Which pesticide is specifically used to control mites?

The correct choice is B because a miticide is a type of pesticide specifically designed to target and control mites. Mites, which are not true insects but belong to the arachnid class, require specialized control measures that are often ineffective against other pest categories like insects.

Acaricides, while often used interchangeably with miticides, are more general and can refer to any substance that kills arachnids, including mites and ticks. Therefore, miticide is the more precise term indicating a pesticide that deals specifically with mite control.

Insecticides are formulated to target insects specifically and would not be effective against mites. Apyreticide is not a recognized category of pesticide and does not pertain to mite control at all. Understanding the specificity of these terms is crucial in pest management, ensuring that the correct type of pesticide is applied for effective results.
