Make a natural cleaning/fly killer mixture. 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. This should kill all flies and the organic material they've been feeding on.

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.
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.
We chose apple cider vinegar as the bait, but use whatever you have on hand. Luckily, flies are attracted to anything sweet — old wine, sugar water, ripe fruit, honey or syrup are some of best bait for a homemade trap. You'll also need dish soap, which helps drown the flies in the liquid.
Homemade fly killer spray: A mixture of half a cup of water, half a cup of isopropyl alcohol, and a teaspoon of dish liquid can be filled in a spray bottle. This mixture can be sprayed on the flies directly to kill them.
Boil a pot of water and pour it down the drain where you suspect the drain flies are breeding. Pour a 1/2 cup of baking soda down the drain. Slowly pour a 1/2 cup of vinegar down the drain. Cover the drain with a drain plug, and let it sit for at least 5 to 10 minutes.
A bottle of wine, beer, vinegar, or ketchup works great for this kind of trap. Get some plastic wrap, or even a plastic baggie, and cover the top of the bottle snugly. Poke a couple of holes in the plastic using a pen or similarly-sized tool.
Mix either vinegar or sugar with washing-up liquid, then pour it into a Mason jar. Cover it with clingfilm, and add a few tiny holes. The sweet smell will attract the flies, and they will crawl inside the jar — but they won't be able to get out.
Vinegar and baking soda: Pour 1/2 cup baking soda and 1 cup of vinegar down the drain.
Create a fly and wasp repellent.
This DIY pest repellant should be a staple in the Southern home. Pour equal parts water and Pine-Sol in a spray bottle to spritz on outdoor furniture, the deck, and indoor areas where flies are most likely to flock, such as kitchen countertops.
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.
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.
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.
Combing, boiling water, vinegar and baking soda will kill drain flies, but will also help remove all the flies breeding ground which includes hair, grime and grease. It will create a chemical reaction and an clear the blockages caused by organic matter in the drainpipe.
Fill a cup or small bowl with white vinegar or apple cider vinegar for flies, then add a few drops of dish soap. Cover the bowl with plastic wrap, and secure it with a rubber band. Poke holes in the wrap to create entry points for the flies.

Pour in 1/2 cup of salt and 1/2 cup of baking soda plus a cup of white vinegar. Allow it to work its magic overnight then flush the drain with hot or boiling water the next morning. This will sanitize the drain and kill the flies and their eggs.
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.
Choose from either chemical sprays, household cleaners, or hairspray. Chemical sprays kill flies instantly upon contact, though they contain harsh chemicals. You can also spray the flies with household cleaners, like Windex or Formula 409, or with an aerosol like hairspray. All of these sprays will help you kill a fly.
Combining two tablespoons of dish soap, four tablespoons of apple cider vinegar and six tablespoons of water involves nothing more than a quick stir. After that, we're adding a piece of plastic wrap and securing it with a rubber band. Last step is to poke the wrap a few times with a toothpick.
