Creating Your Fly Trap
Prepare your container: Choose a cup, jar, or small bowl. The wider the opening, the easier it will be for flies to enter.
Prepare your bait: Mix your chosen bait solution directly in the container. For example, if using the milk and sugar option, combine the milk and sugar in the container, then heat it slightly (in the microwave or on the stove) until the sugar dissolves. Allow it to cool before proceeding.
Add dish soap: Add a few drops of dish soap to your bait mixture and stir gently. The soap breaks the surface tension of the liquid, causing flies to sink and drown rather than land on the surface.
Cover the container: Stretch plastic wrap tightly over the top of the container and secure it with a rubber band to ensure it stays in place.
Create entry points: Use a toothpick or fork to poke several small holes in the plastic wrap. These holes should be large enough for flies to enter but small enough that they’ll have difficulty finding their way out.
Optional enhancement: For extra attraction, you can smear a small amount of honey or sugar water around the holes to lure flies to the entry points.
Placement Tips for Maximum Effectiveness
Indoor use: Place traps near windows, fruit bowls, garbage cans, or other areas where you’ve noticed fly activity.
Outdoor use: Position traps away from seating areas, as they will initially attract flies before capturing them. Good locations include near garbage bins, compost piles, or garden areas with rotting vegetation.
Multiple traps: For severe infestations, place several traps around your home or yard for better coverage.
Why This Works
Each bait option works for slightly different reasons:
Milk and sugar: The milk begins to ferment, creating an odor that flies find irresistible. The sugar enhances the attraction.
Apple cider vinegar: The acetic acid in vinegar mimics the smell of fermentation that attracts fruit flies and some house flies. The added sugar increases its effectiveness.
Wine or beer: The fermenting alcohol scent is particularly attractive to fruit flies and some species of house flies.
In all cases, the dish soap is crucial as it breaks the surface tension of the liquid. Without it, flies could potentially land on the liquid, drink, and fly away. With the soap added, they break through the surface and drown.
Specialized Traps for Different Types of Flies
Different species of flies are attracted to different baits. Here’s how to target specific types:
For Fruit Flies
Fruit flies are most attracted to fermenting fruits and sweet substances. The apple cider vinegar or wine bait works exceptionally well for them. You can enhance either of these options by adding a small piece of overripe fruit, such as a banana slice or strawberry.
For House Flies
House flies prefer slightly more pungent odors. The milk-based bait is particularly effective for these common pests. For enhanced attraction, you can add a tiny amount of fish sauce or a small piece of raw meat to the trap (though this will create a stronger odor).
For Drain Flies
If you’re dealing with drain flies (those small, moth-like flies often found in bathrooms), place traps near drains and use the apple cider vinegar solution. Additionally, pour a mixture of equal parts baking soda and vinegar down the affected drains, followed by boiling water after 30 minutes.
Maintenance and Disposal
For continued effectiveness:
Check traps every few days
Replace the bait solution when it becomes filled with flies or loses its potency (typically every 5-7 days)
When disposing of the trap, seal it in a plastic bag before placing it in the trash to prevent any surviving flies from escaping
Alternative Solutions for Comprehensive Fly Control
While these homemade traps are effective, combining them with other methods creates a more comprehensive approach to fly control:
Prevention: Keep food covered, take out garbage regularly, and clean up spills promptly.
Repellent plants: Grow basil, lavender, or mint near windows and doors, as flies dislike their scents.
Essential oils: Place a few drops of eucalyptus, lavender, or lemongrass oil on cotton balls and place them in areas where flies congregate.
Fly screens: Install screens on windows and doors to physically prevent flies from entering.
When to Seek Professional Help
While homemade traps are effective for moderate fly problems, certain situations may require professional intervention:
Persistent infestations despite multiple control methods
Flies appearing in unusual locations (like inside walls)
Sudden appearance of large numbers of flies, which may indicate a hidden source such as a dead animal
