How to Get Rid of Fruit Flies in Your Bathroom

Fruit flies can be a nuisance in any home, but they seem especially bothersome when they invade your bathroom. Finding a group of tiny flies buzzing around the sink or shower when you’re trying to get ready for your day is certainly frustrating. Getting control of a fruit fly problem may take some diligent effort, but there are several effective methods you can use to banish them from your bathrooms.

Understanding Why Fruit Flies Are in Your Bathroom

Before getting into how to eliminate bathroom fruit flies, it’s helpful to understand what attracts them there in the first place.

They’re Attracted to Moisture and Organic Materials

Fruit flies seek out moist environments where they can breed and lay eggs. They’re especially drawn to the dampness around drains, sinks, and showers. Bathrooms offer plenty of moisture, making them a prime spot for infestations. These insects also feed on decaying organic materials. They can find food particles around drains or in trash cans. Even minute traces of leftover toothpaste, spit, or soap scum can sustain them. With a ready water source and food supply, bathrooms provide an ideal habitat.

Cracks and Crevices Offer Breeding Spots

In addition to moisture, fruit flies look for protected areas to breed in. They don’t need much space, as females can lay up to 500 eggs at a time in tiny cracks or crevices. Bathrooms provide plenty of potential breeding grounds, from gaps around pipe fittings to voids behind cabinets or under sinks. Once the larvae hatch, they start feeding and the cycle continues.

Sources of Infestation Spread Through the Home

Bathrooms are often centrally located, allowing flies to travel to and from kitchens, bedrooms and other areas of the house. If you have overripe fruit or produce sitting out, it can attract flies that then spread to search out your bathrooms. Plumbing and ductwork also connect bathrooms to each other and the rest of the home, giving flies easy access. Stopping an infestation requires removing breeding zones throughout the house.

Now that you know why fruit flies head for your bathroom, let’s look at proven techniques to get rid of them.

Eliminating Breeding Grounds

Fruit flies can reproduce rapidly, so a key step is eliminating breeding sources.

Clean and Dry All Surfaces

Spend time wiping down all counters, sinks, faucets, shower stalls, and tub surfaces. Look for any sticky spills or soap scum buildup to remove. Disinfect bathroom surfaces frequently to prevent future growth.

Be diligent about drying the sink and shower after use. Quickly wipe up any standing water on the floor as well. Don’t give flies any moist areas for laying eggs.

Clean Drains and Dispose of Organic Waste

Scrub bathroom drains weekly using baking soda and vinegar. This will remove food buildup inside drains where flies can reproduce.

Route out any clutter where food particles or soap scum can accumulate. Take the trash out regularly, especially if it contains any fruit scraps or peels. Promptly clean any bottles, cans or tubes that contain sugars or proteins.

Caulk Cracks and Crevices

Inspect around your bathroom pipes, vents, cabinets, and baseboards for gaps where flies can get in. Caulk or seal any narrow openings to eliminate breeding nooks. Foam sealants work well for plumbing gaps, while silicone caulk adheres better to smooth surfaces like tile.

Trapping Flies

Traps allow you to catch flies already buzzing about your bathroom. While less effective for extensive infestations, they work well at controlling smaller emergent populations.

DIY Fruit Fly Traps

It’s easy to make homemade traps with simple materials you likely have around the house:

  • Apple cider vinegar – Fill a bowl or jar partway with apple cider vinegar. Add a drop of dish soap to break the vinegar’s surface tension so flies sink.
  • Wine and dish soap – Similarly, you can use an inch or two of red wine topped with a drop of dish soap in a bowl.
  • Banana peel trap – Tape a peeled banana skin to the rim of a bowl, with the fleshy side facing in. Fill the bowl with about an inch of apple cider vinegar.

Place traps in out-of-the-way spots around the bathroom where you’ve seen flies. Replace the bait every few days as it degrades.

Purchased Traps

There are also ready-made fruit fly traps you can buy:

  • Sticky paper – Strips or rolls of paper coated with adhesive capture flies when they land on it. Hang strips along walls or above counters.
  • Bait stations – Plastic traps contain liquid lures like vinegar or pheromones. Flies enter through funnel openings and drown.
  • Electric zappers – Zappers use UV light and electric grids to stun flies. Models with vacuums collect the insect bodies.

When using store-bought traps, place them near breeding hot spots for maximum impact. Follow the manufacturer’s directions for changing bait and maintaining the traps.

Natural Pesticides

Natural insecticides made with oils or plant extracts can kill adult fruit flies on contact and deter larvae development. Spray these DIY mixes directly onto flies or breeding areas:

Essential Oils

Certain essential oils naturally repel or kill fruit flies:

  • Peppermint oil – Flies dislike the strong scent. Mix 20 drops of oil with water in a spray bottle.
  • Eucalyptus oil – Has insecticidal properties. Add 1/2 tsp into a sprayer of water.
  • Lemongrass oil – Contains citronellal compound toxic to flies. Mix several drops with water to spray.
  • Lavender oil – Offers repellent effects. Place drops onto cotton balls set around your bathroom.


