Where are adult flies likely to congregate if there is a fly infestation due to rodent death?

Adult flies are often attracted to light, which explains why they tend to congregate in areas like windowsills where they can easily access natural light. This behavior is driven by their instinct to seek out light as a means of navigation and finding potential resources such as food and breeding sites.

In the case of a fly infestation prompted by rodent death, the presence of decaying organic material serves as a significant attractant. Flies are proficient at seeking out sources of decay where they can lay their eggs, and they will often gravitate towards lighted areas in close proximity to such resources. Thus, windowsills provide an attractive location for adult flies as they gather to feed or lay eggs.

Other locations, such as under the sink or in the attic, do not offer the same level of appeal for adult flies in search of light and interaction with their environment. While the attic might be where the rodent died, it lacks the light lure that adults find enticing. Consequently, windowsills are typically the most likely area for adult flies to accumulate in cases of infestation from a deceased rodent.
