Living in the desert can be scary for many reasons, but the scariest thing is the thought of how many things in the desert can kill you. Scorpions are definitely the poster children for scary desert predators. There are over 1,500 species of scorpions in the world and about 25 are harmful to people. Of those 25, of course, one of those is a native of the States. The Arizona Bark Scorpion is the most common and painful in North America. The following are some of the strongest reasons to stay away from these gruesome pests.

1. Their Sting!

Scorpion Stinger

Scorpions are equipped with a stinger. This stinger produces both poison and pain. This stinger is designed to paralyze prey by hampering the nervous system. In normal healthy adults, the most a scorpion sting should cause is just a sharp pain. This pain should slowly subside and be gone in 15-20 minutes. In more severe reactions, the venom in a scorpion’s stinger can be deadly to humans, especially the elderly and young children. In many it is known to cause numbness in the sting site, dizziness, difficulty breathing, and other similar symptoms.

2. Cannibalism

Scorpion Face

Scorpions are not nice. They commonly prey on each other for food. Young scorpions must stay away from their elders in order to avoid being lunch; even their mother. Once the scorplings climb off their mother, she sees them as prey. Biologists believe scorpions must have developed this trait in order to stay alive in the harsh conditions they live under.

3. Babies Everywhere!

Babies are typically a blessing, but when it comes to scorpions they’re more of a curse. A mother scorpion can have numerous amounts of scorplings in her batch, up to a couple hundred. Scorplings hatch and climb onto the mother’s back for the first couple of weeks of their lives until after their first molt. Then they climb off and scurry away to start their own adult scorpion lives filled with cannibalism and evil.

4. Intimidating Posture

Scorpion_PoseThese creatures may be small, but they were structurally designed to be feared. Their creepy numerous legs, along with their pincers and stinger, make them look like they’re ready to attack at the drop of a hat. Sometimes a scorpion doesn't even need to inject venom into its prey; with its pincers it can crush its victim. They‘re also covered in a hard exoskeleton that to those of us scared of the thing may seem impenetrable.

5. Tiny & Camouflaged

Scorpion Cammo These small, but viscous, insects do their best to remain hidden and can always squeeze their way into unwanted places. If you live in a desert area, then the chances of finding these guys in your home are very high. Many people have the horrible experience of being stung in their bed, while asleep. So next time you spot this natural desert predator be sure to keep your distance. If they’re common inside the home getting professional pest operators would be the best option.


Summer is finally upon us. Among all the summer vacations, family reunions, picnics, and days at the pool; something dangerous lurks. Desert cities like Las Vegas, NV, St. George, UT, Phoenix, AZ, and Mesa, AZ house a few unique and even dangerous pests. Here are three desert pests to watch out for this summer:

Desert Recluses

Commonly confused with the Brown Recluse spider, the Desert Recluse spider is equally as dangerous. Desert recluses are found in Southern Nevada, Southwest Utah, and Western Arizona. Not too many Desert Recluses invade the actual cities of Mesa or Phoenix; however, both cities do harbor the Arizona Brown Spider which is also in the recluse family. These recluse spiders hide in dark places. Desert Recluse spiders are tan in color, and have a dark brown violin shaped spot on their head. These spiders are not aggressive in nature, but do bite when bothered. Many homeowners in desert cities are bitten when they accidently touch the venomous spiders. When bitten, a victim will experience pain, swelling, and redness around the site. The site will begin to blister, causing open lesions and sores. Bites can take months to heal and even require skin grafts. Those with compromised immune systems, and the young and elderly, are at the most risk to a Desert Recluse bite. Death can be a result on rare occasions.

Arizona Bark Scorpions

Arizona Bark Scorpion

Throughout all of the southwest, Arizona Bark scorpions wreak havoc on unsuspecting homeowners. If you live in a desert city, you’ve seen one of these scorpions before. While most other species of scorpion live solitarily, these scorpions congregate in groups. When you see one of these scorpions in your Arizona, Nevada, or Utah home; there are bound to be more. Feeding on crickets and roaches near your desert home, these nocturnal pests ambush their prey. Typically, Arizona Bark scorpions come into your home looking for water and refuge from the elements. It is then when unfortunate encounters occur. Hiding inside your shoe, or underneath a discarded article of clothing or towel; these pests sting you when you accidently encounter them. Their stings cause an unpleasant reaction that can include nausea, numbness, vomiting, breathing difficulties or convulsions.

Sun Spiders

Because of the several embellished myths about their size, speed, behavior, appetite, and lethality; many people who encounter a sun spider are deathly afraid of them. Sun spiders, also known as camel spiders or wind scorpions, are neither spiders nor scorpions and have no venom. They do however, exhibit very aggressive behavior and may attack for no reason at all. They can run up to 10 mph and have large, powerful jaws that can produce an irregularly large bite. Antibiotic treatment is necessary if a bite becomes infected.

