Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
Biocides can be added to other materials (typically liquids) to protect them against biological infestation and growth. For example, certain types of quaternary ammonium compounds are added to pool water or industrial water systems to act as an algicide, protecting the water from infestation and growth of algae. It is often impractical to store ...
Infestations can be classified as either external or internal with regards to the parasites' location in relation to the host. External or ectoparasitic infestation is a condition in which organisms live primarily on the surface of the host (though porocephaliasis can penetrate viscerally) and includes those involving mites, ticks, head lice and bed bugs.
Chinese agronomy recognised biological control by natural enemies of pests and the varying of planting time to reduce pests before the first century AD. The agricultural revolution in Europe saw the introduction of effective plant-based insecticides such as pyrethrum , derris , quassia , and tobacco extract.
Biological pest control is a method of controlling pests such as insects and mites by using other organisms. [12] It relies on predation , parasitism , herbivory , parasitody or other natural mechanisms, but typically also involves an active human management role.
A fish parasite, the isopod Cymothoa exigua, replacing the tongue of a Lithognathus. Parasitism is a close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life.

Bed bug infestations spread easily in connecting units and have negative effects on psychological well-being and housing markets. In response, many areas have specific laws about responsibilities upon discovering a bed bug infestation, particularly in hotels and multi-family housing units, because an unprofessional level of response can have the effect of prolonging the invisible part of the ...
A periodic check of susceptible foodstuffs is necessary, especially in summer months when most insects are more active. In the event an infestation is discovered, steps must be taken to eradicate the insects. Controlling an infestation is a lengthy process and insects may still be seen, albeit in dwindling numbers, for several weeks.
