The answer to 'which is worse extermination or' is that extermination is generally worse than other pest control methods. Extermination typically involves the use of powerful chemical pesticides that can be harmful to both humans and the environment. These chemicals can linger in the home and pose long-term health risks, especially for children and pets.
In contrast, integrated pest management (IPM) approaches focus on using a combination of non-chemical methods like sealing entry points, removing food sources, and using targeted, low-toxicity pesticides as a last resort. IPM is generally considered a safer and more sustainable alternative to extermination.
