Dangers of Wasp Stings and Wasp Bites

Insects known as Wasps include solitary, parasitic wasps, hornets, and yellow jackets. All of these species aggressively defend their nests.

Wasp Stings

The wasp sting is known to be painful and unpleasant.

Bee Control - Croach - Kirkland, WA - Wasp Sting InformationBesides being painful, wasp stings are itchy, and effects can last from hours to days.

A single sting is not overly dangerous unless you are allergic. The symptoms of an allergic reaction can vary from mild increasing pain and duration to severe, life-threatening issues requiring hospitalization.

Wasps will sting multiple times.

Wasp Bites

Wasp bites are thankfully short-lived. Not known to transmit venom or disease, they often cause more panic than lasting damage.

However, wasp bites commonly occur when the insect latches on to a person or animal to deliver repeated stings. An individual wasp is still rarely more than a nuisance to anyone without allergies. But in groups or swarms, wasps can be hazardous to anyone.

Wasp Sting Properties

Wasp stings cause red skin and small white welts. The welt will have a dot in the middle.

Why are wasp stings so annoying and potentially dangerous?

Outside of the venom, which all have in common, the stings of different wasps have different properties.


Wasp stings, specifically hornets, contain a chemical that affects the brain. It increases our ability to feel pain. An already painful sting becomes more intense, and the sensation lasts longer.

Mimicry Defense

Social wasps sting most often to defend their nest. A wasp sting releases a chemical into the victim that signals others to attack the invader. A single sting can quickly turn into a swarm, up to thousands of wasps in a yellow jacket nest, that becomes a dangerous situation within minutes.


Wasp stingers are modified ovipositors. Parasitic wasps use these to lay eggs on or in the body of other insects or nests. While this stinger is comparatively smooth, some species (yellow jackets and bald face hornets most notably) do have small barbs. They can become lodged in the skin after multiple stings and need to be removed.


If you are stung and have not had a tetanus booster in the last decade, get one.

Wasp Sting Treatment

Allergy levels can vary between stings. For mild reactions, remove the stinger, wash the area with antibacterial soap, apply ice packs, and take Tylenol or Ibuprofen for pain. You can apply a bandage if you want.

For severe reactions, it is recommended that you take an antihistamine and see a doctor as soon as possible. The most severe allergies require treatment with an EpiPen and immediate medical care.
