What are the signs of bats nesting at home?

1, if the family flies into the bat's nest, it is actually a good omen, indicating "happiness" and good luck.

2. Bat is called "Rat Fairy" among the people, but it has always been regarded as a symbol of good luck, because "Bat" and "Fu" are homophonic, representing good luck and happiness.

We all know that bats hunt by ultrasonic waves, so sometimes bats may fly into the house to hunt insects, but it is also possible that bats may nest at home because of the type of room or the home environment, so be careful.
