Pesticide Treatments These products will not kill the larvae and new flies will soon appear. "Bug bombs" (i.e., total-release aerosols) will only kill flying adults and they leave no residues. These products should not be used around food preparation areas.
Apple cider vinegar with a drop of dish soap: leave in a shallow plate or bowl (I used a tiny fish bowl from thrift store) near drains to catch those flying around. They will fly in and drown. Replace every day or every other day as needed.
Using Insecticides
Insecticides can be a powerful tool in the fight against drain flies.
Peppermint, eucalyptus, and tea tree oils are especially beneficial. Pour a few drops of the chosen oil with water down the toilet. The oils' pungent aroma repels drain flies and disturbs their breeding cycle. To keep the solution effective, reapply it every few days.
Answer: Bug bombs will kill flies that are exposed at the time the bomb is used. The products cannot kill hidden flies or fly eggs.

Fly Control Inside the Home: Flies inside the home are best sometimes treated with synergized pyrethrins or synthetic pyrethroids in aerosol or spray form. These materials give quick knockdown and kill of flies but do not provide lasting protection. They are most effective when applied into the air of closed rooms.
Vinegar and baking soda: Pour 1/2 cup baking soda and 1 cup of vinegar down the drain.
Drain flies thrive in stagnant and standing water. Common sources include slow or clogged drains, rarely used and unused toilets, refrigerator drain pans, and standing water created by leaking pipes. They typically enter buildings through basements, windows, and drains.
The simple answer is yes but with a caveat. While bleach can kill drain flies and their larvae on contact, it's not the most effective method for long-term control. Bleach's caustic nature allows it to clean the drain pipes and kill some of the larvae.
If your drain fly issue persists, consider using commercial drain cleaners such as Drano. These solutions are formulated to clear out the drains and pipes effectively, removing any debris that might serve as a breeding spot for drain flies. Using these products can aid in preventing new eggs from hatching.
Drain flies, also known as moth flies or sewer flies, are small, hairy, moth-like insects measuring 2 to 5 millimetres long depending on the species. They are weak fliers and are often seen walking near breeding sites. Females lay 30 to 100 eggs in masses on the surface of breeding medium.
It kills flies (such as houseflies, bottle flies, drain flies, fruit flies), gnats, mosquitoes, moths, wasps and hornets in one easy spray. This Raid® flying insect spray is part of a complete line of products to target specific insects inside and outside.
During the day, adults rest in shaded areas or on walls near plumbing fixtures and on the sides of showers and tubs. Most activity occurs during the evening when these flies are seen hovering about drains and sinks.
Pouring boiling water is quite risky as it might lead to a steam burn or scalding. Another thing to keep in mind is what type of material you are pouring in into. If you have a porcelain sink, it is likely to crack due to the heat. All in all, pouring boiling water down your drain will only cause issues down the road.
The Santeen Sulfuric Acid Drain Opener proved to be the most potent among all the chemical drain cleaners we tested, effectively dissolving 80% of the hair, 80% of the organic matter, 40% of the grease and 76% of the paper products.

Knowing the life cycle helps you fight fly infestations. Life Cycle: Adult females lay 30–100 eggs in sludge around sewage and drainage areas. Eggs hatch in 32–48 hours, larval stage lasts 8–24 days, pupal stage 20–40 hours. Adults live about two weeks.
Mix together 1/2 cup of salt, 1/2 cup baking soda and 1 cup of vinegar. Pour the mixture down the drain. Let sit overnight, then flush the drain with hot water in the morning.
Drain flies feed on filth and scum that can build up in areas such as drains, drain openings, sewers, septic tanks, and kitchen sinks. A great way to identify which drain-source the flies are coming from is to put clear tape over the drain so that they will fly into it and get stuck.
HydroScrub® Jetting is one of the most effective professional cleaning services available today. This system uses highly pressurized water—we're talking around 3,500 PSI—to blast all debris within your pipes into the city's main sewer line.
Furthermore, there are essential oils that have insect-repellent properties, which can help deter drain flies, including peppermint, eucalyptus, and lavender oils. To use these oils as a deterrent, just dilute a few drops in water and use a spray bottle to wash down the areas that are infested.
This Green Gobbler stuff really does work. The drain flies were gone in one day. 32oz was barely enough for all the drains in my home for one application. I ended up using two bottles and while the fruit fly population dwindled for a week or so, it exploded back to where it was before I used Green Gobbler.
Lavender, eucalyptus, peppermint and lemongrass essential oils – Not only will spraying these oils around the house create a beautiful aroma, but they will also deter those pesky flies too.
The best homemade fly trap is one that can attract both house flies and fruit flies. To lure both outdoors, mix scraps of rotting meat, like fish or chicken, with sugar or honey. When indoors, the best bait is old fruit or honey. Liquid dish soap is exactly what you need to drown the flies.
