The user of this technique is capable of covering either limited parts or the entirity of their body with poisonous nano-sized insects. The user can subsequently infect the opponent with these bugs, causing an excruciatingly painful and almost certain fatal injury, unless the afflicted area is swiftly removed. These insects can only be transferred on to the victim's body by direct physical contact but only a mere touch from the user's skin is required, as the bugs can seemingly circumnavigate most clothing. However, this apparently does not apply to the user's own clothes, who most instead remove items in order to effectively increase the transferable surface area of the technique.
Although the technique derives from the Aburame Clan, it is a rare ability even among their members. Madara Uchiha claims Shikuro Aburame has the antidote for the bugs' poison, which Torune also appears to possess.
