Are brown widow spiders dangerous = Strong and painful, but not as bad as a Redback’s bite. Redback venom is slightly more toxic than Brown Widow venom. They appear to be more susceptible to human interactions in terms of bites because they select locations that are more exposed than those chosen by black widows.
