Why Do Flies Leave Marks on Windows?

If you have ever noticed flies on your windows, you may want to clean them to get rid of the flies that are causing the marks. Flies are small flying creatures that feed on the warmth and light of your home, so they may be attracted to your windows during the day. Fortunately, they aren’t harmful to your home or your health, but they are an unpleasant nuisance for homeowners.

If you are unsure of how to get rid of flies, you can buy a repellent spray. This spray contains an ingredient that repels the flies from your windows. These repellents are made to be waterproof, so you don’t have to worry about them falling on your glass windows.

Flies are highly active when there’s a lot of light. Light, temperature, and humidity increase their activity, and their eyes can’t process many different stimuli at once. If they happen to hit your window, they’re likely to be disoriented and confused about their next move.

Flies are also known for leaving their feces everywhere they land. Female flies prefer areas with dark, moist areas and usually deposit their eggs in trash, rotting food, and manure. They can also lay their eggs on countertops and trash bins. Afterwards, they will feed on trash and feces.
