how to get rid of flies quickly

Introduction

When flies invade your home, they’re more than just annoying. They can spread bacteria, contaminate food, and make your space feel dirty. The good news: you can get rid of flies quickly with the right combination of cleaning, traps, and prevention.

This guide explains why flies appear, how to remove them fast using proven methods, what natural remedies actually work, and how to stop them from coming back.

Why Flies Appear

Flies don’t show up at random. They’re attracted to specific conditions in and around your home. Understanding what draws them in makes it much easier to get rid of them—and keep them away.

Common reasons flies invade your home

• Food left out: Uncovered food, dirty dishes, fruit bowls, and pet food attract houseflies and fruit flies.
• Garbage and compost: Open trash cans, overflowing garbage, and compost bins are prime breeding sites.
• Moisture and drains: Standing water, leaky pipes, and dirty drains can attract drain flies and gnats.
• Animal waste: Pet litter boxes, outdoor pet feces, and bird droppings draw flies quickly.
• Rotting organic matter: Overripe fruit, rotting vegetables, and decaying plant material provide food and breeding sites.
• Easy entry points: Open doors, damaged window screens, and gaps around windows or vents let flies in.

Types of common household flies

Knowing what you’re dealing with helps you choose the right method:

• Houseflies: Medium-sized, grey flies often found near food, garbage, and pet waste.
• Fruit flies: Tiny brownish flies that hover around fruit, wine, vinegar, and damp organic residue.
• Drain flies: Small moth-like flies that live and breed in sink, shower, and floor drains.
• Gnats and fungus gnats: Very small flies often associated with overwatered houseplants and damp soil.

5 Proven Methods to Get Rid of Flies Quickly

For fast relief, use several methods at the same time: remove what attracts flies, kill the ones you see, and block their entry points.

1. Eliminate what’s attracting them (most important step)

Before anything else, remove the food and breeding sources. Otherwise, new flies will appear as fast as you kill the old ones.

• Secure all food:
  • Cover food immediately after serving.
  • Store leftovers in sealed containers in the fridge.
  • Keep fruit in the refrigerator or covered with a mesh food cover.
• Clean kitchen surfaces thoroughly:
  • Wipe countertops, stove, and table after each meal with a multipurpose cleaner or vinegar solution.
  • Clean up spills and crumbs as soon as they happen.
  • Don’t leave dirty dishes in the sink overnight.
• Handle garbage correctly:
  • Use trash cans with tight-fitting lids.
  • Take out kitchen trash daily, especially in warm weather.
  • Rinse out food containers before tossing them if they’ll sit for more than a day.
• Fix moisture issues:
  • Repair leaky faucets and pipes.
  • Wipe up standing water immediately.
  • Dry sinks and tubs after use if you have persistent drain fly issues.
• Remove outdoor attractants:
  • Pick up pet waste daily from the yard.
  • Keep outdoor trash cans closed and clean.
  • Don’t leave open containers of food or drink outside.

2. Use targeted traps (fast and effective)

Traps work quickly and can drastically reduce fly populations within hours or days.

Sticky fly traps

• How they work: Flies are attracted to the strip and get stuck on the adhesive surface.
• How to use:
  • Hang flypaper strips near windows, doors, or areas where flies gather.
  • Keep them away from direct drafts; gentle airflow helps attract flies.
  • Replace strips when they’re covered or dusty.
• Best for: Houseflies and other flying insects indoors.

Commercial fly traps and bait stations

• How they work: Use attractants (scent or food-based) to lure flies into a container they can’t escape from.
• How to use:
  • Follow the instructions on the package carefully.
  • Place outdoor traps at least 15–20 feet away from doors and windows to pull flies away from your house.
  • For indoor traps, place them near problem areas but away from food prep surfaces.
• Best for: Heavy fly infestations outdoors or in garages and sheds.

DIY jar traps

• Basic method:
  • Use a jar or cup and add a small amount of bait (e.g., apple cider vinegar, fruit scrap, or sugary water).
  • Cover the top with plastic wrap and secure it with a rubber band.
  • Poke several small holes in the plastic; flies enter but struggle to exit.
• Best for: Fruit flies and houseflies around kitchens and trash areas.

