The Parasitic Destruction Insect Technique is a practice exclusive to the Aburame clan.
When children are born into the clan, their bodies are offered to insects to be used as a nest. Over the years, as the child grows up, they are instructed in the secret techniques of the clan, and learn how the insects may serve them in combat.
Most Aburame are inhabited by kikaichū, however, the clan does not limit themselves to the use of one type of insect. Torune and Shikuro for example, have rinkaichū — a rare type of insect even within the Aburame clan — inhabiting their bodies. Shino was also shown to host another unique insects in his body called the kidaichū — an insect he noted was problematic to host because of its characteristics. Muta used shōkaichū, which act as trackers of sorts. Yōji used kochū, which can infect enemies with a deadly paralysing poison.
