Bedbug
Bed bugs are parasitic insects from the genus ''Cimex'', which are micropredators that feed on blood, usually at night. Their bites can result in a number of health impacts, including skin rashes, psychological effects, and allergic symptoms. Bed bug bites may lead to skin changes ranging from small areas of redness to prominent blisters. Symptoms may take between minutes to days to appear and itchiness is generally present. Some individuals may feel tired or have a fever. Typically, uncovered areas of the body are affected. Their bites are not known to transmit any infectious disease. Complications may rarely include areas of dead skin or vasculitis. Bed bug bites are caused primarily by two species of insects: ''Cimex lectularius'' (the common bed bug) and ''Cimex hemipterus'', found primarily in the tropics. Their size ranges between 1 and 7 mm. They spread by crawling between nearby locations or by being carried within personal items. Infestation is rarely due t ...

Cimex
''Cimex'' is a genus of insects in the family Cimicidae. ''Cimex'' species are ectoparasites which typically feed on the blood of birds and mammals. Two species, ''Cimex lectularius'' and ''Cimex hemipterus'', are known as bed bugs and frequently feed on humans, although other species may parasitize humans opportunistically. Species primarily parasitizing bats are known as bat bugs. The insects are long and have flattened reddish-brown bodies with small nonfunctional wings. Description Adult ''Cimex'' are light brown to reddish-brown, flat and oval. The mouthparts are beak-like, and adapted for piercing and sucking. Following a blood meal the abdomen is plump and darker in colour. The front wings are Vestigiality, vestigial and reduced to pad-like structures. ''Cimex'' lacks hind wings. They have segmented abdomens with microscopic hairs that give them a banded appearance. Adults grow to long. The different species are very similar in Morphology (biology), morphology and ca ...

Bed Bug Eradication
Bed bugs, or Cimicidae, are small parasitic insects. The term usually refers to species that prefer to feed on human blood. Early detection and treatment are critical to successful control. According to a survey, the most commonly infested places are the mattress (98.2%), boxspring (93.6%), as well as nearby carpets and baseboards (94.1%).Gangloff-Kaufmann, J.C. et al. 2006 Bed bugs in America: a pest management industry survey. Am. Entomol. 52: 105–106 In fact, bed bugs thrive in areas where there is an adequate supply of available hosts, and plenty of cracks and harborages within of the host. Because treatments are required in sleeping areas and other sensitive locations, methods other than chemical pesticides are in demand. Treatments can be costly, laborious, time consuming, repetitive, and embarrassing, and may entail health risks.

Cimex Hemipterus
''Cimex hemipterus'', known as the tropical bed bug, is a species of bed bugs within the family Cimicidae that primarily resides in tropical climates. However, it has been reported that this species can live in more temperate climates along with the closely related bed bug species '' C. lectularius.'' ''C. hemipterus'' is a hematophagous, obligate parasite of humans. This means that it requires blood meals from their human hosts in order to survive. When bitten, humans experience itchiness, wheals, and lesions around the affected areas on the skin. This species typically resides in human domiciles within cracks, crevices, or mattresses, and are more prevalent in developing countries. Like other bed bugs, ''C. hemipterus'' is primarily active during the night time. Morphology On average, ''C. hemipterus'' is 5.5 millimeters long and 2.5 millimeters wide. This insect has an ovular and flattened body shape. Its head is short, broad, and pointed at the tip. The rounded, black or ...

Haematophagy
Hematophagy (sometimes spelled haematophagy or hematophagia) is the practice by certain animals of feeding on blood (from the Ancient Greek, Greek words αἷμα ' "blood" and φαγεῖν ' "to eat"). Since blood is a fluid tissue rich in nutritious proteins and lipids that can be taken without great effort, hematophagy is a preferred form of feeding for many small animals, such as worms and arthropods. Some intestinal parasitic worm, nematodes, such as Ancylostomatidae, Ancylostomatids, feed on blood extracted from the Capillary, capillaries of the gut, and about 75 percent of all species of leeches (e.g., ''Hirudo medicinalis'') are hematophagous. The spider ''Evarcha culicivora'' feeds indirectly on vertebrate blood by specializing on blood-filled female mosquitoes as their preferred prey. Some fish, such as lampreys and Candiru (fish), candirus; mammals, especially vampire bats; and birds, including the vampire finch, Hood mockingbird, Tristan thrush, and oxpeckers, al ...

Infestation
Infestation is the state of being invaded or overrun by pests or parasites. It can also refer to the actual organisms living on or within a host. Terminology In general, the term "infestation" refers to parasitic diseases caused by animals such as arthropods (i.e. mites, ticks, and lice) and worms, but excluding (except) conditions caused by protozoa, fungi, bacteria, and viruses, which are called infections. External and internal Infestations can be classified as either external or internal with regards to the parasites' location in relation to the host. External or ectoparasitic infestation is a condition in which organisms live primarily on the surface of the host (though porocephaliasis can penetrate viscerally) and includes those involving mites, ticks, head lice and bed bugs. An internal (or endoparasitic) infestation is a condition in which organisms live within the host and includes those involving worms (though swimmer's itch stays near the surface). Somet ...

