How to Get Rid of Drain Flies | Do It Yourself Pest Control


Have you ever faced the problem of flies coming out of the pipes or drains in the bathroom or kitchen? The smell of perishable materials usually attracts these small drain flies, Diptera insects from the Psychodidae family, creating the ideal breeding environment for these so-called drain flies. If your drain has clogged pipes or drains slowly, drain flies could be the cause, and there could be an ongoing infestation by these pests if they were laying their eggs in standing water. Wondering what the drain flies are like? They are also known as moth flies because they resemble small moths. The size of an exhaust fly is between 1.5 mm and 5 mm. They are also known as sewer flies. In general, these flies are not dangerous to humans if there are only one or two in the bathroom or kitchen. In any case, if their numbers were to increase there would be risks for the food because these insects carry traces of organic material with them. In some cases, they can lead to bronchial asthma in humans. For all these reasons, if you are facing an infestation and are looking for ideas on how to get rid of drain flies in the bathroom or kitchen, then you need pest control surgery. Instead of spending some money on professional pest control, you can learn how to get rid of flies at home thanks to the do-it-yourself solutions to clean the drain contained in this project. The only ingredients you need are hot water, white vinegar, water,

Note: Before encountering these methods I tried using bleach diluted with water to get rid of drain flies with no great success. Does bleach get rid of exhaust flies? The answer is yes. You can dilute it with water and pour it down the drain. However, the problem with using bleach is that it flows too quickly down the drain and therefore does not eliminate the formations of organic materials that form on the walls of the drain, walls that house the larvae and eggs that may be present. Instead, I recommend using DIY systems to get rid of drain flies.

How to create the drain cleaning solution

First of all, put about 20 grams of baking soda in a container.

Mix with salt

Then mix the salt with the baking soda.

Mix with 170 ml of vinegar

White vinegar is known for its acidic nature and for its disinfectant properties. Pour 170 ml into the bowl and mix well.

Pour the solution down the drain

Now pour the cleaning solution created into the container down the drain and let it act overnight. Make sure you don’t run water down the sink or shower, as the water will only dilute the solution and decrease its effectiveness.

Pour hot water down the drain for a thorough cleaning

The next morning it’s time to pour hot water down the drain to unclog it. Let the water run down the drain to unclog it and clean it completely. Hot water also serves to dissolve the grease and dirt that cause water stagnation or slowed water drainage. This way the infestation should be stopped. However, if the larvae were to remain in the stagnant water you could still find drain flies. In this case, you might consider creating a fly trap discussed below.

Create a DIY fly trap

Put about 20 grams of sugar in a bowl.

Add water

Then add about 20 ml of sugar water.

Add vinegar

Add about 20 ml of white vinegar to the bowl.

Add some dish soap

And finally, add 5 drops of normal dish detergent to the bowl and mix the ingredients until the sugar has dissolved.

Put the fly solution near the drain

Leave the fly solution in an open container near the drain for a few days. You will notice drain flies being trapped by the solution. You can cool the solution after a few days and keep it near the drain for a few more days until you see no more flies in the container. In addition to these DIY anti-parasitic methods for getting rid of drain flies from your home, it’s essential to keep the drain clean with a regular, thorough cleaning to make sure the flies never come back. Here are some tips to follow:

Scrub areas adjacent to kitchen and bathroom drains to prevent dirt build-up.

Use a bio-enzymatic drain cleaner once a month to remove grease and dirt from drains. If drain flies do not find organic materials to feed them, they will not reproduce in the drain. (If you make compost at home, you can also take the leachate from there and pour it undiluted down the drain to keep it clean.)

Eliminate all stagnant kitchen and bathroom water. In some cases, a broken tile could be the cause. If so, fix it to prevent drain flies from reproducing under the tile.

Empty the garbage containers daily and wash them with hot water to clean and disinfect them.

If you have sinks or a bathroom that you don’t use often, still run hot water down the drains at least once a week to keep them clean.
