This kind of bug called moth often appears on the walls of kitchens and bathrooms, the whole body has a lot of fine hairs, easy to carry pathogens, has the ability to infect food and spread disease.

Moth activity is not high, the ability to transmit mechanical disease is small, has the ability to spread disease caused by Escherichia coli. But what if you can't get rid of this disease? Today, we will guide you a small method, just pour it into a bowl, all kinds of black moths with bad smell will be eliminated.

Method 1, first we use the remaining cigarette butts soaked in water, put the cigarette butts in water, stir well to increase the dissolution speed, cigarette butts contain nicotine and tar, which are very effective in killing insects or repelling mosquitoes. And the soot on the cigarette butts has good adsorption capacity, which can increase the effect of killing insect eggs.

When the water turns yellow, we scoop the cigarette butts and pour them down the drain, to kill the eggs in the drain, kill the roots and eliminate small flying insects in the pipes. Pour a bowl of cigarette butt water down the drain every week to keep the house clean. And soaking the cigarette butt water down the drain is not only free but can also turn waste into 'treasure', it is a good way that you should try.

The second method, first we use a wet towel rolled around the floor drain, then align the mouth of the insecticide pipe with the mouth of the drain and spray a few times, use a wet towel to wrap around evenly, spray insecticide to prevent odors from escaping.

After spraying, we use this wet towel to seal the floor drain and open it again a few hours later to kill small flying insects in the pipe, this is a very practical method.

Third method, we prepare a kettle of boiling hot water, then pour it into half of the drain, to destroy the oil slick in the drain and the bug eggs that exist in the drain.

Then we prepare a container, pour about three spoons of glutinous rice flour into it and squeeze two drops of dishwashing liquid into it. We dissolve them in hot water, adding a little water will be more effective. Next, we let the flour melt completely.

Then we flush the alkaline water directly into the drain. The alkalinity is very strong, it can kill the eggs in the drain, and the detergent is used to better clear the drain and prevent the drain from smelling! After our water is drained, we will see a lot of heat coming out of the drain, and we need to wait quietly for five minutes.

Then we boil a pot of hot water and pour it all down the drain, we clean it once a month to make sure your family won't have little flying insects all summer long!

Tiny Black Flies on Bathroom Walls? What They Are, Why They Keep Coming Back, and How to Get Rid of Them

Have you ever walked into your bathroom, turned on the light, and noticed several tiny, dark, fuzzy insects resting quietly on the walls? They may look like miniature moths, with small wings shaped like hearts or leaves. Sometimes they barely move. Other times, they flutter around the sink, shower, or floor drain.

Many people assume these insects are harmless mosquitoes, tiny moths, or some kind of flying pest that has entered through a window. In many cases, however, they are drain flies, also called moth flies or sewer flies.

Although they are small, drain flies can become frustrating when they appear repeatedly in bathrooms, kitchens, laundry rooms, and other damp areas. Seeing one or two occasionally may not be a major concern, but finding several every day can indicate that a suitable breeding environment exists somewhere in the home.

The good news is that drain flies can usually be controlled without expensive professional treatment. The most important step is not simply killing the adult insects you see on the wall. It is finding and removing the organic material where their larvae develop.

1. What Are Drain Flies?

Drain flies belong to the family Psychodidae. They are very small insects, usually measuring only a few millimeters in length.
