Generally speaking, the middle part of the carpet is not easy to be worms, and the corners and the surrounding area of ​​0.3-1 meters are prone to insects, because this part is not often pressed, there is a certain space in contact with the ground, and there is dust and air. Allow the carpet worm to survive. However, all parts of the carpet that is handed over and pulled may have insects. This is because there is a gap between the latitude and longitude lines behind the carpet, and it can still flow into the air after contacting the ground. In addition, carpets laid on wooden floors are more susceptible to insects than carpets laid on cement, tiles, and terrazzo. The reason is that the wooden floor is easy to absorb moisture, thus providing the growth conditions for the insects. The part of the carpet that is pressed under the furniture is also a part that is prone to insects. To prevent carpet worms, the solution is: (1) Keep the carpet clean and dry. After the carpet has been used for one year, it should be moved outside, knocked off the dust, and aired, but do not expose to the sun. When the carpet is re-applied, the floor should be cleaned. (2) After two or three years of carpeting, it should be cleaned once with chemicals. After washing the carpet, if it continues to be used, the floor should be cleaned and then laid. (3) It is best to wax the wooden floor. After two or three days, spread a layer of sanitary sphere on the floor and then lay the carpet. (4) When storing the carpet, spread the sanitary sphere evenly on the carpet, then wrap it tightly and put it in a ventilated place. It is best to place it at a height of half a meter to one meter above the ground.
