The idea that plants can benefit from the application of their herbivore's enemies is the principle behind biological control. Consequently, much of EPN biological research is driven by agricultural applications. Examples of the top-down effects of entomopathogenic nematodes are not restricted to agricultural systems.

They have been used in companion planting as pest control in agricultural and garden situations, and in households. Certain plants have shown effectiveness as topical repellents for haematophagous insects, such as the use of lemon eucalyptus in PMD, but incomplete research and misunderstood applications can produce variable results.
