Place sticky fly traps around the house, particularly near windows and doors where flies tend to enter. These attract flies using ultraviolet light and trap or zap them upon contact.
Fill a bowl with apple cider vinegar and add a few drops of dish soap. The vinegar attracts the flies, and the soap breaks the surface tension, causing them to drown.
Commercial fly sprays can be effective for quick results. Spray directly on the flies or in areas where they gather. Mix essential oils (like peppermint, eucalyptus, or lavender) with water and spray around the house.
Ensure there are no exposed food items. Keep countertops clean, cover food, and store it properly. Empty garbage bins regularly and keep them sealed to prevent attracting flies.
Install or repair screens on windows and doors to prevent flies from entering. Use caulk or weather stripping to seal any cracks or gaps around windows, doors, and other entry points.
It is possible to use them to zap flies on the spot, which provides an immediate approach to the problem.
Flies are weak fliers and have difficulty navigating in strong air currents. Using fans can help keep flies away from specific areas in your home.
