ums belong to the Ceratopogonidae family, which consists of more than 5,000 species that span all regions of the world, even polar regions. The no-see-ums that exist in Arizona and the rest of the southwest belong to the Culicoides genus. This genus includes species that are known for facilitating the spread of disease. While no-see-ums in Arizona are not considered disease vectors, they can still spread disease causing bacteria to humans and human food sources. When these insects bite, their saliva is injected into the human bloodstream, causing initial pain and lasting irritation. Persistent scratching of bite wounds has been known to lead to infection.

No-see-ums are nearly invisible to the naked eye, and they are sometimes referred to as gnats. Despite their small size, these insects are known for inflicting painful and irritating bites. Each year, entomologists who specialize in pest control at the University of Arizona’s extension office receive numerous calls from residents who believe that they have been bitten by fleas or chiggers. However, after discussing the bite wounds and symptoms with residents, the entomologists learn that these residents were actually bitten by no-see-ums.

Since no-see-ums are no larger than 1/16 of an inch in body length, they can easily fly through window screens before biting residents within their homes. The presence of these insects are virtually impossible to prevent within homes, but keeping garbage and open food sources minimal can go a long way to prevent these insects from becoming an issue within homes. No-see-ums are most active in Arizona during the summer months in the morning and early afternoon.

Have you ever found what you believe were no-see-ums within your home?

Can The Giant Redheaded Centipede Be Found In Arizona?

Centipedes are unpleasant creatures, and most species inflict venomous and painful bites to humans. Most people do not often have contact with centipedes, except of course for the common house centipede, which can be found all over North America where they commonly infest homes. These centipedes rarely grow beyond an inch in a half, and given how unsettling these creatures are, you can imagine how unpleasant it must be to spot a centipede exceeding 8 inches in length. Unfortunately, one such species that grows this large can be found in Arizona, but luckily, the species does not enter households as often as the house centipede in the state. This species is commonly known as the “redheaded centipede,” or the “giant desert centipede,” and their massive size allows them to feed on lizards, frogs and rodents. As you can imagine, sustaining a bite from one of these centipede species is extremely unpleasant. In fact, one redheaded centipede specimen was recently found to have killed a snake.

The redheaded centipede can be found in the southwest desert regions of the US, but the species is also found in Louisiana, proving that it does not have a problem surviving in humid conditions. This species even prefers to dwell in dark and humid areas, which is why stumbling across a specimen in your basement is not out of the question. It’s best for people to avoid this centipede species entirely, as their penetrating bite alone is painful, let alone the stinging sensation produced by the venom. This species’ mouthparts consists of two large fangs that can easily pierce skin. In most bite cases, victims develop local swelling and pain that subsides within a matter of days, but some rare cases have seen bite victims experience systemic symptoms, such as nausea and headaches. Fatalities due to this species’ bite is not impossible, as one bite case saw a man die from a heart attack.

Have you ever spotted a centipede that you believe exceeded 6 inches?

What You Need To Know To Minimize The Risk Of Sustaining Bites From West Nile-Infected Mosquitoes

What You Need To Know To Minimize The Risk Of Sustaining Bites From West Nile-Infected Mosquitoes

As many Arizona residents may have already learned, the west Nile virus is now a permanent component of southern Arizona’s ecosystem, making the diseased insects particularly prevalent around residential and urban areas of Phoenix and Tucson. Last May, state officials collected 87 mosquito specimens carrying the virus, which is up from a mere seven samples found in the same area of Phoenix last year. Unfortunately, the west Nile virus is not the only mosquito-borne disease to fear in Arizona, as officials also collected 53 specimens that were carrying St. Louis Encephalitis. This figure is up from only two cases of the disease found this time last year. The first west Nile disease case of the year in Arizona was confirmed last February in Maricopa county, and the mosquito season lasts from May through October in the state, so mosquito activity is not yet at its peak. In addition to this case, another west Nile disease case has likely infected a resident of Pima County. Needless to say, mosquito bites are of greater concern than ever before in Arizona. However, there are plenty of precautions that residents can take to prevent bites.

