How Often Do Arizona Pest Control Professionals Address Harvester Ant Infestations That Pose A Medical Threat To The Occupants Of Infested Homes?

How Often Do Arizona Pest Control Professionals Address Harvester Ant Infestations That Pose A Medical Threat To The Occupants Of Infested Homes?

It is probably safe to say that most Arizona residents are aware that numerous venomous and medically threatening animals inhabit their home state, including snakes, spiders, scorpions, ants, wasps, bees, and even lizards. It is also common knowledge that virtually all spiders in the state, while venomous and intimidating to look at, are harmless to humans. Of course, the western black widow and a few recluse spider species are exceptions in this regard. In Arizona, bees are more deadly than snakes, and this is due to the abundance of Africanized honey bees (killer bees) in the state. The Arizona bark scorpion has the potential to inflict deadly bites, but quality medical care makes fatal scorpion stings unheard of in the southwest US. Many Arizona residents are under the impression that red-imported fire ants can be found near their homes, but these hazardous ants were actually eradicated from the state years ago. However, extremely venomous harvester ants are abundant around Arizona homes.

The stings inflicted by harvester ants are considered to be among the most painful, and the venom produced by these ants is more toxic than that of all other insect species documented. A little more than 24 harvester ant species have been documented in North America, most of which can be found in Arizona. Studies have shown that southern fire ants and multiple harvester ant species are responsible for the vast majority of medically significant ant stings that occur in Arizona. The three harvester ant species considered to be a public health threat in Arizona are commonly known as rough, red and Maricopa harvester ants. The red harvester ant has caused two documented deaths. In one case, a Tucson man went into anaphylactic shock after one single red harvester ant stung his upper thigh. Apparently, the ant crawled into the man’s shorts while he had been sitting on a sidewalk.

Harvester ants are considered medically threatening pests due to their abundance in urban and suburban areas of Arizona, particularly Phoenix and Tucson. Luckily, harvester ants are not likely to invade homes, but one study found that Arizona pest control companies address harvester ant infestations frequently. In fact, harvester ant infestations around Arizona homes are becoming increasingly common due to the rate at which new homes are being built in their desert habitat.

Have you ever had an encounter with harvester ants?

The Little-Known Ant Pests That Commonly Nest In Woodwork And Inflict Painful Bites

The Little-Known Ant Pests That Commonly Nest In Woodwork And Inflict Painful Bites

The Crematogaster genus is comprised of numerous ant species, many of which are considered biting and wood-damaging structural pests. Worker ants from this genus vary from 2.5 mm to 4 mm, and their unusually large heads make them somewhat recognizable. Their heads range in color from reddish-brown to black, and most species possess dark or black colored bodies. Crematogaster ants rarely nest in soil below the ground; instead, these ants prefer to establish nests in moisture-damaged wood sources above the ground, most notably within tree stumps, logs, posts, and at the base of dead and decaying trees. Occasionally, these establish nests in moist structural wood within homes, and they are particularly abundant in urban and suburban habitats where multiple Crematogaster species are known pests that are commonly referred to as “acrobat ants,” and “cocktail ants.” These common names derive from their strange habit of raising or “cocking” their gaster (bulbous rear body segment) above their head when they become threatened.

Due to their need for moisture, Crematogaster ants are most abundant in the humid southeast, but several Crematogaster species can be found throughout Arizona, including the two most pestiferous species, C. cerasi and C. lineolata. C. cerasi workers are reddish-brown and they frequently nest within wood on roofs, wood siding, structural wood in ceiling and wall voids, door and window frames, and wooden porches. Workers are known for being aggressive and they emit an unpleasant odor when disturbed. C. lineolata workers are the same color as C. cerasi workers, with the exception of some yellowish colored individuals. Like most species in this genus, C. lineolata workers emit a foul odor when disturbed, but unlike many of their close relatives, C. lineolata workers aggressively bite humans. While C. cerasi prefers to feed on live and dead insects, C. lineolata workers seek out human food sources, especially sweets and meat, making them common within pantries and kitchen cupboards. Both species tend to establish nests within existing cavities in wood that had already been excavated by other insect species, such as termites and carpenter ants.

The Very Common Indoor Ant Pest That Is Often Mistaken For The Argentine Ant

The Very Common Indoor Ant Pest That Is Often Mistaken For The Argentine Ant

One of the most common ant pest species in southern Arizona, Iridomyrmex pruinosus, or Forelius pruinosus, as the species is known today, is often mistaken for the highly pestiferous Argentine ant species. Argentine ants are common ant pests in most southern states, but they are relatively less abundant in Arizona. F. pruinosus, on the other hand, is consistently the first or second most commonly encountered ant species by pest control professionals in residential areas of Phoenix. This pest species is also among the top 5 most commonly encountered ant pest species in residential areas of Tucson. While this ant pest does not inflict venomous stings to humans, F. pruinosus workers invade homes in large numbers, and eradicating infestations is exceedingly difficult, even for professionals.

