Asian Lady Beetles,...I have choice words for the idots who brought them here....Live close to the soy field, so We have an infestation twice a year....Have developed an intolerance to anything that has soy in it and have wondered if this could be the cause....Swell up like a ballon when one of those little bugs bite me.
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!
