In life, we often find that flies fly around the ceiling lights in the house. Why do flies like this? In fact, flies do not do this, but it seems to be doing it. This is because you only notice them when they bother you. The truth is precisely because you just caught them there. Otherwise, they will still stop in the same place and continue to do the disgusting thing of spreading the disease.
However, once in the air, they do seem to always like to fly around the center of the house, unless the outside is the bright day they prefer. There is a view that they don’t like corners, they either use the lights as a high ground for attacking competitors or to attract spouses. Female houseflies that inhabit the lamp are disturbed by males patrolling in nearby space, and the males begin to compete for the highlands, from where they can rush out to drive away any other flies that threaten their airspace.
If you want to retaliate against the harassment of your flies, here is a fun game: the next time you see a housefly purposefully hovering under a light on your ceiling, put a fake fly (a fly) The size of the paper can be thrown at it. The fly will almost immediately leave the hovering water level to chase the “invader” because the arcuate orbit of the “invader” invades its airspace.
