What Do Drain Fly Eggs Look Like
Drain fly eggs look brown or cream-colored and can hatch within 32 to 48 hours. Female drain flies lay their eggs in wet, organic matter such as found in drain traps and garbage disposals. They can lay between 30 to 100 eggs and their larvae and pupae exist inside the slime layer in your drain.
Once hatched, pale white larvae will feed on organic material within the drain. Drain fly eggs can mature to adults in seven to 28 days.
Clean Your Drains Carefully
Regularly cleaning your drains will kill the larvae and the adult flies. You can opt for a commercial cleaning productsuch as a bleach solution or a chemical cleaneror a do-it-yourself , environmentally friendly solution.
One such recipe calls for homeowners to pour one cup of white vinegar and a pot full of boiling water down the drain to disinfect it. Be careful if you choose this method because hot water could splash back up on you.
Baking soda is another effective household drain cleaner. You can mix a half cup of baking soda with a half cup of salt, half cup of lemon juice, or a half cup of vinegar for an environmentally friendly disinfecting option.
If your drain fly problem persists after a good cleaning, the flies may be living deeper in your pipes. In this case, you may want to invest in a pipe brush. These brushes feature stainless steel bristles attached to the end of a flexible pipe designed especially for home drains. You can scrub out the buildup in your pipes using these tools.

That also includes cleaning your garbage disposal unit and not allowing food waste to accumulate in your sink.

Where Does Drain Flies Come From
Finding and removing the drain flies water and food sources is the key to preventing them from getting into your house. You can accomplish this by setting up easy-to-set traps utilizing an insect adhesive board or a plastic cup.
When using the plastic cup technique, lightly cover the interior of the cup with petroleum jelly or vegetable oil before inverting it over the drain where you think flies may reside. Check on it every day while leaving the cup in that spot for several days. Flies will start to gather on the inner surface of the cup if there are any residing in the drain.
Making a cardboard frame to hold a glue board over a drain where you think drain flies might reside is another option. Place an upside-down insect glue board on the frame. Check the board every day while leaving it in place for a few days. Most likely, flies coming out of the drain will stick to the adhesive board.
Whichever style of trap you choose, be sure to inspect it often. Set the trap to some other potential location if no flies are found there after several days. Take your hunt to the outside and look for any regions with moisture and rotting material if you are unable to discover a supply inside the house.
What Are Fruit Flies
A fruit fly is a small fly that feeds on fruit. Adult fruit flies actually lay their eggs embedded in decaying organic matter or on the surface of overripe fruits. For these reasons, overripe or decomposing food is the number one culprit of causing fruit flies in the home.
Fruit flies live off of the juices of fruit, which give them sustenance, nutrients, and energy. The more time a fruit fly has to feed off the fruit, the more the fly will mature into its adult self, becoming ready to lay its own larvae.

Pour 1 cup of liquid white vinegar into the drain, where it will begin a foaming action with the baking soda. Allow the mixture to work overnight to kill any remaining larvae. In the morning, pour some very hot water down into the drain to rinse it and any remaining fly larvae away.
There are also a variety of biodegradable drain gels and liquids that will thoroughly clean the pipes, eliminating the breeding ground for drain flies. Try to avoid using chemical cleaners, however.
