thumb|right|400px|Overview thumb|[[Karka Hatchlings — single entities are hiding]] Lion's Arch Exterminator is an Explorer achievement that requires the player to find fifty Karka Hatchlings throughout Lion's Arch.

240px|thumb|right|Turl Sharptooth's location Find Turl Sharptooth in the Commodore's Quarter, and talk to him to obtain one of his special rifle to deal with the Karka Hatchling infestation. After you accept the rifle, stop and look on the wall to his left - before you shoot it, review the comments below on appearance and sound of the hatchlings. The rifle is a bundle, and stays equipped as you move both while underwater and swimming on the surface (i.e. it can be used when the skillbar is hidden, but remember what button is shoot (default is "1")). If you have mounts, you can mount and dismount without losing the rifle. It is also possible to waypoint teleport within Lion's Arch and not lose the rifle bundle. Should you lose the rifle, like by dropping the bundle, by dying, by disconnecting, or by leaving Lion's Arch, you can get another by speaking to Turl Sharptooth again. This achievement is a mix between a jumping puzzle and scavenger hunt which gets your character into more remote and odd corners of Lion's Arch. There's times when your character may get jammed in between landscape features and not be able to get out, unless with a teleport or by using a waypoint (keep this in mind as it may save a lot of stress). This is an achievement where your settings can ease or increase difficulty. If you've set your camera show the widest field of view, your character's body may sometimes get in the way. If you've set the game's level of detail to low for performance reasons, then you may need to change your settings to make terrain details more defined, in order to make it easier to see the hatchlings from the environment. Achievement progress can be tracked on the "Lion's Arch Exterminator" achievement page in the "Explorer" sub-category in the "General" category in the achievement panel.

Even though there is a karka hatchling in Farshore Ward (hidden behind rocks in front of the bridge leading to Deverol Gardens), it doesn't make any sound nor can it be killed with the rifle. It is unknown whether it was intended to be part of the achievement or if its presence here is purely for lore's purposes. Another karka hatchling that doesn't make any sound is located inside the underground cave bar at the Western Ward. It resides behind some rocks where a passed out Citizen is lying on the ground.
