Skunks have a few habits that may be detrimental to humans, but the most annoying habit may well be their pension for digging under porches and buildings. They seem to have a knack for finding openings in poured wall foundations and working from there. The fear is of course that they will spray under a building leaving a lasting, offensive scent.
On a serious note, skunks are the primary carriers of rabies in most parts of North America. Many experts recommend staying far away from overly aggressive skunks and even reporting such animals to your local animal control agency. This includes observing them roaming around during the daytime on a regular basis.
Skunks aren’t all bad, though. They eat many pests and help to control insect populations as well as rodents that can cause crop damage.