The west Nile virus is spread by the Aedes aegypti mosquito species, which is now abundant in southern Arizona. This particular mosquito species relies almost exclusively on standing water sources located in residential and urban areas in order to breed. Yards that contain an abundance of stagnant water sources will certainly see an abundance of mosquitoes. Removing standing water from residential yards will keep these mosquitoes away from human-populated areas and will also decrease the overall population size of the species. Even containers as small as a bottle cap can hold a sufficient amount of water for larval development. It is also important for residents to apply mosquito repellent before setting foot outdoors, especially when planning to remain outdoors for an extended period of time. The Centers for Disease Control and Prevention recommend using repellents that have been approved by the Environmental Protection Agency. Products that contain DEET and are designed to repel Aedes Aegypti mosquitoes are the most important aspects of an effective mosquito repellent.

Do you worry about sustaining bites from disease-carrying mosquitoes around your home?

A Citywide Outbreak Of Odorous Stink Beetles Perplex And Disgust Residents

A Citywide Outbreak Of Odorous Stink Beetles Perplex And Disgust Residents

Beetles may be the most species-rich group of insects on the planet, and many beetle species have been categorized as pests. However, most beetle pests infest and damage trees and plants, as many gardeners have come to learn. Very few beetle pests invade homes, and beetle epidemics that see thousands of specimens invading homes and business in large cities are unheard of, well almost unheard of, anyway. Last April, massive amounts of beetles laid siege to residential and urban areas of Bullhead City. The worst aspect of this invasion was the foul-smelling defensive fluids that the beetles secrete when they become threatened or when they are squished.

Last spring, residents of Bullhead City could not help but notice the abundance of beetle corpses and live beetles littering parking lots, residential lawns, parks and busy streets. Many of the beetles found their way indoors, and the ones that didn’t rapidly succumbed to dehydration. According to one pest control expert, all the beetles that had been found in the city resulted from unusually high moisture levels that persisted since the beginning of the year in the northwest region of Arizona. The frequent bouts of rain during the winter and the consequent overgrowth of vegetation during the spring caused the beetles to invade the city en masse.

Employees at a local Ace Hardware store removed both dead and live beetles from the area surrounding the store for weeks. Thousands of beetles could be seen outside Kohl’s and Target where corpses became so abundant that the parking lot became slippery in some places. Many dogs and cats in the city quickly learned that the beetles make for a lousy meal, as several pet owners claimed that their dog or cat quickly spat a beetle out quickly after collecting it from the ground. The reason the pets did this is due to this particular beetle species’ defensive secretions. The beetles in question are known as “desert stink beetles” in Arizona, as the beetles are well known to gather around outside lights during the spring, summer and fall. The defensive fluid secreted by these beetles causes intolerable irritation, providing these beetles with an ideal way to avoid being eaten alive.

Have you ever caught a whiff of smelly odors secreted by insects?

Millipedes Can Invade Arizona Homes Where They Sometimes Spray A Painful And Irritating Compounds Onto Human Skin

Millipedes Can Invade Arizona Homes Where They Sometimes Spray A Painful And Irritating Compounds Onto Human Skin

Many Arizona residents have likely encountered large and intimidating centipedes within rural and suburban habitats, and few residents have managed to avoid encounters with common house centipedes. Millipedes look similar to centipedes and they are commonly spotted within urban, rural and residential yards. It is not uncommon for millipedes to infest homes in Arizona in large numbers. Once millipedes enter homes in the state they often gravitate to dark corners where residents often sustain chemical burns from millipede secretions. The millipede species, Orthoporus ornatus, has probably been encountered around homes, in parks or just about any natural environment where soil can be found. The common Orthoporus ornatus millipede species, which is more commonly referred to as the “desert millipede,” is also considered a household pest in Arizona, and it is not uncommon for residents to sustain chemical burns after accidentally or deliberately making contact with these arthropods within and near homes.

