* Failed spectacularly in ''Film/{{Serenity}}''. The Alliance attempted to use an engineered gas to make the violent populace very docile. [[GoneHorriblyRight The gas worked ''too'' well]]: most of the population became so apathetic that they just laid down and died. The others [[GoneHorriblyWrong became hyper-violent berserkers, known as the Reavers]].

* In the Destroy ending of MassEffect3, the trope is inverted, with the final weapon destroying all ''synthetic'' life, including the friendly ones, and leaving the organic life alone.

* Played with in the MultipleEndings of ''Videogame/MassEffect3''.
** In the Destroy ending, the trope is inverted, with the final weapon destroying all ''synthetic'' life, including the friendly ones, and leaving the organic life alone.
** In the Control ending, only the leader of the villains is affected, with the HiveMind now being controlled by the main character.
** In the Synthesis ending, both organic and synthetic life are combined into one hybrid race, making the war completely irrelevant.

* RobertRankin trumps H.G. Wells in his Victorian steampunk novel, ''The Educated Ape''. The ''War of the Worlds'' is referenced as having just been won, as per book, by the Martians not having thought to innoculate against Earth's diseases. But the devious Winston Churchill (a man who in life was an advocate of euthenasia, eugenics and chemical warfare) sent some of the captured Martian spacecraft back to them, loaded with volunteer crews of terminally ill humans, with every contagious diseases known to Man. A Mars cleansed of its higher life forms is then open to colonisation from the British Empire...

* ''TabletopGame/Warhammer40K''. [[http://wh40k.lexicanum.com/wiki/Virus_bombing Virus bombing]] is one of the ways Exterminatus (destroying a planet that has succumbed to TheCorruption or cannot be saved) can be carried out. As it destroys all life (and eventually, the ''atmosphere''), its use is rather limited.

* An erstwhile Alliance officer on ''Series/{{Firefly}}'' made his fortune using biological weapons to depopulate communities, then he looted their untouched valuables.

* Failed spectacularly in ''Film/{{Serenity}}''. The Alliance attempted to use an engineered gas to make the violent populace very docile. The gas worked ''too'' well: most of the population became so apathetic that they just laid down and died. The others became hyper-violent berserkers, known as the Reavers.

* An arc in ''Series/StargateAtlantis'' involved an attempt to develop a virus that would turn Wraiths into humans. They never managed to make its effects permanent or figure out an effective delivery mechanism. And their first test subject, "Michael", became a major recurring villain.

* ''Series/{{V}}''. In the mini-series, the human resistance develop a virus that only kills the aliens, driving them off the planet. When the aliens return for the later TV series, the virus can't be used again because increased concentration in the atmosphere will cause long-term mutations and sterility in the human and animal population.

* ZigZaggedTrope on the George Pal version of ''Film/TheWarOfTheWorlds'': it maintains the original ending of the Literature example below, but before the natural bacteria of Earth do the job, the military and the scientists were proposing to use bio-warfare (out of desperation, because nuking the machines didn't worked and the only option left was to try and see if it was possible to kill the Martians themselves). Unfortunately, the mobilization of the Martians towards L.A. means that the university the scientists are in needs to be evacuated, and the trucks that carry the equipment are robbed by desperate Angelenos who smash it all to make room (in the words of ScienceHero protagonist Dr. Clayton Forrester: "they sliced their own throats!").

* The Aschen from ''Series/StargateSG1'' use super bacteria as a means of destroying any opposition on any newly conquered planets. Once the weapon has killed all infrastructure they come in and make themselves look like heroes.

* The crux of the third and final ''Film/{{Blade}}'' film is the use of a virus that will kill all vampires everywhere, seemingly instantaneously.

* In ''Comicbook/LeagueOfExtraordinaryGentlemen'' it is revealed that the bacteria which killed the martians during the events of ''WarOfTheWorlds'' (see Literature below) was in fact a hybrid of Anthrax and Streptococcus developed by Dr. Moreau while working for the British Military.

* Used in the 7th season of ''Series/{{Supernatural}}'' by the Leviathans against the other monsters. they used a special chemical in fast food that would make the body's of humans who ate it to be deadly to all monster species, and this is a series where every on is a [[ImAHumanitarian Humanitarian]].

Just like GeneticEngineeringIsTheNewNuke, Biological/Chemical outbreaks are the new NukeEm.

Usually used in a GuiltFreeExterminationWar. Subtrope of FinalSolution (that trope doesn't specify ''how'' it gets carried out).
