"Pests, they come in all shapes and sizes and disrupt our lives in a variety of ways. At first, they’re merely annoying, and we do our best to ignore them. But if we don’t take them seriously, they can become quite dangerous. For some, death seems to be the easiest solution. But the problem with the pests is that what they leave behind is just as dangerous. " 
害虫大小不一、外形各异，而且时不时地扰乱我们生活。因为只是恼火，我们最初也就无视他们的存在。但他们也可能因为我们一时的疏忽大意而肆虐得一发不可收拾。对于他们中的一部分，消灭看似最为简便的解决方法，而我们完全没意识到这些害虫留下的潜在危险。