The desert millipede is often found within residential yards in large numbers following storms during monsoon season, and these millipede pests often move into homes where internal moisture levels can sustain the species. An abundance of vegetation growth alongside foundations provide moist conditions that are ideal for desert millipedes and once large number become established around a home’s foundation, preventing the millipedes from moving indoors can be difficult. Millipedes may also feed on ornamental and garden flowers, but the damage they inflict to these aesthetically appreciated plants is usually minimal, even within yards that become highly infested. This species favors cholla, creosote bush, ocotillo, and mesquite forms of decaying plant material for feeding purposes. The desert millipede often curls its 6 inch long body into a coil in response to threats. Unfortunately, this US millipede species is unique for its ability to spray a painful toxic secretion as far as ten feet within a home. If this secretion makes contact with the eyes, partial or complete blindness can result. This species toxic defensive secretion contains benzoquinones, aldehydes, hydrocyanic acid, phenols, terpenoids, nitromethylbenzene, and other substances. However, serious burns and skin discoloration resulting from skin contact with this millipede’s sections are rarely reported, and in many cases, Arizona residents keep them as pests.

Up To 4,000 Scorpion Stings Are Reported In And Around Phoenix Every Year, And Some Arizona Residents Are More Likely To Sustain A Sting Than Others

Up To 4,000 Scorpion Stings Are Reported In And Around Phoenix Every Year, And Some Arizona Residents Are More Likely To Sustain A Sting Than Others

Thirty scorpion species can be found in Arizona, and more species may have yet to be discovered within the state. This may be a bold statement, as one would think that all scorpions within Arizona have certainly been discovered by now. However, a new species, Vaejovis crumpi, was discovered in Prescott in 2011, and much of Arizona is uninhabited desert, making the existance of additional undocumented species a distinct possibility in the state. It is comforting to know that all potentially dangerous scorpion species in Arizona have likely been found, as a few scorpion species already inflict medically significant stings to thousands of Arizona residents annually. Surprisingly, between 3,000 and 4,000 scorpion stings occur annually within the Phoenix metropolitan area alone. Researchers have noted that scorpion stings are not evenly distributed across metropolitan areas in Arizona, making residents of Phoenix more likely to sustain scorpion stings than others.

The desert hairy scorpion, the devil scorpion and the bark scorpion are the three most commonly encountered scorpion species within Arizona. While the desert hairy scorpion may be the most intimidating species to look at given their 5 to 6 inch body length, this species is not considered medically significant, but the much smaller 3 inch bark scorpion can inflict potentially deadly stings. The risk of falling victim to a scorpion sting is remote within urbanized locations found where concrete sidewalks, buildings and business are abundant, but unsurprisingly, the risk of sustaining a scorpion stings is much greater in suburban regions. This makes most apartment dwellers relatively safe from scorpion stings, but the residents living within single family homes located near open and undeveloped landscapes are at the greatest risk of sustaining a scorpion sting in Arizona. Unlike apartments and townhouses, single family homes are isolated structures. Homes in these regions are also far more likely than others to become infested with scorpions. Residents living in these areas should be mindful of scorpions on their lawn during the night hours, as all scorpions are nocturnal.

When Cockroaches Bite And Invade The Human Body

Indoor spider, centipede, ant, flea, beetle or bed bug infestations can be nightmarish for homeowners, but few arthropod pest species are considered to be more revolting than cockroaches. Unfortunately, cockroaches are among the most commonly encountered indoor insect pest species in the world. In fact, one study that aimed to identify the most common indoor arthropod species found cockroaches within 74 percent of 50 homes surveyed. Although a mere 50 homes may not provide an accurate representation of all homes located in every state in the US, the study’s authors stated that several follow-up studies conducted in a variety of regions around the globe yielded similar results. One particular anecdotal report describes a married couple’s surprise upon learning that cockroaches are just as common within their new Phoenix home as they were within their many former homes located in their hometown of Chicago.

While cockroaches are undoubtedly well established within just about every home in the world, at least people can take solace in the fact that cockroaches don’t bite or establish horrifying bodily infestations like chiggers, and certain species of mites and fly larvae. Well, to be perfectly accurate, there is an extremely slim chance that cockroaches will, one day, make a home inside of your body. Unfortunately, it is indeed true that many medical case reports describe instances involving cockroaches crawling into human body cavities.

