I have a problem that I haven't seen in the 7 years since I built my house. This summer I started to notice very shallow tunnels under my lawn; you can feel them under foot. There all over the place. I see quite a few chipmunks in the yard. I have never seen moles. What do I do? I have a dog so I really don't want to leave poison out we he can get at it. What do you think it is and what do you suggest I do? Thank you in advance for your help. I haven't noticed any turf damage yet. My neighbor seems to think I should just leave it alone.
