One side quest, "A Good Scrub," in *Kingdom Come: Deliverance 2* unlocks a series of bathhouse-related quests requiring you to locate specific items. This guide details how to find something infested with fleas for Betty.
Pick Up ‘A Good Scrub’
Speak to the innkeeper in Kuttenberg about work. This will lead you to Betty, the bathhouse owner, located in the southeast part of the city. Accept her offer to find Matsek in Grund. Matsek is hesitant to be seen with the new bathhouse employees, so discreetly approach him in the courtyard. Speak to the three girls, mention Betty, and escort them back to the bathhouse.

Promote the Bathhouse
After returning the girls, help Betty advertise the bathhouse. Practice your sales pitch with her, then shout it out in the grain market, horse market, vintners’ street, and merchants’ street. Remember, this needs to be done during the daytime.
Clean Up the Bathhouse and Finish ‘A Good Scrub’
Clean the bathhouse before the alderman's inspection. Failing to complete this promptly will result in the bathhouse closure, preventing you from proceeding with "Ill Repute."
Finding Fleas for ‘Ill Repute’ in Kingdom Come: Deliverance 2
After a successful inspection, speak to Betty about the bathhouse's ongoing challenges. To influence the council's decision on the city's main bathhouse, you must persuade Councillor Naaz to leave the competing establishment.
Gather information from Meaty Mary, Katcha, and Little Lida to discover Naaz's dislikes. You'll need chamomile brew for the wine cask on the second floor of the competing bathhouse. Lida requires a noblewoman's dress (obtainable from a tailor) before revealing Naaz's fondness for fragrant oils. Alternatively, you can steal the oils from a cabinet on the third floor using lockpicking.
Katcha mentions the bathhouse's past flea infestation. To find a flea-infested item, head to Kuttenberg's east gate. Search the beggars' camp there for a flea-infested blanket.

Once obtained, return to the bathhouse and discreetly place the fleas in Councillor Naaz's laundry basket and the clean laundry basket.
Note: Completing just one of the three tasks might be sufficient to drive the councillor away, allowing you to finish the quest and progress to other quests, such as "Axe from the Lake."
