A pesticide is a substance used to kill feral animals, insects, fungi or plants. There are thousands of different pesticides in use today. Pesticides are used in houses, shops, offices, sheds, gardens, farms, gas stations and other places. Most of the pesticides used today are chemicals which have been developed in a laboratory by scientists and produced in factories. Some pesticides are very hazardous, they can be harmful to humans and other living things. They can contaminate land, the air, food crops, water ways and seriously harm or kill native animals, pets and domestic animals. To the user, pesticides can also cause great harm and sometimes death to a person or other living things nearby.
Pesticides come in three different forms:
solids, which come in powder form (like flour), or in crystal or granular form (like sugar)
liquids, which look like milky water
aerosols, which are sprayed out in a fine mist
