10 North Carolina Poisonous Spiders To Avoid
The state of North Carolina, known for its rich biodiversity and varied landscapes, is home to a wide range of spider species. While most spiders are harmless to humans, there are several species found in North Carolina that are poisonous and can pose a threat to human health. Understanding which spiders to avoid and how to identify them is crucial for anyone living in or visiting the area. Here’s a comprehensive guide to 10 poisonous spiders in North Carolina, including how to identify them, their habitats, and what to do in case of a bite.
1. Black Widow Spider
The black widow spider is one of the most recognizable poisonous spiders in North Carolina. It has a shiny black body with a distinctive red hourglass shape on its abdomen. Black widow spiders are found throughout the state, often in dark, dry areas such as woodpiles, eaves, and other undisturbed spots. Their venom can cause severe pain, muscle cramps, and breathing difficulties.
2. Brown Recluse Spider
While less common in North Carolina than in some other parts of the country, the brown recluse spider is still a significant concern due to its dangerous venom. It has a distinctive violin-shaped mark on its body and is light to dark brown in color. Brown recluse spiders prefer dark, undisturbed areas and can be found in basements, attics, and closets. Their bites can lead to necrotic lesions, pain, and other systemic symptoms.
3. Brown Widow Spider
The brown widow spider, a relative of the black widow, has a brown or gray body with an orange or yellow hourglass figure on its abdomen. It is less common than the black widow but is still poisonous. Brown widow spiders are known for their neurotoxic venom, which can cause symptoms similar to those of the black widow but is generally considered less severe.
4. Wolf Spider
Wolf spiders are large and hairy, often mistaken for tarantulas. They are not typically poisonous to humans in the same way as black widows or brown recluse spiders, but their bites can be painful and may cause some swelling and redness. Wolf spiders are active hunters and can be found in a variety of habitats, including gardens, forests, and even inside homes.
5. Cellar Spider
Cellar spiders, also known as daddy long legs, are often confused with the brown recluse due to similar body shapes. However, cellar spiders are harmless and do not have venom that is toxic to humans. They are recognizable by their very long, thin legs and small body. Including them in this list serves as a reminder to accurately identify spiders before assuming they are poisonous.
6. Yellow Sac Spider
Yellow sac spiders are common household invaders and can deliver a painful bite. Their venom is not typically dangerous to humans but can cause minor symptoms. They are pale yellowish-green in color and have a distinctive sac-like web. Yellow sac spiders are often found in corners, around windows, and near doors.
7. Green Lynx Spider
The green lynx spider is recognizable by its bright green color. While its venom is not highly toxic to humans, it can still cause some pain and swelling at the bite site. Green lynx spiders are active hunters and do not use webs to catch prey, preferring to ambush insects.
8. Fishing Spider
Fishing spiders are large and have excellent eyesight. They are semi-aquatic and can be found near water bodies, where they catch fish and other aquatic prey. While they can bite, their venom is not typically harmful to humans, causing at most minor irritation.
9. Barn Spider
Barn spiders, also known as corn spiders, have a distinctive cross-like pattern on their abdomen. They are not poisonous but can still bite if threatened. Barn spiders are common in gardens and near outdoor structures, where they spin their characteristic wheel-shaped webs.
10. Trapdoor Spider
Trapdoor spiders are recognizable by the trapdoor they create to cover their burrows. They are generally harmless to humans but can deliver a painful bite if provoked. Trapdoor spiders are ground dwellers and can be found in lawns, gardens, and under leaf litter.
Identifying Poisonous Spiders
Identifying spiders accurately is crucial to avoid unnecessary panic and to take appropriate action in case of a bite. Here are some tips:
- Research Local Spiders: Familiarize yourself with the spiders found in your area.
- Observe Body Shape and Color: Different spiders have distinctive body shapes and colors that can help in identification.
- Look for Distinctive Marks: Spiders like the black widow and brown recluse have distinctive marks that can aid in identification.
- Consult Experts: If you’re unsure about the identity of a spider, consult with a local pest control service or an entomologist.
Prevention and First Aid
Preventing spider bites involves reducing the presence of spiders in your home and being cautious in areas where spiders are common. Here are some prevention and first aid tips:
- Seal Entry Points: Spiders can enter homes through tiny cracks and crevices. Sealing these can help reduce the number of spiders inside.
- Keep a Clean Home: Regular cleaning can reduce the presence of insects that spiders prey on, thereby reducing the attractiveness of your home to spiders.
- Wear Protective Clothing: When working in areas where poisonous spiders are common, wear long sleeves, gloves, and closed shoes.
- First Aid for Bites: For non-poisonous spider bites, apply a cold compress to reduce swelling. For bites from poisonous spiders like the black widow or brown recluse, seek medical attention immediately.

By being aware of their habitats, recognizing their physical characteristics, and taking preventive measures, individuals can minimize their risk of spider bites.
