Gnats may be invading your home for several reasons: food spills, over-watered grass, pipes leaking under the sink, garbage cans, or windows or vents with condensation. And once you have a single gnat, it can be hard to get rid of them because they breed so infrequently. But there is a simple solution and one without chemicals. Create a trap by mixing apple cider vinegar with a few drops of dish soap.
Another home-made trap is to pour leftover red wine into a jar. Mash up banana slices in a jar and cover the top with a plastic wrap. Pour bleach solution into the bathroom sink. Warning: do not mix bleach with ammonia. Another homemade solution is to fill a jar with a few spoons of green-apple soap liquid and dilute it with water. Keep it uncovered on a table and flies will be attracted to the smell and they will drown in the liquid. There are also many other household items that will draw gnats and flies, such as scented candles, fragrant oil burners, and potpourri.
