I remember years ago when I lived about 100 miles north of where I am now and we had those ladybugs or beetles. THEY WERE EVERYWHERE!
My daughters would use the vacuum and suck them up. It was awful!
They were like a growth on the outside of my farmhouse. I don't miss them at all. But this year we were swarmed upon by box elder bugs! Just as bad... sigh
HAHA...yeah I have used a vacuum before. They stink when you squish them!
