Spiders are blamed
for all kinds of things that turn out to be skin infections or some
other bug’s fault. Most don’t even have fangs long enough to break your
skin. When they do bite, they're typically harmless. In the U.S., only
the black widow and brown recluse have venom strong enough to really
hurt you. And their bites are rarely deadly to humans.
Black Widows
This spider’s
telltale sign is the red hourglass shape on the bottom of its big, round
abdomen -- the back part of the body. Black widows are shiny and black
and about half an inch long. You can find them anywhere in North
America, but mostly they’re in the southern and western areas in the
U.S. They like quiet, out-of-the-way places like closets, sheds,
garages, and woodpiles.
What’s a Black Widow Bite Like?
The bite feels like
a pinprick, so you may not notice it. The first signs might be small,
red marks with some swelling. Within an hour, it’ll hurt a little more,
and the pain might spread to your back, belly, and chest. You might have
stomach cramps, and your belly might feel a little stiff. You may also
sweat a lot. In serious cases, you can have trouble breathing, along
with a fast heart rate, nausea, and vomiting. The area around the bite
may continue to get redder and more swollen.
What’s a Brown Recluse Bite Like?
You might feel a
little sting at first, but it’ll hurt more over the next 8 hours. You
also might see a small white blister that has a red ring around it, like
a bullseye. Sometimes, the skin in the middle of the bite can turn blue
or purple, and you may have an open sore that gets bigger for up to 10
days. It doesn’t happen often, but some people also have other symptoms
like fever, chills, rash, and an upset stomach.
When to See a Doctor
Get checked out
right away if you have symptoms beyond the bite, like serious pain in
your belly, cramps, throwing up, or trouble breathing. You also should
see your doctor if you have an open sore or a bullseye mark, or if the
bite gets worse after 24 hours. Look out for things like pain around the
bite getting worse, redness that’s spreading, and fluid coming from the
bite. If you can do it safely, take the spider with you, even if it’s
dead.
Treatment for Brown Recluse Bites
This is mostly
about managing the wound so it doesn’t get infected. If you have a bump
and redness, your doctor might recommend antihistamines or a cream to
help with swelling and itchiness. For an open sore, you need to clean it
daily and use antibiotic cream. From there, you should keep an eye on
things, especially for symptoms beyond the bite, like fever or chills.
Allergic Reactions
It’s not very
common, but just like with bee stings, some people are allergic to
spider bites. Watch for swelling in your face or mouth, trouble talking
or swallowing, tightness in your chest, or trouble breathing. If you
feel any of these symptoms or see them in someone you’re with, get help
right away.
How to Prevent a Spider Bite
If you’re poking
around in woodpiles, sheds, attics, and other areas, wear long sleeves
and a hat, and tuck your pants into your socks. Make sure to shake out
work gloves, boots, and clothes you haven’t used in a while, because
spiders can hide in them, too. And don’t keep rocks, lumber, or firewood
near your house. Inside, don’t put your bed directly against the wall,
and don’t store things under it.
