How Can Flies Get Through Screens?

During the summer and fall, you may worry about the presence of flies in your home. These bugs will be attracted to windows and can spread various illnesses and bacteria. Keeping your windows closed will help you keep these pests out of your home. However, sometimes flies will manage to get through your window screens.

The reason is simple: flies have a way of processing images, and they don’t have the complex vision that human beings have. Their compound eyes can’t tell the difference between two different images, so they have to rely on their legs and antennas to determine distance. As a result, they cannot see through the window and are easily hit.

Another way that flies can get into your home is by getting through cracks. These tiny cracks in your windows and doors allow them to squeeze through them. They also feed on warm air that is coming from inside your home. They can get through your screens if they can sense a stale air source, such as food.

Light is another problem for flies. Their eyes depend heavily on light. Because of this, they will cluster around glass windows. If they don’t get a chance to see the sunlight, they may end up gathering around the window and becoming disoriented. They will also become disoriented if they get hit by glass windows. They will eventually die as a result.
