The use of chemical pesticides to control pest problems has been the most prevalent form of consciously-applied pest management in the decades following WWII. The first generation included highly toxic and pretty much ineffective compounds, such as arsenic and hydrogen cyanide. The following generations included largely synthetic organic compounds, such as the infamous DDT, which at the time were deemed miraculous for their broad spectrum, high toxicity, and the fact that they weren’t water soluble, so rain couldn’t wash them off.
At the moment, Canadians use millions of pounds of pesticides
every year to combat invaders in agricultural crops, gardens, business properties, schools, hospitals, public transportation, and parks. What’s fundamentally wrong about pesticide use is that it doesn’t solve pest problems – it only eliminates existing infestations, leaving the conditions that led to a pest infestation in the first place unchanged. In other words, they address the symptoms, and not the cause, of the problem.
