Which of the following terms refers to a product that targets mites?

The term that specifically refers to a product designed to target mites is "miticide." Miticides are substances formulated to kill or control mite populations, which are arachnids that can cause significant damage to plants, livestock, or health in certain environments. These products are tailored to disrupt the life cycles of mites, leading to their mortality and helping to manage infestations effectively.

In the given options, while "acaracide" is sometimes used synonymously with miticide, "miticide" is the more widely recognized and accepted term in pest management. The other options refer to products targeting different pests: nematicides are for nematodes, a type of roundworm, and insecticides are for insects. Therefore, "miticide" is the precise term for products aimed specifically at controlling mite populations.
