Common Poisonous Spider Found in North Carolina

In most cases, spiders that you see in and around your home are harmless. You may not love that they keep such close quarters with you, but they won’t actually bite humans. However, there are some exceptions. In North Carolina, there are two types of poisonous spiders that you should be aware of: the brown recluse and the black widow. Learn more about these common poisonous spiders and what you should do if you encounter them. 

Black Widow Spiders

Black widows have both a menacing name and distinct physical characteristics. Female black widow spiders are known for their black bodies and red hourglass marking on the underside of the abdomen. Male black widow spiders tend to be black or grey in color. They aren’t as easily identifiable and their bites aren’t as severe, but they can still deliver venom. 

In the wild, black widow spiders like to look for protected spaces. They will gravitate towards dense plant growth and find homes under rocks and logs. Once they enter homes, they also look for protected spaces, which tend to include electrical and other outdoor equipment boxes, crawlspaces, and dark corners. 

Like many species, black widow spiders build a web that is used to capture various insects. Once the insect is trapped, the spider will deliver a bite that is used to inject venom. When humans receive a bite, they may not experience any pain from the actual bite, but the venom will go to work on the nervous system. 

Symptoms of a black widow bite include blue and white discoloration at the site along with nausea, sweating tremors, increased white blood cells, and elevated blood pressure. It is important to see a doctor as soon as possible. They will be able to provide an antivenom serum and other treatments.

Brown Recluse Spider

Fortunately, the brown recluse spider is not commonly found in North Carolina. It is certainly present in the state, but it is relatively rare to encounter one. These spiders are also known for their unique markings. The spider is mostly brown in color but will have a fiddle-shaped marking near the head. Scientists also distinguish this species from similar-looking spiders by the fact that they have a total of six eyes that are split into three pairs.

Since the spiders are relatively small – they average a ¼ – ½ in size – it can be difficult for the average person to correctly identify a brown recluse. Unfortunately, a bite can also take 3-8 hours to appear. The first signs of a bite include swelling and tenderness. Eventually, a blister may appear. In the worst cases, a necrotic lesion, which is a deadening of the skin, will appear and require surgery. These symptoms should not be taken lightly.

Spiders are a common and essential part of the ecosystem, but in some cases, they can be harmful to humans. It is important to be able to identify venomous species.
