Asian beetles

I was reading something about asian beetles(you know those little beetles that get in your house that kind of look like lady bugs) that says a compound made of catnip oil appears to repel them. I wonder if you put sprigs of catnip or catnip oil on a cotton ball on your window sill where they find their way in, if it would help to repel them. Peppermint oil on cotton balls repels mice so maybe it would help. I'll try to remember to try this next fall and let you know how it goes.
