How to Get Rid of Flies in Ashburn, VA: A Local Guide by Fly Type
If you are searching for how to get rid of flies, here is the short answer: find the breeding source, remove it, then trap the adults that are left. Killing flies one at a time never works, because a female house fly can lay several batches of around 100 eggs, and those eggs can hatch within a day.
This guide is written for homeowners and renters in Ashburn, Broadlands, Ashburn Farm, Brambleton and the rest of Loudoun County. You will learn how to identify the fly you have, which fix works for each type, and when it is time to call a local professional.
Quick Answer: 5 Steps to Get Rid of Flies Fast
- Identify the fly (house, fruit, drain, phorid, cluster or blow fly). Each has a different source.
- Remove food and moisture sources: overripe fruit, open trash, pet bowls, wet drains.
- Clean and sanitize trash cans, drains, compost bins and under appliances.
- Trap adults with vinegar traps, sticky traps or fly paper.
- Seal entry points and call a pro if flies are still around after about a week.
Why Are There Flies in My House? Common Causes in Northern Virginia
Flies are attracted to decaying organic matter and moisture. In Ashburn homes, the usual culprits are:
- Warm, humid summers that speed up fly breeding cycles.
- Garbage and recycling bins kept in garages or by patio doors.
- Pet waste and pet food in yards and on porches.
- Unused or slow drains in basements, utility sinks and guest bathrooms.
- Houseplants brought inside for the winter, which can carry fungus gnats and phorid flies.
- Fall weather, when cluster flies look for sheltered spots to overwinter in walls and attics.
- Hidden problems such as a dead rodent in a wall void or attic.
Identify the Type of Fly in Your Home
Correct identification is the step most online guides skip. Spraying a house fly remedy at drain flies will not help.
| Fly type | What it looks like | Where it breeds | Best fix |
|---|---|---|---|
| House fly | Gray, medium size, buzzes loudly | Trash, pet waste, rotting food | Sanitation, sealing, traps |
| Fruit fly | Tiny, tan with red eyes | Ripe fruit, spills, recycling | Remove produce, vinegar trap |
| Drain fly | Small, fuzzy, moth-like wings | Gunk inside drains | Scrub drain, enzyme cleaner |
| Phorid fly | Small, dark, runs in jerky bursts | Damp decay, soil, leaky pipes | Find the moisture source |
| Cluster fly | Larger, slow, golden hairs | Outdoors (soil); overwinters in walls | Exterior sealing, vacuum |
| Blow fly | Shiny blue or green | Dead animals, meat | Locate and remove the source |
How to Get Rid of House Flies
House flies are the classic summer problem. They enter through open doors, torn screens and small gaps, then lay eggs in anything damp and rotting.
Step 1: Seal their pathways
Repair window and door screens, add door sweeps and caulk gaps around pipes and utility lines. If gaps are big enough for flies, they may also be big enough for mice, so see our rodent exclusion service in Ashburn for a full exterior seal.
Step 2: Fix your trash routine
Use lidded bins, take trash out often, rinse bins monthly and keep them away from doors. Pick up pet waste from the yard promptly.
Step 3: Use traps
Hang fly paper or place sticky traps near windows and where flies gather. UV light traps can help in garages and kitchens when placed away from where you prepare food.
Step 4: Try the dark-room window trick
Flies head for light. On a sunny day, close off the room, shut the blinds, leave one bright gap, and let the flies gather there so you can trap or vacuum them.
How to Get Rid of Fruit Flies
- Refrigerate ripe produce or keep it covered, and take out recycling that contains juice or beer residue.
- Make a trap: pour apple cider vinegar into a jar, add a drop of dish soap, and cover with plastic wrap with a few small holes.
- Wipe counters, sink edges and the area around the trash daily for a week.
How to Get Rid of Drain Flies (Moth Flies)
Drain flies live in the slimy film inside pipes. Spraying the air will not stop them.
- Tape a piece of clear tape over the drain overnight. If tiny flies stick to it, the drain is the source.
- Scrub the pipe walls with a stiff drain brush.
- Use an enzymatic drain cleaner to break down the organic film. Do not pour pesticides down the drain.
- Run water through unused drains weekly, especially basement floor drains and guest bathrooms.
If you also see roaches near drains or under sinks, read about our cockroach control service, since both pests love moisture and food residue.
How to Get Rid of Cluster Flies in Fall and Winter
Cluster flies are different. They develop outdoors and then move into wall voids and attics in autumn. On warm winter days they wake up and crowd windows. Because they are breeding outside, interior sprays and sanitation will not fix them.
- Vacuum them up and dispose of the bag outdoors.
- Seal gaps around windows, siding, soffits and utility entries with exterior-grade caulk before next fall.
- Book a professional exterior treatment in early fall if you have had repeat problems.
Big Flies Indoors With No Obvious Source? Check for a Dead Animal
A sudden swarm of shiny blue or green flies can mean a dead mouse, rat or squirrel inside a wall, attic or crawlspace. Treating the flies will not solve it. The animal has to be found and removed. If you also hear scratching or notice droppings, start with our mice and rat control page.
Are Those Flies, or Something Else?
Not every small flying insect is a fly:
- Large, thin-waisted insects with a stinger are wasps or hornets. See wasp and hornet control in Ashburn.
- Biting insects near water or at dusk are likely mosquitoes. See mosquito control in Ashburn.
- Pets scratching along with tiny jumping insects points to fleas. See flea control.
Cobwebs near windows are often a sign spiders are feeding on flies. That is useful, but it also tells you flies are getting in. If webs become a problem, see our spider control service.
Do Natural Fly Repellents Work?
Essential oils, herbs and citrus sprays are popular online. Some may briefly discourage flies, but none removes a breeding source. Treat them as a small extra, not the main plan. Sanitation, sealing and traps do the heavy lifting.
How to Keep Flies Out of Your Ashburn Home for Good
- Keep screens in good repair and doors closed when not in use.
- Store trash in sealed bins and clean them regularly.
- Wipe spills right away and do not leave food or pet bowls out overnight.
- Clean drains monthly and fix leaking pipes.
- Keep compost away from the house and covered.
- Schedule an exterior inspection each fall before cluster flies move in.
When to Call a Pest Control Professional in Ashburn
DIY works for most small fly problems. Call a pro if:
- Flies keep coming back after a week of cleaning and trapping.
- You see many large flies and cannot find the source.
- You suspect a dead animal or hidden moisture problem.
- Cluster flies return every fall.
- You run a restaurant, daycare or other business where flies are a health-code concern.
A licensed technician identifies the exact species, finds the hidden source and applies a targeted treatment, so you are not guessing.

Frequently Asked Questions About Getting Rid of Flies
What is the fastest way to get rid of flies in my house?
Remove what attracts them, then use a vinegar trap or sticky traps for the adults. Real speed comes from removing the breeding source, not just the flies you can see.
Why do I suddenly have so many flies in my house?
A sudden surge usually means a breeding source nearby: overripe produce, a dirty drain, a full trash can, pet waste, or a dead animal in a wall or attic.
Are flies in the house dangerous?
House flies can carry bacteria such as Salmonella and E. coli, so keep food covered and surfaces clean.
Why are there flies in my house in fall and winter?
Most likely cluster flies, which overwinter in wall voids and attics and appear sluggish on sunny windows.
When should I call a pest control company for flies?
If flies persist after about a week of sanitation and trapping, if you see many large flies with no obvious source, or if you suspect a dead animal.
