Tennessee, with its diverse landscapes ranging from mountains to forests to plains, boasts a rich variety of spider species. While most are harmless, understanding the different types can ease any anxieties and help you appreciate the crucial role they play in the ecosystem. This guide will explore some common and notable spiders found in the state, addressing frequently asked questions to provide a complete picture.
Common Spiders Found in Tennessee Homes and Gardens
Many spiders in Tennessee are quite common and easily identified. Here are a few examples:
-
American House Spider ( Parasteatoda tepidariorum): These are small, brown spiders often found in the corners of rooms, garages, and basements. They build messy, three-dimensional webs. While their bite is generally harmless to humans, causing only mild irritation, their webs can be a nuisance.
-
Orb Weavers ( Araneidae family): These spiders are known for their beautiful, circular webs often seen in gardens and around outdoor lights. Many different species fall under this family, varying in size and color. Most are harmless, but their webs can be surprisingly sticky!
-
Jumping Spiders ( Salticidae family): These are easily recognizable by their large, forward-facing eyes and their remarkable jumping ability. They're usually small and brightly colored. Jumping spiders are active hunters and don't typically build webs. They are generally harmless to humans.
-
Wolf Spiders ( Lycosidae family): These are larger, hairy spiders that are often found hunting on the ground. They don't build webs but chase down their prey. Their bite can be painful, similar to a bee sting, but rarely causes serious medical issues.
-
Black Widow Spiders ( Latrodectus mactans): This is arguably the most infamous spider in Tennessee, easily identified by the characteristic red hourglass marking on its abdomen. While their venom is neurotoxic and can be dangerous, requiring medical attention if bitten, their bites are relatively uncommon. They tend to prefer dark, undisturbed areas.
-
Brown Recluse Spiders ( Loxosceles reclusa): While less prevalent in Tennessee than some other spiders, brown recluse spiders are of concern due to their potentially harmful bite. They are identified by their violin-shaped marking on their cephalothorax (head and chest area) and prefer dark, secluded places.
What is the most dangerous spider in Tennessee?
The black widow spider is widely considered the most dangerous spider in Tennessee due to its potent neurotoxic venom. However, it's crucial to remember that bites are relatively rare, and fatalities are extremely uncommon, especially with prompt medical treatment. Proper identification is key, and it's always best to avoid handling any spider.
Are there poisonous spiders in Tennessee?

How to Identify Spiders in Tennessee
Accurate spider identification often requires detailed observation and possibly consulting with an entomologist or using a field guide with high-quality photographs. Consider taking pictures of the spider, noting its size, color, web type (if present), and location to assist in identification.
What to do if you get bitten by a spider in Tennessee?
If bitten by a spider, it’s crucial to stay calm. Wash the bite area thoroughly with soap and water. Apply a cold compress to reduce swelling. Monitor the bite for any adverse reactions such as increasing pain, swelling, fever, or nausea. Seek medical attention if necessary, particularly if you suspect a black widow or brown recluse bite.
