以人类血液为食！已蔓延至亚洲……

South Korea has become the latest country to declare war on bedbugs following a wave of outbreaks, with bathhouses, university dorms, and train stations across the country on high alert.

Bedbugs are small, flat, parasitic insects that feed solely on the blood of people and animals while they sleep. Bedbugs are reddish-brown in color, wingless, range from 1mm to 7mm, and can live several months without a blood meal.

半翅目昆虫具有医学上的重要特性——咬人。臭虫喜欢吸食人体和畜体的血液，人体被臭虫叮咬后，会出现皮肤红肿发炎、瘙痒疼痛的症状，有时还会传播其他疾病。如果床铺里有臭虫，很容易影响睡眠质量，给生活带来巨大困扰。

尽管从臭虫身上分离出包括乙肝病毒、抗生素抵抗的细菌在内的多种病原体，但目前还没有证据显示臭虫是一些病毒和细菌的载体，因此臭虫叮咬人传播疾病的概率相比其他昆虫小得多。

对人类的危害主要表现在严重的过敏症和精神上的损害，有的人被臭虫叮咬会导致噩梦、失眠、焦虑、抑郁症，甚至选择自杀。

Bedbugs are not known to spread disease. Bedbugs can be an annoyance because their presence may cause itching and loss of sleep. Sometimes the itching can lead to excessive scratching that can sometimes increase the chance of a secondary skin infection.

臭虫主要栖息于人们睡觉的地方，尤其是室内墙壁、木制家具的缝隙、草垫、床席、床头柜等处，或交通工具及公共场所的桌椅缝隙中。臭虫有群集现象，白天隐匿，夜晚活动吸血，并且对宿主没有严格条件选择，除了人以外，也会吸食其他哺乳类动物的血，甚至鸟类也不放过。

Bedbug infestations usually occur around or near the areas where people sleep. These areas include apartments, shelters, rooming houses, hotels, cruise ships, buses, trains, and dorm rooms.

They hide during the day in places such as seams of mattresses, box springs, bed frames, headboards, dresser tables, inside cracks or crevices, behind wallpaper, or any other clutter or objects around a bed.

Bedbug infestations are commonly treated by insecticide spraying. If you suspect that you have an infestation, contact your landlord or professional pest control company that is experienced with treating bedbugs. The best way to prevent bedbugs is regular inspection for the signs of an infestation.
