What Biological Control Means
Instead of relying only on a conventional insect-control product, biological control introduces or supports organisms that naturally suppress a target pest. The exact method depends on the pest and the treatment program selected by the arborist.
When It May Be Appropriate
Biological control may be considered when a specific harmful pest has been identified and a compatible beneficial organism or management approach is available. It should not be marketed as a generic treatment for any insect seen on a plant.
