How to have successful fly control

Effective fly control requires identifying the juvenile stages of flies, primarily the larvae. This can be a challenging task, as different fly species prefer different larval habitats. For instance, house fly larvae are typically found outside, while drain fly larvae thrive in drains.

By contrast, the larvae of red-eyed fruit flies (Drosophila melanogaster) can be found under the trash bag in the trash can. The larvae of blow flies (Calliphoridae), which are attracted to decomposing wildlife, often can be found in the attic. Cluster flies (Polleniidae), whose larvae parasitize earthworms, are commonly found outside.

To effectively control flies, it’s essential to focus on the areas that are harboring the larvae of the species in question. By doing so, we avoid wasting time and chemicals on areas that are not conducive to fly development. While there’s rarely a silver bullet for fly control, focusing on the right areas can make all the difference.

Pay close attention to fly monitoring tools to identify the species present and their locations. After you have that information, it’s crucial to eliminate the conducive conditions to their larval success — and remove the larvae themselves.

In other words: Identify larvae habitat, focus on monitoring, and eliminate conducive conditions for successful fly control.
