less:Chipmunks:Holes tend to be cleanly dug and silver dollar sized. Note the shiny quarter to the left of the hole. Chipmunks are easily seen during the day. Photo by Stephen M. Vantassel.Crayfish:Crawfish can burrow 2 inch wide holes into the lawn. Lawns must be near water. Typically, there is a mud tower. 13-Lined Ground Squirrel:Very clean outside of hole. There may be another hole of similar size within 20 feet. They are easily seen on warm, sunny days. Look for grooves in the grass where they travel between holes. Kangaroo Rats:Den entrance is 2-3 inches wide and 3-4 inches long. They prefer sandy, dry soil. Populations can get quite high, >30 per acre.Rats, Norway:Holes tend to be 2-3 inches wide and smooth from repeated use. Rats are secretive and rarely seen during the day. If you see them during daylight hours, it means you have a lot of rats on the premises. Drawing of their burrow system can be seen below. Photo at right shows a Norwary rat hole. Note the 6" ruler above.Skunks:Skunks will dig specific and individual holes in their quest for grubs and lawn insects. They will be systematic, moving from section to section each night.Voles:The Pine Vole has dime sized holes, often around the roots of plants. Voles are primarily nocturnal. 4951

I found that there is a tunnel under a flower bed with a hole on each end. The hole is about the size of a golf ball.  I thought it might be frogs or snakes.  Ideas? 4951

@lola: Moles! 4951

@buffaloglenn: Hate moles. They do a lot of damage. My dog has killed a few of them. I have tried traps, poison worms. Hit or miss. I know the poison worms work but with dogs limited to the front yard. 4951

@mayorofnothing: Never thought  I would hear those words combined with Ebola lmao 4951

@midnightblue: The guys have a few trail cams at the hunting camp in Louisiana..maybe they'd bring one home for a little bit for me..
Then again, they might miss a big buck strolling by one of the stands! Oh, no! Won't matter they can't kill out of season, anyway! 4951

@midnightblue: Awesome! I'm thinking it's the 13-lined ground squirrel..that's just what the holes look like.. Now, let's talk remedies. Had a neighbor "humanely" exterminate a mole from her yard (i.e. Drive it out of her yard so it becomes someone else's problem, in that case, mine!)If they were digging up their stash..would that mean it's a one time excavation? Or at least til next Spring? Of course if that's the case they'll have to bury next-year's stash this fall but at least the holes would be covered right back up..Aside from going all Carl from Caddyshack, trying to kill the squirrels like he tried to kill the golfers..I mean, gofers..what do ya'll suggest? 4951

@mayorofnothing: No...you go get a new one on sale so it can go to LA after yard surveillance is done..Looks like a mole problem. Crawfish won't always have the mounds, but you can go out there at night and shine the holes to see them a lot of times.

My neighbor told me the hole in the ground at my house is dirt wasps or dirt hornets. He had one in his flower bed and he was pulling weeds and they flew out of the hole and chased him down the street. He said there was about 100 of them. He's going to pour gas down the hole in my yard , he said that should kill them. 4951

You will know it's moles with raised trails of earth all over the yard. They don't dig that deep unless it's their burrow then they go deep, probably a couple of feet. My dogs are probably the best defense. They will dig them up and kill them but it's a balance between keeping the dog door open at night and them barking at 3am and the neighbors wanting me dead. I use the poison worms for the front (gumby worms Telprid or something) and let dogs out a few  nights a month. Never really stop them but it keeps them under control. When I see them dead in the yard I had a good day.    4951
