Everything you need to know about scorpion stings

Scorpions tend to spark fear, mostly because of how they look and how they're portrayed in movies and TV shows. Their stingers, in particular, make people nervous. The truth is, most scorpions don’t pose a serious risk to people and only sting when they feel threatened.

That said, Arizona is home to the Arizona bark scorpion, which is considered the most venomous species in North America. While the risk is low for most, it's still important to understand when and why stings happen, what to watch for, and how to respond.

 

Why do scorpions sting?

Scorpions sting as a defense mechanism. They only have a limited amount of venom within their system. If their prey is small enough, they can use their claws to grab it and tear it apart to eat it. However, to paralyze larger prey, they will lunge their tail forward and sting their prey to immobilize it and then eat it.

While they may use their venom to subdue prey, they usually only sting humans if they feel threatened or are handled. The pain from scorpion stings can be intense, but in most cases, they’re not life-threatening. If you have been stung by a scorpion and you’re worried about any symptoms, you should seek medical attention immediately.

Trying to pick up or disturb a scorpion increases the risk of being stung. If you see one, the safest course of action is to leave it alone and avoid contact.

How to avoid scorpion stings

Scorpions want to avoid people as much as possible, but sometimes they end up inside homes and crawling along walls outside homes, too. Ensuring the house is sealed up and there is no way for scorpions to crawl inside can help prevent scorpion infestations and is the best way to avoid being stung in your home. Checking clothing and shoes before putting them on in scorpion-heavy areas is important, too. Learn more about how to get rid of scorpions.

How does scorpion venom affect humans?

Scorpion venom affects people in different ways, and not everyone reacts in the same manner. Some experience mild pain, while others may develop more severe symptoms. Factors like age, allergies, or underlying health conditions, such as heart or respiratory issues, can influence how someone responds. In rare cases, people may experience an allergic reaction. Because reactions vary, it's important to monitor symptoms closely and seek medical attention if you're concerned.

 

Scorpion sting symptoms

If you are stung by a scorpion, you will most likely feel the sting. It is very similar to a bee sting and may feel like an intense, sharp pain. Scorpion sting symptoms may include:

  • Intense pain around the sting site
  • Tingling or numbness centered around the sting site
  • Swelling around the spot where you were stung

People who have an allergic reaction to the scorpion sting may also experience:

  • Difficulty breathing
  • Muscle spasms
  • Drooling
  • Vomiting or intense nausea
  • Fever
  • Heart palpitations or increased blood pressure
  • Strange movements of the head or neck
  • Sudden crying or restlessness, most often seen in children

This list is not exhaustive, and should not be taken as medical advice. If you experience any of the symptoms listed here, or experience other symptoms you’re worried about, seek medical attention immediately. 

 

How do you treat a scorpion sting?

If you are stung by a scorpion, it is best to seek medical attention and monitor your symptoms. If you can give information about the scorpion or provide a picture, the doctors might be able to provide a more effective treatment.
