A bed glitch infestation is a nightmare . On top of the forcible discomfort induce by bite , financial botheration is inflicted if you rebound for the only proven , yet very expensive , extermination method acting , which lie in of blasting the home with 50 ° C ( 122 ° F ) air .
Once the leechlike encroacher have been crisply fix , the ordeal was believed to be over and the phantom skin - crawling sensation could at long last lessen .
It turns out that ’s not quite the character .
bug-hunter and a public wellness expert from North Carolina have discover that the bug ( Cimex lectularius ) impart behind high levels of the allergic reaction - inducing moleculehistaminecollected in family dust .
According to their study , even after undergoing a heating treatment and passing three blissfully layer hemipteran - free months , previously infected animation blank can hold up to 180 times more histamine than house that have never hosted the insects .
The data was gathered from 14 infested apartment and 10 un - infested neighboring flat all in the same building complex , and liken to five control apartments located at least 8 km ( 5 miles ) aside .
“ The high concentrations , persistence , and proximity to humans during rest advise that bed bug - farm histamine may present an emerging contaminant and pose a serious health risk in the indoor environment , ” they write in the journalPLOS ONE .
Bed bugs were not know to raise allergens , though their saliva can cause an resistant reception come after a morsel , until a 2015 study find that the insects excrete histamine in their dejection to chemically intercommunicate with another . We humans also produce histamine , but use it for other intent . When our body detects the presence of a strange object or organism , white blood jail cell release histamine in orderliness to ramp up a defensive resistant answer . The resulting inflammatory process create classic allergy symptoms such as reeking eye and a fluid nose .
Exposure to airborne , international histamine is dangerous to the great unwashed with existing allergy or asthma because it ramps up their already overactive resistant system . Skin liaison with histamine can result in an antsy , scaly rash have sex asatopic dermatitisor eczema . And since seam microbe histamine lingers in dust – the swirling , easily spreadable bane to cleanliness – inhabitants of once - infested family and apartment will have a hard time avoiding some character of inter-group communication .
The source conclude that a new layer bug eradication proficiency incorporating a combination of insect zapping and histamine neutralization needs to be developed . Until that day , there is one other choice …
True to their name , seam bug prefer to bunch up on soft , upholstered surfaces so that they can crunch on their reclining hosts at nighttime . accordingly , this is where their histamine - loaded excrement is concentrate . Though we must hope that the resident of these apartments attempt to make clean their furniture after the plague was observed , whatever they did was apparently not potent enough to get rid of the histamine pollution that had infiltrated the fabric .
The logical resolution ? Burn the piece of furniture and make a fresh scratch .
