How do I find the yellow jacket nest in my back yard??

Lots of bees, I tried to feed them some sweet foods, so I could watch where they take it to, but they seem un-interested in eating. I watched them for like 5 mins until I got scared and was feeling non-existant bees stinging me.... Is there a better way to find their nest?? Is there something they really like to eat, so I can follow them back to the nest?? They fly in some crazy algorithm that I have a hard time following, so I lose them quite often. Any help would be great!! I know how to kill them once I find the nest, so please don't answer on how to kill them, just to find the nest.... THANKS
