How can I get rid of fruit flies/gnats in my kitchen?

Make sure that it is sealed to the jar and watch the fruit flies enter. The strength of the bait grows over time as it ferments. Also, the liquid has the double purpose of drowning and attacking.

4Let the flies sit in a bowl on the counter, with the surface tension broken. You can forgo using a funnel if you put a small bit of dish washing detergent in the cup with the vinegar and stir. The fruit flies are still attracted to the vinegar smell and the detergent traps them.

The detergent actually reduces the surface tension of the liquid, allowing the flies to more readily sink and drown; if the fruit flies fall in, it sticks to wings so they cannot fly. Use a little fruit or juice to help attract the fruit flies. Any small container with a teaspoon of cider vinegar, 2 tablespoons of water, and a drop of two of dish soap will attract and drown fruit flies.

To kill off the rest of the population, try pouring a cup or two of warm/hot vinegar (can be diluted with half water) down your kitchen and bathroom drains. Fruity smelling dish washing liquids (lemon, etc.) will attract fruit flies. There are even more ways to get rid of fruit flies, as explained in this section.

1Use screens to cover all of your doors and windows. This will prevent access from outdoors. 2Put a household fan near the most vulnerable areas (such as the fruit bowl).

Keep it blowing across the fruit. The flies cannot land in a cross wind. If you're doing this, put any bottle trap away from the fruit.

3Make a plastic Ziploc bag trap. Place a few slices of an apple inside a Ziploc bag.
