Most Common Types of Scorpions in Homes
by Allison Kirschbaum | July 18, 2025 | Blog
Scorpions have a way of turning an ordinary evening into a moment of panic, especially when one shows up in your basement, attic, or garage. While they often prefer the outdoors, it’s not unusual to find scorpions in the house, especially during dry or hot seasons.
For some homeowners, a scorpion sighting is a rare and isolated event. For others, it’s a recurring problem, or worse, a sign of a full-blown infestation. Below is a comprehensive guide that will help you identify the most common types of scorpions found in and around homes, understand their behavior, and learn how to effectively eliminate scorpions and prevent their return.
What Are Scorpions?
Scorpions are predatory arachnids closely related to spiders, mites, and ticks, belonging to the order Scorpiones with over 2,000 species distributed worldwide. These ancient arthropods are characterized by their distinctive segmented bodies featuring robust pincers (pedipalps) for capturing prey and curved, flexible tails that terminate in venomous stingers used for both hunting and defense. Their remarkably adaptable nature enables them to thrive across diverse environments ranging from arid desert regions to tropical rainforests, temperate woodlands, and even high-altitude mountain areas.
Found on every continent except Antarctica, scorpions demonstrate exceptional evolutionary success through specialized anatomical features including sensory organs that detect ground vibrations, UV-fluorescent exoskeletons visible under blacklight, and efficient metabolisms that allow survival without food for extended periods. Most species measure 1-4 inches in length, though some tropical varieties can reach 8 inches or more.
Their nocturnal hunting behavior, combined with their ability to squeeze through surprisingly small spaces, makes them frequent invaders of human dwellings in regions where outdoor populations exist. Despite their fearsome appearance, most scorpion species pose minimal danger to humans, with only about 30 species worldwide possessing venom potent enough to cause serious medical complications.
Life Cycle of Scorpions
Unlike many other arachnids, they don’t lay eggs. Instead, the female gives birth to a brood of live young called scorplings, which climb onto her back immediately after birth. They remain there for a week or two until they’ve molted for the first time, gaining a bit more independence and a tougher exoskeleton.
After leaving their mother, the scorplings go through several more molts over the next 1 to 3 years before reaching full maturity. The number of molts varies by species and environmental conditions. Once mature, scorpions typically live between 3 and 8 years. Throughout their lives, they are solitary hunters, using their pincers and venomous stinger to capture prey and defend themselves.
Why Scorpions Wander in Your House or Yard
Scorpions end up in homes and yards usually in search of food, water, or shelter. These nocturnal hunters feed on insects like crickets, roaches, and spiders, so if your property has a steady insect population, it’s basically an open invitation for scorpions to make a home there.
Dry or hot weather also drives scorpions to seek cooler, more humid environments, which can lead them indoors through cracks, vents, and poorly sealed doors or windows. In the yard, they may hide under rocks, woodpiles, or dense vegetation where they can stay out of the sun during the day.
New construction or nearby land clearing can also disturb their natural habitats, causing them to relocate to nearby homes. Seeing scorpions in the house or yard doesn’t necessarily mean there’s a full-blown infestation, but it’s a clear sign that conditions are favorable for them.
To reduce the risk of scorpion stings, avoid leaving shoes, clothes, or damp towels outside, as these items can easily become hiding spots. Before using them, give all towels, clothing, and footwear a quick shake, especially if they’ve been near the pool or left outdoors. When working in the yard, wear gloves and always wear shoes outside, particularly in the evening when scorpions are more active.
3 Most Common Types of Scorpions Found in and Around Homes
There are over 1,500 known species of scorpions globally, but only a handful tend to appear in residential areas across the United States. Let’s take a closer look at the three types of scorpions most frequently found near homes and what makes each one unique.
1. Arizona Bark Scorpion (Centruroides sculpturatus)
The Arizona bark scorpion is one of the most well-known and venomous types of scorpions in the United States, particularly in Arizona, New Mexico, and parts of California. The Arizona bark scorpion is a small, slender scorpion, approximately 2.5 to 3 inches long, characterized by its light tan to yellowish-brown color, narrow pincers, and a curved tail.
Among the various types of scorpions, the Arizona bark scorpion often holds its tail to one side rather than arching it over its back. It also has the unique ability to climb walls, furniture, and even hang from ceilings, setting it apart from many other types of scorpions. This agility enables the Arizona bark scorpion to seek out cool, dark crevices indoors, often hiding inside shoes, under sinks, or behind baseboards.
