Danged Squirrels in the attic!

[Voyageur]

Any tips on getting rid of squirrels that attic that keep seeming to find their way in despite my having blocked off all evident entry holes. Have also tried the ultra sonic remedy and moth balls (I know, I know.... but I was desperate!) and nothing has worked so far :(
