->''"You got flies."''
-->-- '''Leonard Smalls''', ''Film/RaisingArizona''

In many works, especially horror movies, the first thing that indicates something going nasty is the arrival of [[TheSwarm flies, mosquitoes, wasps, maggots, and other creepy crawlies]]. Bonus points are earned if they are seen entering or emerging from a sleeping protagonist's mouth, nose, and ears. Generally linked to demons and ghosts, but might just be a symptom of something more natural like decomposition.

This trope has its roots in Beelzebub being "Lord of the Flies", and other Satanic connotations. Alternatively, it may be linked to the Ten Plagues.

See also TheSwarm and TheWormThatWalks, when the bugs are not only an indicator of evil, but are actually used as a monster directly, and EvilSmellsBad.
