TL;DR: How To Treat And Control Scorpions
Step 1 — Seal where they are getting in
Scorpions can flatten themselves more than most people realize, so be thorough when sealing cracks and openings.
Step 2 — Spray with Lambda-cyhalothrin (micro-encapsulated)
Use 0.8 ounces per gallon of water.
Step 3 — Monitor the situation
Place a few sticky insect monitoring traps around the house and check them from time to time to monitor pest activity.
Helpful tip:
If you are actively looking for scorpions, a black light will make them glow.
Scorpions are tough because they can hide in very small spaces and slip into a home through openings most people would never notice. If you want to get rid of them, the best approach is simple: seal the entry points first, then apply a thorough treatment inside and outside the home.
Scorpion control works best when you focus on two things:
- Stopping them from getting inside
- Treating the places where they hide
If you do both well, you can make a big difference.
Because body shape, pincer size, and tail structure vary so much, it’s usually more helpful to focus on prevention and monitoring rather than trying to ID the exact species — especially since nobody wants to get close enough to a scorpion to inspect the fine details anyway.
Why Scorpions Get Into Homes
Scorpions usually end up inside because they find a gap they can squeeze through and a sheltered place to hide once they get in.
That’s what makes sealing so important.
Unlike some pests, scorpions do not need a large opening. They can flatten themselves quite a bit, so even small cracks and gaps can be enough.
That’s why the first step is always to check the structure carefully and seal as much as possible.
Step 1 — Seal Cracks, Gaps, and Entry Points
If you want lasting scorpion control, start here.
Scorpions are very good at squeezing into narrow spaces, so you need to be thorough. Look closely around the home for places where they may be entering.
Focus on areas like:
- cracks around doors and windows
- foundation gaps
- small openings around utility lines
- garage door edges
- damaged or loose door sweeps
- gaps under exterior doors
Check Door Sweeps and Garage Door Seals
Two of the most common entry points are:
- door sweeps
- garage door seals
If those are worn out, bent, cracked, or not sealing tightly, scorpions may be getting in there.
Seal Weepholes the Right Way
Weepholes can also be an entry point.
A good option is copper rodent exclusion mesh. It helps block pests while still allowing the weepholes to drain water when needed.
Do not use steel wool. It rusts quickly, and it is flammable.
Step 2 — Spray With Micro-Encapsulated Lambda-Cyhalothrin
Once the home is sealed as well as possible, the next step is to treat the structure and nearby hiding spots.
Use Lambda-cyhalothrin (micro-encapsulated) at:
0.8 ounces per gallon of water
This type of product is a good fit for scorpions because a micro-encapsulated formulation leaves behind small capsules of insecticide on treated surfaces.

Why a Micro-Encapsulated Product Helps
Scorpions pick up insecticide by moving across treated areas.
A micro-encapsulated product helps leave more material behind on the surface, which improves contact as scorpions travel through cracks, edges, and hiding places.
That’s why this type of treatment works best when applied carefully to the spots where scorpions actually move.
How to Apply the Spray Indoors
Apply the product indoors as a crack and crevice treatment using a coarse spray.
Focus on:
- cracks and crevices
- baseboard edges
- entry points
- hidden areas where scorpions may travel or rest
A coarse spray helps place the treatment where it needs to be without overapplying it.
How to Apply the Spray Outdoors
Use the same mix outdoors and apply it as a 3-foot perimeter around the house.
Treat:
- the base of the structure
- entry points around the exterior
- firewood piles
- places where scorpions can hide near the home
This outdoor treatment is important because many scorpion problems begin outside, and the closer they are to the structure, the more likely they are to end up indoors.
Spray Firewood Piles and Other Outdoor Hiding Places
Firewood piles are one of the most common places for scorpions to hide.
Be sure to spray:
- firewood piles
- sheltered hiding areas near the home
- any spot in the immediate vicinity where scorpions may be resting during the day
The goal is to reduce the number of protected places they can use near the structure.
How to Monitor for Scorpions 🦂
Sticky traps are one of the easiest ways to confirm scorpion activity, track where they’re coming from, and make sure your sealing and treatments are working. Scorpions wander at night and hug edges, so well‑placed monitors give you real data instead of guessing.

