Pest control involves managing species that are defined as pests, such as insects, rodents, or other animals that can cause harm to human health, the environment, or property. The process starts with proper identification of the pest, and continues with determining the extent of the infestation, and choosing the best method for control. Chemical treatments are one option, but there are also many other safe, effective, and environmentally friendly methods, such as physical exclusion techniques, using natural predators, and integrated pest management.
