Identifying a Wolf Spider Bite
Wolf spiders are common arachnids found throughout the United States, known for their unique hunting habits and appearance. While spider bites are relatively rare, wolf spiders will occasionally bite humans if threatened or unintentionally contacted. Here is what to look for to identify a wolf spider bite and distinguish it from other insect bites or skin conditions.
Appearance of a Wolf Spider Bite
A wolf spider bite on day 1 will likely result in the following symptoms:
- Mild pain similar to a bee sting at the bite site
- Reddening of the skin around the bite
- Some minor swelling around the bite area
- Small puncture wound where fangs entered the skin
- Itchy skin surrounding the bite
Wolf spider bites are usually not very serious. They may bleed slightly when first bite happens due to the fangs piercing the skin. However, the venom from a wolf spider is designed to take down small invertebrate prey and is not medically significant to humans.
Difference From Other Insect Bites
On day 1, a wolf spider bite can be hard to visually distinguish from other insect bites, including:
- Mosquitoes - Cause red, swollen, itchy bumps.
- Fleas - Result in small clustered red bumps or welts.
- Bed bugs - Lead to clusters of swollen, itchy red welts.
- Bees/Wasps - Cause a painful stinging sensation and swelling.
However, a wolf spider bite may be identified by two small fang puncture marks in the center of the bite, whereas other insect bites typically do not have any puncture wound.
Difference From Skin Conditions
On the first day, a wolf spider bite could also be mistaken for other non-insect related skin reactions like:
- Allergic reaction - Causes hives or itchy red welts on skin.
- Contact dermatitis - Leads to an itchy rash where a substance touched skin.
- Pimple or cyst - Results in a tender, swollen bump on skin.
However, these conditions will not have a visible animal bite like the small fang marks that can occur with a wolf spider. Monitoring for worsening symptoms can also help distinguish a bite versus other skin affliction.
Treating a Wolf Spider Bite
Spider bites usually do not require medical intervention. Here is how to treat a wolf spider bite at home:
Clean the Bite Site
Use soap and water to gently cleanse the bite area. This removes any residual venom and decreases risk of infection.
Apply a Cold Compress
Wrap an ice pack or cold cloth over the spider bite to reduce swelling, inflammation and itchiness. Do this for 10-15 minutes a few times per day.
Elevate the Area
If possible based on bite location, keep the arm or leg with the spider bite elevated. This discourages swelling and fluid buildup.
Take Antihistamines
Over-the-counter antihistamines like diphenhydramine can alleviate itching. Follow dosage on the medication packaging.
Use Hydrocortisone Cream
Apply a topical hydrocortisone cream containing 1% solution to the bite to reduce redness and swelling. Reapply as label directs.
Avoid Scratching or Popping
As difficult as it may be, try not to scratch or pop the spider bite. This can worsen irritation and also introduces bacteria into the wound.
When to Seek Medical Treatment
In very rare cases, a wolf spider bite may require medical treatment if the following warning signs appear:
- Significant swelling moves up the arm or leg from the bite site.
- The redness and pain expand far beyond initial bite.
- Flu-like symptoms like fever, chills, fatigue or headache develop.
- Pus, widened red streaks or swollen lymph nodes around the bite.
- Muscle cramps, tremors or numbness around the bite location.
Seek prompt medical care if experiencing any severe side effects after a suspected wolf spider bite to receive appropriate treatment. Very dangerous spider bites like those from black widows or brown recluses are highly uncommon.
Allergic Reaction to Spider Venom
On very rare occasions, a person may have a severe allergic reaction to components in wolf spider venom. Signs of a serious allergic reaction include:
- Shortness of breath or tightness in the throat.
- Swelling of the lips, eyes or face.
- Dizziness, chest pain or rapid heartbeat.
- Nausea, abdominal cramping or vomiting.
- A drastic drop in blood pressure indicated by feeling faint.
If experiencing these wolf spider bite symptoms, call 911 or seek emergency medical care immediately. Anaphylaxis can be life-threatening if not treated promptly with epinephrine.
Antibiotics for Infection
Occasionally a spider bite can develop a secondary bacterial skin infection evident by:
- Increasing redness, pain and swelling around the bite.
- Pus or foul-smelling discharge from the bite wound.
- Enlarged red streaks extending from the bite.
- Fever, nausea and flu-like symptoms.
Your doctor may prescribe oral antibiotics or antibiotic creams to clear up the spider bite infection.
Wolf Spider Bite Pictures
To help identify wolf spider bites, here are some photos of how they may appear:
Day 1 Wolf Spider Bite
On the first day, a wolf spider bite results in a slightly swollen, red and painful welt with two small central puncture marks evident:

An infected wolf spider bite will have pus, enlarged redness and potentially red streaks extending from the wound 2-3 days after the bite occurs:

Once treated, a wolf spider bite improves in appearance over 5-7 days - the swelling, redness and pain subside while the puncture marks slowly fade:

Wolf spiders play an important role controlling insect populations but will bite humans if threatened or accidentally touched. Here are some tips to avoid wolf spider bites:
- Carefully inspect or shake out clothing, shoes or towels left on floors before use.
- Wear gloves and long sleeves when cleaning garages or basements where spiders dwell.
- Seal cracks around doors and windows to deter spiders from entering home.
- Install insect screens on windows and vents to keep spiders out.
- Remove trash, clutter and debris where spiders may hide and nest.
While painful, the vast majority of wolf spider bites do not cause serious effects and home treatment is often sufficient for complete recovery. Seek medical attention for any concerning side effects or signs of infection after a suspected wolf spider bite.
