Yes you definetly want to keep it in check, right now one is taking over the back of dads house, because i havent gotten to rip some of it down.
Also not to freak anyone out, but when new shoots start out, there 3 leaves, and they look just like poison ivy. I think its a defense mechanism the plant has. Other wise it changes into 5 leaves then. So i always have to look and make sure its not poison ivy i am pulling.
