I think I've got.....Toads?
I noticed a 13 lined ground squirrel in the orchard about a month ago. I thought it was kind of neat, until I noticed a few holes going down right into the softer dirt where I just planted the trees. I applied some treated wheat to get rid of them and then I filled and packed the holes back in.
Today I was back out and saw more holes, but no ground squirrels. I went out tonight with the pellet gun and the only thing I see around the holes are toads.
My orchard is out in what used to be virgin shortgrass pasture and the toads are native. Normally they aren't out when it is dry, but apparently they have found nice moist spots every 12-15 ft where I have trees.
Maybe I shouldn't worry because they wont be chewing on roots and they will be eating bugs, but I worry that they will aerate the root zone too much. What do you guys think about it?
Im not sure what a person could do to keep them from digging around the trees, maybe urea?