You can also use regular household vinegar for pest control. Either spray it directly onto flies, or wipe surfaces with a vinegar cleaning solution.

Herbal Sprays

Make scented herbal sprays with antifungal and antibacterial properties:

  • Rosemary tea – Boil rosemary leaves in water. Transfer to a spray bottle once cooled.
  • Clove tea – Steep ground cloves in hot water for a day. Strain and add to a sprayer.

Apply these homemade repellent sprays anywhere flies congregate in the bathroom. Reapply after cleaning the area to prevent future infestations.

Preventing Bathroom Fruit Flies

While eliminating current fruit flies in your bathroom, also take preventative steps to avoid future swarms.

Store Produce Smartly

Keep fresh fruits and vegetables sealed up in the refrigerator. Throw away any spoiled or rotting produce. Avoid leaving produce sitting out on the counter where flies can get to it.

Take Out the Trash Frequently

Empty bathroom wastebaskets often so food particles don’t accumulate. Use bins with tight sealing lids. Any trash with fruit scraps should go straight to outdoor receptacles.

Fix Leaks

Dripping faucets or leaks allow moisture to collect, encouraging infestations. Repair any plumbing issues promptly.

Install Fly Screens

Add plastic fly screens over bathroom vents to prevent flies from traveling through ductwork. Screen windows as well to block outdoor populations from entering.

Use Smart Bathroom Designs

When remodeling, choose easy-to-clean surfaces like tile over grout. Seal concrete slab joints. Caulk bathroom additions meticulously to leave no gaps. Designing your bathroom with pest prevention in mind will cut down on future fly issues.

Frequently Asked Questions About Eliminating Bathroom Fruit Flies

Many homeowners battling bathroom fruit flies have similar questions when trying to remove an infestation. Here are answers to some of the most common queries.

Why do I suddenly have lots of small flies in my bathroom?

If you notice a swarm of tiny flies in your bathroom, they are most likely fruit flies. The most common causes are ripe produce left out somewhere in the home and moist conditions in the bathroom that allowed flies to breed. Even a few flies can multiply rapidly under ideal conditions.

How do you get rid of bathroom gnats permanently?

Eliminating fruit flies for good involves attacking all stages of their lifecycle. Remove any sources of moisture and food, such as drains, produce, or trash. Kill adult flies with traps, zappers, or sprays. Continue using preventive measures like fly screens and consider redesigning your bathroom with caulked seams to leave no breeding spaces.

Where do fruit flies hide in bathrooms?

Fruit flies congregate anywhere they can access food particles, moisture, and protected breeding spots. Check inside drains, under pipes, around windows and vents, in trash bins, on soap dishes, behind cabinets and mirrors, or near any openings. Basically anywhere warm, damp, and dirty.

What smell do fruit flies hate?

Strong scents from essential oils such as peppermint, eucalyptus, lemongrass, and lavender repel fruit flies. You can apply these diluted in water as spritzes. They may also dislike vinegar, citrus, and cloves. Avoid perfumes, lotions, or fragrant soaps that could attract flies.

How do you kill fruit fly eggs in drains?

It’s difficult to directly kill eggs, but you can create an inhospitable environment. Pour boiling water down bathroom drains to scald away eggs and larvae. Baking soda and vinegar loosens organic deposits. Clean drains prevent future egg-laying. Avoid powder drain cleaners that fruit flies can eat.

When should I call an exterminator for fruit flies?

If diligent sanitizing, trapping, and spraying aren’t eliminating an infestation after 2-3 weeks, contacting an exterminator is a good next step. They have commercial-grade insecticides and can hunt down hidden breeding zones you may have missed. Seek professional help for heavy infestations, flies coming up through pipes, or at the first signs of flies spreading through the home.

What chemicals kill fruit flies instantly?

Insecticide sprays containing pyrethroids like permethrin, tetramethrin, sumithrin, or resmethrin kill flies on contact. Pyrethroids interfere with insect nervous systems. Commercial exterminators may also use insect growth regulators to stop fly larvae from maturing. Avoid bug bombs, as they can just spread flies deeper into your home. Stick to targeted applications.


While tiny, fruit flies in your bathroom can become a seriously aggravating problem. Their ability to breed in miniscule cracks and ability to spread from other areas makes bathrooms a common trouble spot. Getting an infestation under control takes diligence to remove all traces of food, moisture, and access routes. Trapping flies helps reduce adults, while cleaning and sealing cuts down on breeding. Natural sprays or professional help provide additional weapons against stubborn fly populations. With a multi-pronged attack of these methods, you can eliminate fruit flies from your bathroom and prevent future invasions.

