I live in a rural area next to a small strip of woods/wild growth. I have a fenced-in yard, approx 60'x100'. Inside the fence, I can see 12-14 huge mounds of dirt. The 3-4 largest measure l2"x36"x5" high. I see no entrance hole. If I shovel the pile off level, it's usually right back overnight. I've lived here 15 yrs and we've always contended with moles but I've never seen anything like this. Help!
