P. are common scavengers. They are attracted by biological waste (or what they think of as biological waste). Especially slightly warm, squishy stuff and everything that might have a chance of turning slimy if left alone in the sun. P. gulp up waste and turn it into a foul smell. They are just dangerous if they nest in wounds.
How to fight it
Do not eat where you sleep and always put away food, bury the dead. Empty your trash often and clean away sticky messes at once. While P.s are not really dangerous, their smell deems of carelessness and might attract more dangerous monsters.gab
