Where did the little black bug that jumps on the washbasin come from? What should I do if there are small flying insects in the washbasin?

The wash basin is usually in the bathroom, which makes it convenient for daily washing. The sink is also a place that cannot be ignored in our daily cleaning, otherwise it will form thick yellow stains and even attract some small flying insects. Generally, when these small flying insects and small black insects appear in the bathroom, it means that there is no dead space in the bathroom that has been cleaned up, so how do these small insects come from?

Where do the little black bugs that jump on the washbasin come from

It usually comes in from the sewer. The bugs are called moth gnats, and most of them emerge from septic tanks, septic tank holes, cesspools or toilets, drains and drains. Because gnats grow in septic tanks and sewers and are covered in fine hair, they can easily carry germs and even pathogens. When they fly into a room, they can easily spread disease if dropped on food. Moth gnat larvae live mostly in aquatic habitats (usually low-oxygen places), including bathtubs, sinks, etc. They are common harmful pests in bathrooms.

What should I do if there are small flying insects in the washbasin

Pour an appropriate amount of caustic soda into a small bowl, soda ash can eliminate the sink drain flying insect eggs. Then pour some detergent, and pour boiling water to dissolve it evenly, and then pour it into the sink drain. You can also add sugar and a small amount of water into a beer bottle, and then shake it up so that the sugar can fully hang on the wall. At this time, put the beer bottle down on the sewer mouth, so that when the small flying insects fly out, it will stick to our beer bottle. You can also use a flashlight to illuminate it to attract small flying insects to fly out. These insects have certain phototaxis.

Why does the bathroom smell?

1. The bathroom is wet for a long time, which is easy to cause odor, so it must be opened frequently Windows for ventilation. For toilets without windows, an exhaust ventilation system must be established. Frequent exhaust air can effectively eliminate odor and pollution from the toilet. Of course, when doing the exhaust system operation, don't forget to install the check valve, otherwise the exhaust will not only block the exhaust, but also cause the exhaust in the duct to flow back into the toilet, which will have the opposite effect in the toilet. 2. Put some green plants in the bathroom that can absorb pollutants and have dehumidification effect to purify the air and beautify the bathroom environment.
