Although not common in Baltimore County, skunks do occasionally show up. Like groundhogs, they will excavate nest cavities underneath sheds, porches, or building foundations. Skunks have a habit of digging up yards in search of grubs. Skunks are the biggest threat to dogs. They can be trapped in much the way raccoons are trapped; removing the trapped skunk from your yard without getting sprayed is our problem, not yours.
