Where do brown recluse spider hide

Brown recluse spider bites are painful. As per healthline.com, “if you don’t get medical attention asap, the bite wound will develop skin necrosis.”

Skin necrosis is the condition where the bite wound develops an infection.

But even then, a bite from brown recluse spiders won’t kill you.

Why? 

Because the venom that it carries is simply not strong enough to kill a living being as big as a human. 

Brown recluse spider bites won’t kill a baby either.

Hence, there’s no need to panic. If a brown recluse spider bites you, then use an antiseptic cream on the bite wound and go straight to a doctor for treatment.

You’ll be fine!

Why Do Brown Recluse Spiders Bite Humans?

Spiders are shy. They’ll do whatever they can to avoid human contact.

But there are certain situations when the brown recluse spiders can bite you. However, these conditions are when it feels under threat.

Brown recluse spiders hide in deep dark corners of your home. And when you’re getting rid of them or cleaning those places, and you don’t know they’re there then you can get a painful bite from the brown recluse spider.

That happens when you step on them barefoot, or when they’re pressed against your skin.

That bite is more of self-defense rather than a typical spider behavior.

Brown recluse spiders, and all spiders, do not willfully bite humans like mosquitoes. 

Spiders are predators. They’re not parasites that thrive on human blood. 

So, the chances of getting spider bites despite your home having a spider infestation is low.

What Happens When The Brown Recluse Spider Bites You?

Brown recluse spider bites are not immediately painful. In fact, the initial bite is painless. 

Brown recluse spiders have small fangs. And when they bite you, you’ll feel a slight sting.

But if you don’t treat the bite wound asap, severe pain and infection will develop over time.

After 4 to 8 hours of the bite, the brown recluse spider bite starts to get bad. Redness on the bite wound starts to appear. Then it’s followed by a burning sensation.

Some people can also feel that the bitten area is getting itchy.

Slowly, necrosis on the skin develops too. It means that the skin on the bitten wound starts to sink, and it gets dry. The hemotoxic venom in the brown recluse spider causes that.

A slight crater forms at the center of the bite wound followed by a reddish-blue halo around it.

In most people, the venom of the brown recluse spider is restricted only to the bitten wound. 

However, in some people, it may spread in their bodies. That causes the bite wound to expand.

Elderly and children can show severe reactions to brown recluse spider bites. These reactions include shivers, dizziness, vomiting, and a bit of fever too.

So, please see a doctor asap if a brown recluse spider bites you. You’ll be fine.
