Cicada Killer Wasp Stings: Painful but Rarely Dangerous

What to Expect from a Cicada Killer Encounter

A landscaper stung by a cicada killer wasp (Sphecius speciosus) faces moderate pain, local redness, and swelling—similar to a honeybee sting. Only females sting; males are aggressive but lack stingers.

Normal Reaction

• Immediate sharp pain, fading to dull ache.
• Red welt, slight swelling, possible itching.
• Resolves in hours to a day.

First Aid

1. Wash with soap and water.
2. Apply meat tenderizer (enzyme breaks down venom) or baking soda paste.
3. OTC sting relief (e.g., Sting-Kill, After Bite).
4. Oral antihistamine (Benadryl) reduces swelling.

Allergic Emergency

If the person has a known insect allergy, watch for:

• Widespread hives, swelling beyond sting site.
• Difficulty breathing, throat tightness, wheezing.
• Dizziness, nausea, vomiting, loss of consciousness.

Call 911 immediately if any systemic symptoms appear. Epinephrine auto-injector (EpiPen) should be used if prescribed.

Prevention

• Cicada killers are solitary; each female digs her own burrow.
• They rarely sting unless stepped on or trapped.
• Control is rarely needed—focus on high-traffic areas only.
