This essay briefly introduces why acaricides are in great need and the classification of them. A screening for acaricidal activity of extracts with some known medicinal organisms attributes could lead to the discovery of new agents for pest control. So we put forward 3 kinds of biological acaricides, namely: botanical acaricides, microbiological acaricides and animal-based acaricides and compare their advantages and disadvantages with each other. We discuss their applications and research progress, and introduced present situation and future trends of biological acaricides finally.
