In this article, we will explore everything you need to know about orb weaver spiders and their potential danger.

The Basics

Orb weaver spiders belong to the Araneidae family and are known for their spinning of circular webs that are highly organized. Their webs also often have a central part where the spider resides. These spiders can be found living all over the world, from the tropics to the temperate regions. In the United States, they are commonly found in gardens, meadows, and forests, where they spend the majority of their lives waiting for prey to stumble into their webs.


Identification of an orb weaver spider can be difficult, as there are over 4000 species of orb weaver spiders at present. These spiders generally have round bodies and a pattern on their abdomen, which can be distinct for each species. Their coloration can vary from black, brown, yellowish, to even green or fluorescent hues.

Physical Characteristics

  • Size: Typically, orb weaver spiders are small to medium-sized, ranging from a few millimeters to about 30mm in length.
  • Coloration: These spiders come in a range of colors depending on the species, with some having distinct patterns and coloration on their abdomen.
  • Web: Orb weaver spiders spin webs that have a distinctive circular shape with radiating strands that are often sticky.

Are They Dangerous?

While orb weaver spiders may look daunting because of their size and appearance, they are not generally considered to be dangerous to humans. These spiders are not aggressive and rarely bite unless provoked or handled roughly. In most cases, orb weaver spider bites are simple and only produce mild local reactions, such as mild pain, swelling, and redness. However, as with all spider bites, it is essential to keep an eye on the bitten area for any signs of infection or adverse reactions.

Spider Bites: What You Need to Know

If you believe you have been bitten by an orb weaver spider, it is crucial to take the following steps:

  • Clean the bite site with soap and water
  • Apply a cool compress to the area to reduce pain and swelling
  • If symptoms persist, seek medical attention


The best way to avoid being bitten by an orb weaver spider is to avoid disturbing their webs or their environment. Wearing long sleeves, pants, and gloves when working or spending time in areas where orb weaver spiders are prevalent can also help to prevent bites. However, it is crucial to remember that these spiders are generally harmless and not aggressive towards humans.

How to Deal with an Orb Weaver Spider

If you encounter an orb weaver spider, the best course of action is simply to leave them alone. These spiders are essential parts of their ecosystem, and they play a crucial role in controlling insect populations. Instead of trying to kill or harm these spiders, take the time to appreciate their beauty and observe them from a safe distance.


In conclusion, orb weaver spiders are not considered to be dangerous to humans. While their appearance may be intimidating to some, it is important to remember that they are generally not aggressive, and bites are rare. Instead, appreciate these beautiful creatures for the essential role they play in the natural world.


What do orb weaver spider bites look like?

Orb weaver spider bites typically produce mild local reactions, such as redness, swelling, and pain, that may last several hours or days. In most cases, these symptoms will subside without any medical intervention. However, if you experience more severe symptoms, such as nausea, vomiting, or difficulty breathing, seek medical attention immediately.

What is the difference between an orb weaver spider and a black widow spider?

While both orb weaver spiders and black widow spiders belong to the Araneidae family, they have distinct differences. Black widow spiders are typically smaller than orb weaver spiders and have a distinctive red hourglass-shaped marking on their abdomen. Black widow spider bites can also be more dangerous than those of orb weaver spiders, as black widow venom is stronger and produces more severe symptoms.

Do orb weaver spiders bite humans?

Orb weaver spiders are not typically aggressive towards humans and only bite if provoked, stepped on, or handled roughly. In most cases, the bites produced by these spiders are mild and cause only local reactions. However, it is still essential to keep an eye on the bite site and seek medical attention if symptoms persist or worsen.

What is the lifespan of an orb weaver spider?

The lifespan of an orb weaver spider can vary depending on the species. Some species, such as the garden spider, can live up to a year or more, while others have shorter lifespans. Females typically live longer than males.
