Home Tips

Biological pest control can be one of the methods that a lot of homeowners like to work with. It is often seen as more natural compared to some of the other options and allows you to safely get rid of the pests around your home, as long as you do it in the proper manner. There are actually a few different methods of biological pest control that you can choose depending on the type of pest that is in your area and how you think you can effectively get rid of the pest as well. Let’s dive into some of the different methods of biological pest control to see which one is right for you.

Predation is one of the most common methods used when it comes to biological pest control. You are able to take the predators of your pest and then augment, conserve, or import them to help lower the number of the pests that are in the area, at least down to a level that is more manageable. Keep in mind with this method that you will not completely eradicate the pest population.

Many homeowners are going to choose predation because it can help you to control the pests in your yard without having to use harmful chemicals. But you need to be careful and make sure that you introduce the right species of predator to the area, or it can be bad for the environment.


When you introduce a parasitoid species, it can be used to help lower the size of the population of your pest species. The difference between a parasitoid and a parasite is that the parasite is going to actually live on the surface or within the organism. On the other hand, the parasitoid is going to produce larvae that can act more as a parasite as well. This can be a unique option and you will need to study up to make sure that you choose the right type of parasitoid to help with your pest problem.


Competition can be a successful way to handle some of the pests that try to get into your home. This one is all about introducing a competitor species into the environment around you. this is going to result in interspecific competition, which will reduce how fit the pest species is and can make it harder for them to grow and thrive in that area. There are a few different types of competition that you can try out for your pest problem including:

  • Interspecific competition: This is going to refer to the competition that happens between two different types of species.
  • Intraspecific competition: This is the competition that happens within the same species.
  • Fitness: This is going to come from an evolutionary sense and will refer to the survival and reproductive success of an organism.

You will need to pay attention to which method will work the best for the pest species in your home to make sure that you introduce the right competition to the area.

Introducing Pathogens

Another method that you can choose to use is to introduce pathogens into the area. This is when you add in agents that can cause a disease in the pests that are bothering you. They can be living like bacteria, or nonliving, like with viruses. Pathogens can be effective because they will help to decrease the size of the population and often they will not cause any harmful effects on other organisms in the area.

There are a few options that come with the type of pathogen that you will choose. You can have a density-dependent limiting factor, which is going to be factors that will limit the growth of the population based on the current size of the population. Or you can go with the density-independent limiting factors, which are going to be the ones that will occur independent of the population status of the species. You should talk with a professional to see which one is right for your needs.

Benefits of Using Biological Pest Control

There are a number of benefits to choosing this type of pest control over some of the others. But the important thing here is to make sure that it is implemented in a safe and effective manner. When you can do it this way, you will find that biological pest control can be safe and even sustainable to the environment. It is also a lot more cost effective compared to some of the other pest control methods that you may choose.

The homeowner who chooses to work with this one will need to do extensive amounts of pre-planning and research to make sure that the biological agent is only going to go after the organism that is bothering you. These agents are also self-sustaining and free-living, which means that they require minimal amounts of management from you.

Biological pest control can also be a good thing because they have little or no impact on the health of the humans around them. When you compare this to pesticides and other chemicals that you may use to help get rid of the pests around you, this can be welcome news. You will also enjoy that pest organisms will not develop a resistance to parasitoids, competitors, or predators. They can build up this resistance to some of the chemicals that you try to use in order to get rid of them. This makes biological pest control a much better option to use if you are looking for a long-term solution to your pest problem.
