Best Sprays to Kill Flies

Flies can spread illnesses to humans more readily than most people might expect.

Flies feed on both human food as well as germy and rotten material. The common house fly picks up disease-causing germs as they feast on garbage, rotting objects, and feces.

Those microbes that remain on the outside of a fly might survive for a handful of hours. However, viruses and bacteria that flies ingest may persist in the fly’s gut for several days. Transmission often happens when a fly regurgitates on spots people touch or directly on our food. This is why we’ve selected our favorite sprays to kill germy flies (and other insects) for your specific pest-eradication needs.
