Why Do Cluster Flies Gather Around Windows?
Cluster flies are attracted to light and warmth, which is why they often gather around windows. They can easily become trapped between the window panes as they search for a way to escape towards the light outside. Some reasons why cluster flies are drawn to windows include:
Natural light: Windows are a primary source of natural light in any room. Flies are instinctively attracted to light sources, which is why you'll often find them buzzing around your windows.
Temperature fluctuations: Flies are ectothermic, meaning their body temperature depends on the surrounding environment. Windows tend to be warmer during the day, which attracts cluster flies seeking a heat source.
Access to shelter: Windows can provide small gaps and cracks that allow cluster flies to enter your home in search of a safe and warm place to hibernate during colder months.

Where Do Cluster Flies Come From?
Cluster flies are a species of slow-moving flies that lay their eggs in soil. Their larvae, known as maggots, attach to earthworms. As the weather cools, adult cluster flies seek shelter indoors to hibernate, which is when you're most likely to find them in your home. Here are some common sources of cluster flies:
Gardens and lawns: Cluster flies lay their eggs in soil, which means gardens and lawns are perfect breeding grounds for these insects.
Cracks and gaps in your home's exterior: As the weather turns colder, cluster flies search for warm, sheltered places to hibernate. They can enter your home through small cracks, gaps around windows and doors, or openings in your roof or walls.
Unsealed attic and crawl spaces: Cluster flies often find their way into unsealed attics and crawl spaces, where they can hibernate undisturbed throughout the winter months.
How to Keep Cluster Flies Away from Your Windows
To prevent cluster flies from invading your windows, try these practical solutions:
1. Seal gaps and cracks: Inspect your home's exterior for any gaps or cracks, paying close attention to areas around windows and doors. Use caulk or other sealants to close off any openings that could allow cluster flies to enter your home.
2. Install screens on windows: Fitting your windows with screens can help prevent cluster flies from entering your home while still allowing you to enjoy fresh air.
3. Use fly traps: There are various types of fly traps available, such as sticky traps or ultraviolet light traps, which can help reduce the number of cluster flies near your windows.
4. Clean regularly: Keeping your home clean can help deter cluster flies, which are attracted to decaying organic matter. Regularly clean your windows and window sills, and vacuum or sweep up any dead flies that may have accumulated.
5. Try natural repellents: Essential oils such as lavender, eucalyptus, and peppermint can act as natural repellents for cluster flies. Mix a few drops of essential oil with water in a spray bottle and lightly mist your windows and window sills to help deter these pesky insects.
