Demystifying the Wolf Spider Bite: Facts, Symptoms, and Treatment Explained


Welcome to this comprehensive guide on the appearance of a Wolf Spider and, more importantly, what actions to take if you are bitten by one.

Spiders are creatures that often evoke fear and unease due to their unsettling appearance. Have you ever wondered what it would be like to be bitten by a spider? Trust us when we say it’s an experience you would want to avoid at all costs.

Wolf Spider bites can range from mild to potentially lethal, depending on the species. The Wolf Spider is a particular type of spider whose bite may not be deadly to humans, but it can still cause significant fatigue, discomfort, and itching.

If you have an allergic reaction to a Wolf Spider bites, you may experience prolonged pain and swelling, leaving you feeling uncomfortable in the affected area for an extended period.

To prevent a Wolf Spider bite, it’s important to familiarize yourself with their behaviour and survival mechanisms, enabling you to stay informed and recognize the circumstances in which a spider might bite.

Why Do Spiders Bite?

Wolf Spider bites

Spiders resort to biting as a defensive mechanism or to catch their prey. When a spider feels threatened, it may resort to biting as a means of self-protection.

However, not all spiders possess the instinct to attack and bite. Only a select few species bite when they perceive a danger or threat.

For example, species such as Wolf Spiders, Brown Recluse Spiders, Black Widow Spiders, Hobo Spiders, and Camel Spiders are more prone to biting if they feel endangered.

Furthermore, the majority of spiders pose no significant harm to humans, and only venomous species have the potential to cause severe reactions. They employ their venom to immobilize their prey, making it easier to capture and consume.

Additionally, their fangs are adapted for hunting insects and capturing them. Out of over 50,000 spider species, only a small number possess fangs and venom that can penetrate human skin.

Now that you understand the factors that can provoke a spider to bite, let’s delve into the characteristics of a wolf spider bite and the potential risks it presents to the human body.

What Does A Wolf Spider Bite Look Like?

A bite from a wolf spider typically results in two small puncture marks on the skin, indicating the penetration of their fangs. The skin may exhibit slight tearing and bear bite marks resembling fangs.

Furthermore, a wolf spider bite can manifest as a reddened, swollen, and painful area on the skin. It is possible for the bite to also cause itching and mild burning sensations. Some individuals may develop a blister or a minor wound at the bite site.

However, distinguishing whether you have been bitten by a wolf spider or another species can be challenging unless you are familiar with the appearance of a wolf spider.

Therefore, continue reading to gain knowledge about the physical characteristics and habitat of wolf spiders.

What Do Wolf Spiders Look Like?

Wolf Spiders possess coats that range in colour from brown to grey, featuring pale markings or stripes on their dorsal side. The specific colouration can vary depending on the geographical region they inhabit.

In terms of size, these spiders exhibit a range from half an inch to 2 inches (approximately 10 mm to 35 mm). What sets them apart is their distinctive arrangement of eight eyes, organized in three rows. This unique eye arrangement serves as a key identifying feature.

The third row consists of four minuscule eyes, the middle row contains two large eyes, and the top row has two medium-sized eyes. This characteristic distinguishes them easily from nursery web spiders.

To identify a spider as a wolf spider, one can utilize a flashlight. When light is directed at a wolf spider, its large eyes reflect the light to the source, creating a noticeable glow. This reflection is attributed to a retroreflective tissue known as tapetum lucidum, present in the top and middle rows of the eyes. The resulting eyeshine is a result of the light reflection, enabling easy identification.

With these distinguishing features, wolf spiders possess the third-best visual acuity among all spider species.

Confusion with Brown Recluse Spiders

However, it is common for people to mistake wolf spiders for brown recluse spiders due to their similar size and colouration. Nevertheless, the brown recluse spider is significantly more menacing as it possesses a venom that is far more potent than that of the wolf spider.

One way to distinguish between the two species is by examining the head shape. The brown recluse spider has a distinct head shape resembling a violin. Additionally, they typically have a brown hue with darker markings on the posterior section of their violin-shaped heads.

Now that you are familiar with their physical characteristics, it is important to know which areas to avoid to prevent wolf spider bites. So, let’s delve into the habitats where these creatures tend to reside.

Places Where You May Encounter A Wolf Spider

Wolf spiders can be found across the globe and inhabit a wide range of habitats. They are prevalent in many parts of North America, including the United States and Canada. Additionally, they can be found in South America, Europe, Asia, and Africa. In Australia, they are particularly common, and some species possess venom that can cause severe reactions.