Its ability to flatten its body allows it to slip through openings as small as 1/16 of an inch. In outdoor spaces, it favors similar hiding spots, typically sheltering under bark, rocks, or debris during the day to escape the heat.
The Arizona bark scorpion is the only scorpion in the U.S. with venom potent enough to cause severe symptoms in humans, particularly in young children and pets. The sting can cause pain, numbness, nausea, vomiting, and sometimes even breathing difficulties. Seek immediate medical attention after a scorpion sting.
2. Desert Hairy Scorpion (Hadrurus arizonensis)
Also known as the giant desert hairy scorpion or the Arizona hairy scorpion, it is one of the largest types of scorpions in North America, measuring between 6 and 8 inches long. It has a tan to olive-green body with a darker back, yellow legs, and pincers, and its tail is covered in fine browning-black hairs that help detect vibrations.
Desert hairy scorpions thrive in arid environments, where they burrow in sandy soil and take shelter under rocks or logs to escape the daytime heat. Although they typically stay outdoors, they may occasionally wander into garages or basements through small gaps in search of food or moisture.
They’re especially attracted to areas such as swimming pools, irrigated landscapes, and spots with outdoor lighting, where insects like beetles, cockroaches, moths, and crickets tend to gather.
Desert hairy scorpions are venomous, but their venom is not potent enough to be fatal to humans. Their stings are often compared to the pain of a honeybee sting, causing localized swelling and discomfort. These scorpions are generally non-aggressive and will sting only when provoked or threatened.
3. Striped-Tail Scorpion (Paravaejovis spinigerus)
The striped-tail scorpion, often referred to as the “devil scorpion,” is typically found throughout the arid regions of the southwestern United States. Measuring between 2 and 3 inches long, this scorpion has a pale yellow to tan body with distinctive dark brown or black stripes along the ridges of its thick tail, which contrasts with its slender pincers.
Striped-tail scorpions favor dry environments and typically burrow beneath rocks, logs, or debris. They’re well-adapted to a variety of terrains, including sandy deserts and rocky hillsides. While they’re less skilled at climbing or entering buildings compared to bark scorpions, they may still take cover under items like shoes or sleeping bags.
Due to their skittish nature, striped-tail scorpions are more likely to sting when threatened. However, its sting is generally not life-threatening. The pain from a striped-tail scorpion sting is typically comparable to that of a bee or wasp sting, causing localized pain and swelling. However, individuals with allergies may experience more severe reactions.
How to Get Rid of Scorpions Properly
If you’re wondering whether you have scorpions in the house or around your property, the most obvious signs are spotting one at night and finding shedded exoskeletons. If you’ve seen one scorpion, there’s a good chance others are nearby.
Once you’ve confirmed their presence, here’s how to get rid of scorpions properly:
Remove Scorpions With Caution
Since there are various types of scorpions with different levels of danger, attempting to handle them yourself isn’t recommended. While most scorpions found around homes are not deadly, their venom can still be harmful, especially to young children, the elderly, or individuals with allergies.
If you are unsure how to handle a scorpion properly and encounter one in your home, wear thick gloves to protect your hands from potential stings. Be careful to avoid sudden movements that might startle the scorpion and trigger a defensive response. Use tools like tongs or long forceps that are 10 to 12 inches long to gently pick it up from behind the stinger, keeping your hands well out of range.
Alternatively, you can trap it by placing a glass jar over the scorpion and sliding a stiff piece of paper underneath to contain it. With the sheet of paper securely over the mouth of the jar, invert the jar, and the scorpion will fall to the bottom.
Screw a secure lid onto the jar to prevent escape, then release the scorpion in a safe outdoor area away from your home, such as a wooded area, garden, or shrubbery, where it can thrive without posing a risk to you.
Call a Professional Pest Control Service
If you’re unsure about the species or uncomfortable handling it, it’s best to contact a licensed pest control service. A professional pest control service has the tools, expertise, and knowledge to remove visible scorpions and identify hidden spots where they may be nesting or hiding. They also ensure the proper treatment methods are used to thoroughly address scorpions in your home.
4 Ways to Prevent Scorpions in and Around Your Home
Fortunately, there are simple steps you can take to reduce their presence in and around your home. Here are four ways to prevent scorpions from making themselves at home on your property.
1. Eliminate Entry Points
Scorpions can squeeze through incredibly small openings. Inspect the exterior for cracks in the foundation, gaps around windows and doors, and holes in screens. Use caulk to seal any cracks and install weather stripping or door sweeps to close gaps at entry points. Fix or replace any damaged window or door screens to prevent scorpions from entering the house.
