What Is a Brown Recluse
Brown recluse spiders prefer warm climates and are usually found
in the central and southern United States. They often live in dark sheltered
areas, such as piles of wood, leaves, or rocks. They may also live inside
people’s homes or under their porches. Sometimes a brown recluse will
even hide in shoes or under clothes that have been lying on the floor for a
long time. Fortunately, they rarely bite people.
Brown recluse spiders have a dark, violin-shaped patch just
behind their heads. This mark can be hard to see, so it’s easy to mistake a
different kind of brown spider for a brown recluse. Still, you should
immediately call your doctor or go to the emergency room if you believe a brown
recluse spider has bitten you. Prompt treatment is especially important for
children, who often experience more severe symptoms.
What Causes a Brown Recluse
Spider to Bite?
Brown recluse spiders don’t generally bite
people. They’re not aggressive spiders and will typically only bite if they
feel trapped or threatened. They usually hide during the day and come out at
night to hunt for insects.
How Can I Avoid Being
It’s almost impossible to entirely get rid of
spiders from a home or building once they’re there. Sticky traps and
repellents can help reduce the number of spiders. You can take other
precautions to lower your chances of being bitten:
- Clean up clutter in your yard and basement, and
avoid stacking wood against the house. This can help remove the types of places
where brown recluse spiders like to live.
- Avoid leaving clothing on the ground. If you do,
be sure to shake it out before putting it on.
- Wear gloves when moving wood and rocks,
especially if you live in an area where brown recluse spiders are common.
- Be careful when taking things out of storage, as
brown recluse spiders often live in cardboard boxes.
- Be careful when putting on clothes that have
been lying on the ground for an extended period of time. Shake them out before
putting them on.
- Check shoes before wearing them.
What Are the Symptoms of a Brown
Recluse Spider Bite?
You usually don’t feel a brown recluse spider’s bite. In fact, you
might not even realize that you’ve been bitten if you don’t
actually see the spider biting you.
The bite may sting at first, but symptoms usually don’t
develop for several hours. You may feel pain, burning, or itching around the
site of the bite. The area may also become red.
Brown recluse spider bites are characterized by a unique pattern
of discoloration that often develops around the bite. The site of the bite may
turn a deep purple or blue color and be surrounded by a whitish ring and a
larger red area. There may also be a dark blister or ulcer by the bite. In some
cases, the ulcer caused by the bite can persist and grow for weeks.
Additional symptoms you may develop include:

conditions, such as kidney failure or seizures. In rare cases, a bite can lead
