The advantages of biological pest control

Updated February 21, 2017

Biological control is a safe and natural approach to keeping pests such as aphids and mites at bay. It is an economical and effective technique in pest control and management in agriculture programs. The method uses natural pest enemies to eliminate harmful insects in order to reduce the risk of pesticide abuse and possible environmental chemical pollution.


Classical biological control is inexpensive and produces long-lasting effects. Aside from initial expenses for importation, collection and rearing, costs are kept to a minimum. When a natural enemy is used and becomes successful, the procedure will rarely require additional biological input and it will continue killing the pests without any direct assistance from you, and at no additional cost. Biological control is proven to be highly successful and economical. Even when the procedure has been less than successful, it is still able to produce a remarkable benefit-to-cost ratio.


Another advantage of biological control is based on its capacity to provide a semipermanent regulation for devastating environmental and agricultural pests that may be a challenge or even impossible to control using the more traditional, chemical means.

Biological control is also recognised as being more effective against agricultural pests that are less harmful, that only need to be controlled and suppressed, and not permanently eliminated. Biological control is more environment-friendly and typically more lucrative than chemical pesticides.

Eco Friendly

Biological control agents are nonpolluting and therefore environmentally acceptable and safe. Typically, the species that are used are specific to the targeted weeds or pests. The biological control method avoids the use of ecologically and environmentally hazardous chemicals, so in that way it promotes natural balance.

Catalyst for Future Improvements

The application of biological control practices is just the beginning of more natural and greener approaches to pest control. With more studies and experiments, biological control could transform pest control in the future, greatly reducing the need for pesticides and herbicides. Furthermore, since it possesses a potentially huge economic value, employment and job opportunities could dramatically increase in the agricultural field. Permanently eliminating dependency on chemicals means increased biodiversity as well.