DYI pest control techniques will usually not suffice to eliminate F. pruinosus infestations, and most infestation victims do not bother with such techniques after seeing the overwhelming number of ants an infestation entails. Although F. pruinosus colonies are not as large as Argentine ant colonies, the former occasionally nests within houses, while the latter sees workers invade homes from outside nests. In most F. pruinosus infestation cases, the workers invade homes from nests located near the foundation and at the surface of soil beneath concrete slabs. Nests are also frequently found in exposed soil and obscured beneath objects like stones, leaf litter, patios, wood piles, logs, and around stumps. This species is abundant throughout the southeast and in much of the southwest, but specimens collected from these two areas look markedly different from one another. Southeastern species are usually dark, while southwestern species see workers come in a variety of shades and colors, but most are light in color. Workers are relatively small at only around 1.8 to 2 mm in length regardless of their geographic location, and they form uniform foraging trails that lead into homes from outside nests. When crushed, F. pruinosus secrete a fluid that smells strongly of rotten coconut, not unlike the odor produced by the aptly named odorous house ant species.

Have you ever experienced an infestation that consisted of an unusually large number of ant pests?

Which Ant Pests Are Able To Establish Colonies Within Arizona Homes?

Several insect species in Arizona are considered pests within human dwellings, but not all insect pest species in the state are able to survive and reproduce within homes for indefinite periods of time. This is the case when it comes to seasonal insect house pests, such as boxelder bugs, elm leaf beetles, and cluster flies. These insect pests invade homes in large numbers during the fall in order to overwinter, but they are unable to reproduce indoors, and unless they eventually re-establish an outdoor presence, they will perish within homes. However, the most common and pestiferous insect pests commonly found in Arizona homes, like cockroaches, termites, house flies, bed bugs, carpet beetles, and many ant species, establish reproductive populations indoors. These insect pests are able to establish lasting indoor infestations that can be difficult to eradicate.

Some of the most common ant pests in Arizona that are able to establish indoor nests that contain reproductive queens include southern fire ants, thief ants and carpenter ants. Most indoor nesting ant pests species, such as southern fire ants and carpenter ants, can only establish thriving indoor colonies if they establish nests within moist areas. Unlike southern fire ants, carpenter ants establish nests within moist structural wood within homes, but just like southern fire ants, carpenter ants usually establish nests outside of wood within moist wall voids in bathrooms, around plumbing and near water heaters. These two pests also feed on indoor food sources. Of course, indoor thief ants must also be well hydrated in order to thrive within homes, but these pests tend to nest indoors in order to regularly feed on a variety of human food sources. These food sources include meats, cheeses and grease. While all these ant pests, and the majority of others, are able to nest indoors, they may also nest within soil and damp tree hollows located near the foundation of homes. In these cases, ant pests enter homes from outside nests solely to seek water and human food sources.

Velvety Tree Ants Are Nuisance Pests That May Damage A Home’s Structural Wood And Inflict Bites

The velvety tree ant is one of many nuisance ant pest species commonly found around and within Arizona homes. These ants establish nests within dead wood sources that have become decayed or waterlogged. This species’ most common nesting sites are located within tree stumps, dead trees, isolated logs, beneath the bark of living trees, and within soil located beneath dead wood. These ants have also been known to nest within structural and cosmetic wood sources, especially in damaged structural wood that makes contact with the ground soil. While velvety tree ants do not feed on structural wood like termites do, they can cause further damage to structural and cosmetic wood sources that have already become compromised by rainwater, plumbing leaks or lawn irrigation. Velvety tree ants may also infest yards where they build an extensive network of foraging trails below and above the ground. Although these ants do not sting, they may bite when disturbed.

In addition to nesting within damaged structural and cosmetic wood sources, velvety tree ants may also establish centralized nesting sites within decayed natural wood sources located on residential lawns. These ants sometimes become abundant near or alongside structural foundations where the pests can easily invade indoor areas in large numbers. Reproductive swarmers emerge from colony nesting sites every summer, and these swarms have been known to emerge from infested structural wood within homes. The nests that these ant pests excavate within wood resembles a honeycomb, and workers venture back and forth between the nest and the outside environment where they prey upon honeydew-rich aphids and other insects. Velvety tree ants feed on a variety of human foods as well, which may attract large numbers of worker ants into indoor living areas, particularly kitchens and pantries.

Black to brown colored velvety tree ant workers range from ⅛ to ¼ of an inch in length, and they are often confused with odorous house ants due to their similar indoor foraging habits, appearance and for the unpleasant odor that workers emit when they become threatened or crushed. Velvety tree ants are also frequently confused with carpenter ants due to their habit of nesting within decayed structural and cosmetic wood within homes.

Have you ever found ants congregating in your cupboard or pantry?