3. Attack breeding sites (stop flies at the source)

To truly get rid of flies, you must destroy their breeding sites. This prevents new flies from emerging every few days.

For drain flies and gnats

• Clean drains deeply:
  • Remove and clean sink stoppers and strainers.
  • Scrub the inside of the drain with a stiff brush if accessible.
  • Pour a mixture of hot water and dish soap down the drain to break up organic film.
• Use a baking soda and vinegar flush:
  • Pour 1/2 cup baking soda down the drain.
  • Add 1 cup white vinegar. Let it foam for 10–15 minutes.
  • Flush with a full kettle of boiling water.
• Dry out drains overnight:
  • Use the drain in the morning and early evening only.
  • At night, dry the sink basin and cover the drain with a stopper or tape for a few days to block adult flies.

For fruit flies

• Throw away overripe or damaged fruit and vegetables.
• Empty and wash recycling bins that held bottles, cans, or jars with sugary drinks.
• Wipe sticky residues on counters, shelves, and inside cupboards.
• Clean under appliances where bits of food or spills may have collected.

For houseflies outdoors

• Clean up animal waste daily.
• Keep compost covered and turn it regularly to reduce exposed rotting material.
• Move garbage cans farther from doors and ensure lids seal well.

4. Use mechanical control: swatters and vacuums

If you need immediate results for a few flies, mechanical methods are efficient and chemical-free.

• Fly swatter:
  • Use a traditional or electric fly swatter to kill visible flies on surfaces.
  • Approach flies slowly from behind; they take off forward and upward.
• Vacuum cleaner:
  • Use a handheld or hose attachment to suck up flies resting on windows or walls.
  • Empty the vacuum canister or bag promptly afterward.

5. Consider insecticides (use carefully and sparingly)

Chemical sprays can kill flies quickly but should be used as a last resort, especially around food and pets.

• Aerosol fly sprays:
  • Use only in well-ventilated areas and follow label instructions.
  • Remove or cover food, dishes, and utensils first.
  • Keep children and pets out of the area until it’s safe to re-enter.
• Residual sprays for outdoor use:
  • Apply to outdoor walls, garbage areas, or around door frames where flies rest (if the product is labeled for that use).
  • Never spray inside near food prep zones unless specifically allowed on the product label.
• Important: Always prioritize cleaning, trapping, and exclusion. Overuse of insecticides can be unsafe and may not solve the root problem.

Natural Remedies to Get Rid of Flies

If you prefer to avoid chemical sprays, several natural methods can help reduce flies effectively.

1. Apple cider vinegar traps (for fruit flies)

• What you need: Small bowl or jar, apple cider vinegar, a drop of dish soap.
• How to do it:
  • Pour 1–2 cm of apple cider vinegar into the container.
  • Add a drop of dish soap and gently swirl (this breaks the surface tension so flies sink).
  • Leave the bowl uncovered near the infestation area.
• Result: Fruit flies are attracted to the vinegar, land in it, and drown.

2. DIY sugar-water traps

• What you need: Jar or plastic bottle, water, sugar, a piece of fruit peel (optional).
• How to do it:
  • Mix water with sugar until dissolved (sweet but not syrup-thick).
  • Pour into the container to a depth of about 2–3 cm.
  • Optional: add a piece of overripe fruit for extra attraction.
  • Cover with plastic wrap and poke small holes, or create a funnel top using a cut plastic bottle.
• Best for: Houseflies and fruit flies around kitchens and garbage.

3. Essential oils as repellents

Some scents repel flies without harming people or pets (when used correctly and not ingested).

• Effective oils: Eucalyptus, lavender, peppermint, lemongrass, citronella.
• How to use:
  • Mix 10–15 drops of essential oil with 1 cup of water and a teaspoon of witch hazel or rubbing alcohol in a spray bottle.
  • Shake well and spray around doorways, window frames, and areas where flies gather.
  • Do not spray directly on food or food-preparation surfaces.
• Note: Some essential oils can irritate pets; avoid spraying directly on pet bedding or where they lick.

