Just like the previous elements, the onion can prove valuable in combating the invasion of flies. Sliced or in decoctions, onions can be placed on top of cabinets or on window sills. They can also be rubbed on the edges of the frames, on the outside, to discourage intruders from entering.
8 – MILK, SUGAR, PEPPER: A FRUIT FLY TRAP
If you are bothered by fruit flies a lot, here is an old recipe for a sweet milky trap for them. This method was once used in England. As sugary substances attract fruit flies, this is the main idea of this fly trap.
Ingredients
½ liter of milk
¼ cup sugar
Black pepper – 4 tablespoons
Instructions
Pour the milk into a saucepan. Add the sugar and pepper.
Let the solution steep for 10-15 minutes.
Take a few shallow dishes like soup plates and pour some of this solution into each one.
Place these plates all around your house, especially where flies come most of the time.
Flies will be attracted to this solution and when they get close to it, they will suffocate and drown.
