Larvae is slender and cylindrical, full-headed, footless, with petals or posterior petals at both ends. Body 12~ 14, there are many ossified fragments on the back of the body. The ventral surface usually protrudes to help it move, and the valve at the back is located on a short tube. The body is bristly or rod-shaped, and the abdomen often has long hair or brushes. Aquatic larvae also have tracheal gills and sucker-like attachment structures. Larvae are mostly saprophytic or dung-eating, living in rotten wood, rotten grass and soil, some living in sewers, and common indoors after emergence.

Prevention and control of larvae

The application of insect growth regulators in sewage ponds will interfere with the Hermon balance in the life history of insects, making their larvae unable to molt and pupate smoothly, thus making waterways and swamps develop into adults to mate and reproduce the next generation.

In places that are difficult to access or destroy, such as sewage ponds, septic tanks, sanitary lowlands, etc., our company uses insect growth regulators imported from Japan, so that insect larvae can not shed, pupate and emerge into adults to continue reproduction, thus achieving the control effect. It is usually effective, low dose, odorless, convenient, bio-friendly and does not contain fish in water. Insect growth regulators imported from Japan are used together with acaricide to achieve faster and more comprehensive control effect.

Moths mainly breed in all kinds of stagnant water. As long as the water in the container is emptied and the outdoor ditches are kept clear, the number of moths can be controlled.

Using pyrethroids to spray bathroom walls and underground can generally last for more than 15 days.

This kind of insect is mainly produced from the sewer, so the sewer must be effectively isolated with a real odor-proof floor drain and sealed tightly. The vegetable basin, washbasin, washing machine, shower room, bathroom and other places should also be sealed without leaving any exits, so as to isolate flying insects from the sewer.

Spray the pesticide in several places.

====

Spray pesticides around the toilet. It doesn't matter if you spray too much. Then cover it, preferably sealed. It'll be all right in a minute. I've also found this phenomenon, and it's gone after doing this.

======

I went to the drugstore and bought a small bottle of potassium permanganate for 1 yuan. Then I went home to find a watering can, put a few tablets in it and spray it with water. The purple ones will be disinfected with hot water after spraying.

The floor drain in my bathroom can sometimes be found. I did so, sprayed it near the floor drain, and washed it with boiling water later, and it was never found again.

======

Pay attention to the trash can and damp place at home, and be sure to keep it clean and hygienic! You can kill it with an ordinary mosquito killer! The garbage baskets in the kitchen, living room and bathroom must be replaced in time to avoid their reproduction. There must be garbage baskets in your house that have not been cleaned in time, so remember that garbage baskets with fruit skins are the easiest to attract them!

==========

Disinfectant! 84 disinfectant! Dilute it. Let's go !

It is best to clean the bathroom floor with boiling water, especially in places like floor drains.

Then use diluted 84 solution-this can't be boiled water-and then rinse! !

The bathroom is waterproof, so don't worry about it. Rinse thoroughly before drying.
