WThe Australian cockroach is a common species of tropical cockroach, with a length of 23–35 mm (0.91–1.38 in). It is brown overall, with the tegmina having a conspicuous lateral pale stripe or margin, and the pronotum with a sharply contrasting pale or yellow margin. It is very similar in appearance to the American cockroach and may be easily mistaken for it. It is, however, slightly smaller than the American cockroach, and has a yellow margin on the thorax and yellow streaks at its sides near the wing base.
WCallosobruchus maculatus is a species of beetles known commonly as the cowpea weevil or cowpea seed beetle. It is a member of the leaf beetle family, Chrysomelidae, and not a true weevil. This common pest of stored legumes has a cosmopolitan distribution, occurring on every continent except Antarctica. The beetle most likely originated in West Africa and moved around the globe with the trade of legumes and other crops. As only a small number of individuals were likely present in legumes carried by people to distant places, the populations that have invaded various parts of the globe have likely gone through multiple bottlenecks. Despite these bottlenecks and the subsequent rounds of inbreeding, these populations persist. This ability to withstand a high degree of inbreeding has likely contributed to this species’ prevalence as a pest.
WChelifer cancroides, the house pseudoscorpion, is a species of pseudoscorpions. It is a cosmopolitan, synanthropic, and harmless species to humans.
WChelisoches morio, commonly known as the black earwig, is a cosmopolitan earwig in the family Chelisochidae. Black earwigs are active at all times of the day, and prefer wet habitats. Adults can grow up to 36 millimetres (1.4 in).

WCopidosoma floridanum is a species of wasp in the family Encyrtidae which is primarily a parasitoid of moths in the subfamily Plusiinae. It has the largest recorded brood of any parasitoidal insect, at 3,055 individuals. The life cycle begins when a female oviposits into the eggs of a suitable host species, laying one or two eggs per host. Each egg divides repeatedly and develops into a brood of multiple individuals, a phenomenon called polyembryony. The larvae grow inside their host, breaking free at the end of the host's own larval stage.

It is the most widely distributed syrphid species in the world and is known from all regions except the Antarctic. It has been introduced into North America and is widely established. It can be found in gardens and fields in Europe and Australia. It has also been found in the Himalayas.
WFannia scalaris, also known as the latrine fly, is a fly species in the Fanniidae family. This species is smaller and more slender than the house fly, Musca domestica, and is similar in appearance to the lesser house fly, Fannia canicularis. The life cycle of this species can be as long as one month. These flies are globally distributed in urban areas as they are drawn to unsanitary environments. F. scalaris is a major cause of myiasis, the infestation of a body cavity by fly maggots. The adults infest bodies that have decomposed, making the species an important part of forensic entomology. The larvae of this fly have adapted protuberances, or feathered appendages, that allow them to survive in such a moist environment. Entomologists continue to research the effects that F. scalaris may have medically, forensically, and on the environment around them.
WHouse dust mites are mites found in association with dust in dwellings. They are known for causing an allergy.
WThe housefly is a fly of the suborder Cyclorrhapha. It is believed to have evolved in the Cenozoic Era, possibly in the Middle East, and has spread all over the world as a commensal of humans. It is the most common fly species found in houses. Adults are gray to black, with four dark, longitudinal lines on the thorax, slightly hairy bodies, and a single pair of membranous wings. They have red eyes, set farther apart in the slightly larger female.
WLabidura riparia is a species of earwig in the family Labiduridae characterized by their modified cerci as forceps, and light tan color. They are commonly known as the shore earwig, tawny earwig, riparian earwig, or the striped earwig due to two dark longitudinal stripes down the length of the pronotum. They are sometimes wrongly referred to as Labidura japonica, although said species is actually a subspecies, Labidura riparia japonica, found only in Japan. L. riparia are a cosmopolitan species primarily in tropical to subtropical regions. Body size varies greatly, ranging from 16 mm to 30 mm, with 10 abdominal segments. Males and females differ in forcep size, with males having much larger and stronger curve, while females have smaller, straighter forceps with a slight curve at the end. Earwigs use these forceps to assist in predation, defense, sexual selection, courting and mating, and wing folding.
WLepas anatifera, commonly known as the pelagic gooseneck barnacle or smooth gooseneck barnacle, is a species of barnacle in the family Lepadidae. These barnacles are found, often in large numbers, attached by their flexible stalks to floating timber, the hulls of ships, piers, pilings, seaweed and various sorts of flotsam.
WLepidurus apus, commonly known as a tadpole shrimp, is a notostracan in the family Triopsidae, one of a lineage of shrimp-like crustaceans that have had a similar form since the Triassic period and are considered living fossils. This species is cosmopolitan, inhabiting temporary freshwater ponds over much of the world, and the most widespread of the tadpole shrimps. Like other notostracans, L. apus has a broad carapace, long segmented abdomen, and large numbers of paddle-like legs. It reproduces by a mixture of sexual reproduction and self-fertilisation of females.
WLinguatula serrata is a cosmopolitan zoonotic parasite, belonging to the tongueworm order Pentastomida. They are wormlike parasites of the respiratory systems of vertebrates. They live in the nasopharyngeal region of mammals. Cats, dogs, foxes, and other carnivores are normal hosts of this parasite. Apparently, almost any mammal is a potential intermediate host.
WAnisolabis maritima, commonly known as the maritime earwig or the seaside earwig, is a species of earwig in the family Anisolabididae. Similar to the seashore earwig, this species can be found near the shore line, and is cosmopolitan. It can be found in almost all biogeographic realms. Scientists believe that these earwigs originally came from Asia. Since then, however, they have been introduced to North America, and have now spread around the world due to international commerce.

