What Are Drain Flies? Understanding Your Enemy
Before you can effectively eliminate drain flies, you need to understand what you’re dealing with. These small, moth-like insects (Psychodidae family) have distinctive fuzzy bodies and wings that make them easily recognizable.
Appearance
Drain flies are tiny (2-5mm), with a moth-like appearance featuring fuzzy, light gray or tan wings held roof-like over their bodies. Their bodies and wings are covered with fine hairs, giving them a “fuzzy” look.
Habitat
These pests thrive in moist environments with decaying organic matter. Common breeding sites include drains, sewage systems, compost piles, and areas with standing water like air conditioner units.
Life Cycle
The life cycle consists of four stages: egg, larva, pupa, and adult. A female can lay up to 300 eggs, which hatch into larvae within 48 hours. The complete cycle from egg to adult takes about 7-21 days depending on conditions.
Why Drain Flies Are Dangerous
While drain flies don’t bite or sting, they can pose significant health risks, particularly in large numbers. These insects develop in and feed on the decaying organic matter in drains, sewage systems, and similar environments that harbor numerous harmful pathogens.
Drain flies can carry and spread various bacteria including salmonella, E. coli, and other pathogens associated with sewage. These microorganisms can potentially cause infections and diseases such as:
- Gastroenteritis and food poisoning
- Bacterial eye infections
- Respiratory issues (especially for those with compromised immune systems)
- Allergic reactions in sensitive individuals
Additionally, drain fly infestations can indicate underlying plumbing issues such as leaks or severe drain clogs that need to be addressed.
How to Identify a Drain Fly Infestation
Wondering if you have drain flies? Here’s how to confirm their presence:
- Visual Identification: Drain flies are most active at night and are attracted to light. Look for small, moth-like insects resting on bathroom or kitchen walls, especially near drains.
- The Tape Test: Place a piece of clear tape over the drain overnight (sticky side down). In the morning, check for trapped flies, confirming the drain as a source.
- Inspect for Larvae: Using a flashlight, examine the inside of drains and pipes for a gelatinous, slimy substance that may contain small, worm-like larvae.
- Check Moist Areas: Beyond drains, examine areas with standing water or moisture such as rarely used toilets, shower drains, condensate pans under refrigerators, and AC units.
How to Get Rid of Drain Flies: Comprehensive Solutions
Successfully eliminating drain flies requires a multi-faceted approach targeting both adult flies and their breeding sources. Here’s your action plan for complete eradication:
Step 1: Clean and Disinfect All Drains
The most effective way to eliminate drain flies is to remove their breeding sites. Start with a thorough cleaning of all drains in your home:
Manual Cleaning
Enzymatic Treatment
Boiling Water
- Use a Drain BrushStart by physically removing as much buildup as possible from inside drains. Use a pipe brush to scrub the inside walls of drains, removing the biofilm where larvae develop.
- Apply Enzymatic CleanersBio-enzymatic drain cleaners break down organic matter that drain flies feed on. Pour the recommended amount down all drains and let sit overnight before rinsing.
- Boiling Water TreatmentPour boiling water down drains daily for at least a week. The hot water helps kill larvae and eggs while washing away breeding material.
- Baking Soda & VinegarPour ½ cup baking soda down the drain, followed by 1 cup of white vinegar. The foaming action helps loosen drain buildup. After 1 hour, flush with hot water.
- Clean ALL drains in the affected area, even those that seem unaffected
- Don’t forget overflow drains in sinks and tubs
- Remove and clean P-traps under sinks if accessible
- Focus on drains that are used less frequently as they often develop more buildup
Bio-Enzymatic Drain Gel
InVade Bio Drain Gel
Editor's ChoiceHow Does It Work
How to Use
- For standard drains: Apply 4-8 oz around the edges of the drain
- For floor drains: Pour 8-16 oz directly into the drain
- Apply at night when drains won't be used for several hours
- Repeat application 2-3 times weekly until flies are eliminated
- For maintenance, apply once weekly to prevent recurrence
- Professional-strength formula used by pest control companies
- Safe for all pipes and septic systems
- No harsh chemicals or fumes
- Continues working for days after application
- Eliminates the source of the problem, not just adult flies
- More expensive than some DIY solutions
- May require multiple applications for severe infestations
- Slight citrus odor (though most find it pleasant)
Step 2: Eliminate Adult Drain Flies
While cleaning drains tackles the source of the problem, you’ll also need to address adult flies already in your home:
- Fly Traps: Place sticky fly traps near affected drains to catch adult flies. Look for traps specifically designed for small flies.
