The leakage of balcony eaves counts as property.

From my previous experience of stirring up a hornet's nest: 1, the wasp will not retaliate, just come back to find a home and fly away if it can't be found; 2. More than one will definitely fly back. The key is that you don't pay attention to it deliberately, and it will be gone in two days; Spray some medicine in the place where the hornet's nest was originally made, so as not to recreate it. (But this year basically won't nest in the same place. )
