Alabama has striped and spotted skunks, and the state’s striped-skunk profile describes the animal as normally active at night and using underground burrows for daytime shelter. Seeing a skunk moving across the yard is therefore not the same as confirming that it has established a den under your home.
The state’s nuisance guidance identifies decks, porches, foundation openings, and other sheltered locations as possible den sites. The practical inspection emphasis is at ground level: where the opening leads, what structure it serves, and how the perimeter can be protected once the animals are accounted for.
Family status also matters. The striped-skunk profile describes late-winter to early-spring mating and young that are born blind and helpless, which is why removal planning should include the possibility of dependent young rather than rely only on the adult you have seen.
For the homeowner, the next step is not to test the den yourself. Describe the observations you already have and ask the technician to explain the species assessment, den access, and proposed barrier before any opening is closed.
