I may have got a little tunnel vision, but over the past two years, I haven't been trapping because I haven't been able to dedicate time in the mornings to checking traps daily, due to work.

Is there any reason, from a humane or other standpoint I can't just check them in the afternoon/evening?

It appears the coyodels have repopulated the area and these appear to be educated from calling efforts

I don't think NC has a law that they have to be checked every morning, but may have a requirement to check them daily.