New Report: Microscopic Scorpions Crawl On You While You Sleep

microscopic scorpion Phoenix, AZ—A study conducted by The University of Phoenix has found, that during an average night's sleep, some 300 microscopic scorpions unknowingly crawl across your face, neck, and body as you slumber. These microscopic scorpions, which look a lot like lint when bunched together, are confined to the State of Arizona; but researchers fear outbreaks in Texas, and isolated parts of Nevada and Southern Utah are inevitable. It’s important to note that these microscopic scorpions cannot sting humans, unlike their cousin the Bark Scorpion. Their stingers are simply too small. The University of Phoenix’s lead entomologist, a Klaus Meine, issued the following statement regarding the microscopic scorpions:
"As you sleep, you become a virtual playground for these creeping pests just mere minutes after you fall asleep; inhaling dozens of the scorpions and swallowing at least 20 during an eight-hour period."
It gets worse. Meine added,
“While these microscopic scorpions are drawn to the moist and humid areas of the nose and mouth, they will also spend each night birthing hundreds of their young in and around your armpits.”
There is one surefire way to tell if you have a microscopic scorpion infestation, Meine continued.
“Like all other scorpions, these microscopic scorpions give live birth. Victims who suffer from a microscopic scorpion infestation will awaken with scorpion afterbirth in their bed sheets. It’s about this time a victim should know they are not alone in bed.”
At this time homeowners in Arizona, Texas, Nevada, New Mexico and Utah should be on high alert. There is no known cure for the microscopic scorpions, as this is a new report.  

*** Update: The Horrifying Truth About Microscopic Scorpions

The truth is, microscopic scorpions are not real, and according to this report, we do not swallow scorpions, spiders, or any other insect while we sleep.

April Fools!


Spring Baseball & Scorpions

Spring is in the air here in Arizona, and that can only mean one thing… MLB Spring Training! Every year, 15 Major League Baseball teams ascend on the Valley of the Sun for six weeks of preseason baseball. Teams like the Chicago Cubs, Los Angeles Dodgers, San Francisco Giants, and Cleveland Indians all square off in the Cactus League; preparing for the upcoming season. Teams frequently use players' spring training performances as a way of assigning starting roles and roster spots. While spring training attracts a huge number of fans and spectators who eagerly wait to see the promising new talent, all while enjoying the warm weather, which also happens to coincide with the beginning of the scorpion season here in Arizona. Nobody knows that better than Milwaukee Brewers GM, Doug Melvin, who was recently stung by a very venomous Arizona Bark Scorpion… The most dangerous scorpion found in the U.S.

Brewers GM Stung By Scorpion

The Milwaukee Brewers MLB club has descended on Maryvale Baseball Park, in Phoenix, AZ for their annual spring training. While in town, Doug Melvin, the General Manager of the Brewers, was stung by a scorpion. It all went down last Wednesday, March 5, 2013. Melvin and his wife had just enjoyed a night out in the Valley. Upon returning to their Phoenix-area condo after dinner, Melvin’s wife spotted a “bug” on the floor. After eyeing the bug, she shouted to her husband to take care of it. In an attempt to be the hero and save the day, the Brewers GM grabbed a tissue and picked up the bug—which happened to be a scorpion. The scorpion retaliated by stinging Melvin’s left middle finger through the tissue. Ouch! After the sting, Melvin’s arm began to tingle—kind of like hitting your funny bone. His left arm began to feel numb. The sensation moved from his arm to his shoulder. About this time, he began to worry that the venom might be spreading and eventually reach his heart. He headed to a Scottsdale emergency room where he was treated for the sting. After three hours in the ER, some pain medication, and some scorpion education, the Brewers GM made a full recovery. The next time he encounters a scorpion, he’ll likely just squash it with his shoe.

In Arizona alone, the Arizona Bark Scorpion is responsible for several thousand stings each year. With that being said, fatalities in the United States are rare, and generally limited to small/young children and adults with weakened immune systems. The symptoms of a Bark Scorpion sting include pain, tingling sensations, blurry vision, throat swelling, darting eyes, and tense muscles. Those experiencing an allergic reaction will have difficulty breathing and walking, and should seek medical attention.

The Arizona Bark Scorpion

The Arizona Bark scorpion is a golden tan in color, and can reach lengths of about two inches. They are frequently found in the southwest United States; predominately in the Sonoran Desert. Less toxic species of Bark scorpions have been discovered throughout areas in Southern Utah, New Mexico, Nevada and Texas. Bark scorpions prefer to hunt at night by ambushing their prey. They commonly dine on crickets and cockroaches.

Bulwark Exterminating is an expert when it comes to Scorpion Control, having treated some 25,000 scorpion infested homes.

