Fruit flies are a common household pest, but there are several ways to get rid of them using common household items.
One method is to create a trap using apple cider vinegar and washing up liquid. The vinegar attracts the flies, while the washing up liquid traps them. To make a trap, simply mix about a shot glass full of apple cider vinegar with some washing-up liquid and place it in a container with a narrow opening and a wide base. You can then add a funnel to the container, or leave it open, and simply watch the flies fall into it. Just remember to keep changing the liquid on a semi-regular basis.
Another method is to use a beer or wine trap. The flies are attracted to the smell of the beer or wine, and once they’re inside the trap, they can’t escape. To make a trap, simply fill a bowl or glass with beer or wine, cover the container with cling film, and seal the edges with a rubber band or tape. Then, poke tiny holes in the top.
Other ways to deter fruit flies include stopping watering your plants and introducing carnivorous plants. Fruit flies and other common pests, such as gnats, thrive on the fungus of houseplants so if you stop watering your plants, the soil will dry out causing the fungus to die. Carnivorous plants such as Venus flytraps are also a great natural way to get rid of fruit flies while adding aesthetic appeal.
