2. Realistic perspective. Bats flying into the house may be an ominous sign from the perspective of real life. Because bats prey on ultrasonic waves, sometimes bats may fly into the house to prey on insects, but it is also possible that bats may nest at home because of the type of room or the home environment. Therefore, whether bats go into the house to hunt or nest, it is not good for daily life.
3. From a scientific point of view. According to scientific theory, it is actually a very accidental phenomenon that bats enter the home. Because bats probably came in by mistake because they preyed on insects, because everyone knows that bats rely on ultrasound to tell their direction.
