The world of spiders is vast and diverse, with over 48,000 known species. While most spiders are harmless to humans, a select few can deliver a painful or even dangerous bite. If you're curious about what a spider bite looks like, read on for an in-depth guide.
Spider bites can vary in appearance depending on the type of spider and the severity of the bite. In general, spider bites often appear as raised, red bumps or welts. The area around the bite may be swollen, itchy, or painful. In some cases, spider bites can also cause more severe symptoms, such as nausea, vomiting, or muscle cramps. If you experience any of these symptoms after being bitten by a spider, it's important to seek medical attention immediately.
Now that we have a basic understanding of what a spider bite looks like, let's take a closer look at some of the most common types of spider bites and their associated symptoms.

Spider bites can vary in appearance, but here are 10 important points to keep in mind:
- Raised, red bump or welt
- Swelling
- Itching
- Pain
- Nausea
- Vomiting
- Muscle cramps
- Headache
- Fever
- Chills
If you experience any of these symptoms after being bitten by a spider, it's important to seek medical attention immediately.
Raised, red bump or welt
One of the most common signs of a spider bite is a raised, red bump or welt at the site of the bite. This bump or welt is usually firm to the touch and may be surrounded by a red halo. It can range in size from a small pimple to a large, swollen area.
The appearance of the bump or welt can vary depending on the type of spider that bit you. For example, bites from black widow spiders typically cause a small, red bump that is surrounded by a white halo. On the other hand, bites from brown recluse spiders often cause a larger, more painful bump or welt that can develop a blister or ulcer.
In addition to the raised, red bump or welt, you may also experience other symptoms at the site of the bite, such as:
- Swelling
- Itching
- Pain
- Warmth
- Tenderness
If you experience any of these symptoms after being bitten by a spider, it's important to clean the wound and apply a cold compress to help reduce swelling and pain. You should also monitor the bite for signs of infection, such as increased redness, swelling, or drainage. If you're concerned about the bite, it's always best to seek medical attention.
It's important to note that not all spider bites will cause a raised, red bump or welt. Some spider bites may only cause a small, itchy mark, while others may not cause any visible symptoms at all. If you're not sure if you've been bitten by a spider, it's always best to err on the side of caution and seek medical attention.
Swelling
Swelling is another common symptom of a spider bite. The area around the bite may swell up, sometimes to a significant degree. Swelling can occur within minutes or hours of the bite and may last for several days or even weeks.
The amount of swelling you experience will depend on the type of spider that bit you and the severity of the bite. For example, bites from black widow spiders typically cause mild to moderate swelling, while bites from brown recluse spiders can cause severe swelling that may extend up the affected limb.
Swelling can be uncomfortable and may make it difficult to move the affected area. It can also be a sign of infection, so it's important to monitor the bite closely. If the swelling is severe, painful, or accompanied by other symptoms such as redness, warmth, or drainage, it's important to seek medical attention.
To help reduce swelling, you can try the following:
- Apply a cold compress to the affected area.
- Elevate the affected limb above your heart.
- Take over-the-counter pain relievers, such as ibuprofen or acetaminophen.
If the swelling is severe or doesn't improve with home treatment, it's important to see a doctor.

Some spider bites may only cause a small, itchy mark, while others may not cause any visible symptoms at all. If you're not sure if you've been bitten by a spider, it's always best to err on the side of caution and seek medical attention.
Itching
Itching is another common symptom of a spider bite. The bite area may feel itchy, irritated, or burning. The itching can be mild or severe, and it may last for several days or even weeks.
The itching caused by a spider bite is often due to the body's reaction to the spider's venom. When a spider bites, it injects venom into the skin. This venom can cause a variety of symptoms, including itching, swelling, pain, and redness.
Itching can be a nuisance, but it's important to avoid scratching the bite area. Scratching can irritate the skin and make the itching worse. It can also increase the risk of infection.
To help relieve itching, you can try the following:
- Apply a cold compress to the affected area.
- Take over-the-counter antihistamines, such as diphenhydramine or loratadine.
- Use calamine lotion or hydrocortisone cream to help soothe the skin.
If the itching is severe or doesn't improve with home treatment, it's important to see a doctor.
