Fruit Flies in Bathroom-Why and How to Get Rid & Prevent

Fruit flies are minuscule brown flies with large eyes that make their way into the bathroom. Damp organic matter and surfaces present in the bathroom is what attracts them. To get rid of fruit flies, you can use vinegar or even set up DIY Traps and fruit traps. Read on to get more details.

What are Fruit Flies?

Fruit flies are small brown flies that have large red googly red eyes, although some can have dark-colored eyes. Their thorax is tan, and their abdomen is black with a gray underbelly, fruit flies, however, tend to have an overall tan appearance.

Their antenna has feathery bristles coming off it. They love feeding on rotten fruits and vegetables and often make their way into the bathroom, mainly because they are attracted to water and damp places and the bathroom is one of the places.

Why do I have Fruit Flies in my Bathroom?

Fruit flies are common in bathrooms because they love moisture. A bathroom drain is full of moist organic matter, making it the perfect place for these fruit flies to reproduce.

Since female flies can lay dozens of eggs each day, what started out as a few flies can quickly become hundreds of flies. This leads to an influx of fruit flies in your bathroom drain.

Plumbing facilities that collect moisture, particularly sinks and shower drains, attract fruit flies.  The warm, moist environment encourages the flies to settle and breed.

Since the bathroom drains aren’t easily accessible by homeowners, the eggs and larvae often remain undisturbed. The fruit flies will only keep multiplying until you contact professional drain cleaning services.

What Attracts Fruit Flies to the Bathroom?

Decay, debris and decomposing matter within the bathroom sinks and drains is what attracts fruit flies. Bathroom sink drains are notorious breeding grounds for fruit flies. When you have a clogged sink with build-up, it creates a dirty, damp environment for the fruit flies to prosper.

A lack of plumbing maintenance may increase the likelihood of fruit flies appearing in your bathroom. Leaky faucets, broken pipes, and clogged drains are all common causes of fruit flies.

If you notice an inexplicable puddle of water under the sink, you probably have a leak somewhere in your plumbing.

Food and fruit remnants left on the bathroom floor or trash can be a cause of fruit flies in the bathroom. Maybe you left your glass of wine in the bathroom or spilled some wine and forgot to wash it off, this smell attracts them.

Or perhaps you were eating an orange when you were taking a bath in the bathtub and forgot the orange peels on the floor, then the scent may attract them.

In case you have hot showers then the warmth from the steaming water might be the cause of fruit flies in your bathroom. They like warmth and it attracts them.

Where do Fruit Flies come from in the Bathroom?

Because these insects are so tiny, they can get in through window screens or crevices around windows or doors.

Fruit flies can also be introduced into your home by purchasing fruit, vegetables, or poorly sealed jarred or bottled goods that are already infested with fruit flies or their larvae.

They are attracted to fruits, hence may stick on them as they are in the house and then move into the bathroom as it has better conditions for their breeding.

How to Get Rid of Fruit Flies in the Bathroom

Fruit flies can be a nuisance in the bathroom since they fly and the buzz can be very irritating. They can also cause and spread bacteria which is a health hazard and for this is why they should be dealt with immediately they are seen.

There are several ways of getting rid of fruit flies in your bathroom. They include the following:

DIY Traps

Making DIY Fly Traps is a great way to get rid of fruit flies in the bathroom.

They work by trapping the flies in a sticky substance, which prevents them from escaping. As the flies try to escape, they become stuck in the trap.

Vinegar Trap

The most popular fruit flies trap is a vinegar trap, which is simple and cost-effective to create.

To make this trap follow the following steps:

  1. Place a few tablespoons of apple – cider vinegar in a bowl
  2. Add a few drops of dish soap to the bowl with vinegar in it
  3. Add a tablespoon of sugar to the bowl
  4. Stir the mixture gently.
  5. Set your bowl in an area where fruit flies are prevalent, in your bathroom like near the bathtub or even the sink.
  6. The sugar and apple-cider vinegar combination is responsible for attracting the fruit flies, and the dish soap is for trapping the fruit flies and eventually causes them to drown.

If you cannot access apple-cider vinegar presently, you can use a combination of red wine and dish soap to create a similar fruit flies trap. If your fruit flies infestation is particularly intense, you may want to set out a few bowls of this wine trap mixture around the house.

Yellow Food Coloring Traps

To make the trap, do the following:

  1. Mix some apple – cider vinegar with a few drops of dishwashing detergent and yellow food coloring in a cup. Apple cider smells like fruit, hence will attract the fruit flies.
  2. Place a layer of cling film across the top of your container, keeping it in place with an elastic band. Make a few small holes in the film.
  3. The yellow coloring and the acidic scent of the apple-cider vinegar which mimics rotting vegetation attracts the fruit flies, and then they get trapped inside the container.

Fruit Trap

This method also works well. For this method, do the following:

  1. cover a jar of overripe fruit with plastic wrap and poke small holes into the wrap’s surface.
  2. The fruit flies may smell a food source and enter the jar, becoming trapped.

There is also another way to make a fruit trap. For this, do the following:

  1. place some fruit skins in a disposable container, or you can also use a few tablespoons of beer or wine to attract the fruit flies.
  2. Wrap the container with a cling film layer, sealing it with an elastic band.
  3. Poke a few small access holes and then set it up in your bathroom.
  4. If you do not have a beer, you can add a few teaspoons of sugar, yeast, and water, as this may mimic the fermentation process that attracts fruit flies.

Candle Trap

Light also attracts fruit flies just like other insects, and hence a candle trap can be used to get rid of them.

Using this method, follow the steps given below

  1. Place a candle in a candlestick and fill the holder partially with water.
  2. Light the candle and turn off the lights.
  3. The fruit flies flock to the flame and be burned or may fall into the water and drown. 
  4. When using this method, make sure you put out the candle flame before going to bed to prevent a fire outbreak.

  2. Fruit flies sit over them and get stuck.

Use Potato Chunks

Potatoes are very attractive to fungus fruit flies larvae, making this a good method of getting rid of fruit flies.

This method is well suited for someone who has potted plants or indoor plants in the bathroom.

  1. Place raw potato chunks in the soil around the earthen pots. This trick will trap the larvae away from plant roots, as they are attracted to the potato.