What Attracts Fruit Flies to Bathrooms?

Before diving into removal methods, it helps to understand what draws fruit flies into bathrooms in the first place:

Moisture and Standing Water

Fruit flies need moist environments to breed and thrive. They are attracted to the inherent dampness found around bathroom fixtures and drains. Leaky faucets, wet floors, and condensation provide ideal conditions.

Organic Materials and Food Sources

Fruit flies feed on decaying produce, fungi, and organic matter. Bathrooms offer plenty of microscopic food particles around drains, faucets, trash bins and other areas.

Cracks, Crevices and Small Spaces

Female fruit flies prefer to lay eggs in protected voids and gaps that provide shelter while larvae develop. Bathrooms provide an abundance of cracks in tile, small holes around plumbing, gaps under cabinets, etc.

Connection to Other Infested Areas

Centralized bathrooms place them near kitchens and trash areas, allowing flies to travel from primary food sources. Plumbing and ductwork also connect bathrooms to each other, spreading infestations.

Poor Sanitation and Lack of Disinfection

Bathrooms with chronically dirty drains, greasy buildup, cluttered spaces, and irregular cleaning invite fruit fly infestations by allowing ideal breeding conditions.

Now that you know why fruit flies migrate to bathrooms, let’s explore highly effective methods for removing an infestation from your own home.

Eliminating Breeding Grounds

Cutting off reproduction is critical when battling fruit flies. With optimal conditions, females can lay 500 eggs at once and the life cycle from egg to adult spans just 8-10 days. Stopping the breeding cycle requires:

Thorough Cleaning of All Surfaces

  • Scrub sinks, counters, toilets, tubs, showers, floors using antibacterial cleaners. This removes food sources and breeding spots.
  • Pay special attention to crevices, corners, U-bends, and any tiny spaces.
  • Wipe up spills immediately so moisture can’t accumulate.

Drain Cleaning and Maintenance

  • Pour baking soda and vinegar down drains weekly to clear away organic buildup.
  • Rinse with boiling water to kill eggs and larvae.
  • Use foam drain cleaners monthly to clear grease and create an uninhabitable environment.
  • Install drain covers to prevent future fly access.

Sealing Cracks and Crevices

  • Inspect plumbing, tiles, vents, woodwork, and windows for any gaps where flies can enter and breed.
  • Caulk or seal small voids with silicone, foam sealant, plaster, steel wool, etc.

Removing Food Sources

  • Take out bathroom trash frequently, especially any containing fruit waste.
  • Clean dirty dishes, overflowing bins, and counters that can collect particles.
  • Fix plumbing leaks that allow moisture to accumulate.

With breeding zones eliminated, the existing adult population will decline. Now let’s look at methods to trap and kill those pesky remaining fruit flies.

Trapping Techniques to Catch Adults

While sanitizing breeding sites is key for long-term control, trapping helps reduce adult fruit fly populations so you gain relief in the short term.

DIY Fruit Fly Traps

Homemade traps are an easy and effective option. They lure flies in with fermenting fruit, vinegar, wine or other attractants:

  • Bowl or jar with apple cider vinegar + dish soap
  • Wine bottle with small opening + vinegar/wine + dish soap
  • Funnel trap with paper cone pointing inwards
  • Rotting banana peel taped inside bowl + vinegar
  • Inverted soda bottle with small holes + bait

Place several around your bathroom and replace the bait every 2-3 days to keep trapping flies.

Commercial Traps

There are various pre-made traps you can purchase such as:

  • Sticky glue boards mounted on walls
  • Electric zapper traps with vacuums
  • Small bait stations containing pheromones or vinegar

Follow all product instructions for ideal placement and maintenance.

Fly Paper or Ribbon

Unfurl fly paper or ribbon strips coated with sticky adhesive where flies accumulate. The glue immobilizes flies when they land on it. Great temporary fix for events or as supplement to other methods.

Natural Pesticides

Natural insecticides made from common household items can kill fruit flies on contact:


Spray white distilled vinegar directly onto flies and breeding areas. Wipe surfaces with vinegar solution. Avoid apple cider vinegar, as this attracts flies.

Essential Oils

Oils like peppermint, lemongrass, eucalyptus, and clove have insecticidal properties. Mix a few drops into water and apply onto flies or spray in infested zones.

Liquid Dish Soap

Add a few drops of dye-free dish soap to water in a spray bottle. Spray directly onto flies for quick knockdown.

Herbal Teas

Steep rosemary, clove or cinnamon in hot water. Cool the strained tea and add to a spray bottle. Spray as natural fly repellent.

Rubbing Alcohol

Wipe down surfaces with 70% isopropyl alcohol solution to kill flies on contact.

Spot treat key infested areas with these DIY pesticide sprays for immediate fly control, while also eliminating breeding zones.
