There are a lot of small black flying insects in the toilet, very small, like small moths, which can

The scientific name of this small flying insect: moth midge, commonly known as "fecal worm", is a small insect that breeds in septic tanks and sewers.

Insecticidal methods: 1. The eggs and larvae of moths can only grow in a humid environment, so it is necessary to check the damp dead corners in the room, such as: water basin pillars, toilet tanks, washing machines, etc.

2Keep the room ventilated and dry, and do not store clothes, mops and wooden furniture in the toilet. 3. Check the sewer pipes to have a backwater bend. There are also a few things that are easily overlooked:

There is an overflow hole in the sink, which should be flushed with hot water frequently; If the toilet bowl is flushed with a basin, there will be a void phenomenon, resulting in a gap in the backwater bend, which should be filled with a small flow of water; The sink in the floor drain will dry out due to heating baking, so it is usually covered with a rubber pad; The connection between the toilet bowl and the ground should be sealed with glass glue, do you see the fixing holes on both sides? A lot of bugs came out of there!

There are a lot of floor drains in the bathroom. Washbasin Floor drain for bathing, if convenient, change to an odor-proof floor drain so that bugs don't like to breed in dark and damp places. Also, look around the sewer pipes to see if there are any gaps.

If you're on the first floor and there are a lot of pipes, look closely.

Try spraying some mosquito repellent, then close the door for an hour or two, then open the door again, let it ventilate, and then observe the floor, if there are any dead insects, yes, it proves effective, no, just find another way.

Rinse away the nutrients from these feces and urine, and then try to disinfect them with toilet cleaners.

1. Place a sticky board in the toilet to keep the bugs sticky.

2. Use insecticides to kill flying insects.

3. Use disinfectant to disinfect the toilet.

4. Use an electric mosquito swatter.

5. Environmental sanitation methods: every 10 15 days use a small brush to scrub the sewer outlets and tile wall gaps in the kitchen, bathroom, bath room, and scrub and remove the gnats eggs or pupae hidden in these places, which is the best way to prevent and control them.

It's usually only found in damp places, so it's impossible to have it according to the method you said?

Spray insecticide on the floor drain, then spray in the space, close the door and window for 8 hours and then ventilate, it should be fine!

Insecticide hold it for more than an hour + ventilation, this kind of slave is basically the master who will be finished without moisture, so usually pay attention to ventilation and exhaust, etc., and pay attention to the cleanliness of the toilet.

Because that's what comes out of the sewers, it's called the grasshopper, and the sewer is the source of the grasshopper. You can plug it with something or use a drain for sewers.

The walls and floors should be very clean and equipped with screens. Use detergent to drain the drains, close the doors and windows and clean them with insecticide. I believe it works well.
