What should I do if there are many lice on the bed?

These things on the bed are probably dust lice. If you want to eliminate dust lice, you can use the following methods:

First, dust lice are afraid of high temperature. Dust lice live in every area of the house every day. Where there is floating dust, there are dust lice. If you wash the sheets and pillow cores with boiling water at 55 degrees Celsius every week, the dust lice will die immediately. The optimum humidity for the growth and development of dust lice is 75 ~ 80%. If the humidity is reduced, the total number of dust lice can be reduced.

Secondly, pyrethroid insecticides have strong contact toxicity and stomach toxicity, and are quick, long-lasting, convenient to use, can be diluted with tap water immediately, can make full use of drugs, have good dispersibility, are safe for small animals, have no irritating taste, and have antiseptic and destructive effects on the surface of objects. It also has a certain ovicidal effect. It has a high contact killing effect on lice. If the dust lice, bed lice and book lice are serious, the dosage can be increased, and the maximum dosage is 65,438+0.20 ml/sprayer. Then open the bedstead completely, take out the joinery board, and expose the load-bearing beam of the bed board. If the load-bearing beam needs to be removed in the middle of the wooden bed, then the intersection is the key area where dust lice, bed lice and book lice lay eggs.

Third, be careful when spraying. Especially at the joint between the bedstead and the bedplate, there is still a gap between the laser cutting surfaces of the bedstead, which hides dust lice, bed lice and book lice. Then, check the wall and ceiling, but the black spots on the wall are all concentrated areas of dust lice, bed lice and book lice. These small black spots are the areas where bedbugs usually defecate, and there will be many larvae. Generally, wall holes and steel nail holes are dust lice, bed lice and book lice. Immediately after the end of the standard to eliminate masonry cracks, reduce cracks.

Fourth, clothes and trousers should be cleaned and exposed to the sun to avoid residual larvae. After spraying the medicine, you can enter after closing the window for 3 hours. After 3 hours, you can go in to eliminate cleanliness and hygiene, and immediately check whether there are residual dust lice, bed lice and book lice in the clearance gap.

In a word, the above methods can eliminate dust lice very well.
