The answer to 'which is worse extermination or' is that extermination is generally considered worse than other pest control methods. Extermination typically involves the use of toxic chemicals or other lethal means to eliminate pests, which can be harmful to both the environment and the health of humans and pets. In contrast, other pest control methods like trapping, exclusion, and integrated pest management (IPM) tend to be less harmful and more focused on prevention and management rather than outright elimination.
While extermination may be necessary in some cases, such as for severe infestations or when dealing with particularly dangerous pests, it should be considered a last resort. Other pest control methods are often more effective in the long run and can help prevent future infestations without the same level of environmental and health risks.