- Apple Cider Vinegar Trap: Fill a small bowl with apple cider vinegar, add a few drops of dish soap, and cover with plastic wrap with small holes poked in it. The vinegar attracts flies, and the soap breaks surface tension so they drown.
- Essential Oil Spray: Mix 10-15 drops of essential oils (like eucalyptus, lavender, or tea tree) with water in a spray bottle and spray around drains and affected areas. While this won’t kill flies, it can help repel them.
Drain Fly Strip Treatment
Green Gobbler Drain Fly Killer
People's ChoiceHow Does It Work
How to Use
- Remove the protective film from one drain strip
- Place the strip directly over the drain opening (especially effective for flat drains)
- Follow with an application of the gel formula down the drain
- Replace strips every 30-60 days or as needed
- For severe infestations, use both strips and gel in all household drains
- Easy to use strip format requires no measuring
- Pleasant citrus scent masks drain odors
- Safe for all types of plumbing including septic systems
- No harsh chemicals or caustic ingredients
- Made in the USA
- Strips may not fit all drain configurations
- May require multiple applications for established infestations
- Some users report strips can dissolve quickly in very wet conditions
Step 3: Fix Plumbing Issues
Addressing underlying plumbing problems is crucial for permanent drain fly control:
- Repair Leaking PipesEven small leaks create the moist environment drain flies need to thrive. Check under sinks, around toilet bases, and behind washing machines for leaks.
- Clear Clogged DrainsSlow-draining pipes allow organic matter to accumulate. Use a plunger, drain snake, or call a plumber to clear stubborn clogs.
- Fix Condensation IssuesAddress condensation on pipes that creates constant moisture. Insulate cold water pipes in humid areas to prevent condensation.
- Seal Cracks Around PipesUse silicone caulk to seal gaps around pipes where they enter walls or floors, eliminating hidden breeding spots.
Preventing Drain Flies: Long-Term Solutions
Once you’ve eliminated a drain fly infestation, use these prevention strategies to keep them from returning:
Regular Drain Maintenance
Flush all drains weekly with hot water followed by ½ cup of white vinegar. For rarely used drains (like guest bathrooms), run water through them weekly to prevent the trap from drying out.
Eliminate Standing Water
Don’t leave water standing in sinks or showers. Fix leaks promptly and ensure good drainage in potted plants, air conditioner drip pans, and garbage cans.
Keep It Clean
Clean garbage disposals regularly with citrus peels and ice cubes. Remove hair from shower drains with a drain protector, and regularly clean pet water bowls.
When to Call Professional Pest Control
While most drain fly problems can be resolved with DIY methods, some situations warrant professional intervention:
| Consider Professional Help If: | What Professionals Can Do: |
|---|---|
| Persistent infestation despite multiple DIY treatments | Apply commercial-grade products and identify hidden breeding sources |
| Widespread infestation throughout multiple areas of your home | Conduct whole-house inspection and treatment plan |
| Suspected sewer line breaches or major plumbing issues | Coordinate with plumbers to address structural issues |
| Health concerns due to large numbers of flies | Provide rapid elimination using integrated pest management |
What to Expect from Professional Pest Control
When you hire professional pest control for drain flies, here’s what typically happens:
- Inspection: They’ll identify all breeding sites, including those that might be hidden or difficult to access.
- Treatment: Pros will use specialized equipment to thoroughly clean drains and apply professional-grade products that target all life stages.
- Recommendations: You’ll receive specific advice about plumbing repairs or modifications needed to prevent future infestations.

- When using any chemical products, always wear gloves and ensure proper ventilation
- Keep children and pets away from treated areas until products have dried
- Never mix cleaning products, especially bleach and ammonia, as this can create toxic fumes
- Follow all manufacturer instructions for application and safety precautions
Frequently Asked Questions About Drain Flies
Can drain flies come up through the toilet?
Yes, drain flies can emerge from toilets, especially rarely used ones. The water in the P-trap can evaporate, allowing flies to access the drain. They may also come from cracked or damaged seals around the toilet base.
To prevent this, flush unused toilets weekly, check for leaks around the base, and consider adding a tablespoon of mineral oil to the toilet bowl water in rarely used bathrooms to prevent evaporation.
