Cellar Spider Bite
Almost all spiders are venom producers. However, of the many known spider species, very few are capable of harming humans. To date, no known cellar spider bites have led to illness.
Despite their innocuous nature, cellar spider populations can prove troublesome to homeowners. Because they choose to live in close proximity to other cellar spiders, they may begin to plague an infested home.
