But you should use gloves and just get in the habit of when you touch your traps make sure you are wearing gloves. The question of rust came up also on a coyote trapping question. Know that a coyote range is up to 50 miles. When setting coyote traps if a little rust appears on the trap use fox or coyote urine sprayed over the cover trap. This will show the next coyote another coyote was all ready been there and it is safe to walk up.
Coons have no problem raiding chicken coops.
They raid garbage cans and do not fear human scent the same way as a fox or coyote does. I think most of you will be trapping with conibears the first few years, going after muskrats, raccoons, beavers, and easier animals at first. Human scent is not that much of a concern, but having a trap well blended into the environment is a concern. Like I said, know what your are trapping, don 't wear the same boots to the gas station when you fuel up as do on the trapline. There is a rule that the old deer hunters use around here.
