What technique cannot be adopted by structural pest control operators when controlling birds?

Shooting is a technique that generally cannot be adopted by structural pest control operators when controlling birds due to legal and regulatory restrictions. Many regions have strict laws governing the treatment and control of wildlife, including birds, and in many cases, lethal methods such as shooting may require special permits or may be prohibited altogether, particularly within urban or residential areas.

In contrast, trapping, exclusion, and cleaning are commonly acceptable methods for managing bird populations. Trapping allows for the humane capture of birds, exclusion involves preventing access to buildings through barriers, and cleaning is essential for removing nesting materials and droppings that can pose health risks. These methods are focused on non-lethal, long-term solutions that align with the ethical considerations and regulations associated with wildlife management.
