As far as "shrew damage" I don't encounter anything but I do encounter "the presence of shrews" and their dime sized holes in many lawns with vole activity. I catch shrews on just about every vole job. I usually get calls when people are doing their Spring cleanups and working in their flower beds or changing the mulch out. I don't target these but I do provide info on my website to help a prospect identify them. As stated on my site "Trapping and a bit of habitat modification can generally rid your lawn of these pests if they ever reach an unacceptable level. This includes removing old logs, brush, leaves, boards, rocks and other items from shady, damp areas that insects are drawn to and keeping your lawn cut short in areas of high activity." I would never try to sell a shrew job but I would do the cleanup for the right price as some folks are afraid of what they may encounter (generally a snake).
