 1 Preview Questions
• Pests are animals that cause problems 
 for people – for example, rats. What are 
 some other examples of pests?
• Have you ever had a problem with a 
 pest? Describe it.
 3 From the 1950s until recently, people hadn’t had a 
big problem with bedbugs. But that has changed. 
Why have the bugs returned? The CDC (Centers for 
Disease Control) has been studying the problem for
the past few years and lists the following reasons: 1) 
People travel more today, increasing the chance that 
bedbugs will come home with them; 2) Most people 
have never had bedbugs, so they don’t recognize the 
problem early; 3) Pesticides that had worked in the 
past don’t work today; 4) Officials haven’t found a 
successful pesticide yet.