How quickly can drain flies infest a house?
Drain flies reproduce rapidly under ideal conditions. A single female can lay up to 300 eggs, which hatch within 48 hours. The entire life cycle from egg to adult takes only 1-3 weeks depending on temperature and food availability.
This means that what starts as a few flies can become a full infestation within a month if the conditions are favorable. This is why quick action is essential once you notice the first few drain flies.
Will drain flies go away on their own?
Drain flies will typically not disappear on their own as long as their breeding sites remain undisturbed. Without intervention, the organic matter in drains will continue to support the development of new generations of flies.
Even if some adult flies die naturally (they live about 2 weeks), new ones will continually emerge from eggs laid in drains. Only by eliminating breeding sites can you permanently resolve the infestation.
Are drain flies and fruit flies the same?
No, drain flies and fruit flies are different insects with distinct characteristics:
- Drain flies are small, moth-like insects with fuzzy wings and bodies that breed in drains and sewage
- Fruit flies are typically light brown with red eyes and are attracted to ripening fruits and vegetables
While both can be household pests, they require different treatment approaches targeting their specific breeding sites and habits.
Conclusion: Winning the Battle Against Drain Flies
Eliminating drain flies requires persistence and a comprehensive approach that targets both the adult flies and their breeding sites. By following the strategies outlined in this guide, you can effectively rid your home of these pests and prevent future infestations.
Remember that the key to success lies in removing the organic matter that drain flies need to reproduce. Regular drain maintenance, fixing plumbing issues promptly, and eliminating standing water will create an environment where drain flies cannot thrive.
For stubborn infestations, don’t hesitate to combine multiple approaches or seek professional help. With consistent effort and the right techniques, your home can be drain fly-free for good.
very helpful comments i used 2 gallons Clorax dwn sewer clean out caps put new caps sprayed all drains after 2 days ev thing gone original problem started after plumber clean backup BUT did not put caps in trap on tightly also sprayed outside breather pipe thanks for all your comments!!
I have 5 to 10 flies an hour coming into my bathroom and they settle on the window. I kill them and more show up again. I have tried to see where they come in but so far I have not been able to determine that. At first I thought they were coming in at cracks at the window but I am not sure now. If I have drain flies here are a few questions.
1. How do the drain flies come through the liquid in the p trap?
2. Can you test to see if you have drain flies by capping all the drains in the bathroom and seeing if they still show up?
3. How can you determine if the flies are drain or gnats or regular flies since I cannot examine the flies closeup since they have already been killed.
Drain flies are easy to see. The dead flies look just like the pictures you can find on the internet. If killed they become dust-like. From what I’ve read, they lay their eggs in the gunk in the drain or on rotting wood from a leaking drain. Also, I have researched products high and low trying to find something to rid my house of the pesky critters. For months I have poured baking soda, salt & vinegar down the drains overnight & closed the stopper, only to wake you find flies on the bathroom walls. I tried putting tape over the sink opening. Not once have I trapped one coming up from the drain. I thought my problem might stem from the air conditioning vents sooooo, I put cheese cloth behind the vents to no avail. It wasn’t until I read a comment on this site about WD40 did I think that my problem could possible be from the flies coming up from around the seal of the toilet. I sprayed about 4 hours ago and haven’t seen a drain fly, yet. Hoping and praying this helps! If not, I’m calling a plumber.
Mare, what did you spray around the toilet?
Main drain in our street became blocked and sewage was filling up under the floorboard of 4 houses. contacted Scottish water who sent someone out to drain from under our houses. Now infested with drain flies. AAAARRRGH there are thousands of the little buggers. Had a guy out yesterday and sprayed something under the floorboards. It is all contained to the ground floor of the house. I want to move out but hubby says we stay they go.
Before all the chemicals, try to pour couple cups of vinegar down all the drains. Also use a spray bottle fill with IPA and spray down the moth flies you see on your bathroom walls (kills on contact).
I have tried Clorox / Purex but have been concern especially with ammonia mixing flush many times the baking soda vinegar mixtures soap powders and liquids boiling hot water seen spiders and abundants of all kinds bugs. Scrub routinely ,covered drains or uncover drains makes sometimes little difference with odor. ALWAYS cleaning w solutions after fecal or urine usage in toilet. Live in apartment there is a routine spraying program which has seem to make it worse @ times more flying type insects and coming from Vents with all kinds things coming out of them plus washing room drain has had sewer gas odor that is next to ice cube connector for refrig .

