Pesticides are chemical substances that prevent, repel, impair or kill a pest. A pest is defined as any organism, higher or lower level, that competes with humans for food, causes illness among humans, is destructive to property or is simply a nuisance. There have been pesticides in use since 500 BC and current pesticides are generally synthetic, although natural pesticides are also in use. Pesticides can act against bacteria, fungi, weeds or other plants, viruses, insects or higher animals like mollusks, rodents, birds, worms or spiders.
