What characteristic do fumigants for rodents possess?

Fumigants used for rodent control are characterized by their ability to quickly affect the target species. They generally provide fast-acting results, which, while not always achieving 100% control, can effectively reduce rodent populations in a short period. High toxicity is a critical characteristic of these products, as they must be potent enough to eliminate rodents while being used in a manner that minimizes risk to humans and non-target animals when applied correctly.

Additionally, many fumigants can have a broader spectrum of activity, which means they may also control insect pests along with rodents, such as house mice. This multifaceted effectiveness enhances the utility of fumigants in pest control strategies since they can address multiple pest problems simultaneously. Understanding these characteristics is vital for practitioners, as it influences both the choice of pest control method and the safety measures that must be taken during application.

Thus, the answer encompasses all these attributes, making it comprehensive and accurate.
