Figuring out how to get rid of flies in your house fast becomes urgent when they start buzzing around your kitchen. Flies aren’t just annoyingโthey carry bacteria and contaminate food. A few flies can turn into dozens within days if you don’t act quickly.
The good news is that most fly problems can be solved with simple household items and basic prevention. This guide covers the fastest ways to eliminate flies and keep them from coming back.
Why Flies Invade Your Home
Understanding what attracts flies helps you eliminate them faster.
Common fly attractants:
- Rotting food and organic matter
- Garbage and compost bins
- Pet waste and litter boxes
- Dirty drains with buildup
- Overripe fruit on counters
- Spilled liquids and food residue
- Dead animals in walls or crawl spaces
Flies enter through open doors, torn screens, and gaps around windows. Once inside, they multiply rapidlyโa single female can lay up to 500 eggs in her lifetime.
10 Fast Methods to Get Rid of Flies
1. Make a DIY Fly Trap
Homemade traps work surprisingly well and cost almost nothing.
Apple cider vinegar trap:
- Pour apple cider vinegar into a jar or bowl
- Add a few drops of dish soap (breaks surface tension)
- Cover with plastic wrap
- Poke small holes in the wrap
- Place near fly activity
Flies are attracted to the fermented smell, enter through the holes, and can’t escape. Replace every few days.
Wine or beer trap:
Leave a nearly empty bottle of wine or beer out. Flies crawl in but can’t find their way out.
2. Use a Commercial Fly Trap
Store-bought options work faster for heavy infestations.
Effective commercial traps:
- Sticky fly ribbons (hang near problem areas)
- Window fly traps (stick to glass)
- Electric fly zappers (for garages and outdoor areas)
- Baited fly traps (for fruit flies)
Place traps where you see the most activity, usually near windows, trash cans, and food prep areas.
3. Try Essential Oil Repellents
Certain scents drive flies away naturally.
Oils that repel flies:
- Peppermint
- Eucalyptus
- Lavender
- Lemongrass
- Citronella
How to use:
- Add 10-15 drops to a spray bottle with water
- Spray around doorways and windows
- Soak cotton balls and place near entry points
- Use in a diffuser
Essential oils repel flies but won’t kill existing ones. Use alongside traps for best results.
4. Clean Drains Thoroughly
Drain flies breed in the organic buildup inside pipes. Regular cleaning eliminates their breeding ground.
Drain cleaning method:
- Pour boiling water down the drain
- Follow with half cup baking soda
- Add half cup white vinegar
- Wait 15 minutes
- Flush with more boiling water
Repeat weekly for drains with recurring fly problems. A drain brush helps remove stubborn buildup.
5. Eliminate Food Sources Immediately
Remove what attracts flies and they’ll leave.
Quick actions:
- Throw away overripe fruit or store in the refrigerator
- Take out garbage daily, especially food waste
- Clean up pet food bowls after feeding
- Wipe down counters after meal prep
- Rinse recyclables before storing
- Clean spills immediately
Even small crumbs attract flies. A quick kitchen wipe-down makes a big difference.
6. Use Fans to Disrupt Flight
Flies are weak fliers. Air movement makes it hard for them to land.
Fan placement tips:
- Point oscillating fans toward food prep areas
- Use ceiling fans during meals
- Position a fan near entry doors
- Keep air moving in problem rooms
This won’t eliminate flies but keeps them away from specific areas while other methods work.
7. Make a Dish Soap Spray
A simple spray kills flies on contact.
DIY fly spray recipe:
- 2 cups warm water
- 1 tablespoon dish soap
- 1 tablespoon white vinegar
Spray directly on flies. The soap coats their wings and suffocates them. This works best for flies resting on surfaces.
8. Hang Herbs Near Entry Points
Fresh or dried herbs repel flies naturally.
Effective herbs:
- Basil (especially effective)
- Mint
- Bay leaves
- Lavender
- Rosemary
Place potted basil near kitchen windows. Hang dried herb bundles near doors. Crush leaves occasionally to release more scent.
9. Use Light Traps at Night
Flies are attracted to light. Use this behavior against them.
Light trap method:
- Turn off all lights except one lamp
- Place a trap near the light source
- Flies congregate around the light and get trapped
UV light traps work even better. They attract flies and either zap them or trap them on sticky surfaces.
10. Seal Entry Points
Stop new flies from entering while you deal with existing ones.
Entry points to check:
- Window screens for tears
- Door sweeps and weatherstripping
- Gaps around window AC units
- Cracks around door frames
- Openings around pipes and vents
Repair screens immediately. A single small tear lets in dozens of flies.
Identify the Type of Fly
Different flies need different approaches.
House flies: Large, gray, attracted to garbage and food waste. Use traps and eliminate food sources.
Fruit flies: Tiny, tan, swarm around ripe fruit and drains. Apple cider vinegar traps work best.
Drain flies: Small, fuzzy wings, found near sinks and showers. Clean drains to eliminate breeding sites.
Cluster flies: Large, slow-moving, appear in fall seeking warmth. Seal entry points and vacuum them up.
Blow flies: Metallic green or blue, indicate dead animals nearby. Find and remove the source.
Identifying the fly type helps you target your efforts effectively.
When Flies Indicate a Bigger Problem
Sometimes flies signal issues beyond simple sanitation.
Warning signs:
- Sudden large numbers of blow flies (dead animal in walls)
- Flies appearing in winter (breeding site inside)
- Persistent drain flies despite cleaning (broken pipes)
- Flies concentrated in one area (hidden food source)
If you find excessive blow flies, check for dead animals in attics, crawl spaces, or wall voids. A Riverside pest control company can locate and remove dead animals you can’t find or access.
Prevent Flies From Returning
After eliminating current flies, prevention keeps them away.
Daily habits:
- Take out garbage containing food waste
- Wipe down kitchen surfaces
- Clean pet areas
- Store fruit in the refrigerator
- Rinse dishes before leaving in sink
Weekly maintenance:
- Clean garbage cans with soap and water
- Flush drains with boiling water
- Check screens for damage
- Empty and clean compost bins
Seasonal tasks:
- Install or repair window screens in spring
- Check weatherstripping before summer
- Seal any new cracks or gaps
- Clean outdoor trash areas
Natural vs Chemical Fly Control
Both approaches have their place.
Natural methods work best for:
- Minor fly problems
- Homes with children and pets
- Ongoing prevention
- Kitchen and food areas
Chemical methods may be needed for:
- Heavy infestations
- Outdoor areas
- Garages and workshops
- When natural methods fail
If using chemical sprays, follow label directions carefully. Don’t spray near food or food prep surfaces. Ventilate treated areas well.
Get Rid of Flies in Your House Fast
Learning how to get rid of flies in your house fast comes down to three things: eliminate what attracts them, trap and kill existing flies, and prevent new ones from entering.
Start with the fastest methodsโtraps and removing food sources. Most fly problems clear up within a few days once you cut off their food and breeding sites.
For persistent problems or sudden heavy infestations, don’t hesitate to call a professional. Some fly issues indicate hidden problems that need expert attention.
Keep up with prevention after the flies are gone, and you won’t have to deal with another infestation.
