The first trick is based on the use of apple cider vinegar:
For better effectiveness, you can heat the apple cider vinegar as the heat releases the vinegar’s scent.
You’ll need a glass and a funnel-shaped rolled piece of paper, 12 cl of apple cider vinegar, a few drops of dish soap, and you can decide whether or not to add a piece of ripe fruit.
After heating the apple cider vinegar, pour it into the glass and add the drops of dish soap. The latter reduces the surface tension of the vinegar.
Then place the funnel in the glass, with a hole at the bottom to let the flies in. Once they’re inside, they can’t get out and will drown.
If they don’t drown, you can place the glass in the freezer for 20 minutes.
The Fruit Trap consists of the following ingredients: plastic wrap, a glass, ripe fruits, a toothpick, and soapy water.
Put the fruit pieces in the glass and seal it with the plastic wrap pierced with a toothpick.
Place it at strategic points in the house so the flies enter through the holes and can’t get out. Finally, immerse the glass full of flies in a container of hot soapy water for 10 minutes.
Two More Very Effective Methods
Red wine is another ingredient that strongly attracts flies. All you need is a small amount left at the bottom of the wine bottle to collect the flies. For them, it will be a death trap as they begin to drown in the remaining wine.
Alternatively, you can pour the wine into a container and then cover the glass with perforated plastic wrap.
The last trap is old and used by grandmothers. You need 50 cl of milk, 100 grams of brown sugar, and 50 grams of ground black pepper.
Put pepper, milk, and sugar in a pot and let it simmer slowly for 10 minutes. Then pour the mixture into empty plates and place them around the house.
When flies are attracted to the mixture, they get trapped and drown in the solution. To make it more effective, you can add one or two drops of dish soap to prevent flies from escaping from the surface.
Now, you just need to choose one of these tricks to apply against the flies roaming in your house and see the effectiveness for yourself.
