Pest control refers to use the use of methods and chemicals aimed at eliminating pest infestation. Use of pesticides and fungicides to control is the practice that is slowly fading away. Instead, some homeowners have welcomed biological or organic pest control methods when it comes to eliminating or controlling pest infestation.
Ideally, biological pest control methods are a natural way of dealing 
with pest infestation. In most instances, organic methods do not completely eradicate the pest. However, this natural pest control method provides homeowners with many benefits absent in other pest control methods.
Environmentally friendly
One of the main strengths of biological pest control is that they are environmentally friendly. There are no chemical runoffs, which can affect other organisms in the area. As such, natural pest control methods are risk-free. You do not have to be troubled by the risk of handling insects in your backyard like beetles, ladybugs, lacewings, and Beneficial nematodes. Biological control methods are also recommended for organic farming.
Specific
Each biological pest control method is specific. As such, using a particular method does not pose any health hazard to other species living in the ecosystem. This is unlike pesticides that kill everything in the paths, even some beneficial microorganisms. For instance, use of a pesticide like DDT also poses a significant risk to birds.
Cost effective
Biological pest control methods are cost effective. Compared to chemical pest control method, biological control methods are cheaper that use of pesticides. The fast acting nature of pesticides, which poses a significant risk to the health and environment, is actually what makes them seem so attractive. However, a closer look at these two options from a cost perspective will certainly favor biological pest control methods.
Sustainable
Biological pest control methods are sustainable. Successfully established species can naturally maintain their populations without your interference. This is unlike chemical control methods that are progressively applied depending on the nature of infestation. This aspect makes organic methods cost efficient and environmentally friendly.
If you are one of those people that are yet to use biological control methods in pest control, you have every reason to do so. Using this method is good for your health, environment and is cost-effective. The ills associated with most chemicals are real. As such, any rational being should certainly try biological pest control methods.
