Which fumigants are commonly used for controlling rodent pests?

The correct choice is commonly acknowledged as aluminum phosphide and sulfuryl fluoride because both of these fumigants are effective for managing rodent pest populations.

Aluminum phosphide releases phosphine gas when it comes into contact with moisture, which is lethal to rodents and is widely used in various settings, including agricultural and storage facilities. Its effectiveness against a range of pests, including rodents, makes it a popular choice among pest control professionals.

Sulfuryl fluoride, on the other hand, is also utilized for its efficacy in controlling various pests, including rodents. It penetrates structures effectively and is particularly advantageous in scenarios requiring thorough fumigation due to its low toxicity to humans at fumigation concentrations but high toxicity to rodents.

While the other options include fumigants that are used for different pest control applications, they are not predominantly recognized for rodent control. For example, methyl bromide and chloropicrin are more commonly associated with agricultural pest control strategies rather than specifically targeting rodents. Formaldehyde, although a potent biocide, is not typically classified as a fumigant for rodent control. Therefore, the combination of aluminum phosphide and sulfuryl fluoride is distinctly suited for effectively managing rodent populations.
