Things like mole crickets are insects that live underground and are also phototropic, flying towards lights at night. There is nothing strange about the appearance of this thing at home, it may be crawling out of the vegetable garden next door. There's really no reason why it's lucky or bad luck to see a certain kind of animal, and there may be different customs in different places. The Buddha said that all beings are equal, mole crickets are also beings, there is no relationship, do not believe in these.
