Today we'll be discussing bed bugs by first describing them; second taking a look at their come back and finally we'll talk about the eradication of the bed bugs. . . In 1939, a Swiss pharmacist named Paul Herman Muller discovered that a chemical known as DDT could effectively solve the world's pest problems. Countries stricken with Malaria and Typhus considered it a miracle, nearly eliminating Typhus altogether. The bed bug population was almost wiped to extinction with the frequent DDT sprays in the United States , but in 1962 Rachel Carson wrote a book called Silent Spring that explained how DDT harmed the bird population and could cause cancer. Consequently, DDT was banned and the bed bug population began to grow.
