Overview
Finish all quests involving the destruction of monster nests.
Chapter I
In this chapter you have to complete two pest control contracts. These two can be found on the notice board which is in front of the Flotsam Inn.
It is hereby announced that Commandant Bernard Loredo has posted a generous bounty for the extermination of the nekkers in the vicinity of the trading post. These monsters must be eliminated once and for all. The one to accept this job – and successfully complete it – will be rewarded with a bulging pouch of orens, and a priest will be paid to conduct prayers in our hero’s name for twenty eight days.
Louis Merse, Town Chancellor
If you want to complete this contract, you must get information about the nekkers first. You can do this by either killing enough nekkers (you can meditate after killing them, they spawn until their nests are destroyed) or you can read the book Nekkers in the Mist which can be bought from Einar Gausel in Flotsam.
You will need grapeshots to destroy the nests, you can buy the formula from Cedric. He is usually on the top of observation deck in Lobinden.
Locations of the nests are shown in the map, if you still have problems while finding them you can use your witcher senses to highlight them.
Faced with the insolence and bestial menace of the creatures known as endregas, and concerned for the people, Commandant Bernard Loredo has decided to post a bounty for the extermination of these creatures. The brave soul who permanently rids the area of this filth will receive a generous reward from the hands of Louis Merse and will be listed in the town chronicles as a true hero of Flotsam.
Louis Merse, Town Chancellor
Again, for this contract, you have to get information about the endregas. You can buy the book, Three Years Among the Endregas, from Einar Gausel in Flotsam or you can loot it from a cave you are sent for the Malena quest. Also you can kill enough endregas until you have enough information about them.

For this contract, you have to open all of the cocoons and destroy them. After that, you will encounter with the queen endregas. Killing the other endregas at the beginning, before you start destroying the cocoons will make the fight with the queen endregas easier.
You do not need any specific bombs for this contract. To kill queen endregas you can use traps and Yrden sign.
Chapter II
This part contains spoilers from the game.
In the Chapter II, you only have to do one of the two contracts. If you choose Roche’s path, you will get the Rotfiend contract. And if you choose Iorveth’s path, you will get the harpy contract.
It is hereby announced that the good King Henselt, Lord of Kaedwen, offers a bounty for the extermination of rotfiends in the vicinity of the camp. The monsters must be eliminated once and for all, by any method. The brave soul that rids us of the rotfiends will be rewarded by Proximo, and his feat duly recorded in the chronicles of Kaedwen.
You can get this contract from the notice board which is located in the Kaedweni camp, or you can ask the soldier who stands very close to the fighting arena if there are any jobs you can do.
You can get the book, The Horrors of War: Rotfiends, from Sambor. You can find him outside the Kaedweni camp. After you get enough information about the rotfiends, you are ready to burn the nine bodies to complete their contract.
Hear ye, hear ye – good folk of Vergen and all visitors! Since so many intrepid swords and champions of so many causes have gathered in Vergen, perhaps one would perform a public service by going to the harpy lair and exterminating the creatures once and for all? I promise a hefty reward and eternal glory as a monster slayer.

This one is a liitle bit more complicated than the Rotfiend contract, it is because you cannot complete this contract unless you continue on the Hunting Magic quest to reach some of the harpy nests.
You can get the contract from the notice board, and you can buy Harpies – Daughters of the Gale from Felicia Cori at the market. You may already have this book in your inventory, since it can be obtained in Chapter I as well.
You will need harpy traps to complete this contract, you can buy them from Haggard or you can buy the blueprint and ask any of the craftsmen to craft the traps for you. You will need seven traps, but you may want to have more than seven in your inventory in any case.
When you are at the old quarry, you will see the harpies. Do not kill them with your silver sword, instead arm one of the traps and wait for one of the harpies to grab it and carry it to its nest. It will destroy the nest once the harpy reaches there. Do this until you get rid of four of the nests, then you can kill the other harpies. Other three nests are behind the locked door which is also located in the old quarry. You will need to continue on the Hunting Magic quest for that door to be opened. When you enter the area behind the locked door, you can start using your traps again until you have all the nests destroyed. If the trap you put on the floor is not grabbed by harpies, you can take it back and arm it again. Do not put two traps at the same time.
Chapter III
There is only one contract in Chapter III, and whether you chose Roche or Iorveth does not matter.
Let it be known far and wide that the sorcerers gathered in Loc Muinne seek a brave soul to rid the city of gargoyles. These beings pose a threat to the guests arriving for the summit, therefore they must be removed by any means possible. The person or persons who successfully fulfill this contract will be rewarded by the venerable Bras of Ban Ard and receive the gratitude of the Brotherhood.
Gargoyles are one of the first monsters you are going to see once you enter Loc Muinne. They are used as guards and they protect the rune rooms. In this contract you will have to solve the puzzles of these rune rooms. This is the only way to get rid of the gargoyles.
You will need to buy the Runes of Power series of books to decrypt the magical signs. But other than that you do not need traps, or bombs for this contract. All you have to do is pressing the runes which are on the walls or on the floor, in the correct order.
