How Do Scorpions Get In the House? (And How to Keep Them Out)

Wondering how do scorpions get in the house? That’s the kind of question that will keep you up at night. It’s also the kind of question that invites some pretty uncomfortable answers. Yet, we’re going to answer them. Starting with one rough truth: If you live in a hot, dry climate, you’re living in scorpion country, my friend.

And the trouble with scorpions – apart from the fact that they look like something from a horror movie and can cause painful stings – is that they have no respect for your personal boundaries. Even that annoying neighbor who borrows your stuff and never returns it doesn’t come into your bedroom at night and hide in your shoes. At least, I really hope not.


So if you come face to face with a scorpion in your home, or if you’re just anxious to make sure that it never happens, let me share with you exactly how scorpions find their way into homes. Specifically, your own.

You have an open door policy

If you want to understand how a scorpion may get into your house, you have to think like the scorpion. Now, I’m not suggesting you start crawling around on the floor dismembering insects with your pincers before stuffing them into your mandibular mouthparts.

That’s not going to endear you to anyone. What I mean is that you should try to see your home from a more arachnid point of view.

As it turns out, it’s not as difficult as you’d think. You see, scorpions want what we all want: a quiet place to stay out of the hot sun and a regular supply of food and water.

It’s searching for these requirements that often leads scorpions to enter people’s houses. But generally, they won’t come and knock on the door. Although scorpions can and do enter a home through an exterior door that’s left open too long, it’s just as likely that they’ll come in via some other route.

Maybe there’s a slight gap where your dryer vent comes through the wall. Maybe there’s a tiny space that wasn’t filled properly when the windows were put in. Maybe there’s a crack in the foundation of your house that you never realized was there.

To a scorpion, and to lots of other pests, all of these things are like flashing welcome signs outside a friendly bar. They won’t hesitate to take advantage of an invitation like that.

Once you start looking, you might be surprised by how many gaps and holes there are in your house. And scorpions don’t need a lot of space. Even a small gap under a door can be enough to let them in. Scorpions can fit through spaces as small as 1/16 of an inch, or 1.5mm – that’s barely more than the thickness of a credit card!

So if you find gaps and holes in your exterior walls, go ahead and seal them up with caulk or something similar. Chances are, a scorpion can fit through any gap you find.

You already have a scorpion food source

It’s not a pleasant thought for anyone to think about scorpions living inside the walls of their home. But that’s usually the first place they end up. These areas often have a large population of other insects such as crickets that scorpions love to feed on.

Plus, with the moisture that condenses on the outside of water pipes and air conditioning ducts, a scorpion can live a happy life in these spaces where people never go.

The only good thing about a scorpion inside your walls is that it can’t do you any harm. If it’s not in your actual living space, the two of you may share a house and yet never meet, like that weird college roommate who always kept their door closed.

But there’s no guarantee that scorpions will stay put. And when they start showing up in your kitchen, your living room, your bedroom, it’s time to draw the line.

Holes in interior walls are often even more poorly sealed than those in the exterior of the house. Check around the pipes under your sinks and tubs, and around furnace and air conditioning vents. Pay attention to gas fireplaces and under your kitchen stove.

It can be a lot of work, but think of it like this: with every hole you fill, the chances of you running into a scorpion get lower. As long as it’s safe to do so, get out your caulk gun and seal those holes up.

Scorpions can get into your house in any number of ways. But we can all be thankful that they don’t fly, or teleport, or swing on ropes of silk like their spider cousins. If a scorpion wants to get inside your house, she needs to find a gap she can crawl through. Seal up all the gaps you can, and say goodbye to scorpion visitors. It’s not easy but it is pretty simple. Now go make your house scorpion-proof!
