What to Do If You’re Bitten by a Spider

Most spiders are harmless and prefer to stay out of sight. But every so often, a spider encounter leads to something less pleasant — a bite.

While the majority of spider bites cause only mild symptoms, some can lead to more serious reactions depending on the spider species and your body’s response. Knowing what to look for — and what to do next — can help you stay calm and take the right action.

Here’s everything homeowners should know about spider bites, including when to treat at home, when to see a doctor, and how to reduce your risk of bites in the future.

First Things First: Not All Bites Are Spider Bites

Many insect bites — from ants, mosquitoes, and even fleas — can mimic spider bites. Often, people assume a mystery bump is from a spider simply because they didn’t see what bit them. The truth is, unless you actually see the spider bite you, it’s hard to be certain.

That said, here are some common signs that could indicate a spider bite:

• Redness and localized swelling

• Mild pain or itching at the site

• A small puncture mark or blister

• A slow-developing sore or ulcer in more serious cases

If you live in an area where venomous spiders like brown recluses or black widows are present, it’s wise to err on the side of caution.

Step-by-Step: What to Do After a Suspected Spider Bite

1. Clean the Area

Wash the bite site gently with soap and water to reduce the risk of infection.

 2. Apply a Cold Compress

Use a cold pack or cloth-wrapped ice to help reduce swelling and numb the area. Apply for 10 minutes at a time, with breaks in between.

 3. Use Over-the-Counter Remedies

If needed, you can take:

• Antihistamines (like Benadryl) to help with itching and swelling

• Pain relievers (like ibuprofen or acetaminophen) for discomfort

• Hydrocortisone cream for topical relief

4. Keep an Eye on It

Watch the bite for changes. Most spider bites will improve within a few days. But if symptoms worsen — or if unusual reactions occur — it’s time to escalate.

When to Seek Medical Attention

While rare, some spider bites require professional treatment. Seek medical help if you experience:

• Increasing pain, swelling, or redness

• A spreading rash or ulcer at the bite site

• Muscle cramps, nausea, sweating, or chills

• A red or black central blister (especially with a surrounding “bullseye” pattern)

• Trouble breathing or swallowing (which may indicate an allergic reaction)

These can be signs of a venomous bite — or a secondary infection — and should be evaluated right away.

Know Your Local Spiders

In the U.S., the two most concerning spiders are the brown recluse and the black widow. Both are shy and prefer dark, undisturbed areas, but bites from either can cause serious reactions in some individuals.

 Black Widow

• Shiny black body with a red hourglass shape on the abdomen

• Bite may cause muscle cramps, sweating, and nausea

• Typically hides in garages, sheds, crawlspaces, and woodpiles

Brown Recluse

• Light to medium brown with a violin-shaped marking

• Bite may be painless at first, then develop into an ulcer or open sore

• Often found in attics, closets, behind furniture, or inside boxes

If you live in an area where either of these spiders is known to be active — or if you’ve seen them in or around your home — it’s smart to take extra precautions.

How to Prevent Spider Bites in the First Place

Spider bites usually happen when a spider feels threatened — often because it’s been accidentally trapped between skin and clothing, bedding, or shoes.

To reduce your chances of being bitten:

• Shake out shoes, towels, and clothing before wearing

• Don’t leave laundry or blankets on the floor

• Declutter storage areas, especially basements, attics, and sheds

• Wear gloves when cleaning out garages or moving boxes

• Seal cracks and gaps around doors, windows, and foundations

• Keep your home and outdoor spaces clear of spider webs

Consistent pest control can also help manage indoor spider populations — especially if your home is prone to insect activity (which spiders feed on).