WSarcoptes scabiei or the itch mite is a parasitic mite that burrows into skin and causes scabies. The mite is found in all parts of the world. Humans are not the only mammals that can become infected. Other mammals, such as wild and domesticated dogs and cats as well as ungulates, wild boars, bovids, wombats, koalas, and great apes are affected.
WThe Sphecidae are a cosmopolitan family of wasps of the suborder Apocrita that includes sand wasps, mud daubers, and other thread-waisted wasps.
WThe Surinam cockroach or greenhouse cockroach is a species of burrowing cockroach. It is a common plant pest endemic to the Indomalayan realm that has spread to tropical and into subtropical regions around the world, and in isolated populations to temperate climates where protective habitat such as greenhouses provide shelter for individuals inadvertently shipped in the soil of plants. Its populations are almost exclusively female, and it reproduces through parthenogenesis, having evolved several clonal strains from its sexual progenitor P. indicus.
WTenebroides mauritanicus, commonly known as the cadelle, is a cosmopolitan and common pest in storehouses and granaries. Adults and larvae feed on grain and grain products, predate upon other insects infesting grain, and bore into wood. They typically pupate in wood cavities that they make. It is one of the longest lived insects that attacks stored grain and is very destructive and easily dispersed. It is also one of the largest.
WTyphaea stercorea is a cosmopolitan species of beetle of the family Mycetophagidae, known by the common name hairy fungus beetle.
WTyrophagus putrescentiae is a cosmopolitan mite species. Together with the related species T. longior, it is commonly referred to as the mould mite or the cheese mite. The name translates from Greek to something like "putrid cheese eater."
WThe wharf borer, Nacerdes melanura, belongs to the insect order Coleoptera, the beetles. They belong to the family Oedemeridae, which are commonly known as false blister beetles. Wharf borers are present in all the states of the USA except for Florida. It takes about a year to develop from an egg to an adult. The insect is called the 'wharf borer' because the larval stage of this insect is often found on pilings and timbers of wharves, especially along coastal areas. The adult beetles can be identified via a black band across the end of both elytra, or wing covers. In addition, wharf borers can be distinguished from other members of the family Oedemeridae via the presence of a single spur on the tibia of the forelegs, and the distance between both eyes. Eggs are oviposited on rotten wood where larvae hatch and burrow to feed on rotten wood. Adults do not feed and depend on stored energy reserves accumulated during the larval stage. They are considered to be a pest because they damage wood used in building infrastructures.
