* ''WesternAnimation/Chowder'' has Fuzzballs, which are literal balls of dirt.

* ''Literature/LivInTheFuture'' has "street mutants”, colorful geckos with cat fur and ears. They coexist alongside rats with glowing eyes and aren't regarded as the sort of animal one would rent out as a pet.

* ''Literature/ArtemisFowl'': Haven City is infested by swear toads, amphibians magically altered to constantly repeat obscenities. They began as a practical joke, got severely out of hand and now live in every damp corner of the city.

-> The only problems are the pests. Most places have mice or mosquitoes. We have... dragons.

* ''WesternAnimation/{{Onward}}'': {{Unicorn}}s, of all things, are garbage-eating, hissing pests in the vein of raccoons.

* ''Film/{{Bright}}'': Fairies are urban pests of animal intelligence, acting much like aggressive birds.

* ''Literature/HarryPotter'': Gnomes -- tiny, ugly, stupid and sharp-toothed humanoids -- take the role of outdoor pests in a manner similar to gophers, infesting the gardens of wizarding families.

* ''Franchise/MassEffect'' has the varren, jackal dog-like creatures that adapt well and breed rapidly, allowing them to quickly colonize other worlds, frequently becoming pests to locals.

* ''VideoGame/DwarfFortress'': Fantastic species such as pixies and fire snakes have been defined as [[https://dwarffortresswiki.org/index.php/DF2014:Vermin vermin]], meaning creatures that spawn randomly and spoil food, along rats and bats. The most unusual ones tend to live in evil biomes (which can hold demonic rats, pulsing bloodsucking insects and ghostly spiders) and the sometimes rather alien underground layers (which can produce infestations of crawling masses of fingerlike appendages or of the aforementioned snakes made out of fire).

* ''TabletopGame/MagicTheGathering'': The society on the plane of Kaladesh makes extensive use of complex, ornate {{Magitek}} powered by a substance known as ether. Kaladesh is also home to anteater-like {{gr|ipingAboutGremlins}}emlins, who feed on ether and eagerly use their sharp, strong claws and acidic drool to dig through rock and metal to get to it. Gremlins are thus the most destructive pests on the plane, and can cause immense damage to Kaladesh's technology and infrastructure. In a twist, however, the gremlins' feeding plays an important part in recycling ether back into the environment, and the extermination of gremlin colonies is causing real harm to Kaladesh's planer ecosystem.

* ''WesternAnimation/CloudyWithAChanceOfMeatballs'' has a FailureMontage of Flint's inventions. One of them was a project to splice bird traits onto rats, which quickly broke captivity and in the present have bred into a sizeable population. Besides snatching food, flocks regularly kidnap people into the sky before dropping them from great heights. They have some respect for Flint as their creator, enough to save his life in the climax, but not enough to stop doing what they're doing.

* ''Franchise/{{Tranformers}}'':

** In "[[Recap/StarTrekDeepSpaceNineS05E06TrialsAndTribbleations Trials And Tribble-ations]]", Worf says that Klingons view tribbles this way, since they endlessly eat and reproduce, to the point that they eradicated the tribble homeworld in the 23rd century. However, the episode ends with tribbles being reintroduced into the 24th century thanks to the crew bringing back at least one tribble from their trip to the 23rd century into the events of the TOS episode "[[Recap/StarTrekS2E15TheTroubleWithTribbles The Trouble With Tribbles]".

* ''Series/StarTrekDeepSpaceNine'' has Cardassian voles, six-legged creatures resembling very big rats. They infest the titular station's out-of-the-way crawl spaces and service areas. They are notoriously tenacious and hard to get rid of due to being ExplosiveBreeders.
** In "Trials And Tribble-ations", Worf says that Klingons view tribbles this way, since they endlessly eat and reproduce, to the point that they eradicated the tribble homeworld in the last 23rd century. Though, the episode ends with tribbles being reintroduced into the 24th century thanks to the crew bringing back at least 1 tribble from their trip to the 23rd century into the events of the TOS episode "The Trouble With Tribbles".

* ''WesternAnimation/TransformersPrime'' has Scraplets, tiny, vicious robotic life forms native to Cybertron that consume any and all metal in their path, including whole Transformers. They can be killed easily by luring them out into extremely cold temperatures.
** The original G1 ''WesternAnimation/TheTransformers'' cartoon often had the Transformers mention various fauna native to Cybertron, including ant-roids and retro-rats. We never actually '''see''' this native fauna, but at the very least they exist and some animal-form Transformers are hinted at having alternate modes based on them.

* ''Series/StarTrekDeepSpaceNine'' has Cardassian voles, six-legged creatures that infest the titular station. And they are a pain to get rid of.
