Step-by-step explanation:
Toxic tracking powder is primarily used as a poison for rodents. It is commonly employed to control and eliminate rodent populations that pose a threat to human health and property. The powder typically contains toxic substances that are attractive to rodents and once ingested, they act as a poison, causing death.
In addition to poison rodents, toxic tracking powder is sometimes used for monitoring pest populations. By placing the powder strategically, it can help identify the presence of rodents and determine their movement patterns. However, the primary purpose of toxic tracking powder is to poison rodents and control their populations.
