Call a critter wrangler
No food source, no coon. Squirrels are yard rats. They look for food, hide food and tear the living crap out of things. I’d bet squirrel. The only reason a coon would be there is it found a home. Possums love cat food. If your goning to trap a possum or coon use cat food. Trap squirrels with black oil sunflower seeds.
