Did you know that a single female housefly can lay up to 600 eggs1 in her brief 30-day lifespan? Left unchecked, a small fly problem can quickly escalate into a full-blown infestation.
But don’t panic – you can win the battle against these pesky invaders with the right approach. Keep reading to learn 10 easy and effective ways to get rid of flies in your house for good.
1. Seal the Deal with Proper Exclusion
Keeping flies out of your home starts with good old-fashioned prevention. Ensure all your windows and doors have tight-fitting screens without any holes or gaps. Pay special attention to areas around pipes and electrical conduits – even the smallest opening can be an invitation for flies to enter.
For frequently used entrances, consider installing air curtains or fans. These create a barrier of moving air that can prevent flies from entering when properly installed. (ref)
2. Harness the Power of Plants
Nature has its own fly repellents, and you can use them to your advantage. Certain plants like basil and mint have been shown to repel flies and other pests. (ref)
Not only will these plants help keep flies at bay, but they’ll also add a pleasant aroma to your home or garden. Consider planting these natural fly deterrents near windows and entryways for maximum effect.
As an added bonus, many of these herbs can be used in cooking, giving you a dual-purpose solution to your fly problem.
3. Trap Them with Vinegar & Dish Soap
For a simple yet effective DIY fly trap, mix equal parts apple cider vinegar and dish soap in a small bowl, adding a pinch of sugar. The vinegar’s fermented smell attracts flies, while the soap traps and ultimately kills them by breaking down their digestive tract and cell walls.
Place these traps in areas where you’ve noticed fly activity. For best results, use a dish soap with a fruity scent to enhance the trap’s attractiveness to flies.
4. Light Up Their Lives (& End Them)
Electronic fly killers, also known as bug zappers, can be an effective tool in your fly-fighting arsenal. These devices use ultraviolet light to attract flies and then eliminate them with an electric shock.
They’re especially useful in enclosed spaces like egg packing rooms or waste handling areas.
For optimal results, place these units about 5 feet from the ground and away from windows and doors where flies might enter. While they may not completely control an infestation, they can significantly reduce fly populations in smaller areas.
5. Stick It to Them
Adhesive fly paper is a classic method that’s still effective today. These sticky traps can be hung from ceilings or placed in areas where flies frequently gather. The sweet, fragrant coating attracts flies, which then become trapped on the adhesive surface.
Remember to replace fly paper regularly, as it loses effectiveness when it dries out or becomes covered in dust. Depending on the severity of your fly problem, you may need to change these traps every few days to two weeks.
6. Embrace the Power of Cayenne
Flies aren’t fans of spicy sensations. Create a natural fly repellent by steeping cayenne pepper in hot water and transferring the mixture to a spray bottle. Use this spicy spray around doorways and windowsills to deter flies from entering.
While this method can be effective, keep in mind that the smell may be unpleasant to some people and the solution can stain if not properly diluted. It’s best to test this spray in an inconspicuous area first and reapply regularly as the effect wears off quicker than other methods.
7. Employ the Venus Flytrap
For a natural and fascinating way to control flies, consider the Venus flytrap. These carnivorous plants naturally attract and consume insects, including flies.
While they’re more effective outdoors, they can still help control fly populations inside if placed strategically.
Venus flytraps work by closing around flies when they land on the plant’s trap. The plant then secretes digestive fluids to break down the insect over 5 to 12 days.
8. Create a Soda Bottle Trap
Turn an empty plastic soda bottle into a fly trap with this clever DIY solution. Cut off the top third of the bottle and invert it into the bottom portion, creating a funnel effect. Fill the bottom with sugar water to attract the flies.
This trap works by allowing flies to enter through the funnel but making it difficult for them to find their way back out. Place these traps in areas with high fly activity, but be sure to empty and clean them regularly to maintain effectiveness.
9. Utilize Insecticide Baits
For more stubborn fly problems, insecticide baits can be an effective solution. These typically consist of a mixture of insecticide, sugar, and pheromone attractants.
They’re often applied as a paste on cardboard sheets or painted directly onto surfaces where flies commonly rest.
While originally developed for livestock units, some products are now labeled for use in waste sites as well. Always follow the manufacturer’s instructions and safety precautions when using any insecticide products.
10. Don’t Forget the Fly Swatter
Sometimes, the simplest solutions are the most effective. A good old-fashioned fly swatter can be a quick and economical way to deal with the occasional fly.
It’s especially useful for targeting individual flies that have made their way into your home.
For best results, approach flies slowly from behind and aim slightly behind where they’re sitting. Flies tend to jump backward when taking off, so this technique increases your chances of a successful swat.
