Due to North Carolina’s warm temperatures, spiders thrive in North Carolina and it is common to encounter spiders during every season. You might be surprised to learn that despite there being over 1,500 species of spiders in North Carolina, only 4 are dangerous.  To help you recognize these dangerous pests, Eco Advantage is explaining what to look for.


It is important to understand what makes spiders dangerous; they are venomous. This means they actively inject or attack prey with a toxic substance. This differs from poison,  as poisonous is passive and venomous is active.  With poison — a person has to come in contact with a poisonous substance in order to have an adverse reaction. Certain species of spiders, snakes, and wasps are considered venomous.


The black widow spider is probably the easiest spider to identify in North Carolina.

This spider is easy to identify by the following characteristics — shiny black color, red hourglass shaped marking on the mid-section, and round shaped body. Black widows tend to hide in a protected area, so most often you can find them in wood piles, hidden in crawl spaces, under rocks, or in damp, dark areas if they are inside.

Outside of North Carolina, the black widow is the most dangerous spider in North America.  The venom from a black widow is a neurotoxin  which means it affects the nervous system.  If you suspect you have been bitten, it is imperative to receive medical treatment immediately.

Symptoms of a black widow bite include:

  • Swelling, pain, and redness around the affected area
  • Blue-red spot surrounded by white area
  • Headache
  • Fever and chills
  • Nausea and vomiting
  • Muscle cramps and spasms near the bite, spreading and worsening over 6-12 hours
  • Sweating


Brown recluse spiders are not as common as people think; however they are found in North Carolina. The brown recluse can be identified by these characteristics — small body with very long legs and light to dark brown coloring.

Similar to black widows, they tend to hide in wood piles, crawlspaces, under rocks; in homes they can be found in dark areas that are typically undisturbed.

Brown recluse spiders are another dangerous, venomous spider.  A brown recluse bite requires quick medical treatment as the tissue around the bite can die quickly and have serious complications.

Symptoms of a brown recluse bite include:

  • Pain
  • Tissue decay at the site of the bite that turns purple in the center
  • Joint pain  Fatigue and lethargy
  • Nausea
  • Fever and chills


Due to its similar appearance to the black widow, this spider has been named false widow.  This spider can be identified by its shiny black body with large, rounded abdomens and thin legs; it differs from the black widow as they are missing the red hourglass mark.

False widows are more often found inside the home in less-traffic dark areas such as — basements, closets, and attics.

A false widow spider bite is not nearly as severe as a black widow’s bite; however, medical attention is still important as the bite can get infected and can have side effects.

Symptoms of a false widow bite include:

  • Pain and swelling at bite
  • Fever and chills
  • Lethargy
  • Nausea
  • Headache
  • Muscle aches


Yellow sac spiders are the most common cause of spider bites in North America and are found often in North Carolina.  They are easily identified by their small yellow or cream-colored bodies and dark brown coloring around their head.

These spiders are most common outside but when the weather gets cooler they make their way into homes. 

While the yellow sac spider is venomous, their bites do not generally cause severe reactions.  However some people are more sensitive to their venom and can develop some serious symptoms.

Symptoms of a yellow sac bite include:

  • Rash
  • Fever
  • Muscle cramps
  • Nausea
  • Ulceration around the bite