Micropredator
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites' way of feeding as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), ...

Cimex Lectularius
''Cimex lectularius'', or the common bed bug, is a species of Cimicidae. Its primary hosts are humans, and it is one of the world's major "nuisance pests." Although bed bugs can be infected with at least 28 human pathogens, no studies have found that the insects are capable of transmitting any of these to humans. They have been found with methicillin-resistant ''Staphylococcus aureus'' (MRSA) and with vancomycin-resistant ''Enterococcus faecium'' (VRE), but the significance of this is still unknown. Investigations into potential transmission of HIV, MRSA, hepatitis B, hepatitis C, and hepatitis E have not shown that bed bugs can spread these diseases. However, there is some evidence that arboviruses may be transmissible. Bed bug bites or cimicosis may lead to a range of skin manifestations from no visible effects to prominent blisters. Effects include skin rashes, psychological effects, and allergic symptoms. Occurrence and distribution ''Cimex lectularius'' is found ...

Dermatitis Herpetiformis
Dermatitis herpetiformis (DH) is a chronic autoimmune blistering skin condition, characterised by intensely itchy blisters filled with a watery fluid. DH is a cutaneous manifestation of coeliac disease, although the exact causal mechanism is not known. DH is neither related to nor caused by herpes virus; the name means that it is a skin inflammation having an appearance (Latin: '' -formis'') similar to herpes. The age of onset is usually about 15 to 40, but DH also may affect children and the elderly. Men are slightly more affected than women. Estimates of DH prevalence vary from 1 in 400 to 1 in 10,000. It is most common in patients of northern European and northern Indian ancestry, and is associated with the human leukocyte antigen (HLA) haplotype HLA-DQ2 or HLA-DQ8 along with coeliac disease and gluten sensitivity. Dermatitis herpetiformis was first described by Louis Adolphus Duhring in 1884. A connection between DH and coeliac disease was recognized in 1967. Signs and ...

Fever
Fever or pyrexia in humans is a symptom of an anti-infection defense mechanism that appears with Human body temperature, body temperature exceeding the normal range caused by an increase in the body's temperature Human body temperature#Fever, set point in the hypothalamus. There is no single agreed-upon upper limit for normal temperature: sources use values ranging between in humans. The increase in set point triggers increased muscle tone, muscle contractions and causes a feeling of cold or chills. This results in greater heat production and efforts to conserve heat. When the set point temperature returns to normal, a person feels hot, becomes Flushing (physiology), flushed, and may begin to Perspiration, sweat. Rarely a fever may trigger a febrile seizure, with this being more common in young children. Fevers do not typically go higher than . A fever can be caused by many medical conditions ranging from non-serious to life-threatening. This includes viral infection, viral, b ...

Vacuum Cleaner
A vacuum cleaner, also known simply as a vacuum, is a device that uses suction, and often agitation, in order to remove dirt and other debris from carpets, hard floors, and other surfaces. The dirt is collected into a dust bag or a plastic bin. Vacuum cleaners, which are used in homes as well as in commercial settings, exist in a variety of sizes and types, including stick vacuums, handheld vacuums, upright vacuums, and canister vacuums. Specialized shop vacuums can be used to clean both solid debris and liquids. Name Although ''vacuum cleaner'' and the short form ''vacuum'' are neutral names, in some countries (UK, Ireland) '' hoover'' is used instead as a genericized trademark, and as a verb. The name comes from the Hoover Company, one of the first and most influential companies in the development of the device. In New Zealand, particularly the Southland, New Zealand, Southland region, it is sometimes called a ''lux'', likewise a genericized trademark and used as a verb. The ...

Symptomatic Treatment
Symptomatic treatment, supportive care, supportive therapy, or palliative treatment is any medical therapy of a disease that only affects its symptoms, not the underlying cause. It is usually aimed at reducing the signs and symptoms for the comfort and well-being of the patient, but it also may be useful in reducing organic consequences and sequelae of these signs and symptoms of the disease. In many diseases, even in those whose etiologies are known (e.g., most viral diseases, such as influenza and Rift Valley fever), symptomatic treatment is the only treatment available so far. For more detail, see supportive therapy. For conditions like cancer, arthritis, neuropathy, tendinopathy, and injury, it can be useful to distinguish treatments that are supportive/palliative and cannot alter the natural history of the disease ( disease modifying treatments). Examples Examples of symptomatic treatments: * Analgesics, to reduce pain * Anti-inflammatory agents, for inflammation ca ...
