Keep it Simple: How to Get Rid of Fruit Flies
#1. Make a Simple Fruit Fly Trap
You will need a shallow bowl or jar, then add 1 cup of apple cider vinegar and a few drops of dishwashing liquid. The flies are attracted to the vinegar and land on its surface, but the dishwashing liquid breaks the surface tension of the vinegar, and the fruit flies fall in and drown. Place your trap in the area where you’ve seen the fruit flies.
#2. Use a Bottle of Leftover Wine or Beer
As with vinegar, fruit flies love the smell of wine (or beer). Leave out an open bottle with a little left over alcohol in the bottom. You can also add a few drops of washing up liquid to the wine. The thin neck will keep the flies trapped in the bottle.
#3. Use Some Rotten Fruit
Mash up some of your rotten fruit in a jar and cover the top with plastic wrap – poke some holes in the wrap which the flies will go into but find hard to come back out of.