The Native Southern Fire Ant Is An Aggressive Species That Inflicts Painful Stings And Infests Homes, And At Least One Envenomation Incident Resulted In Death

The Native Southern Fire Ant Is An Aggressive Species That Inflicts Painful Stings And Infests Homes, And At Least One Envenomation Incident Resulted In Death

The S. xyloni ant species is one of three fire ant species found in Arizona, the others being S. aureus and S. amblychila. The red-imported fire ant is the most well known fire ant species in the United States, and while this species is invasive in the US, many people are surprised to learn that some fire ants are native to the US, one of which is the S. xyloni species. The S. xyloni fire ant species is commonly referred to as the “southern fire ant,” and this species can be recognized by their dark reddish-brown exterior that is covered in golden hairs.

Like other fire ant species, the southern fire ant often inflicts damage to lawns which can sometimes be costly for homeowners. When fire ants infest a lawn their unsightly dirt mounds become a conspicuous part of the landscape, and southern fire ant nests can also become established indoors. Much like red imported fire ants, southern fire ants will emerge out of their nests in large numbers if they become distrubed. These ants will not hesitate to climb onto a person’s body before inflicting numerous stings, which can be fatal to those with an allergy to arthropod venoms. These ants can also establish indoor infestations that can pose both a medical risk to a home’s inhabitants as well as a nuisance. The southern fire ant prefers to establish colonies within lawns where grass is stressed and dry, making them a prominent species in southern Arizona. This species can also establish nests within wall-voids, below carpeting, and in crawl spaces, and colonies can grow to contain 10,000 individual ants. While anaphylaxis does not often occur in response to southern fire ant stings, this species was believed to have caused the death of a three month old baby after the ant pests invaded a day care center.

Have you ever experienced a fire ant infestation either indoors or outdoors?

Fire Ants Spread Around The Globe Via Spanish Galleons Over Four Hundred Years Ago

The transport of insects to regions where they are not native is a serious problem in today’s world. Not surprisingly, this problem has existed ever since mankind took to the seas. When Columbus, and early European settlers in America first traveled across the Atlantic, they probably did not anticipate upsetting the balance of the world’s ecosystems, but this is exactly what has occurred as a result of maritime travel. Although customs officials and other authorities do their best to prevent the accidental transport of insects into non-native regions today, the fact is that invasive insects are increasing. Fire ants happen to be one of the earliest known insects to be transported to regions all over the globe via maritime travel. There may have been numerous other insect species that had been transported to non-native regions before fire ants, but fire ants were the first insect species to establish a global habitat as a result of careless sea travel. Many insects likely die as a result of being ill suited to new environments, but the durable fire ant has endured in just about every non-native habitat where they have been introduced.

During the sixteenth century, Spanish ships accidentally transported fire ants from the Americas to other regions across the sea. Fire ants had always been native to the Americas, but thanks to early colonial travel, fire ants have established habitats in every location that is either tropical or subtropical. The early transport of fire ants allowed people from all over the world to experience their extremely painful bites for themselves. Researchers recently published a study in the Journal of Molecular Entomology that describes how fire ants established their invasive habitat hundreds of years ago.

The manner in which fire ants spread in the sixteenth century will amaze you, as early maritime travelers seemed to be trying to spread as many insects across the globe as they could. Back then, when a ship would dock at a port, the crew would fill the ship’s ballast with soil only to later transfer and dump the soil at another port in a foreign country. Once the soil was dumped, its weight would be replaced with cargo. Of course, early sea travelers were simply ignorant of the consequences of transporting soil to different parts of the world. However, if they had known that they were moving enormous amounts of insects within the soil, they may not have stopped, as the negative environmental consequences of this insect transport were not known to most people at the time.

Do you think that enough precautions are taken today to prevent the global spread of insects by means of maritime travel?

Magic Pest Control offers prevention tips for homeowners to avoid ant problems

Spotting a line for food at a summer barbeque can be exciting, but not when it’s accompanied with a line of ants. Magic Pest Control says prevention of these picnic-crashing pests is key because they can be difficult to control once they infiltrate a property in large numbers.

Summer cookouts, and the crumbs they leave behind, are the perfect targets for ants in need of food and water. There are, however, quick tips and tricks that homeowners can use to sidestep ant infestations. These simple efforts can go a long way, as ants can contaminate food and colony sizes can be quite large depending on the species.

  • Eliminate sources of moisture or standing water; repair leaky pipes or faucets.
  • Quickly clean up crumbs and spills as soon as possible.
  • Do the dishes, wipe down counters, tabletops, sweep up floors and remove trash regularly.
  • Don’t leave leftover dog and cat food dishes sitting out all day; pick up dishes once the animals are done eating.
  • Check under appliances and behind garbage cans where crumbs and residue can accumulate.
  • Keep tree branches and other plants cut back from the house.
  • Seal any cracks or small openings around the foundation of the home and repair ripped screens as these can serve as entry points.
