The answer to 'how to kill extermination' is that there is no such thing as 'killing extermination'. Extermination refers to the complete elimination of a pest infestation, not a physical action. To effectively get rid of pests like rodents, insects, or other unwanted animals, you'll need to take a comprehensive approach that addresses the root causes and uses a combination of prevention, removal, and control methods.
This typically involves sealing entry points, removing food sources, using humane traps or baits, and applying pesticides or other treatments as needed. However, it's important to follow all safety precautions and consider calling in a professional pest control technician, especially for severe infestations or when dealing with dangerous pests.
