For most scorpion stings in the U.S., home treatment is all that's needed. Wash the sting site immediately with soap and water, apply a cold pack — ice wrapped in a thin cloth, never directly on skin — for 10–20 minutes on and off, elevate the affected limb to heart level, and take acetaminophen or ibuprofen for pain. The American Association of Poison Control Centers confirms this is the correct first response for virtually all non-bark scorpion stings. Do not apply a tourniquet. Do not attempt to suck out venom or cut the sting site. And do not reach for Benadryl or any antihistamine — for reasons that matter enough to be the first H2 below.
Whether you can stay home depends on one factor: species. The Arizona bark scorpion (Centruroides sculpturatus) is the only scorpion in North America whose venom can cause life-threatening systemic illness. It ranges across Arizona, New Mexico, parts of Texas, Nevada, California, and Utah. All other U.S. species cause painful but localized stings that resolve without medical care.
Go to the ER immediately — or call 911 — if the stung person develops muscle twitching, roving eye movements, slurred speech, difficulty swallowing or breathing, excessive salivation, or any change in consciousness. These neurotoxic symptoms typically emerge within 1–3 hours and require antivenom. Children under 6, adults over 65, and anyone with heart or respiratory conditions should be seen by a doctor regardless of which species stung them.
Pain from a typical non-bark sting peaks in the first 2 hours and resolves within 24 hours. Mild tingling or numbness at the sting site can linger 48–72 hours and is considered normal. Symptoms that worsen — rather than improve — after 2–3 hours are a red flag regardless of species.
What You Should Never Do After a Scorpion Sting
Benadryl (diphenhydramine), other antihistamines, and epinephrine (EpiPen) are contraindicated after a scorpion sting and can actively worsen the outcome. This is the most dangerous and most common mistake in scorpion first aid. The instinct to treat a sting like an allergic reaction is understandable — both produce pain, anxiety, and visible distress — but scorpion venom acts through sodium channel toxins, not allergens. Its mechanism is neurological: it forces neurons to over-release neurotransmitters, which drives up heart rate and blood pressure. Antihistamines and epinephrine compound those exact cardiovascular effects. Medical toxicologists at the University of Arizona Health Sciences — the primary U.S. clinical authority on bark scorpion envenomation — explicitly warn against these medications. A tourniquet does not slow venom spread and causes additional tissue injury. Cutting or sucking the sting achieves nothing except added wound risk.
Home vs. Emergency Room: A Decision Framework
Three variables determine whether a scorpion sting needs emergency care: species range, the stung person's age and health, and symptom trajectory. If you are outside known bark scorpion territory and a healthy adult was stung, home care is appropriate. If you are in bark scorpion range — including parts of the Texas Hill Country and trans-Pecos region — and systemic symptoms appear within 3 hours, go to the ER rather than waiting them out. Any sting involving a child under 6 is an emergency department visit, period. The MSD Manual notes that children with severe bark scorpion envenomation (Centruroides grade III or IV) should be admitted to an ICU setting, given how unpredictably symptoms can escalate in smaller bodies.
Call Poison Control at 1-800-222-1222 before making that decision — the line is free, available 24/7, and staffed by toxicologists who can assess your specific situation in real time. That call costs nothing and can prevent both an unnecessary ER trip and a dangerous delay.
What Bark Scorpion Envenomation Actually Looks Like
The bark scorpion (Centruroides sculpturatus, also called Centruroides exilicauda) produces neuromuscular toxicity with a distinctive and rapidly progressing symptom pattern. Initial symptoms are immediate, intense burning at the sting site — often without visible swelling or redness, which is why many people underestimate the sting. The NIH's StatPearls clinical reference notes that of roughly 2,500 scorpion species worldwide, only around 25 are considered lethal to humans, and C. sculpturatus is the sole example in the continental U.S.
Within 1–3 hours, severe bark scorpion envenomation progresses to opsoclonus (roving, uncontrolled eye movements), hypersalivation, muscle twitching, slurred speech, and in young children, respiratory distress. According to Banner Health, bark scorpion stings frequently do not leave a visible mark — even clinical staff often cannot locate the puncture wound, which is why pain and behavioral symptoms are the primary diagnostic signals.
Keeping Scorpions Out of Your Home
Long-term scorpion control requires removing both harborage sites and structural entry points — chemical treatment alone is rarely sufficient. Scorpions are nocturnal predators that shelter in crevices, under rocks, inside firewood stacks, and within footwear during the day. Eliminating these harborage opportunities significantly reduces interior sightings. Apply weather-stripping around doors and windows, seal gaps around utility penetrations, repair torn screens, and store firewood away from the exterior wall. Shake out shoes, clothing, and bedding routinely in areas where scorpions are common.
In Central Texas and the Southwest, where the bark scorpion's range overlaps with suburban neighborhoods, professional pest management provides a layer of protection that exclusion work alone cannot match. For homeowners already navigating multiple pest pressures, understanding the full scope of bug termite and pest control strategies helps prioritize where treatment is needed most.
What Antivenom Is and When It's Used
Anascorp® (Centruroides immune F(ab')₂) is the FDA-approved antivenom for bark scorpion envenomation; it works by binding and neutralizing venom in the bloodstream, with symptoms typically resolving rapidly after administration. Antivenom is indicated when a patient shows severe neuromuscular or cranial nerve dysfunction — slurred speech, abnormal eye movements, muscle loss of control — that cannot be managed with supportive care alone. It is most effective when given early, before the full symptom burden develops, which is why young children in bark scorpion territory should be evaluated without delay rather than monitored at home.
