re: anyone recommend a poison for coyotes?

Cut pieces of sponge in 2" squares. Put a few drops of blood and a few drops of bacon grease on the sponge. Do not let any domestic dogs that you might care about get anywhere in the area. When the sponge is eaten the dogs can not pass it and they will end up dying. Do not use Temic! It is way to hard to control what eats it. It also kills what eats the original target.

Another method is a treble hook and steel leader hanging 6"-10" above normal reach of a yote. Tie the rig in such a manner that the yote has to leap for the bait. When he leaps for the bait he should either be swinging or back feet barely touching. This predicament doesn't allow for any pull or fighting the hook. He will be there the next time you arrive either nearly dead or all the way dead.
