Why Do Flies Make Noise When They Die?

Fly buzzing is not a natural byproduct of the energy expended by flies during flight. Instead, some species of flies use this as a warning or form of communication. Fly buzzing also differs from other types of buzzing since some species of flies have greater control over their buzzing. Some species use a bypass method, contracting the muscles in the base of their wings, to create this noise.

During mating, flies create a buzzing sound with their wings. These mating noises are heard by hungry bats and may be the cause of violent death in some cases. Researchers at the Max Planck Institute for Ornithology in Germany found that bats were attracted to mating flies by their buzzing noise.

Adult fruit flies live for about two weeks and feed on polluted water and flower nectar. They generally live in shady areas. They can live in the shade next to drains or sinks and often cling to walls near plumbing fixtures. They also breed in sewage filter plants, and may be carried by the wind to nearby homes.

Although the sound of dying flies may be disturbing, there’s no need to panic. Taking steps to reduce your household’s risk of flies is the first step to preventing the problem. You can reduce the risk of flies spreading disease by ensuring your home is safe from animal carcasses.
