Flit guns were in common use from about the late 1920s until the mid-1950s, which coincides almost exactly with The Golden Age of Animation. While Golden Age cartoons with flit guns are just reflecting contemporary technology, it's their use of such devices which established flit guns as the Universal Cartoon Symbol for Bug Sprayer and they've remained so long after the technology became obsolete in the real world.
- The name "flit gun" is a Brand Name Takeover, referring to the insecticide company Flit. Flit rose to prominence in the early 20th century due to a highly successful marketing campaign. The campaign used humorous cartoons, drawn by none other than a pre-fame Dr. Seuss, and spawned a popular Catch-Phrase, "Quick, Henry, the Flit!" So successful was the campaign that, at one time, crop dusters were nicknamed "flying flit guns".
- In The Wizard of Oz, the Cowardly Lion arms himself against the Wicked Witch with one.
- In Animal Crackers, Harpo uses one at the end of the movie. It knocks everyone out, including himself.
- In Labyrinth, Hoggle uses one of these against flying fairies.
- Used by Don Corleone's grandson in The Godfather.
- Willy Wonka uses one in Charlie and the Great Glass Elevator. Roald Dahl explicitly lampshades it as the kind you'd see "before Aerosol."
- A very early version appears in one of the Borrowers books; it takes the form of a bellows once used to stoke a fireplace, but with a mixture of herbs which got rid of pests.
- Buggs Zapper carries one of these in Where In Time Is Carmen Sandiego.
- In the Lizzie McGuire episode "When Moms Attack", animated Lizzie uses one during one of her interludes.
- Hawkeye and co. have one of these inside the Swamp on M*A*S*H.
- Ellery Queen: One of the comedians in the burlesque show uses a comically oversized one as a prop in his act in "The Adventure of Veronica's Veils". It was also the murder weapon; used to spray poison in the face of the Victim of the Week.
- The 2002 remake of Resident Evil 1 requires you to use one on the massive hornet's nest before grabbing the key beneath it.
- This is what your character uses in Donkey Kong 3, and in the Game & Watch game Greenhouse.
- Mr. Game and Watch went on to use the same bug sprayer for one of his attacks in the Super Smash Bros. series.
- Lots of time management games that involve either farming or flower growing will invoke this trope when fighting off bugs. There are a bunch of them on Big Fish Games.
- In Legend of the Crystal Skull, Nancy Drew must use one of these against wasps to gain access to a tree's fruit.
- Blood 2: The Chosen features one of these as a weapon, with a lit Zippo lighter attached to the top - primary fire shoots out extremely-acidic bug spray, secondary turns it upside-down to use it in the same manner as an Aerosol Flamethrower.
- Appears briefly in a cutscene in Spyro 2: Ripto's Rage!. A robotic farmer uses one of these to clear a swarm of bugs. A larger bug then shows up and uses its own cartoon bug sprayer on the farmer. And that's the last the player sees of the farmer, except for his hat.
- One appears in the apiary in BioShock, presumably as a smoker for the hives. It's actually an in-joke among the developers; the model was originally going to be a usable weapon that would fire the equivalent of the Insect Swarm and Enrage plasmids among other things.
- The 1934 Betty Boop cartoon Theres Something About A Soldier has an Army regiment battle giant mosquitos. The soldiers have middling success with giant swatters and peculiar artillery, until Betty Boop arrives at the front with a huge flit gun. It takes four men to pump it, but its gas cloud eradicates the mosquitos, for which Betty is given a hero's parade through town.
- Countless episodes of The New Adventures of Winnie the Pooh. The page image is from Winnie the Pooh and Christmas Too.
- That Tom and Jerry episode, "Trap Happy", with the Mouse Exterminator cat.
- Mickey Mouse uses one in "Mickey's Garden". In "The Worm Turns" he uses one to dispense Super Serum.
- My Little Pony: Friendship Is Magic: Applejack has one during the defense of Sweet Apple Acres in "Swarm of the Century".
- One of the common methods of attempting to dispatch the cockroaches in Oggy and the Cockroaches. Jack has a tendency to fill them with his own homemade pesticides, which often end up turning the odds even further in the favor of the roaches.
- The Joker uses one of these briefly in the first episode of The Batman to disperse his trademark Joker Venom.
- King Koopa used one to try and spray the Mario Bros. with pesticide in The Super Mario Bros Super Show! episode "Princess, I Shrunk the Mario Bros.".
- A Bullwinkle's Corner segment has Bullwinkle reciting "Morey Had a Little Lamb" (the name changed from Mary since Rocky, who is participating in the visual, is a boy). Bullwinkle's sheep costume has fleas that cause him to scratch frantically until Rocky applies bug spray to it.
Bullwinkle: So if you have a little lamb,
Just take a tip from me.
If it has fleas as white as snow...
Rocky: Just use some DDT!
- You can still find these in Ace and True Value hardware stores, but they're quite obscure.
- They're oddly linked with Nickelodeon, at least in toy form. The first instance was a small water-sprayer in a Happy Meal series; the second was a larger water-sprayer.
