So I have about 25-30 of these critter holes all over the grass on my Sleepers Island property. I set up a baited "Have a Heart" trap for about a week and caught nothing. I've never seen a chipmunk on the property but there are a lot of red squirrels. I have yet to see anything go in or out of the holes. In 5 years being out on the island this is the first summer I've seen holes like this.

If I run water down the holes with the garden hose it will run on and on and not fill up. I've put moth balls down the holes. I see no mole tracks either.

I'm stumped! Neighbors are stumped too.

Thanks in advance for any info
