Stork,
You do any trapping? Buy a furtakers license, and get A ribcage of a deer or other big deer part with a little meat on it (If its legal ) that you could get from a butcher and hang it about 4 ft off the ground in a tree with about 6 to 10 #3 leghold traps bedded around ....that should do the trick. You could just lay it on the ground, but you will only catch one at most as they just drag the carcass away, plus you have the chance to catch skunks, possums etc that you wouldn' t catch if it' s off the ground.
If you have that many Yotes around catching them would be a pice of cake.
Stagger the traps so that you don' t catch the same animal in 2 or more of the traps and waste the sets. As they jump to get at the meat they will pay no attention to where there feet are landing.
You could also end up with an entire pack waiting for you when you check them.
Make sure you have at least a .22 mag to tack each one from a distance.

Check your regulations and see if you can catch them in this manner.........trapping is really addicting! And Coyotes are bringing about $25-30 I think. It' ll pay for your traps.
