Which of the following is a control method for ground squirrels?

When managing ground squirrel populations, employing a combination of strategies can be effective, and all listed methods play a crucial role in integrated pest management.

Fumigation is a method that involves the introduction of gas into burrow systems, targeting ground squirrels residing underground. This method can be particularly useful in reducing populations quickly, especially in areas where other methods may be less effective.

Trapping is another key control method that allows for the removal of ground squirrels from an area without the use of chemicals. It can be particularly useful in settings where non-target species may be a concern, or where environmental safety is a priority. Utilizing traps can also provide a means of monitoring the population.

Poison bait is used as a strategy to control ground squirrel populations by delivering a lethal dose of poison to the animals. It is essential to ensure that the bait is applied correctly to minimize risks to non-target species and to comply with local regulations regarding pesticide use.

Using a combination of fumigation, trapping, and poison bait can provide a comprehensive approach to managing ground squirrels, addressing the issue from multiple angles for more effective population control. Hence, recognizing that all these methods can be valid control options is vital in pest management practices.
