Bed bugs live on blood. They usually eatevery few days or week, but they don’t need to eat that often to survive. Thetiny bugs can go months without a meal. After such an unwanted fast, or evenany time they haven’t recently fed, their bodies will be flat. And that helpsthem hide in little cracks near a bed. But once a bed bug has gorged on a meal— usually human blood, and usually while you are asleep — it plumps up like aminiature balloon. Then it returns to hiding in wait of its next meal.
床虱以血液为生，几天或者一周吃一顿，并不是很频繁。更小的昆虫甚至几个月才吃一次。再这样无关紧要的慢速下，或者任何时候没有饱餐一顿，他们的身体开始变瘪。这样的体型有利于他们藏匿于床上更小的缝隙中。但是如果他们一旦吸食人类血液吃饱后（通常在人类熟睡的情况下），他们的身体则又开始像气球一样鼓起来。然后返回藏匿地点等待下次美餐。
In the past 15 years or so, the bed bug, hasbecome common all over the United States, Australia, Europe and parts of Asia.Its comeback has surprised many people because until recently, the pest hadbeen rare for some 60 years in these parts of the world. During that time, somepeople didn’t even know the bed bug existed. They thought it was a made-up creaturefrom the nursery rhyme。
在过去15年间，床虱在美国、澳大利亚、欧洲及部分亚洲地区都比较常见。它的回归让许多人都觉得很震惊，因为从过去的60年到现在这种虫子在世界上的上述地区都很罕见。那时，有些人甚至都不知道床虱的存在，以为它们只是童谣里的虚构生物。
