Repellent Stick

The  is a unique quest-related melee weapon found in Fallout 3 designed to ward off mole rats, though it unintentionally has a far more fatal effect on them. It is a simple stick, the tip of which is soaked with an unknown green chemical compound created by Moira Brown in her lab.

Location
This item is obtained from Moira Brown at Craterside Supply in Megaton during the quest The Wasteland Survival Guide.

Characteristics
The Repellent Stick is a simple wooden stick with mole rat repellent on it. The stick is exceptionally effective against mole rats, as one hit causes an allergic reaction on mole rats, causing their bodies to smoke and their heads to explode in five seconds, while a second hit will cause the explosion to happen instantly. This is probably due to the stick triggering the 'genetic kill switch' put in the mole rat species during their genetic engineering. Do not be fooled by what Moira says when you first get this stick, as it's an experiment gone wrong. Moira will exclaim "Poor little mole ratties!" when she realizes it does more than chasing the mole rats away.

If you use the stick on any other creature other than a mole rat, it will still cause the "smoking" effect, though it won't cause them to explode.

Bugs

 * Because it is a quest item, if you convince Moira Brown to give up on the book, buy it back from her, or pick the lock on her desk and take it after completing the quest, you are unable to drop it. To drop it, open the console and type "player.removeitem 0002D3B7 1"
 * In most add-ons where your items get taken away, i.e. Mothership Zeta, The Pitt and Operation: Anchorage, you will still have it.
 * It can also be used in Tranquility Lane if hotkeyed beforehand.
