The Mole Rat is a mutated form of rat found in Fallout 3. They are one of the most common enemies for low-level characters in the game and they often travel in packs of three or more. They are very weak creatures, even for low-level characters, It's better to attack them with a Melee Weapon like a Baseball Bat or a Sledgehammer if you're new to the game and want to save your Ammunition.

During the quest you can get a Repellent Stick from Moira Brown, hitting a Mole Rat with this weapon will cause an allergic reaction which will result in their heads exploding a few seconds later. Hitting the Mole Rat a second time will make their heads explode instantly. The Repellent Stick only works on Mole Rats, it's practically useless on any other creature.
