Using biological controls: predators. To get the best results it is important to know how biological controls behave. Many of the predators used for biological control are more accurately termed parasitoids as they kill the host whereas a true parasite does not; these animals lay eggs in a host, the grub grows and feeds inside its prey, only killing the host when it completes its development.
