I hate them, too. I have an exterminator in every October 1st.
It guarantees I am vacuuming up dead ones. A month in the Fall and another month in February as the hardy ones that got in try to get back outside. In the outbuildings, they still manage to get in every Fall, despite the spray, so I am vacuuming thousands of them until June.
I hate the stink when they are vacuumed. The bite doesn’t bother me, though.
I blame the University Extension biologists. They imported the buggers to control aphids. Worked, but nothing will eat the Lady Beetles!
University Entomologist....I knew one at Purdue, neighbor of the homeplace...He even admitted they were “causing a great deal of problems for homeowners.” but had helped the farmers considerably.
In the spring I just open the windows and they are gone in a very short time....Have bought a shop vac just for the little buggers.... Some years are worse than others.