Typically, wolf spiders are found in terrestrial environments such as fields, forests, and deserts. However, they can also be encountered in prairies, grasslands, and meadows. They are known to be adaptable and can be found residing in various areas within homes, such as basements, crawl spaces, and undisturbed corners.

Wolf spiders can climb smooth surfaces, and they are often observed near the ground and within vegetation. Gardens and rocky outcroppings are common locations to spot them.

Their adaptability enables them to thrive in diverse environments, ranging from deserts to forests, and from lowlands to mountains. They can also survive in urban areas and are frequently found in gardens, parks, and backyards.

Wolf spiders are nocturnal creatures, primarily active during the night. During the day, they seek shelter in burrows, under rocks, logs, or other debris.

Despite their fearsome reputation, the reality of a wolf spider bite is not as alarming. Without further delay, let’s explore the symptoms of a wolf spider bite and various methods of treatment.

Symptoms of A Wolf Spider Bite

It is crucial to understand that severe reactions to a wolf spider bite are uncommon, as the venom of these spiders is not considered toxic to humans. However, an individual may develop an allergic reaction to the spider’s venom.

Wolf spider bites can produce varying symptoms depending on the person and the amount of venom injected. Generally, these symptoms include pain, itchiness, a burning sensation, and redness. Systemic symptoms such as fever, nausea, muscle pain, and swollen lymph nodes may also occur. Occasionally, bites can cause mild headaches, localized pain, or swelling that may persist for a few days.

The most common symptoms of a wolf spider bite are as follows:


Due to their large size, wolf spider bites can be quite painful. The sizable fangs can tear the skin, potentially leading to infection and swelling of the lymph nodes. The duration of pain can vary from a few minutes to a few days, depending on the individual’s allergic response or immune system strength.


Swelling is a typical symptom of a wolf spider bite, as it often accompanies insect bites in general. It occurs due to the venom and the penetration of the spider’s large fangs, causing the skin to appear swollen.


A wolf spider bite may result in mild burning sensations, leading to intense itchiness in the affected area. However, the positive aspect is that this prickly sensation usually subsides within a few days as the skin begins to heal.


Wolf spider bites can cause redness around the affected area, often accompanied by a visible red bump on the skin. Rubbing or scratching the skin vigorously can intensify the redness, so it is important to avoid such actions.

For individuals allergic to venom, the symptoms of a wolf spider bite can be more severe. Immediate medical attention is necessary if the symptoms extend beyond the normal criteria mentioned above. Allergic reaction symptoms may include hives-like bumps, swelling around the mouth, unconsciousness or dizziness, an expanding red line from the bite indicating blood infection, tight muscles or cramping near the bite, headache, sweating, vomiting or nausea, fever, rash spreading outward from the bite causing itchiness, and uncontrollable shaking or weakness. If these symptoms occur, seeking medical attention is imperative.

However, it is important to note that some individuals may not feel the bite or experience any symptoms at all. This can make it difficult to determine if a bite has occurred. It is best to err on the side of caution by cleaning the affected area with soap and water and applying antiseptic to prevent infection.

Continue reading to learn about various methods of treating a wolf spider bite with mild or severe symptoms, either at home or with the assistance of a medical professional.

Treatment for a Wolf Spider Bite

 Treating a wolf spider bite involves following similar steps to those taken for any other insect bite. These measures include:

  1. Clean the bite area gently with warm water and soap.
  2. Cover the bite with a bandage to prevent infection.
  3. Apply an ice pack to reduce swelling around the bite.
  4. Avoid scratching the bite, as it significantly increases the risk of infection.

If the bite becomes very uncomfortable and itchy, it is advisable to consult a doctor for further treatment. In more severe cases, a medical professional may provide the following treatments:

  1. Prescribe stronger antihistamines to alleviate itching.
  2. Administer a tetanus booster shot for protection.
  3. Prescribe antibiotics to reduce or prevent infection.
  4. Recommend surgery as a last resort if the wound becomes deep and infected, and other treatments have been ineffective.


These are commonly used in the treatment of wolf spider bites. They help reduce swelling and itching by blocking the release of histamine, a chemical responsible for tissue swelling and itching. A quick-acting antihistamine, such as diphenhydramine (Benadryl), is often prescribed for wolf spider bites. It is important to note that antihistamines may cause drowsiness.
