Where to Find Them on Your Property?

You will find these types of flies on flowers or on larval food materials, such as decaying organic matter. Due to the fact that they are so unsanitary, they may transport disease-causing organisms to food materials. Some are parasitic and will attack other insects and arthropods. In or around structures you can find them inside drain pipes, inside of the trash, or around moist or rotting substances.
