Pesticides
Pests live where they are not wanted or cause harm to crops, people, or animals. Pesticides can help get rid of them. Pesticides are not just insect killers. They also include chemicals to control weeds, rodents, mildew, germs, and more. Many household products contain pesticides.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
