Skunks smell sounds terrible. There are some things in life that I can live without. Sounds like skunk smell is one of those things. My only contact with a skunk for my entire life will be watching an amorous Pepe le Pew trying to romance a kitteh cat in a cartoon. Mwah mwah mwah.............
Would it make any difference if you were able to hose the area down? Do skunks hibernate? Maybe I should google these little dudes. Sounds like Bambi lives on your property.
Hope your headaches ease up very soon.
