Where are you most likely to find a significant phorid fly infestation?

A significant phorid fly infestation is most likely to be found in animal raising facilities due to the specific environmental conditions that these areas provide. Phorid flies are commonly associated with decaying organic matter, including animal waste, which is prevalent in settings where animals are housed or raised. These flies thrive in environments with high moisture and abundant food sources for their larvae, such as the decomposing organic materials found in animal facilities. This makes such locations conducive to phorid fly populations, leading to potential infestations that can affect animal health and overall facility sanitation.

In contrast, while mausoleums and hospitals may have some organic material, they do not typically provide the same ideal breeding conditions as animal raising facilities. Offices are not environments where phorid flies are likely to thrive, as they lack the necessary sources of food and moisture that support these pests. Therefore, the specific characteristics of an animal raising facility make it the most probable location for a significant phorid fly infestation.
