Skunks can be discouraged from visiting by scattering a few mothballs around on the ground. They are repelled by the smell of camphor. Three to eight young are born blind and are weaned at six to seven weeks. Skunks are omnivorous, eating mice, eggs, insects, grubs, fruit, carrion, and shrews. Great horned owls are predators that commonly eat skunks.
Skunks find shelter under buildings or in ground burrows taken over from other animals.
Skunks are active year-round. I once lived in a house that had a family of skunks denning underneath. The smell got to be pretty strong after a while, but it was still tolerable. Eventually, they moved out on their own. E-mail me and tell me about it.
