You might be out of luck as some of the Biologist say that nothing short of an atomic blast would get rid of them :cry: :grin: :cry: :grin:
With this in mind...seems that the leveler headed IMO say that you should try to control them. If you attempt to eradicate, or kill a bunch of them, you will get a bunch back as per the litter cycles and such.
I personally will take a coyote when the fur is prime and make sure to get it skinned out right away. If there is trouble with livestock, or even cases of the yotes hurrahing the isolated farm houses I will take them anytime.
