Which of the following is a benefit of using borates in pest control?

Using borates in pest control is advantageous primarily because they are low in hazard to the environment. This means that when they are applied as directed, they have a minimal impact on non-target organisms, including beneficial insects, wildlife, and aquatic systems. Borates are naturally occurring minerals that effectively control wood-destroying pests such as termites and wood-boring beetles while being safer alternatives to more toxic chemical pesticides.

Furthermore, they have a relatively low toxicity to humans and pets when used correctly, supporting the favorable environmental profile of borates. This characteristic makes them a popular choice for pest management, particularly in settings where minimizing ecological disruption is a priority.

The other options listed do not represent accurate benefits of using borates in pest control. High toxicity to humans would not be a benefit, nor does borate effectively repel all insects. Additionally, borate applications do not require frequent treatments, as they persist in treated materials for extended periods, further emphasizing their low environmental impact.
