Which of the following is NOT a method of non-chemical animal control?

Non-chemical animal control methods focus on preventing or managing pest populations without the use of toxic substances. The correct choice identifies poisoning as a method that involves chemicals and therefore does not fit into the category of non-chemical control.

Exclusion is a non-chemical method where physical barriers are used to prevent animals from entering an area. This could involve sealing holes or using screens to block entry points. Sanitation also falls under non-chemical control as it involves the removal of food sources and potential nesting sites, thereby reducing the attractiveness of an environment for pests.

Shooting, while it may involve some level of direct intervention, is not classified as a chemical method as it uses physical means to control animal populations. Thus, poisoning clearly stands out as the only method among those listed that relies on chemical agents for pest control.
