Which type of pesticide is specifically used to control mites and ticks?

Acaricides are specifically designed to control mites and ticks, which are arachnids belonging to the class Arachnida. This group includes pests that can harm plants and animals, including humans. Acaricides work by targeting the physiological processes of these pests, often disrupting their nervous systems or interfering with their development and reproduction.

The other types of pesticides listed serve different purposes: algicides target algae; insecticides are aimed at insects and are not effective against arachnids; and herbicides are used to control unwanted plants or weeds. Each type of pesticide is formulated for specific organisms, highlighting the importance of using the correct one for effective pest management.
