What's that awful smell?

If your not from an area where this "smell" is familiar, you will ask this question. Unfortunately, we in the Shenandoah Valley, know exactly what that is! It is a SKUNK! My house smelled like a cross between wet dog and skunk. We noticed this 2 nights ago  and also discovered a large hole going under the porch.
After doing some research I discovered that skunks choose a home where they have a good food supply and water source. We recently discovered that we have voles. Skunks eat voles. So, we must eliminate the food source. Also Skunks bear young from the end of April-first of June. It depends on the age of the mother. We need to decide what strategy to use to rid our home of this pesky critter without getting sprayed!
