Against the background of guidelines on non-killing and developing ideas on the release of captured or domesticated animals, this study focuses on how vinaya (disciplinary) texts deal with dangerous and/or annoying animals, such as snakes, mosquitoes, and flies. Are there any circumstances in which they may be killed, captured, or repelled? Or should they be endured and ignored, or even protected and cherished, at all times? This paper discusses the many guidelines relating to avoidingand, if necessary, chasing awaydangerous and annoying animals. All of these proposals call for meticulous care to reduce the risk of harming the creature. In this sense, animals, such as snakes and mosquitoes, seem to be assured a better life in comparison with domesticated or hunted animals. This distinction reflects the somewhat uncomfortable balance that Buddhist monastics must achieve between respecting the life of individual sentient beings, including all animals, and adhering to social conventions in order to safeguard their position in society.