4. Herbs and plants that discourage flies

• Helpful plants: Basil, mint, lavender, bay leaves, and rosemary.
• How to use:
  • Place potted herbs near doorways, windows, and outdoor eating areas.
  • Crush a few leaves occasionally to release more scent.
• Note: These plants help repel flies but won’t eliminate a severe infestation on their own.

5. Natural drain cleaning

• Use the baking soda, vinegar, and boiling water method described earlier instead of harsh chemical drain cleaners.
• Repeat 2–3 times a week until drain flies disappear.

Prevention Tips: How to Keep Flies Away Long-Term

Once you’ve cleared an infestation, prevention keeps your home fly-free. Build these habits into your routine.

1. Keep the kitchen and dining areas clean

• Wash dishes or load the dishwasher right after meals.
• Wipe counters, stovetops, and tables daily.
• Sweep or vacuum crumbs from the floor regularly.
• Clean up spills (especially sugary drinks) immediately.

2. Manage trash and recycling properly

• Use bins with lids, both indoors and outdoors.
• Take out kitchen trash at least every other day; daily in hot weather.
• Rinse bottles and cans before placing them in the recycling bin.
• Clean the inside of trash cans monthly with hot soapy water or a disinfectant.

3. Protect entries: doors, windows, and vents

• Install or repair window and door screens; patch small holes immediately.
• Use door sweeps to close gaps at the bottom of exterior doors.
• Keep doors closed as much as possible; consider self-closing hinges or screen doors.
• Check vents for gaps and cover them with fine mesh if needed.

4. Control moisture and standing water

• Fix leaking pipes, faucets, and hoses.
• Don’t leave water sitting in buckets, trays, or plant saucers.
• Avoid overwatering indoor plants; let the top layer of soil dry between watering to prevent fungus gnats.

5. Maintain outdoor areas

• Pick up pet waste daily.
• Keep compost covered and follow proper composting practices.
• Move outdoor garbage bins away from doors and windows.
• Clean up leftover food and spills after barbecues or outdoor meals.

FAQ

How do I get rid of flies in my house fast?

For quick results, combine these steps in the same day:

• Remove or cover all food and take out trash.
• Set multiple traps (vinegar traps, sticky strips, or commercial fly traps).
• Kill visible flies with a swatter or vacuum.
• Identify and clean breeding sites: drains, garbage cans, pet areas, overripe fruit.

This approach usually cuts down fly numbers significantly within 24–48 hours.

What smell will keep flies away?

Flies dislike strong herbal and citrus scents. Commonly used repellents include:

• Lavender
• Peppermint
• Lemongrass
• Eucalyptus
• Citronella

Use them as diluted essential oil sprays around entry points and outdoor seating areas, not on food.

Why do I suddenly have so many flies in my house?

A sudden surge usually means:

• A new food or garbage source appeared (e.g., forgotten trash bag, dead rodent, or spoiled food).
• Flies are breeding somewhere indoors (drains, trash, overripe fruit, pet waste).
• Weather changes pushed outdoor flies inside through open doors and windows.

Inspect kitchens, trash areas, drains, and hidden corners for anything rotting or moist.

How long does it take to get rid of a fly infestation?

If you remove the breeding sources and use traps at the same time, you can usually control household flies in 2–7 days. Severe infestations, or those with hidden breeding sites (like dead animals in walls or attics), can take longer and may require professional pest control.

Are flies dangerous?

Flies can carry bacteria and contaminate food and surfaces, potentially causing illnesses like food poisoning. While a few flies are mostly a nuisance, a large number in food preparation areas is a hygiene risk and should be addressed quickly.

When should I call a professional exterminator?

Consider professional help if:

• You’ve tried cleaning, traps, and basic measures for more than a week with little improvement.
• You suspect a hidden breeding source (dead animal, inaccessible drains, structural issues).
• The infestation is large and spreading throughout multiple rooms or units.

By combining thorough cleaning, smart trapping, and consistent prevention, you can get rid of flies quickly and keep your home fly-free in the long term.
