怎么分辨臭虫叮咬

很多人都听过一首流行歌曲：“晚安，睡个好觉，别让臭虫咬”，但却没几个人能认得出臭虫的叮咬痕迹。事实上，如果不确定是否真有臭虫，就没法确定臭虫叮咬。为了尽可能地辨别臭虫叮咬，要看看皮肤是否有典型的昆虫叮咬痕迹或者红色伤痕。要想准确判断是不是臭虫的咬痕，你必须确定睡觉的地方是否真的有臭虫。^[1]

步骤

检查咬痕

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/0\/09\/Identify-Bed-Bug-Bites-Step-1.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-1.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/0\/09\/Identify-Bed-Bug-Bites-Step-1.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 检查咬痕。寻找身上稍微变色、针状凸起的红点，直径约0.2厘米至0.5厘米。你也可能会发现比四周肤色红得多的麻疹或丘疹。在极少数严重的情况下，你甚至可能发现臭虫叮咬过后形成的直径大于0.5厘米的水泡。^[2]
   • 1厘米等于0.4英寸。
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/2\/28\/Identify-Bed-Bug-Bites-Step-2.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/2\/28\/Identify-Bed-Bug-Bites-Step-2.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 一觉醒来后，看看身上有没新的咬痕。要是醒来后发现身上有新咬痕或发痒的伤口，那床上就可能有臭虫。看看像不像是蚊子或跳蚤叮咬的——臭虫叮咬通常是红色的，并且和其他昆虫叮咬一样，会让人感觉轻微的肿胀、瘙痒和刺痛。找一找身上是否有一串或者随机分布的一片咬痕。之所以会这样，是因为臭虫一晚上会叮好几次。^[3]
   • 如果新的咬痕是白天才有的，那可能就不是臭虫咬的。
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/3\/30\/Identify-Bed-Bug-Bites-Step-3.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-3.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/3\/30\/Identify-Bed-Bug-Bites-Step-3.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 注意身上哪个部位被咬了。看看睡觉时露在外面的皮肤上是否有咬痕。还要检查一下宽松衣服下的咬痕。但要知道，臭虫不会咬脚底，所以脚底的咬痕不会是臭虫咬的。^[4]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/6\/6b\/Identify-Bed-Bug-Bites-Step-4.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-4.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/6\/6b\/Identify-Bed-Bug-Bites-Step-4.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-4.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 看看是否有过敏症状。如果你对臭虫过敏，可能就会发现皮肤上有类似湿疹或真菌感染的麻疹或皮疹。还要留意咬痕是否会变大、疼痛肿胀，甚至是有脓液渗出来。这些都是对臭虫叮咬过敏的常见症状。^[5]
   • 请注意，身体有可能会在两周后才对臭虫叮咬出现过敏反应。
   • 如果反应比较严重，那就得去看医生。

检查床铺

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/f\/ff\/Identify-Bed-Bug-Bites-Step-5.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/f\/ff\/Identify-Bed-Bug-Bites-Step-5.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-5.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 在床上寻找活的臭虫。仔细检查床上是否有长约0.1到0.7厘米的小虫子，它们通常呈红褐色，没有翅膀而且身子比较扁平。查看床垫和床单的折痕中是否藏有虫子。还要寻找臭虫可能褪下的壳。看看是否有长约0.1厘米的小白蛋和蛋壳，或者是差不多大小的白色幼虫。^[6]
   • 0.4厘米等于1/10英寸。
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/84\/Identify-Bed-Bug-Bites-Step-6.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-6.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/84\/Identify-Bed-Bug-Bites-Step-6.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 检查床单。寻找床单上的红色或锈色的污渍。这些可能是被压扁的虫子或者它们的粪便留下的。擦拭一下在床上用品上发现的任何黑色或红色的斑点。如果它们能被抹开，很可能就是臭虫的排泄物。^[7]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/3\/3d\/Identify-Bed-Bug-Bites-Step-7.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-7.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/3\/3d\/Identify-Bed-Bug-Bites-Step-7.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-7.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 检查床架。找一找床架内侧以及和墙壁之间的缝隙中是否有臭虫。床头板周围也要检查。在床单、床垫和弹簧床垫的管道、接缝和标签等位置搜寻。枕套和床上所有枕头的里面也不能漏过。^[8]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/4\/4d\/Stop-Bed-Bug-Bites-Immediately-Step-19.jpg\/v4-460px-Stop-Bed-Bug-Bites-Immediately-Step-19.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/4\/4d\/Stop-Bed-Bug-Bites-Immediately-Step-19.jpg\/v4-728px-Stop-Bed-Bug-Bites-Immediately-Step-19.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 根据床的状况来判断。在个别情况下，即使从来没有发现过臭虫，也不代表它就一定不存在。回想一下床垫已经用了多久，看看床单是否干净。如果是在酒店客房里，那就看看床垫是否包有一层塑料膜。要是没有，被臭虫侵扰的可能性会更大。

寻找臭虫的其他迹象

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/d\/d6\/Identify-Bed-Bug-Bites-Step-8.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-8.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/d\/d6\/Identify-Bed-Bug-Bites-Step-8.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-8.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 看看其他家具里是否藏有臭虫。检查椅垫的下面、椅子和沙发的缝隙。抽屉的连接处也不能放过。
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/f\/f7\/Identify-Bed-Bug-Bites-Step-9.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-9.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/f\/f7\/Identify-Bed-Bug-Bites-Step-9.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-9.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 检查其他地方。看看剥落的墙纸内侧以及墙饰下方是否藏有臭虫。电源插座的插孔里面，墙壁和天花板、地板的接头处以及窗帘的褶皱都有可能是臭虫的藏身之处。
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/8d\/Identify-Bed-Bug-Bites-Step-10.jpg\/v4-460px-Identify-Bed-Bug-Bites-Step-10.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/8d\/Identify-Bed-Bug-Bites-Step-10.jpg\/v4-728px-Identify-Bed-Bug-Bites-Step-10.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 闻一闻你怀疑有臭虫的地方。寻找是否有微甜、发霉的气味。有臭虫的地方可能会发出芫荽或者类似椿象的气味。如果你怀疑某个地方有臭虫，而且可以闻到潮湿的老房子味道或者任何其他气味，那就很可能会藏有臭虫。^[9]