Cockroaches are generally nuisance pests within homes, but the insects have been documented as causing human disease by spreading pathogens within homes and buildings, but such cases are rare. It is even more rare for cockroaches to climb within a human ear, nose, mouth or other bodily cavity where they maintain a lasting presence, but numerous medical cases describing such instances are not hard to come by. The vast majority of bodily roach infestations occurred after the insects crawled into body cavities at night while the victims had been sleeping, which also happens to be the same time that indoor cockroaches become active, as most species are nocturnal. Some cases saw several roaches invade the intestines of young children that had been living within severely infested conditions. Unfortunately, medical experts claim that such cases occur due to the above mentioned circumstances, and as it happens, roaches find earwax appetizing. So consider earplugs before falling asleep at night.

Have you ever heard of any incident involving arthropod infestations within human bodies?

Repeat Fly Invasions Within A Phoenix Healthcare Facility Caused Maggots To Take Form Within A Patient’s Wound

Repeat Fly Invasions Within A Phoenix Healthcare Facility Caused Maggots To Take Form Within A Patient’s Wound

Not long ago, Arizona lawmakers passed a law requiring all intermediate healthcare facilities in the state to be licensed. A recent and deplorable insect infestation case at Hacienda HealthCare in Phoenix proves that this law was most certainly in order, as a patient in the facility was found to be literally infested with maggots. The maggots were found nesting within an existing wound on the body of a 28 year-old male patient. In response to this disturbing find, the Arizona Department of Health Services has issued an intent to revoke the facility’s license.

The health services department has accused Hacienda HealthCare as providing grossly inadequate care to its patients. Officials claimed that immediate action is necessary in order to protect patients within the facility from neglect that could possibly result in worsening medical conditions. The maggots were found after a respiratory therapist at the facility found 6 to 12 maggots beneath the patient’s wound dressing. Staff working at the facility claimed that the maggots probably resulted from the patient’s alleged “poor hygiene,” needless to say, this claim was not received well considering the facility’s lengthy record of inadequate patient care. The spokesperson, David Liebowitz further claimed that a “small number” of maggots were found in the man’s wound on wednesday and then a few more were found on thursday. In other words, the presence of maggots in the patient’s wound went ignored by the staff. However, Liebowits also claimed that maggots have not been found on any other patients in the facility.

Despite the purported cause of the maggot infestation as resulting from the victim’s poor hygiene, the department of health quickly learned that several pest control professionals have been in and out of the facility for weeks in an effort to control a fly infestation. Flies had become a problem in the facility due to the installation of blower fans which allowed the flies easy access into the facility. Ironically, the fans that were being installed are meant to prevent flies and other airborne insects from entering the facility. Liebowitz later stated that the maggot presence in the man’s wound was caused by the fly infestation.

Have you ever heard of flies placing their eggs within human body cavities or wounds?

How Many Widow Spiders Exist In Arizona

While black widow spiders are well known for inflicting painful and medically significant bites to humans, the spiders are not well understood by the public. This is true even in Arizona where the highly venomous spiders can be found on occasion within homes. Internet sites happen to be one of the most significant sources of disinformation concerning black widow spiders. For example, a quick Google search will tell you that “22 types” of black widows can be found just within the city limits of Phoenix and Tucson. However, the United States is home to only 3 “black widow” species, while only one single black widow species, not 22, can be found within the state of Arizona. This species is known as Latrodectus hesperus, or the western black widow, as it is more commonly called. It should also be noted that black widows are categorized in the genus Latrodectus, also known as “widow spiders.” In all, only two widow spider species can be found in Arizona. The other species being the recently introduced “brown widow.”

Black widows are often considered their own species because all three species in the US are referred to by the same common name. These three species are commonly known as southern black widows, western black widows, and northern black widows. Both southern and northern black widows can be found in the eastern half of the US. The southern variety is most often found in areas east of Texas and up north to Virginia, while the northern black widow’s habitat is largely limited to the entire eastern seaboard and into parts of the midwest. The western black widow can be found along the west coast, particularly in the desert southwest. In addition to the western black widow species, another widow species that is not native to the US has been found along the southernmost border of the country. This species is commonly referred to as the brown widow, and it is not known to many residents of Arizona because it has only recently been found in the state. The brown widow was most likely introduced accidentally into the region via shipments of plant matter. Finally, the red widow is a species that can only be found in southern Florida. So far, a total of 31 widow species have been found worldwide.

Have you ever spotted a western black widow within your home? Were you  aware that a non-native widow spider species exists within Arizona?
