Which statement regarding pesticides used in structural pest control is true?

The statement that even the least hazardous pesticide can cause human harm is accurate because all pesticides, regardless of their level of hazard, carry some degree of risk. This includes potential health effects due to exposure, which can range from mild irritations to more severe health issues depending on various factors such as the route of exposure, duration, and individual sensitivity. It's important to recognize that even those pesticides deemed "least hazardous" must be handled with care and according to guidelines to minimize any potential risks to human health.

Awareness and understanding of the risks associated with all types of pesticides are essential for safe handling and application. Public health guidelines emphasize the importance of using pesticides responsibly and following label instructions to mitigate exposure risks. This perspective is crucial when discussing safety in pest control practices.
