Will skunks eat peanut butter laced with hot sauce or something else
to keep them out of my garden??

I've made oatmeal with hot peppers and fed it to squirrels.Most
commercial pest controls are made with chili peppers and mustard.I
somehow doubt if they have a lasting effect.

We had a skunk under the house and I caught it in a homemade live
trap. I released it in town.

Mothballs, naphthalene crystals, or ammonia soaked rags may be used to
temporarily discourage skunks from using a burrow or to discourage use
of a particular area before someone can close off the entrance.
Caution: when using these compounds, avoid contact with eyes, do not
inhale fumes, and wash hands after use. Bee keepers will find the best
method of keeping skunks away from their hives is to place the hives
on one metre high platforms. Alternatively, an electric fence placed
12.5 cm above the ground will keep skunks out.
