In August 2020, one night, the house suddenly heard the cry of a cockroach, I listened carefully and found that he was calling on the balcony, the cockroach was not big, but its call was very regular. And so every night after that I would hear him crying in different parts of my house. Strange to say, I, a person who does not sleep well, fell asleep listening to the clams and listening to them. I chased his voice every day to give him food, and I don't know if he ate it? After a short time, probably more than a month, I could no longer hear the cry of the cockroach, and I don't know if he ran away or died. In July this year, I started to sleep badly again, and I thought about cockroaches, so I bought two oil gourd icons online, and then bought two beautiful cockroach cans. Made a home for these two little ones. He took turns calling every night, the smaller clams began to bark at about 8:00 p.m., the larger ones started calling at 9 o'clock, and the most cheerful at 10:00 p.m., the crisp and magnetic sound brought vitality to this quiet night, and also made this hot summer cooler.
