I found a scorpion in my house…are there more? This is the most common question asked by anyone who’s ever discovered a scorpion in the house.
That is, after you scream like a little girl, jump on a bed or chair, and throw something at the eight-legged home invasion. No shame in this, by the way, we’ve all done it.
But once you’ve recovered from the initial shock, you may cycle through a range of emotions. First, extreme worry that you may have a scorpion infestation on your hands. Then, hope that it was a lone scorpion who didn’t have any friends and family.
And then the fearful question: “If I found one scorpion, are there more lurking nearby?”
Before your mind wanders further to all kinds of skin-crawling assumptions about your home and the surrounding environment, let’s put this matter to rest.
Here are a couple things you need to know about scorpions.
Do Scorpions Live in Groups?
Let’s start with the good news: Scorpions aren’t social creatures. Unlike ants or bees, they don’t have a queen nor do they live in a colony. Unlike bed bugs, they don’t release pheromones that signal safe places for them to nest together.
Scorpions are lone wolf individualists who prefer to live, hunt, and sleep alone. The only times scorpions actively seek out other scorpions is to mate.
So if you found one scorpion, it’s not likely that it brought friends and family with it.
But before you break out the champagne, there is an exception: bark scorpions. Bark scorpions are the only social scorpion that’s likely to be found in urban areas.
What Time of Year Is It?
Even bark scorpions aren’t always social – they tend to come together out of necessity. For example, during the winter, they will congregate in a nest of up to 30 scorpions to hibernate together.
So if it’s approaching the colder months and the scorpion you found in your home is a bark scorpion, there is a good chance that there are more nearby.
How Do Scorpions Get in the House?
Since scorpions prefer to live and hunt alone, there is a good chance that the scorpion you found was a solitary visitor. Finding just one scorpion doesn’t necessarily mean you’ve got an infestation on your hands.
But here’s the thing: if one got in, that means more can follow.
Finding a scorpion in your home is alarming for exactly this reason. It means that your house is an attractive opportunity for at least one scorpion so it stands to reason that any other stragglers that may happen by will think the same.
Where Do Scorpions Come From?
Scorpions don’t have any burning desire to see the world. In fact, these solitary creatures don’t like to stray far from their home at all.
As such, scorpions move very little in their lifetime. One observational study found that in a period of two hours, the maximum travel distance of a scorpion was 104.37 meters. That’s just a little over a hundred yards.
For the most part, scorpions don’t tend to travel far. So if you found a scorpion in your home, it probably came from somewhere very close by. That means the immediate area around your home could be a hospitable place for scorpions to live and breed.
I Found a Scorpion in My House. Are There More?
Just because you found a scorpion in the house, it doesn’t necessarily mean there are more. Whether you do or don’t have more scorpions in the house depends on factors like:
- The type of scorpion you found. Most scorpions live and hunt alone. The exception is the bark scorpion.
- How the scorpion got in. If your house has lots of cracks and crevices for scorpions to squeeze through, the more likely it is to attract more than one scorpion visitor.
- The time of year it is. In the colder months, scorpions are looking for warm, safe places to hibernate. A human home makes an ideal spot.
- How scorpion friendly your lawn is. Scorpions don’t travel far so if you find one in your home, that means it probably came from your lawn. If your lawn has rotting wood, plenty of insects, damp and dark places, it is a scorpion-friendly zone.
Overall, finding a single scorpion in your home does not mean you have an infestation on your hands. But it does mean two very important things: That your house and lawn is an attractive place for scorpions. And that there are entryways into your home for scorpions to get into.
We’ll get to that in a bit. But first, let’s address this matter of whether there are more scorpions lurking around.
How to Find Scorpions
Aside from patiently waiting for more to show up in your home and confirm your theory, the only way to know if there are more scorpions in the area is to find them yourself. Here are your three options to do this.
Call a scorpion professional
The first option to check for more scorpions is to call a professional in to do so. Scorpion pest control costs tend to range from $200 to $300, with $250 being the national average.
As you can see, this is the priciest choice but may be for you if you’re a rational, normal human being who is terrified of arachnids of all shapes and sizes.
In the interests of balance, though, I need to assume that some of you aren’t big chickens like myself, and would like to take matters into your own hands.
Search them out for yourself
If you handle the DIY route, you can definitely do a scorpion inspection yourself.
The best way to do so is to wait until dark and use a UV flashlight or other light source to scan your home and its surroundings.
Scorpions are notoriously stealthy (until one scares the daylights out of you); so this should, theoretically, catch them in the act of feeding/hunting/lounging around on your premises.
Set traps and monitor them
A passive option that can alert you to the presence of more scorpions in the house is to lay glue traps. Scorpion glue traps are a pesticide-free, effective and affordable way to catch any scorpions that may be wandering around your house.
Set the traps in dark, preferably humid, areas that scorpions are going to be drawn to and be sure to monitor them frequently.
Keep in mind that glue traps don’t actually kill scorpions so when you find a scorpion stuck in the trap, it’s going to be alive and angry. Handle with care.
