Nectar Collecting for Fun and Profit

Nectar Collecting for Fun and Profit is a repeatable quest in Fallout 3.

Walkthrough
After resolving the fire ant infestation in Grayditch, Doctor Lesko will ask you to gather fire ant nectar so he can further research it. He won't take regular ant nectar. He will gladly reimburse you in the sum of 40 caps for every sample you bring him. Lesko is initially located in his underground lab in Marigold Station; he will eventually move back to his shack near the entrance of Grayditch after you complete Those!.

Prior resolving the conflict, fire ants can be found throughout Grayditch and the Marigold Metro tunnels; after the quest, they can only be found in the metro tunnels (if you have not killed them all, as they do not respawn even if the queen is left alive). The base percentage chance of the nectar being dropped by workers is 40%; for soldiers and warriors, 70%. These percentages are influenced by the player's Luck.

Bugs

 * Lesko will remain in the Metro Station caves with the ant queen. Because the queen attacks you on sight Lesko will begin "fleeing", unless you kill the ant queen, but the speaking options will be limited and an option about fire ant nectar will never appear.
