South Carolina is home to six different species of venomous spiders. These include the brown recluse, black widow, yellow sac spider, southern black widow, northern black widow, and the red widow spider.

It is important to be cautious and aware of your surroundings when out in nature to avoid encountering these potentially dangerous spiders.
How many poisonous spiders are there in South Carolina?
There are two species of potentially dangerous spiders in South Carolina: the black widow spider and the brown recluse spider. Both spiders have venom that can be harmful to humans, but bites are rare and typically not life-threatening with prompt medical treatment.
How can I distinguish between a poisonous spider and a non-poisonous spider in South Carolina?
There are several ways to distinguish between a poisonous spider and a non-poisonous spider in South Carolina:
- Look at the color and markings: Poisonous spiders such as the black widow and brown recluse have distinct markings that can help identify them. Black widows have a shiny black body with a red hourglass shape on the underside, while brown recluses have a violin-shaped marking on their back.
- Check the size and shape of the body: In general, poisonous spiders have a more compact and robust body shape compared to non-poisonous spiders. Black widows are typically small to medium-sized spiders, while brown recluses are larger and have a more elongated body shape.
- Examine the eyes: Spiders have multiple eyes, with most species having eight eyes arranged in two rows of four. However, black widows have only six eyes arranged in two rows of three, which can be a distinguishing feature.
- Look at the web: Some poisonous spiders, like black widows, build irregular and messy webs, while non-poisonous spiders create more symmetrical and organized webs.
- Behavioral cues: Poisonous spiders are generally more aggressive and will bite if threatened, while non-poisonous spiders are more likely to retreat or flee when disturbed.
If you are unsure about the identity of a spider, it is best to avoid contact and seek the help of a professional pest control expert or entomologist for proper identification.