Third month combat those small tiny flies Rai, dishsoap and vingar trap- flying up from sink. Now they are in livingroom hallway wall. Landlird professional riach spray never elimated this getting worse.
What should I do?
I have drain flies in the toilet, shower, and even in my dog’s water dish that is inside. Does this mean that they are in the water system that we drink and bath in, and if so is it safe to continue using it until we get rid of them?
So, I repeated the baking soda and vinegar treatment. And this time I also removed the air vent chrome thing at the back of the sink top, and cleaned it with baking soda and vinegar. I sprinkled baking soda where it comes up from under the sink, (the opening where I removed the chrome top) and poured a small amount of vinegar on top. (this could be a really bad idea generally, I don’t know). Three days now, and no more flies. Maybe I won’t need to use anything else.
I’m also using Gentrol (hydropene). We’ve never had these before, and I hope to get rid of them for a very long time.
Thank you for all the suggestions. I am testing imidacloprid, which is sold under various names, to see if it will get rid of these pests. I will let you know if it works. Good luck to all of us!
Sewer Flies bothered me for several seasons, ,unfortunatly they can mutate and cause real problems and expense.The cheapest thing to do is throw away all the baking soda salt and vinegar to the side and buy a can of flying insect kill spray your drain after evening use and see how fast the problem goes away.
I have found an easy way to kill any type of insect from ants to flies to roaches – Anything.
WD-40. WD-40 works by displacing water. Basically it sticks and spreads faster and better than water.
I know it sounds crazy until you understand how small insects breathe.They don’t have lungs, they “breathe” by passive oxygen/CO2 exchange thru small holes on their legs & abdomen. If they get something like WD-40 on them they automatically try & clean it off & spread it around & onto these holes & it blocks oxygen exchange & they suffocate. If the insects are in your drains, cram a dry cloth towel down & then pull it back up & repeat until it is mostly dry. Use a white one that you can bleach. Then spray down LOTS of WD-40. Leave it alone (no water) for a couple of days. No worrying about toxic chemicals. Works like a charm.
I just got introduced to these drain flies a month ago when I saw them on the walls of my apartment but with me the most of them were by the sliding doors in my living room and my bedroom. They are such nasty things and when you kill them they leave a black smudge. I live in a city and didn’t think there were these types of bugs here. The pest control people came in and sprayed the cupboards under my sink, I am not sure why that would help? and all I can smell is what they sprayed and I can’t open my windows to air out the smell. He said that I needed to keep all my windows and doors shut so I assume they thought that they were getting in that way.
This is my third year fighting drain flies. I have tried in-vade bio drain. did not help. since I have tried a combination of salt, baking soda and white vinegar I have almost won the battle.Now I only see one or two at a time. prior to this treatment there were many more. In as much as I have not won the war, I feel I am winning the battle. can not find the source, however. I will continue to use this treatment and now add mineral oil to the drains. good luck let me know how you all make out
Ecosmart Organic Home Pest Control will actually kill the larvae.
It is made of 2-Phenethyl Propionate, which is the only ingredient on the label that sounds like it is a chemical to read up on. The rest of the ingredients are essential oils which are OK but the smell will get to you eventually. From what I read you might have to treat the area for up to 3 weeks and from my experience that is the case. You have to keep applying this in places where the larvae grow like in the gaps of your tile grout. I tried everything and the tiny larvae seem to be immune to chemicals. I had one in a bucket and it was submersed in Mr. Clean for 3 days and it was still active and moving as much as the first day. I tried bleach, ammonia and other safer products but they did not work. They get the larvae to come out but they do not die and eventually go back and continue growing. Only Ecosmart actually drove them out of the crevices and they died.
The flies eventually stop coming and then the larvae all die out. If you see a fly after 1-2 weeks of treatment, you are missing something. Find where they are emerging from.
Good Luck
First of all, you probably know this already but never, ever allow bleach and ammonia to mix together!! It will create VERY toxic fumes that will destroy the lungs, and people have died from this.
I had found these horrid little worm-like larvae in my bathroom sink and in my kitchen sink. I wasn’t even aware of the ones in my kitchen until one was somehow transferred from the sink into my cats’ water bowl! Yuck! I was so upset by this.
