What is the name of a pesticide that is formulated specifically to control mites?

Acaricide is the correct answer because it refers to a specific class of pesticide designed to target and control mites and ticks. Mites, belonging to the arachnid family, require specialized compounds for effective control, which is where acaricides come into play. These substances work by disrupting the mite's physiological processes, thereby providing effective pest management.

In contrast, rodenticides are specifically formulated to control rodents and are not effective against mites. Herbicides are used to manage unwanted plants (weeds) and do not target animals such as mites. Insecticides target insects and may have some activity against certain pests that are insects but are not designed for arachnids like mites. Therefore, acaricides are uniquely suited for controlling mite populations, making them the appropriate choice in this context.
