The answer to 'what causes extermination' is that extermination refers to the process of eliminating or getting rid of pests, such as insects, rodents, or other unwanted organisms, from a specific location. Extermination is typically carried out by professional pest control technicians who use specialized methods and products to effectively and safely remove the pest infestation.
Pests can be caused by a variety of factors, including poor sanitation, improper food storage, and the presence of entry points or harborage areas in the home. Extermination is often necessary to address severe infestations or when DIY methods have been unsuccessful in controlling the problem.
