Exterminator, at Your Service

Exterminator, at Your Service is a side quest in Book III. It is given by Morwen in Rockhammer.

Journal entry
"You have agreed to enter the Rockhammer Mine and find the Matron Roach near the winch room. Kill her, all her offspring and destroy any eff sacks you come across, then report back to Morwen in Rockhammer."

Walkthrough
Talk to Morwen in his office southeast of Rockhammer to receive the mission. From his office, head southeast and enter Rockhammer Mine. Make your way through the mine, pass the winch room with several giant gears, until the way splits into three different paths. There are five egg sacks in total. The northwest path leads to one and the northeast to another two. Follow the south path and turn left to reach the final two sacks, which is also where the Matron Roach can be found.

The egg sacks have high HP and every time they take damage, there's a chance a Bog Roach will spawn so it's recommended to use the Powder Kegs around the mine to destroy them. The Matron Roach has a ranged attack that does no damage but can blind the character, reducing their ToHit by half. You can lure it near a Powder Keg that has been placed next to the egg sacks to maximize the keg's usefulness. Once all the egg sacks have been destroyed, and the Matron Roach and every Bog Roach killed, return to Morwen to complete the quest and receive the reward.
