I have never used snares, but have heard they work well. Set them out where the coyotes are coming under fences. Snaring one around the neck is preferred to leg traps. Less chance to catch something other than a coyote. Also, coyotes will chew the leg off that is entangled to free themselves. They can't do that when you have them around the neck.

If they are coming up around your farmhouse, they are probably after your cat. We have lost cats to coyotes in the past. They get bolder and bolder as they go unmolested, showing up in sight of the house during the day and coming right up to the house at night. If you have dogs, a younger pup will come up and yip at the dog to try entice the dog to come out and chase it. It will lead the dog away from the house, where the rest of the pack is lying in wait.
