Pesticides are special chemicals used to kill harmful pests such as bacteria and moulds. They can be found in many forms such as insecticides, herbicides, lures and baits.
Types of Pesticides
Bactericides work by preventing the spread of bacteria. One example is chlorine which is used in swimming pools. These can be effective in controlling localized populations of bacteria, however, there are more effective pesticides used to control fungi and insects.
Baits are a ready mixed substance which is combined with food. These are effective in eradicating household pests such as cockroaches.
Fungicides control or destroy fungi growth in plants such as grape vines and fruit trees.
Herbicides control weed growth and other unwanted plant growth by using chemicals such as glyphosate to control the weed accumulation in gardens and farmlands.
Insecticides are used to suppress or destroy pests known as insects. They are used to control insect species ranging from moths to fruit flies.
Lures are basically chemicals which attract pests. These can be in the form of cheese in a mousetrap and are strictly food-based.
