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.
For example, peer-reviewed publications have consistently shown that ultrasonic devices do not drive unwanted animals away. [ citation needed ] Second, even when the repellent has been shown to work, animals in dire need of food will "hold their nose" and eat anyway because the alternative is essentially death by starvation.
A Hygieostatic Bat Roost, custom-built to house bats for biocontrol of mosquitos. Biological pest control, or "biocontrol", is the use of the natural enemies of pests like mosquitoes to manage the pest's populations. There are several types of biocontrol, including the direct introduction of parasites, pathogens, and predators to target mosquitoes.

Pest control is the regulation or management of a species defined as a pest; such as any animal, plant or fungus that impacts adversely on human activities or environment. [1] The human response depends on the importance of the damage done and will range from tolerance, through deterrence and management, to attempts to completely eradicate the ...
A biopesticide is a biological substance or organism that damages, kills, or repels organisms seens as pests.Biological pest management intervention involves predatory, parasitic, or chemical relationships.
For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and genetics . Some focus on the micro-scale (e.g. molecular biology , biochemistry ) other on larger scales (e.g. cytology , immunology , ethology , pharmacy, ecology).
For example, weeds reproducing from last year's seed can be prevented with mulches and pre-emergent herbicide. [citation needed] Pest-tolerant crops such as soybeans may not warrant interventions unless the pests are numerous or rapidly increasing. Intervention is warranted if the expected cost of damage by the pest is more than the cost of ...
