Pests live where they are not wanted or cause harm to crops, people or animals. Pesticides can help get rid of them. Though you may think of pesticides as insect killers, they include chemicals to control weeds, rodents, mildew, germs and more. Many household products contain pesticides.
Pesticides can protect your health by killing germs, animals or plants that could hurt you. However, most pesticides can be harmful to people or pets. You might want to try non-chemical methods first. If you do need a pesticide, use it correctly. Be especially careful around children and pets. Disposing of pesticides properly is also important - it can help protect the environment.
Biologically-based pesticides are becoming more popular. They often are safer than traditional pesticides.