Well, they seem to be impervious to nearly everything chemical. (I DO like Dave’s advice, below, re: WD40.) Anyway, one “worm” was in a lid in my kitchen sink. I poured blue Dawn on it (the formaldehyde in Dawn will kill a flea instantly,) I poured Lysol into the lid, and I also covered the creature with salt!! Made no difference.
They cannot survive mechanical action: being squished – but who wants to do that? I then thought of something else they probably couldn’t survive: boiling water. It killed the one that was in the lid. I then poured some boiling water down every drain in my house, and continue to do this every few days. Have seen no more evidence of them.
I have drain flies on the outside of my house , they just get all over the walls and doors and when you open the door they fly into the house. They get very annoying inside as they become quite lively at night and dive bomb into your face. We do have a septic tank in the front yard and also a large city storm drain. Please advise, I would appreciate your help. My exterminator sprayed the outside walls, but this didn’t seem to help much. Thank you
We are infested with drain flies and also have a septic system. Even spent 600 dollars to replace A laundry room drain..think their in the walls of a room on a slab.. Going in and out of my windows. Camera on our septic line shows cracks but everyone says there not bad… We have had plumbers contractors and insect control but no solutions. Can they be in the soil under our home?
The septic tank was cleaned and the lid not properly put back on – we found after calling because the outside of our home, which is near the lid is covered with drain files. The guy fixed the lid, but as soon as he opened it all you saw was drain flies. Everything tells how to get rid of them in the drains and in your house – -what do I put in my septic tank to stop them from breeding. If you go out and kick the lid – out they come. HELP
I see one of these flies once in a blue moon in a bathroom. Is that a “problem” or just a random fly that got in? We do have a septic tank right outside the bathroom where they are seen and I do use a product to biodegrade the contents of the septic tank. Now, growing up we had tons of these flies in our basement which happens to be where my room was. Should I be concerned? I also have been diagnosed with fibromyalgia not long after I moved out of my childhood home. Thanks for any advice or help.
To kill,at least bring them down, the flies i simply spray them with soap water with spayer.but they root of the problem is the larvae coz they seems brreeding faster than the ones i kill,i need to work it out
I have some sort of tiny fleas crawling up one wall and lodge into the extreme corner of the same wall in my bathroom. Though I used all kinds of pest control, like Heat spray, kerosene, etc. these insects repeat their process up the same wall. At times I have found same insects under the plastic bucket and mug when dry. As suggested above, can I now use Baygon spray or liquid put into the drains of bathroom, sink, toilet. Please confirm or advise alternative treatment. Thnks.
I am a painter and while on an estimate I noticed sewer flies. The owner stated that they have treated the drains but it takes some time for the problem to be taken care of. I am concerned that if I take this job I can bring them home with me. Is this a valid concern?
If u have the flys in bath room u most likely have a leak somewhere. If u do not see the leak then it most likely is underground
I have a fly infestation in my bathroom and they are mostly in the shower cubicle. After many attempts of using drain cleaner they are still present. I cannot get to the drain as it is under a tiled bathroom floor so have just used gels and foam cleaner. I would be gratfull if you have any sugestions on how to clear them.
they nest in the YUK junk inside the drains like hair buildup and others items that are stuck in your drains. You need to get that junk OUT (not snake it down further) -then using a pipe brush clean as far as the brush will reach. Then, once the drain has been cleared of all debris possible-then you pour the GEL drano type of product. Im unsure how you are able to use the gels and foams you mention if you can not access your drain cover, another quick fix to clean out the drain pipes adequately would be to use a vinegar baking soda mixture poured down the drain.
I know in my experience if they were in the shower cubicle then they are in the bathroom sink as well. I found most of them and their larvae etc in the top hole thing in my sink(think its to prevent sink from flowing over if filled to high?) Bleach didn’t kill the larvae, they managed to crawl up out of the sink and onto the counter after I WAS SURE THEY WERE DEAD-unpleasant to say the least. Again drain pipes must be clean to get rid of them as they breed in the organic matter that lives in and on the sides of the pipes. You may want to try a type of enzyme killing organic type gel available at most hardware stores. Without drain access that may be your best option at cleaning out most of the organic yuk rotting in the drain.
I have had problems with those tiny little black speck bugs in my bathrooms and kitchens in both Phoenix and Flagstaff for months. I tried everything. Professional fumigations, bug spray, bleach. Nothing worked.
