Why flies keep smashing into windows, and the simple light-and-air trick that helps them find the exit

Flies repeatedly strike windows because their natural navigation instincts are confused by indoor environments. They are drawn to light, which usually signifies an open space for escape. Their compound eyes detect movement and light changes, not solid barriers. Airflow and light patterns guide their flight, which is less effective indoors. Understanding these behaviors helps in guiding them to an open exit.
