From Best Columbus Pest Control: “If you have seen spiders in or around your home and are wondering if they are dangerous to you, your children, or your pets, use the US Spider Identification Chart found below to help identify them. Just be careful. If you cannot trap or view the spider without getting bit, it is best to steer clear and let the professionals take care of any identification.”
There are some bad charts out there showing spiders listed as US but being from around the world. This chart was, however, pretty good and worth sharing. This is not an exclusive list as there are hundreds of spider types in the US; but it is a helpful guide. Most spiders are not harmful to humans, but know which ones to watch out for.
