Sometimes a Torture Technician isn't content with the usual types of sharp, blunt or other torture implements. Sometimes they decide to employ living creatures to cause pain or terrify the hapless victim.
Insects and spiders are the most frequent creatures used, and there is a certain logic to it. Many people are afraid of creepy-crawly things, and just the feeling of the creatures crawling over the skin can be enough to terrify them. Alternately, the creatures may be the type that bite or sting, inflicting many shallow but painful wounds over a prolonged period of time without killing the victim. Many of these creatures are also venomous or poisonous, and that can cause effects of its own, provided the toxin isn't potent enough to kill or the victim isn't allergic.
Occasionally, other creatures can show up as well. Deliberately keeping them hungry so they'll be inclined to attack more aggressively or, in either case, commanding them with some form of Mind Control may figure in.
Compare Fed to the Beast and Snake Pit, which usually involves larger creatures and Eaten Alive, as well as Animal Assassin, where the animal is not used for torture but as a murder weapon. If it's a harmless prank rather than being used to mutilate someone, see Squirrels in My Pants.

- According to the Ancient Greeks, the Persians had a method of torture/ execution called "scaphism" whereby a victim would be bound to a shell made of two boats, fed and slathered with milk and honey, and left out in a body of water over the course of several days or weeks — however long it took to be devoured by insects and vermin.

As he explains to his increasingly-squeamish wife, the idea is to stick the open end of the cage against an orifice, then poke the rat's ass until it flees into the orifice, after which it gnaws its way out (Arthur is against torture, but he also would appreciate a quiet night's sleep).
- MythBusters has used a Downplayed form of this to test a related myth:

- The Creepypasta There's No Detention at my High School. Instead, They Send You to the Wasp Room has this as a school punishment.

- The Mawé people of Brazil have this as part of a warrior's initiation ritual. Young men must endure about ten minutes of wearing gloves with angry bullet ants, known for having the most painful insect sting in the entire world, sewn into them. Overexposure to the neurotoxins in these stings leave the men's arms temporarily paralysed and can cause tremors for the next several days. And in order to officially prove their manhood, they have to go through this process 20 separate times, which can understandably take years to complete.
