For a mild, localized suspected spider bite, wash the area with mild soap and water, apply a cloth-wrapped cool pack for about 15 minutes each hour, elevate the area, and use label-directed over-the-counter pain or itch relief. Most spider bites cause only minor injury, but rapidly worsening symptoms, spreading redness, discoloration, severe pain or a growing wound need urgent medical assessment.
This guidance is for people. It does not establish treatment or medication doses for dogs, cats or other pets; contact a veterinarian promptly if an animal may have been bitten.
What to do immediately
- Clean the site. Wash gently with mild soap and water, then pat dry.
- Cool the area. Hold a cool, damp cloth or a cold pack wrapped in cloth against the skin for roughly 15 minutes each hour. Poison Control gives a 10–20 minute range. Never put ice directly on skin.
- Elevate when practical. Raising the affected arm or leg can help limit swelling.
- Relieve pain or itching. Use an over-the-counter pain reliever exactly as its label directs. For itch, an oral antihistamine, calamine lotion or low-strength hydrocortisone may help. Check age, pregnancy, medical-condition and medication warnings with a pharmacist or clinician.
- Protect and observe. A superficial, cleaned wound may receive over-the-counter antibiotic ointment as directed. Do not squeeze, cut, burn or repeatedly irritate the area.
- Check tetanus protection. A clinician may recommend a booster based on the wound and your immunization history.
How to tell whether home observation is reasonable
A mild local reaction generally stays limited to the bite area and does not progressively worsen. Keep a written note or photograph of its size and appearance so you can identify change. Arrange medical advice if the wound opens or drains, redness or pain keeps increasing, or fever or other whole-body symptoms develop.

Why appearance alone cannot diagnose a spider bite
A sore blamed on a spider may instead be caused by another insect, a bacterial infection, a burn or another skin condition. A photograph or safely retained specimen can help a clinician, but never handle a suspected dangerous spider. Do not delay care while trying to identify it from a picture.

Black widow and brown recluse patterns
| Feature | Black widow pattern | Brown recluse pattern |
|---|---|---|
| Typical progression | Pain and swelling can spread beyond the bite; systemic symptoms may develop. | Pain may increase during the first eight hours; the wound can progress over time. |
| Other symptoms | Severe abdominal pain or cramping, nausea, vomiting, tremors and sweating. | Fever, chills, body aches and blistering may occur. |
| Skin changes | Local findings may be less dramatic than the muscle or whole-body symptoms. | A pale centre may become dark blue or purple with a red ring; the sore can enlarge, tissue can die and a scar may remain. |
| Response | Prompt medical assessment; severe cases may require hospital treatment and sometimes intravenous antivenom. | Prompt medical evaluation because tissue injury can worsen. |
How long healing takes
Mayo Clinic says most spider bites heal in about a week. Recluse bites can take longer and may scar, so that estimate is not a promise for every wound. A lesion that is worsening rather than gradually settling should be assessed, regardless of how many days have passed.
