King's Landing grew too fast and without any planning in the early days of the rule of the Targaryen dysnasty over Westeros. As a consequence, mud, manure, and nightsoil were everywhere in the city. King Jaehaerys I Targaryen greatly improved the salubrity of the streets by a series of construction projects he ordered during his reign. Despite Jaehaerys's efforts, nightsoil is still thrown in the street from windows two centuries and half later, leaving a stink in the city, and its gutters.

Cersei Lannister complains to the High Sparrow about the night soil the sparrows and their animals have produced around Blessed Baelor's statue in the plaza outside of his Great Sept. The High Sparrow retorts the holy place was only befouled by the execution of Lord Eddard Stark ordered by her son.
At the Second Siege of Riverrun, Edwyn Frey suggests that Riverrun will fall, if Ser Brynden Tully dies. Thus he proposes to stage an attack on the castle, then target the Blackfish with archers whose arrows will be smeared with night soil when he comes to lead the defense. The proposal is dismissed by Lord Karyl Vance and Ser Lyle Crakehall, who consider such an approach ignoble.
A Dance with Dragons
Lord Commander Jon Snow visits the Free folk camp at Mole's Town, and reflects on the smell of unwashed bodies, soiled clothing, nightsoil and urine. Jon disapproves of his men making japes about the "stench of the savages", however.
The morning air was thick with the old familiar stinks of King's Landing. She breathed in the scents of sour wine, bread baking, rotting fish and nightsoil, smoke and sweat and horse piss. No flower had ever smelled so sweet.—thoughts of Cersei Lannister
