What Do I Do When Locked out of My Own Jungle?

This is happening more often than not.

I go jungle and the enemy team just wards nothing but my jungle just to keep me from farming. Enemy laners will disappear out of lane just to go in and kill me at one of my own camps while my allies farm without pinging an mia.

Sometimes my allies will have the map awareness to at least avenge me by going in after whoever killed me, but it isn't enough to make up for lost time, gold, and exp.

I can put a control ward down somewhere to try and soften the difficulties, but I can only have one down at a time. And going back to place a new one down just so I can farm is gold inefficient.

Eventually, I can't level, I can't help anyone, and everyone hates me.