For non-bark scorpion stings, antivenom is not relevant. The MSD Manual Professional Edition notes that non-venomous stings are managed with an ice pack and oral NSAIDs, with benzodiazepines reserved for significant muscle spasm. Tetanus prophylaxis should also be considered if the stung person's vaccination is not current.
How Long Does a Scorpion Sting Hurt?
The pain timeline is predictable and tied directly to species. For non-dangerous species, sharp pain is worst in the first 2 hours and begins fading by hour 6. Most symptoms resolve within 24 hours at the sting site, per Seattle Children's Hospital. Mild tingling or numbness can persist 48–72 hours and is not a sign of worsening. For bark scorpion stings managed without antivenom, pain may remain significant for 12–48 hours and systemic symptoms can continue developing for up to 24 hours after the sting. The key monitoring window is the first 2–4 hours: if symptoms are improving during that period, you are likely past the peak risk. If they are worsening, that trajectory requires immediate medical evaluation regardless of how mild the initial pain seemed.
When Professional Pest Control Becomes Necessary
A single scorpion found in the home is a manageable event. A recurring pattern is not.
Scorpions do not appear indoors frequently by accident. Multiple sightings or stings within a single season indicate an established population with accessible harborage and entry points on or near the structure. Consider professional pest assessment if any of the following apply to your situation:
- Scorpions found inside the home more than twice in one season
- Scorpions discovered in a child's bedroom, crib area, or play space
- Stings occurring despite consistent use of weather-stripping and preventive shoe-shaking
- Property is adjacent to rocky terrain, dry creek beds, or vacant lots in bark scorpion range
- The home is older construction with known gaps around utility penetrations or foundation cracks
- A sting has already resulted in an emergency room visit or antivenom treatment
If two or more of these match your situation, a licensed pest professional can identify specific harborage sites, seal structural entry points, and apply targeted treatment in a way that broad DIY spraying cannot replicate. Residents in the New Braunfels and Temple corridor can find pest control temple services nearby, and those in the Austin metro area can locate pest control near me options that cover the full Central Texas region.

FAQ
Q: How do you know if a scorpion sting is serious?
A: A sting is serious if systemic symptoms appear within 1–3 hours: muscle twitching, roving or uncontrolled eye movements (opsoclonus), slurred speech, difficulty swallowing or breathing, or changes in consciousness. Local pain and numbness alone — without these symptoms — indicate a non-dangerous sting. Children under 6 and adults over 65 should be evaluated by a doctor regardless of symptom severity.
Q: Can you die from a scorpion sting in the United States?
A: Death is extremely rare. According to Cleveland Clinic, no scorpion sting fatality has been reported in the U.S. in more than 50 years. The only U.S. species with potentially fatal venom is the bark scorpion (Centruroides sculpturatus), and fatalities are almost exclusively limited to very young children who do not receive prompt medical care.
Q: Should I call Poison Control after any scorpion sting?
A: Yes, and it costs nothing. Poison Control (1-800-222-1222) is staffed 24/7 by toxicologists who can assess severity in real time based on your symptoms, the stung person's age, and your location. For any child stung in bark scorpion territory, call immediately rather than waiting to see how symptoms develop.
Q: Do scorpion stings always leave a visible mark?
A: No. The bark scorpion's stinger is small enough that the puncture wound is frequently invisible — Banner Health notes that even medical staff in clinical settings are often unable to locate the sting site. Absence of a visible mark does not mean a sting did not occur or that it is not serious.
Q: How long does numbness last after a scorpion sting?
A: For most non-dangerous stings, numbness and tingling at the sting site fade within 24 hours, per Seattle Children's Hospital. Residual mild tingling can persist 48–72 hours and is considered normal. Numbness that spreads up a limb or is accompanied by muscle twitching indicates a more serious reaction requiring prompt medical evaluation.
Quick Reference: Scorpion Sting Treatment
- Immediate first aid for any scorpion sting: wash with soap and water, apply an ice-wrapped cold pack for 10–20 minutes on and off, elevate the limb, and take acetaminophen or ibuprofen for pain.
- Do not take Benadryl, any antihistamine, or use an EpiPen — scorpion venom is neurotoxic, not allergic, and these medications can worsen elevated heart rate and blood pressure.
- The Arizona bark scorpion (Centruroides sculpturatus) is the only North American species whose venom can cause life-threatening systemic illness; all other U.S. species cause localized stings.
- Call 911 or go to the ER if muscle twitching, roving eye movements, slurred speech, or breathing difficulty develops — these neurotoxic symptoms typically emerge within 1–3 hours of a bark scorpion sting.
- Children under 6, adults over 65, and anyone with heart or respiratory conditions should be seen by a doctor after any scorpion sting, regardless of species.
- Most non-bark scorpion stings resolve within 24 hours; mild numbness or tingling at the sting site can persist 48–72 hours and is a normal part of recovery.
- Poison Control (1-800-222-1222) provides free, real-time triage guidance 24/7 — call before deciding whether to go to the ER.
- Recurring indoor scorpion activity — two or more sightings per season — warrants professional pest inspection to identify harborage sites and seal structural entry points.
