1, flies are animals that feed on carrion or some sweet and greasy food, so when flies suddenly appear at home, it means that kitchen waste has not been cleaned up, such as rotten leaves, leftovers or desserts. If the home is clean and tidy, and there is no smell at all, it may also indicate that the feng shui fortune at home is declining.
2. If it is hot summer, it is normal to have flies at home. So don't panic, just open the window and clean it frequently. As long as the indoor air is fresh and clean, one or two flies are generally not a problem.
Flies generally give people a bad impression, so flies suddenly appear at home. If it is not an environmental problem, then most people will think of Feng Shui and fortune. But in fact, flies have little to do with feng shui, so if one or two or a small number of flies suddenly appear at home, it may be the weather. But if there are many flies, remind you to clean the corner of the room to see if there are any dead mice and animals.