FINALLY, my husband brought home from work some of the bottled alcohol stuff for rubbing on hands to keep off germs on your hands! Voila! I took that and generously rubbed it all over my sinks, countertops, and even in the little hole in the bathroom sink to let excess water escape. DO NOT WASH OFF. JUST LET IT STAY THERE!
No more bugs!
They are GONE! I do it every day. Just smear the alcohol-based hand wash around and it either kills the larvae and/or the bugs but what a relief!
Good Luck!
Did you have larvae and flies on your kitchen ceiling? That’s what IM DEALING WITH and can’t figure out what they are and how they got here. Have gone through all food so that’s not it. Checking the sink next.
Do you mean the real alcohol or the hand sanatizer?
Very helpful information. Thank you Do you mean the real alcohol or hand sanitizer?
have drain mites. how can I get rid of them permanently?
Killed them once b ut they were back in 2 weeks.
Where can I buy the correct chemicals?
I have the same problem. they were gone for 1 wk then returned. using vinegar jars but not eliminating . NEED HELP !
Are u talking about hand sanitizer
I tried it and it worked the first day. I even put the hand sanitizer down the drain. I’m going to treat my bathroom sink for a couple of weeks, and hope I’m rid of them permanently. Thank- you so much!!!
what are the products for destroying drain flies? Where and how can I buy locally or by mail?
Thanks
what are chemicals to kill sewer flies in tolet bowl pipes? Where can I buy them?
What product is used to kill sewer mites in the bathroom??
I have to share this because I have had drain flies for the past two years that I bought and lived in my nEw home. I feel like I have tried everything: Vinegar and baking soda, bleach, pest control companies have poured “who knows what” chemicals down my drain and finally three months ago I paid a plumbing company to clean out my drains. But the flies were still there for weeks and months after. The plumbing guy suggested I cover the drain with a cloth and pour bleach slowly over the cloth and leave it there to allow the bleach to seep down the drain slowly. For the last three month I have had a cloth covering the drain and poured bleach on the rag twice, filled the area with water (so that the bleach could seep through the rag slowly). The flies are finally gone!!! Gone!!!! I am not sure if cleaning out the drains helped but I definitely believe that having the rag cover the drain for months with the occasional bleach and water being poured on top has done the trick. And I had to share so anyone who reads this so they can benefit from my experience. Finally!! Those bugs just wouldn’t go away with anything I have tried until now. Finally free!
Ty I have drain fly’s and they are annoying i can’t stand it i will try this!
Do you use the bleach straight or do you dilute it? thank you for this advice.
I worked in restaurant facilities and at first sight of drain flies we were told to pour bleach in the drains and to do it periodically thereafter to keep them from coming back.
COMET WITH BLEACH-CAN FORM- WET THE DRAINS BRIEFLY, THEN SPRINKLE HEAVILY ON ,THROUGH AND AROUND, ALL DRAINS AND COMMODE. LEAVE IT THERE INDEFINITELY, RESPRINKLE AFTER USE.
THIS TAKES CARE OF MY WALKOUT BASEMENT BATH.( THIS BASEMENT IS THE ENTRANCE TO MY HOME.)
Spray DW40 on the sides of the drain and into its bottom directly. Within 2 days your problems will be over with drain flies.
Omg!! This stopped them in their tracks! It instantly killed the ones on windows! I even went outside and sprayed a ton of it all over spot where I had sump pump drainage problem and the soil is still really water logged. Not sure how well that will work but can’t hurt to try til I get to store for something stronger. Plan on digging that area this fall when it dries out and putting cement down for next year. A million times thank u for posting this. I feel like I have been in a war zone at home for 2 weeks and hated using raid all time as bad to breathe. House smells like Wd40 right now but I will take that over the flies. Hopefully it will help longer than raid.
Another thing I forgot is I used generic Wd40 so very cheap help.
After doing the soda, vinegar hot water there were no change except the mouldy smell seem to have finally gone. Even tried out the tape over the sink but saw nothing but these wretched flies continued to appear. Decided to try the wd40 after reading you comment and can say that the wd40 worked for me. Sprayed in crevices along skirting panels where there are gaps around sink areas and floor then followed by fly spray in the air around the room close doors and windows, follow instructions on fly spray can, day 2 saw 1 in the morning, waiting for evening when the lights go on as they tend to appear in the evenings mostly. Repeated the spray and wd40 again though and the soda vinegar hot water down the toilet for the first time as 2 appeared in the toilet. Eventually they will have no place to hide. Wd40
Pour pine oil or pineSol down your drain
