Nano-Sized, Venomous Insects

Nano-sized, Venomous Insects (ナノサイズの毒蟲, Nanosaizu no Dokumushi; Viz "Nano-sized Venom Beetles") are a special breed of insects used by select members of the Aburame clan as part of their Parasitic Destruction Insect Technique. These bugs destroy their enemies' cells, causing excruciating pain in the process.

Unlike the standard kikaichū, which are able to act independently of the user, the nano-sized insects can seemingly only be transferred onto a victim's body by direct physical contact; though only a mere touch from the user's skin is required as the bugs can circumvent most forms of clothing.[2] However, this apparently does not apply to the user's own clothes, who must instead remove items in order to effectively increase their chances of hitting the target.