Where to Place Sticky Traps
Put glueboards in the spots scorpions naturally travel:
- Along baseboards, especially near exterior walls
- Behind furniture that sits close to the wall
- Next to door frames and sliding glass doors
- Inside garages, along the wall where it meets the floor
- Behind stored items in the garage or shed
- Near plumbing penetrations (laundry room, bathrooms, kitchen)
- Along attic entry points or inside the attic near edges
- Behind or beside beds if you’ve seen scorpions indoors
Placement Tips
- Keep traps flush against the wall — scorpions follow edges, not open floors.
- Use multiple traps in different rooms to see where activity is strongest.
- Replace traps when they get dusty — dust kills the stickiness fast.
- Try to hide traps from kids and pets by tucking them behind furniture or under items.
- Be careful with pets — a glue trap stuck to a paw or tail can be traumatic and difficult to remove.
Why Monitoring Helps
- It helps confirm whether scorpions are still entering the home.
- Scorpions often stay localized to one area before spreading.
- Monitoring shows you exactly where to seal, dust, or treat.
- It gives you peace of mind after treatment or sealing work.

Use a Blacklight to Find Scorpions
If you are trying to locate scorpions, a blacklight can be very helpful.
Scorpions glow under a blacklight, which makes them much easier to spot when checking dark areas, garages, patios, storage spaces, and the outside of the home.
This can help you find hiding spots and figure out where activity is strongest.
Scorpion Control Summary
If you want to get rid of scorpions, start by sealing every opening you can find. Since scorpions can flatten themselves and squeeze through surprisingly small gaps, details matter.
Then treat the home with micro-encapsulated Lambda-cyhalothrin at 0.8 ounces per gallon, applying it:
- indoors as a crack and crevice treatment
- with a coarse spray
- outdoors as a 3-foot perimeter
- on firewood piles
- in nearby hiding places
Also check:
- door sweeps
- garage door seals
- weepholes, using copper exclusion mesh instead of steel wool
For ongoing monitoring, place sticky insect traps around the house and check them periodically. If you are actively searching for scorpions, use a blacklight to help spot them.
Done thoroughly, this is a simple and effective way to get scorpions under control.
Scorpion FAQ
General Scorpion Questions
Are scorpions in the United States dangerous?
Most scorpions in the United States are more intimidating than dangerous. Their sting is painful, but in most cases it does not turn into a serious medical emergency.
Compared to some of the dangerous species found in other parts of the world, most U.S. scorpions are much less medically significant.
Are Florida scorpions dangerous?
Florida scorpions are usually not considered highly dangerous. They can definitely sting, and it can hurt a lot, but they are generally more of a painful nuisance than a major medical threat.
Which scorpions are the most dangerous in the U.S.?
In the United States, bark scorpions are the main species associated with more serious stings. They are the scorpions most likely to require medical attention.
Their range is generally from California across the Southwest into West Texas.
Scorpion Sting Pain and Symptoms
What does a scorpion sting feel like?
A scorpion sting is usually sharp, sudden, and burning. For many people, it can feel worse than a bee sting even when it is not especially dangerous.
I sat on one when I was about 6 years old in Florida, and it hurt bad. I’d say it was probably about twice as painful as a bee sting. But that was really the end of it. By the next day, it barely even left a red mark. That is pretty typical of the less dangerous Florida species.
Do scorpion stings usually leave a bad mark?
Not always. Many stings cause intense pain at first but leave very little visible irritation afterward. In milder cases, the pain is much worse than the appearance of the sting site.
When a Scorpion Sting Becomes Serious
How often do scorpion stings require medical treatment?
Only a small percentage of scorpion stings require medical intervention. Roughly 5% are serious enough to need medical care, and those cases are almost always associated with bark scorpions rather than the weaker species found in places like Florida.
When should I seek medical help for a scorpion sting?
You should seek medical attention right away if the person who was stung develops severe pain, trouble breathing, vomiting, drooling, muscle twitching, or other symptoms that seem unusually intense.
Children, older adults, and anyone with a history of strong allergic reactions should be watched more carefully.
Scorpions Around the World
Are scorpions outside the U.S. more dangerous?
Yes. In many parts of the world, scorpions are much more dangerous than the species most people deal with in the United States.
Higher-risk areas include:
- India
- North Africa
- the Middle East
- parts of Latin America
In some of these regions, scorpion stings are much more likely to require medical care.
Where are scorpion stings most serious worldwide?
India is one of the better-known high-risk areas, and in some places, estimates suggest that roughly 20% to 30% of scorpion stings may require medical intervention. That is far different from what we usually see in the United States.
Scorpions in the Home
Should I worry if I find a scorpion in my house?
You should take it seriously, but you do not need to panic. If you find one scorpion indoors, it means you need to start looking closely at how it got in.
Check:
- door sweeps
- garage door seals
- cracks and gaps
- weep holes
- firewood piles
- hiding places around the home
It is also smart to place a few sticky insect monitoring traps around the house so you can keep an eye on activity.
Does one scorpion mean I have an infestation?
Not necessarily. Sometimes one scorpion is just one scorpion. But it does tell you that the home has an opening, a conducive hiding area, or enough prey around the structure to support them. That is why sealing entry points and treating likely hiding spots matters.
