There are several natural remedies and commercial products that people can use to spray around doors and other entry points to keep flies away. Here are some effective options:
Essential Oil Spray: Create a mixture of water and essential oils known to repel flies, such as peppermint, eucalyptus, lemon, or lavender. Fill a spray bottle with water and add a few drops of the chosen essential oil. Shake well before spraying around the door or any other fly-prone areas. Flies dislike the strong smell of these oils, making it an effective natural repellent.
Vinegar Spray: Flies are also deterred by the strong smell of vinegar. Mix equal parts of water and white vinegar in a spray bottle and apply it around the door frame and nearby surfaces.
Lemon and Cloves: Cut a lemon in half and stick several cloves into the flesh. Place the lemon halves near the door or windows to keep flies away. The combination of lemon and cloves emits a scent that flies find unpleasant.
Apple Cider Vinegar Trap: While not a spray, placing a small bowl with apple cider vinegar near the door can attract and trap flies. Add a few drops of dish soap to break the surface tension, causing flies to drown when they land in the liquid.
Fly-Repellent Plants: Consider planting herbs like basil, mint, lavender, or rosemary near your entryways. These plants have natural fly-repelling properties due to their strong fragrances.
Commercial Fly Repellents: There are various fly repellent sprays available in stores that are specifically designed to keep flies away from indoor and outdoor areas. These products often contain chemical compounds that act as effective insect repellents.
Remember to reapply these natural sprays regularly or as needed, especially after rain or heavy use of the door, to maintain their effectiveness. Additionally, keep your door and its surroundings clean, as flies are attracted to food residues and organic matter.
