Miss Wang, who lives at the crossroads, has been laying a mat on the bed since the day before yesterday. Although the mat has been sun-dried, she has red blisters on her body after getting up every day, which makes her very worried. Mr. Li of Huangjiawan also said that his skin condition has been very good. Not long ago, he bought a new reed mat when he was doing activities in the supermarket. After only one day, a lot of red spots appeared on my body, which was extremely itchy. Fulai medical experts explained that sweat soaked in a mat for a long time is easy to breed mites and bacteria. Compared with bamboo mats, rattan mats and cowhide mats, it is more comfortable and safer to use. When you buy a new mat, you must expose it to the sun and clean it. Ms. Zhang from Wuchang Yangyuan has more experience in this field. Before putting the sleeping mat away, use a spray gun to fill it with insecticidal water, spray it on both sides, then roll it into a tube and seal it in a plastic bag, so that the mites will suffocate and die. When you use it next year, water the mat with boiling water and then dry it in the sun. There are no mites. Chen, a retired worker, knows how to control mites. Before the arrival of summer every year, she would go to the park to pick up the maple fruits on the ground, pick out 20, cook them thoroughly in water, then wash the mats with maple juice and dry them.
