My mom took a few pictures of her yard. This seems to happen every year for the last 5 years or so. Are these vole trails? And what are the possibly ways to rid them? She tried traps from an exterminator but it doesn't seem to do a lot of good. Trying to possibly find other alternatives if this is the case. Thank you!

It could be voles. It is impossible to say for sure if you never see the animal. Here is a link about voles that you can look at and compare. It also offers tips for dealing with them. http://www.extension.umn.edu/garden/yard-garden/wildlife/voles-in-the-landscape/ .