2. Reduce Outdoor Attractants
Scorpions thrive in cluttered, shaded areas outdoors. To make your yard less appealing, clear out piles of wood, rocks, and other debris that offer hiding spots. Trim overgrown vegetation and keep tree branches and bushes from touching your home’s exterior. Scorpions are also drawn to moisture, so fix any leaky outdoor faucets and eliminate standing water around your property.
3. Control Indoor Environments
Keep floors and storage spaces tidy by avoiding clutter and keeping items organized and off the ground. To catch scorpions moving through your space, place sticky traps in common crawl areas, such as along baseboards and near doors. For added visibility, conduct nighttime inspections using an ultraviolet (UV) flashlight, as scorpions naturally fluoresce under ultraviolet light, making them easier to spot in the dark.
Another useful tip is that scorpions cannot walk on clean glass. If your doors or windows have glass screen inserts, make sure to clean them weekly. If you come across a scorpion, avoid swatting it with a fly swatter, as this can cause baby scorpions to scatter everywhere. Plus, striking a scorpion may provoke it to sting since the impact can force its stinger into your skin.
4. Apply Natural Repellents
If you prefer non-chemical methods, several natural options can help deter scorpions. Essential oils, such as lavender, peppermint, and cinnamon, are known to repel them. Simply mix a few drops with water and spray around baseboards and windows.
Diatomaceous earth is another option. Sprinkle it around the home’s perimeter or in areas where scorpions might enter. This fine powder may harm scorpions by damaging their exoskeletons, leading to dehydration and eventually death. However, it’s essential to select a product specifically labeled for pest control, as not all diatomaceous earth is designed for this purpose.
Boric acid may also help control scorpions, but it must be used with caution. Keep it out of reach of children and pets, and always follow the product’s instructions carefully.
Scorpion FAQs
Here are some frequently-asked questions by homeowners about dealing with scorpions.
How dangerous are scorpions?
Most scorpion species pose minimal danger to humans, with stings typically causing localized pain, swelling, and numbness similar to bee stings. However, certain species like the Arizona bark scorpion can deliver medically significant venom causing severe pain, muscle spasms, and neurological symptoms requiring immediate medical attention. Children, elderly individuals, and people with compromised immune systems face higher risks from scorpion stings. While fatalities remain rare in areas with proper medical care, all scorpion encounters should be treated seriously.
Where are you most likely to find scorpions?
Scorpions prefer dark, humid hiding places during daylight hours including under rocks, logs, and debris piles in outdoor environments. Indoors, they commonly hide in closets, storage areas, bathrooms, and basements where moisture levels remain higher. They frequently shelter in shoes, clothing, bedding, and towels left on floors. Desert regions, southwestern United States, and areas with rocky terrain or dense vegetation provide ideal outdoor habitat. They’re most active during nighttime hours when hunting for prey.
How do I know I have a scorpion infestation?
Scorpion infestations are identified through direct sightings, especially at night when they become active hunters. Look for shed exoskeletons in hiding places, as scorpions molt multiple times during development. UV blacklight inspection reveals live scorpions, which fluoresce bright blue-green under ultraviolet light. You might also find dead prey insects in areas where scorpions hunt. Increased sightings during warm months or after heavy rains often indicate established populations requiring professional assessment and treatment.
What are scorpions attracted to?
Scorpions are primarily attracted to abundant prey populations including insects, spiders, and other small arthropods that serve as their primary food sources. They seek consistent moisture sources such as leaky pipes, air conditioning condensation, and irrigation systems. Dark, undisturbed hiding places like woodpiles, storage areas, and cluttered spaces provide ideal shelter. Outdoor lighting that attracts insects creates concentrated feeding areas, while landscape features including rock gardens, mulch beds, and dense vegetation offer protective harborage close to homes.
Do scorpions attack people?
Scorpions are defensive rather than aggressive creatures that sting only when threatened, cornered, or accidentally contacted. They don’t actively hunt humans but may sting when inadvertently trapped against skin by clothing, shoes, or bedding. Most encounters occur when people unknowingly disturb scorpions hiding in dark spaces.
Their primary defense strategy involves hiding rather than confrontation. However, female scorpions protecting young or scorpions surprised in confined spaces may sting defensively. Proper precautions during outdoor activities and careful inspection of clothing significantly reduce sting risks.