I am a 5th Generation Arizonan, which is increasingly rare in this state due to the population growth over the last several years. So I am not sure what it is like to live in a state like Kansas during tornado season, or what it is like to live in Florida during hurricane season, or what it is like to live along the San Andreas Fault. I imagine, however, that it is similar to how I have always felt about living in Arizona with the Arizona Bark Scorpion, I have never thought much about it. WPicture of beach in St. Croixhen I was a teenager, I spent a summer in St. Croix in the Virgin Islands during hurricane season. I remember going through the preparations for a hurricane, including, buying bottled water, food and lumber to protect my parent's home and to prepare for hunkering down during the storm. It didn't seem out-of-the-ordinary because everything on the island stopped for the days leading up to the hurricane's landing. For the most part, once the events occurred, everything went back to normal. It was almost ritualistic for the natives in St. Croix. Back here in Arizona, the closest thing we have that compares to a Category 5 Hurricane is probably a micro-burst during a particularly bad monsoon or perhaps even a flash flood. Not quite the same as a massive hurricane. One of the next most dangerous things you might have to worry about as a resident of Arizona is our very own Arizona Bark Scorpion. The bark scorpion is considered the most dangerous scorpion in the United States and is also considered deadly, though victims of fatal stings usually have other underlying health issues, are either very young or very old, or are allergic and usually die due to complications from anaphylactic shock. Perhaps I am in the minority here in Arizona, but I neither check my shoes before I put them on nor do I shake my bed covers before climbing into bed to make sure that there aren't any scorpions lying in wait to poison me with painful neurotoxin. Well, it seems that maybe I should have been more careful because as I was cleaning up for the Christmas holiday, I picked up a cardboard box of Christmas presents that I just brought home from my in-laws (who must not keep up with their pest control). When I picked up the box, I put my pinky finger on a scorpion hiding under the box and for a brief moment, I could feel the scorpion trying to wiggle free and I dropped the box immediately; however, it was too late. The scorpion had injected me with its powerful neurotoxin and I felt an immediate pain in the middle of my pinky finger on my right hand. The sting felt like someone had poked me with a needle all the way into my bone. I quickly grasped my finger and squeezed tightly and the pain began to ease, but the damage had been done and my agony remained. Once I let go of my grasp and in the ensuing moments, the venom began to travel up my arm. 

Scorpion on FingerFirst, I felt the pain on the top of the back side of my hand where I could see the veins under my skin. Then, some moments later, I began to feel the neurotoxin work its way to my wrist where each time I felt my pulse, the pain seemed to grow stronger. Moments later, I felt it in my arm and then worse on the inside of my elbow. As I continued to work in the garage, I even felt the pain reach my shoulder. The pain was pretty strong during those first few moments but not strong enough for me to feel like I needed to go to the hospital. (However, many people, including real world sources, recommend that you do go to the hospital after being stung by a scorpion.) After several minutes, the pain was quite tolerable though very uncomfortable. My entire arm had the sensation of when your leg or arm falls asleep. I have heard it referred to as pins and needles and that is an accurate description. Today, several hours later, the pain in my shoulder and most of the pain in my arm has already subsided. My finger is a different story. I believe that the pain in my little finger is best described in this manner...have you ever had a Novocain shot while visiting the dentist? My finger feels like I have had an overdose of Novocain in my finger. I do have motor control over my finger, but it seems a little sluggish. When I touch my finger gently against my other fingers, I hardly feel the touch yet I consistently feel the tingling. If I really put pressure on my finger it hurts severely and even though it feels like it is swollen twice its normal size, I can't actually see any difference in size. Interestingly, the sting never made me feel like I needed to stay home from work or change my plans whatsoever but the pain continues even now, eighteen hours later, to affect just about everything I do. I cannot type with my pinky nor can I use the mouse without putting my pinky finger in the air as though I am about to drink some tea at my daughter's tea party. A few days later: When my wife was having her last baby, there was a chart on the wall with the numbers 0-10. There were also pictures next to the numbers that indicated levels of pain.

Even on the first day, immediately after the sting occurred, the pain level was only a 5 or 6. I continued to bring in the presents from the garage but I was careful not to touch anything with my finger. On day two, as I was writing this description, the pain was slightly less acute in the 4-5 range but still affected how I worked and went through my daily routines. On the third day, most of the pain was gone but my finger was still numb and by day 4 or 5, all of the pain had completely subsided. However, it took a few more days for the numbness to completely dissipate. Overall, I would have to say that being stung by a scorpion is quite a bit less frightening than I thought it would be. I have learned a lot from this process and the research I conducted after having been stung. I am happy to share my thoughts and feelings with you in hopes that you learn something too. I hope you enjoyed my article. Brian Farr @briangfarr
