We have been plagued with those little pests for 12 to 15 years now. Everybody blames the DNR for importing them to take care of another pest we have. They (DNR) adamantly denies it.
They have no enemies that I know of, so they just keep multiplying. When disturbed they stink so bad nothing will touch them.
They're not Lady bugs, even tho they look like them. I believe the correct name is Asian beetles. They also will bite!
As stated, some years they are worse then others. Seems like in the fall whe the weather starts turning cooler, they start making an appearance.
